Objectifs :

This tutorial aims to deepen your understanding of using flows in Power Automate by introducing essential concepts such as variables and loops. You will learn how to create a monthly scheduled flow that lists all files stored at the root of a team's channel and publishes them as clickable items in a message.


Chapitres :

  1. Introduction to Flows
    In this tutorial, we will explore the essential concepts of variables and loops in Power Automate. These concepts are crucial for enhancing your use of flows, particularly when creating automated processes.
  2. Creating a Monthly Scheduled Flow
    We will create a monthly scheduled flow with the goal of listing all files stored at the root of a team's channel. The final output will be a message containing clickable items representing these files.
  3. Defining Recurrence
    Start by defining the recurrence for your flow. This sets the schedule for how often the flow will run.
  4. Retrieving Files from SharePoint
    Choose the action to retrieve files from a team's channel, which is associated with SharePoint. Select the 'Get files' action and configure the relevant team's site and library. Make sure to enable advanced settings to list only the files at the root of a specific channel, excluding subfolders.
  5. Understanding Variables
    Variables are temporary storage elements used to hold data during the execution of a flow. They allow for storing intermediate values, maintaining states, and facilitating complex calculations.
  6. Initializing a Variable
    To store the list of files, initialize a text variable by calling the initialization action. Name your variable and define its type as 'string' to store character strings. You do not need to enter a default value.
  7. Populating the Variable
    Populate your variable with the list of files from your channel. Look for a command to add items to your string variable and define your file list variable as the element to be populated with file names.
  8. Using Loops to Process Files
    Power Automate generates a 'for each' processing loop, allowing each item to be processed individually. The variable will need to be populated as many times as there are files in the team's channel.
  9. Creating Clickable Links
    To make each item clickable, inject HTML to generate links. Use an 'A' tag pointing to the file link via dynamic content, along with the full file name for the text of your link. Add a 'BR' tag for line breaks between each item.
  10. Defining the Message
    Define a message from predefined items that will contain your variable populated by the loop. Create a team's post in a specific channel containing the content of your message.
  11. Testing the Flow
    Save and test your flow. Initially, the message may include not only the root files but also folders, which may not be desired.
  12. Modifying the Flow
    To exclude folders from the listed items, modify your flow by adding a filter query element to the 'Get files' action. This command is specific but easily retrievable online.
  13. Final Testing
    Test your flow again. This time, the list should be more compact and exclude folders, demonstrating a simple approach to using a variable associated with a processing loop in a Power Automate flow.

FAQ :

What is a flow in Power Automate?

A flow in Power Automate is an automated workflow that connects different applications and services to perform tasks automatically, reducing the need for manual intervention.

How do I create a variable in Power Automate?

To create a variable in Power Automate, use the 'Initialize variable' action, give it a name, define its type (e.g., string), and optionally set a default value.

What is the purpose of loops in a flow?

Loops in a flow allow you to process multiple items individually by repeating a set of actions for each item until all items have been processed.

How can I exclude folders when retrieving files from SharePoint?

To exclude folders when retrieving files from SharePoint in Power Automate, you can add a filter query to the 'Get files' action to specify that only files should be listed.

What is the significance of using HTML in Power Automate?

Using HTML in Power Automate allows you to format messages, create clickable links, and enhance the presentation of information in notifications or messages sent through flows.

Can I test my flow after creating it?

Yes, you can test your flow after creating it to ensure it functions as expected. You can save and run the flow to see the results and make any necessary adjustments.


Quelques cas d'usages :

Automating File Retrieval from SharePoint

In a corporate environment, a team can use Power Automate to create a flow that automatically retrieves and lists all files from a specific SharePoint channel. This can save time and ensure that team members have easy access to important documents without manually searching through folders.

Generating Clickable Reports

A marketing team can utilize Power Automate to generate a report that lists all campaign files as clickable links in a message. This allows team members to quickly access relevant documents directly from the report, improving efficiency in project management.

Scheduled Notifications for File Updates

An IT department can set up a scheduled flow that checks for new files in a SharePoint channel every month and sends a notification to the team with a list of new files. This ensures that everyone stays updated on the latest resources available.

Excluding Unwanted Items in File Lists

When creating a flow to list files, a project manager can implement a filter query to exclude folders from the list. This ensures that the team only sees relevant files, making it easier to find what they need without clutter.


Glossaire :

Flow

A flow is an automated workflow that connects different applications and services to perform tasks without manual intervention.

Variables

Variables are temporary storage elements used to hold data that can be modified during the execution of a flow. They allow for storing intermediate values and maintaining states.

Loops

Loops are programming constructs that repeat a set of instructions until a specified condition is met. In flows, they allow for processing multiple items individually.

SharePoint

SharePoint is a web-based collaboration platform that integrates with Microsoft Office. It is used for storing, organizing, sharing, and accessing information from any device.

HTML

HTML (HyperText Markup Language) is the standard markup language for documents designed to be displayed in a web browser. It is used to create web pages and applications.

HARF

HARF appears to be a typo; it likely refers to 'href', which is an HTML attribute used to specify the URL of the page the link goes to.

Power Automate

Power Automate is a cloud-based service that allows users to create automated workflows between applications and services to synchronize files, get notifications, collect data, and more.

00:00:07
This is what we will cover in this tutorial,
00:00:09
particularly by introducing the principle of variables and loops
00:00:15
to best illustrate these concepts.
00:00:17
Let's create a monthly scheduled flow with the goal of listing all files stored at
00:00:21
the root of a team's channel and publishing the list as clickable items in a message
00:00:28
start by defining the recurrence.
00:00:30
Then choose the action to retrieve the files from a team's channel
00:00:34
which is of course associated with sharepoint by selecting the get files action
00:00:39
configure the relevant team's team and library.
00:00:45
Make sure to enable advanced settings if necessary such
00:00:48
as here where you want to list only the files
00:00:50
at the root of a specific channel without including
00:00:53
the content of the sub folders of this channel,
00:00:56
check the appropriate options,
00:01:00
then point to the relevant folder specifying not to include nested sub folders.
00:01:06
The final objective being to publish a single message containing all the files,
00:01:11
we will need to use a variable.
00:01:13
But what is a variable?
00:01:15
Variables are temporary storage elements used to hold your data
00:01:19
which can be used and modified during the execution of a flow.
00:01:23
They allow for storing intermediate values,
00:01:25
maintaining states and facilitating for example,
00:01:28
complex calculations within a flow.
00:01:32
Let's see how to proceed.
00:01:34
You will generate a text string containing the list of files,
00:01:38
initialize a text variable by calling the
00:01:41
initialization action via the variable keyword.
00:01:46
Give a name to your variable that you will reuse. Later
00:01:50
define the type as string which will store a character string.
00:01:53
You do not need to enter a default value in this case.
00:01:57
Now populate your variable so that it contains the list of files from your channel.
00:02:01
Do not forget to look for a command to add items to your string variable.
00:02:07
Now define your file list variable as the element to be populated.
00:02:11
Indicate that this variable will contain the file name.
00:02:15
Since there are numerous files present in the channel.
00:02:18
Recall that the SharePoint action at the start is called get files.
00:02:22
Power automate generates a for each processing loop
00:02:25
allowing each item to be processed individually.
00:02:28
And recurrently
00:02:29
indeed,
00:02:29
the variable will need to be populated as many
00:02:32
times as there are files in the team's channel.
00:02:36
To make each item clickable, you can inject some html to generate the links.
00:02:40
Use an HARF
00:02:41
tag pointing to the file link via dynamic contents as well
00:02:45
as the full file name for the text of your link.
00:02:48
Add a BR tag for a line break between each edition.
00:02:51
This syntax is quite simple but requires some knowledge of html
00:02:56
define a message from predefined items that will
00:02:59
contain your variable populated by the loop.
00:03:04
Finally create a team's post in a specific channel containing the
00:03:08
content of your message action generated in the previous action,
00:03:14
save and test your flow.
00:03:21
Although functional,
00:03:22
the message includes not only the root files of the
00:03:24
channel but also the folders which is not necessarily desired.
00:03:29
Therefore modify your flow by adding to the get files action,
00:03:33
a filter query element to exclude folders from the listed items.
00:03:37
The command is quite specific but easily retrievable on the internet.
00:03:42
Test your flow again,
00:03:43
this time, the list is more compact and excludes folders.
00:03:47
This is a simple approach related to using a variable
00:03:49
associated with a processing loop in a power automate flow.

00:00:02
Quando deseja aprofundar o uso dos fluxos, certos conceitos são essenciais.
00:00:07
Isto é o que abordaremos neste tutorial,
00:00:09
nomeadamente através da introdução do princípio das variáveis e loops
00:00:15
para melhor ilustrar estes conceitos.
00:00:17
Vamos criar um fluxo programado mensal com o objetivo de listar todos os ficheiros armazenados em
00:00:21
a raiz do canal de uma equipa e a publicação da lista como itens clicáveis numa mensagem
00:00:28
começar por definir a recorrência.
00:00:30
Em seguida, escolha a ação para recuperar os ficheiros do canal de uma equipa
00:00:34
que está obviamente associado ao sharepoint selecionando a ação de obter ficheiros
00:00:39
configurar a equipa relevante e a biblioteca da equipa.
00:00:45
Certifique-se de activar as definições avançadas, se necessário
00:00:48
como aqui onde deseja listar apenas os ficheiros
00:00:50
na raiz de um canal específico sem incluir
00:00:53
o conteúdo das subpastas deste canal,
00:00:56
verificar as opções adequadas,
00:01:00
em seguida, aponte para a pasta relevante especificando não incluir subpastas aninhadas.
00:01:06
O objectivo final é publicar uma única mensagem contendo todos os ficheiros,
00:01:11
teremos de utilizar uma variável.
00:01:13
Mas o que é uma variável?
00:01:15
As variáveis são elementos de armazenamento temporário utilizados para guardar os seus dados
00:01:19
que podem ser utilizados e modificados durante a execução de um caudal.
00:01:23
Permitem armazenar valores intermédios,
00:01:25
a manutenção dos Estados e a facilitação, por exemplo,
00:01:28
cálculos complexos dentro de um fluxo.
00:01:32
Vamos ver como proceder.
00:01:34
Irá gerar uma cadeia de texto contendo a lista de ficheiros,
00:01:38
inicializar uma variável de texto chamando o
00:01:41
ação de inicialização através da palavra-chave variável.
00:01:46
Dê um nome à sua variável que irá reutilizar. Mais tarde
00:01:50
definir o tipo como string que irá armazenar uma cadeia de caracteres.
00:01:53
Neste caso, não é necessário introduzir um valor predefinido.
00:01:57
Agora preencha a sua variável para que ela contenha a lista de ficheiros do seu canal.
00:02:01
Não se esqueça de procurar um comando para adicionar itens à sua variável string.
00:02:07
Agora defina a sua variável de lista de ficheiros como o elemento a preencher.
00:02:11
Indique que esta variável conterá o nome do ficheiro.
00:02:15
Uma vez que existem inúmeros ficheiros presentes no canal.
00:02:18
Recorde que a acção do SharePoint no início chama-se obter ficheiros.
00:02:22
O Power Automate gera um para cada loop de processamento
00:02:25
permitir que cada item seja processado individualmente.
00:02:28
E recorrentemente
00:02:29
com efeito,
00:02:29
a variável terá de ser preenchida com tantas
00:02:32
vezes em que existem ficheiros no canal da equipa.
00:02:36
Para tornar cada item clicável, pode injetar algum html para gerar os links.
00:02:40
Utilizar um HARF
00:02:41
tag apontando para o link do arquivo também através de conteúdos dinâmicos
00:02:45
como o nome completo do ficheiro para o texto da sua hiperligação.
00:02:48
Adicione uma etiqueta BR para uma quebra de linha entre cada edição.
00:02:51
Esta sintaxe é bastante simples mas requer algum conhecimento de html
00:02:56
definir uma mensagem a partir de itens predefinidos que irão
00:02:59
contém a sua variável preenchida pelo loop.
00:03:04
Por fim, crie o post de uma equipa num canal específico contendo
00:03:08
conteúdo da ação da sua mensagem gerada na ação anterior,
00:03:14
salve e teste o seu fluxo.
00:03:21
Apesar de funcional,
00:03:22
a mensagem inclui não só os ficheiros raiz do
00:03:24
canal mas também as pastas que não são necessariamente desejadas.
00:03:29
Por conseguinte, modifique o seu fluxo adicionando à acção get files,
00:03:33
um elemento de consulta de filtro para excluir pastas dos itens listados.
00:03:37
O comando é bastante específico mas facilmente recuperável na internet.
00:03:42
Teste novamente o seu fluxo,
00:03:43
desta vez, a lista é mais compacta e exclui pastas.
00:03:47
Trata-se de uma abordagem simples relacionada com a utilização de uma variável
00:03:49
associado a um ciclo de processamento num fluxo automático de energia.

00:00:02
Quando si desidera approfondire l'uso dei flussi, alcuni concetti sono essenziali.
00:00:07
Questo è ciò che tratteremo in questo tutorial,
00:00:09
in particolare introducendo il principio delle variabili e dei cicli
00:00:15
per illustrare al meglio questi concetti.
00:00:17
Creiamo un flusso pianificato mensile con l'obiettivo di elencare tutti i file archiviati in
00:00:21
la cartella principale del canale di un team e pubblicando l'elenco come elementi cliccabili in un messaggio
00:00:28
inizia definendo la ricorrenza.
00:00:30
Quindi scegli l'azione per recuperare i file dal canale di un team
00:00:34
che è ovviamente associato a sharepoint selezionando l'azione get files
00:00:39
configura il team e la libreria del team pertinente.
00:00:45
Assicurati di abilitare le impostazioni avanzate, se necessario
00:00:48
come qui dove vuoi elencare solo i file
00:00:50
nella radice di un canale specifico senza includere
00:00:53
il contenuto delle sottocartelle di questo canale,
00:00:56
controlla le opzioni appropriate,
00:01:00
quindi punta alla cartella pertinente specificando di non includere le sottocartelle annidate.
00:01:06
L'obiettivo finale è pubblicare un singolo messaggio contenente tutti i file,
00:01:11
avremo bisogno di usare una variabile.
00:01:13
Ma cos'è una variabile?
00:01:15
Le variabili sono elementi di archiviazione temporanei utilizzati per contenere i dati
00:01:19
che possono essere utilizzati e modificati durante l'esecuzione di un flusso.
00:01:23
Consentono di memorizzare valori intermedi,
00:01:25
mantenere gli stati e facilitare, ad esempio,
00:01:28
calcoli complessi all'interno di un flusso.
00:01:32
Vediamo come procedere.
00:01:34
Genererai una stringa di testo contenente l'elenco dei file,
00:01:38
inizializza una variabile di testo chiamando
00:01:41
azione di inizializzazione tramite la parola chiave variabile.
00:01:46
Dai un nome alla tua variabile che riutilizzerai. Più tardi
00:01:50
definisci il tipo come stringa che memorizzerà una stringa di caratteri.
00:01:53
In questo caso non è necessario immettere un valore predefinito.
00:01:57
Ora compila la variabile in modo che contenga l'elenco dei file del tuo canale.
00:02:01
Non dimenticate di cercare un comando per aggiungere elementi alla variabile stringa.
00:02:07
Ora definisci la variabile dell'elenco dei file come elemento da popolare.
00:02:11
Indica che questa variabile conterrà il nome del file.
00:02:15
Poiché nel canale sono presenti numerosi file.
00:02:18
Ricordiamo che l'azione iniziale di SharePoint si chiama get files.
00:02:22
Power automate genera un ciclo di elaborazione per ogni ciclo di elaborazione
00:02:25
permettendo a ciascun articolo di essere elaborato singolarmente.
00:02:28
E ricorrentemente
00:02:29
anzi
00:02:29
la variabile dovrà essere popolata altrettante
00:02:32
volte man mano che ci sono file nel canale del team.
00:02:36
Per rendere ogni elemento cliccabile, puoi inserire del codice html per generare i link.
00:02:40
Usa un HARF
00:02:41
tag che punta al collegamento del file anche tramite contenuti dinamici
00:02:45
come nome completo del file per il testo del link.
00:02:48
Aggiungi un tag BR per un'interruzione di riga tra ogni edizione.
00:02:51
Questa sintassi è abbastanza semplice ma richiede una certa conoscenza dell'html
00:02:56
definisci un messaggio da elementi predefiniti che lo farà
00:02:59
conterrà la variabile popolata dal ciclo.
00:03:04
Infine, crea il post di un team in un canale specifico contenente
00:03:08
contenuto dell'azione del messaggio generata nell'azione precedente,
00:03:14
salva e testa il flusso.
00:03:21
Sebbene funzionale,
00:03:22
il messaggio include non solo i file root di
00:03:24
canale ma anche le cartelle che non sono necessariamente desiderate.
00:03:29
Quindi modifica il flusso aggiungendo all'azione get files,
00:03:33
un elemento di interrogazione del filtro per escludere le cartelle dagli elementi elencati.
00:03:37
Il comando è abbastanza specifico ma facilmente recuperabile su Internet.
00:03:42
Metti nuovamente alla prova il tuo flusso,
00:03:43
questa volta, l'elenco è più compatto ed esclude le cartelle.
00:03:47
Si tratta di un approccio semplice relativo all'uso di una variabile
00:03:49
associato a un ciclo di elaborazione in un flusso di alimentazione automatica.

00:00:02
Если вы хотите углубить использование потоков, вам понадобятся определенные концепции.
00:00:07
Это то, что мы рассмотрим в этом уроке,
00:00:09
в частности, введя принцип переменных и циклов
00:00:15
чтобы лучше всего проиллюстрировать эти концепции.
00:00:17
Давайте создадим ежемесячный запланированный поток с целью перечисления всех файлов, хранящихся на
00:00:21
в корне канала команды и публикация списка в виде кликабельных элементов в сообщении
00:00:28
начните с определения повторяемости.
00:00:30
Затем выберите действие по извлечению файлов из канала команды
00:00:34
что, конечно, связано с sharepoint, выбрав действие «Получить файлы»
00:00:39
настройте команду и библиотеку соответствующей команды.
00:00:45
Обязательно включите дополнительные настройки, если это необходимо
00:00:48
как здесь, где вы хотите перечислить только файлы
00:00:50
в корне определенного канала без включения
00:00:53
содержимое подпапок этого канала,
00:00:56
отметьте подходящие опции,
00:01:00
затем укажите на соответствующую папку, указав, что не следует включать вложенные подпапки.
00:01:06
Конечная цель состоит в том, чтобы опубликовать одно сообщение, содержащее все файлы,
00:01:11
нам нужно будет использовать переменную.
00:01:13
Но что такое переменная?
00:01:15
Переменные — это временные элементы хранения, используемые для хранения данных
00:01:19
которые можно использовать и изменять во время выполнения потока.
00:01:23
Они позволяют хранить промежуточные значения,
00:01:25
поддержание состояний и содействие, например,
00:01:28
сложные вычисления в потоке.
00:01:32
Давайте посмотрим, как действовать дальше.
00:01:34
Вы создадите текстовую строку со списком файлов,
00:01:38
инициализируйте текстовую переменную, вызвав
00:01:41
действие инициализации с помощью ключевого слова variable.
00:01:46
Дайте переменной имя для повторного использования. Позже
00:01:50
определите тип в виде строки, в которой будет храниться строка символов.
00:01:53
В этом случае вводить значение по умолчанию не нужно.
00:01:57
Теперь заполните переменную так, чтобы она содержала список файлов из вашего канала.
00:02:01
Не забудьте найти команду для добавления элементов в строковую переменную.
00:02:07
Теперь определите переменную списка файлов в качестве элемента, который нужно заполнить.
00:02:11
Укажите, что эта переменная будет содержать имя файла.
00:02:15
Поскольку в канале представлено множество файлов.
00:02:18
Напомним, что действие SharePoint в начале называется get files.
00:02:22
Power Automate генерирует код для каждого цикла обработки
00:02:25
что позволяет обрабатывать каждую единицу по отдельности.
00:02:28
И периодически
00:02:29
действительно,
00:02:29
переменную нужно будет заполнить как можно больше
00:02:32
раз больше файлов, чем в канале команды.
00:02:36
Чтобы сделать каждый элемент интерактивным, вы можете вставить несколько html-файлов для создания ссылок.
00:02:40
Используйте HARF
00:02:41
тег, указывающий также на ссылку на файл с помощью динамического содержимого
00:02:45
в качестве полного имени файла для текста вашей ссылки.
00:02:48
Добавьте тег BR для разрыва строк между каждым изданием.
00:02:51
Этот синтаксис довольно прост, но требует некоторых знаний html
00:02:56
определите сообщение из предопределенных элементов, которое будет
00:02:59
содержать переменную, заполненную циклом.
00:03:04
Наконец, создайте пост команды в определенном канале, содержащем
00:03:08
содержимое вашего действия с сообщением, созданного в предыдущем действии,
00:03:14
сохраните и протестируйте свой поток.
00:03:21
Несмотря на функциональность,
00:03:22
сообщение включает не только корневые файлы
00:03:24
канал, но и папки, которые не обязательно нужны.
00:03:29
Поэтому измените свой процесс, добавив в команду действие «Получить файлы»,
00:03:33
элемент запроса фильтра для исключения папок из списка.
00:03:37
Команда довольно специфична, но ее легко найти в Интернете.
00:03:42
Еще раз протестируйте свой поток,
00:03:43
на этот раз список более компактный и исключает папки.
00:03:47
Это простой подход, связанный с использованием переменной
00:03:49
связано с циклом обработки в потоке автоматизации электропитания.

Cuando desee profundizar en el uso de los flujos, ciertos conceptos son esenciales.
00:00:07
Esto es lo que trataremos en este tutorial,
00:00:09
particularmente mediante la introducción del principio de variables y bucles
00:00:15
para ilustrar mejor estos conceptos.
00:00:17
Vamos a crear un flujo programado mensual con el objetivo de enumerar todos los archivos almacenados en
00:00:21
la raíz del canal de un equipo y publicar la lista como elementos en los que se puede hacer clic en un mensaje
00:00:28
empieza por definir la recurrencia.
00:00:30
A continuación, elige la acción para recuperar los archivos del canal de un equipo
00:00:34
que, por supuesto, se asocia a SharePoint al seleccionar la acción «obtener archivos»
00:00:39
configura el equipo y la biblioteca del equipo correspondiente.
00:00:45
Asegúrese de habilitar la configuración avanzada si es necesario, como
00:00:48
como aquí donde quieres listar solo los archivos
00:00:50
en la raíz de un canal específico sin incluir
00:00:53
el contenido de las subcarpetas de este canal,
00:00:56
compruebe las opciones apropiadas,
00:01:00
a continuación, señale la carpeta correspondiente especificando que no desea incluir subcarpetas anidadas.
00:01:06
El objetivo final es publicar un único mensaje que contenga todos los archivos,
00:01:11
necesitaremos usar una variable.
00:01:13
Pero, ¿qué es una variable?
00:01:15
Las variables son elementos de almacenamiento temporal que se utilizan para almacenar los datos
00:01:19
que se pueden usar y modificar durante la ejecución de un flujo.
00:01:23
Permiten almacenar valores intermedios,
00:01:25
mantener estados y facilitar, por ejemplo,
00:01:28
cálculos complejos dentro de un flujo.
00:01:32
Vamos a ver cómo proceder.
00:01:34
Generará una cadena de texto que contiene la lista de archivos,
00:01:38
inicialice una variable de texto llamando al
00:01:41
acción de inicialización mediante la palabra clave variable.
00:01:46
Asigne un nombre a la variable que va a reutilizar. Más tarde
00:01:50
defina el tipo como cadena que almacenará una cadena de caracteres.
00:01:53
En este caso, no es necesario introducir un valor predeterminado.
00:01:57
Ahora rellena la variable para que contenga la lista de archivos de tu canal.
00:02:01
No olvides buscar un comando para añadir elementos a tu variable de cadena.
00:02:07
Ahora defina la variable de la lista de archivos como el elemento a rellenar.
00:02:11
Indique que esta variable contendrá el nombre del archivo.
00:02:15
Ya que hay numerosos archivos presentes en el canal.
00:02:18
Recuerde que la acción de SharePoint al principio se denomina obtener archivos.
00:02:22
Power Automate genera un bucle de procesamiento para cada ciclo
00:02:25
lo que permite que cada artículo se procese de forma individual.
00:02:28
Y de forma recurrente
00:02:29
de hecho,
00:02:29
la variable tendrá que rellenarse tantos
00:02:32
veces que haya archivos en el canal del equipo.
00:02:36
Para que se pueda hacer clic en cada elemento, puedes inyectar algo de código HTML para generar los enlaces.
00:02:40
Usa un HARF
00:02:41
También es una etiqueta que apunta al enlace del archivo a través del contenido dinámico
00:02:45
como el nombre de archivo completo del texto de tu enlace.
00:02:48
Agregue una etiqueta BR para un salto de línea entre cada edición.
00:02:51
Esta sintaxis es bastante simple, pero requiere algunos conocimientos de HTML
00:02:56
defina un mensaje a partir de elementos predefinidos que
00:02:59
contendrá su variable rellenada por el bucle.
00:03:04
Por último, crea una publicación de equipo en un canal específico que contenga el
00:03:08
contenido de la acción de tu mensaje generada en la acción anterior,
00:03:14
guarda y prueba tu flujo.
00:03:21
Aunque es funcional,
00:03:22
el mensaje incluye no solo los archivos raíz del
00:03:24
el canal, sino también las carpetas, lo que no es necesariamente deseado.
00:03:29
Por lo tanto, modifique su flujo añadiendo a la acción obtener archivos,
00:03:33
un elemento de consulta de filtro para excluir carpetas de los elementos de la lista.
00:03:37
El comando es bastante específico, pero se puede recuperar fácilmente en Internet.
00:03:42
Vuelva a probar su flujo,
00:03:43
esta vez, la lista es más compacta y excluye las carpetas.
00:03:47
Se trata de un enfoque sencillo relacionado con el uso de una variable
00:03:49
asociado a un bucle de procesamiento en un flujo de automatización de energía.
