Actionflow Fundamentals

Actionflow: Implement complex logic by adding, deleting, modifying, querying data, writing JS code blocks, calling APIs, and conditional branching.

Introduction

Building in Momen is like building Legos. However, you can not build a smooth sphere. There are always some functions that can not be built by the existing components and actions in Momen.

For example:

• Randomly draw a question from the question bank that the current user has not done;

• Change the order status to "transaction expired" every minute if it has been "pending" for more than 15 minutes

• Encapsulate the commands to operate the database into API for external calls, such as operating the database after payment.

These functions need to rely on Momen's action flow to complete. We can understand Momen's action flow as a function or API. Given an input, it executes the corresponding actions, and returns an output. The logic of execution is written by us.

Cautions

• Action flow does not use strict type checking so that you can assign a [text] variable to a [integer] variable.

• Before deleting a node, first delete the output of the node that will be used later.

Concept of ActionFlow Versions

Tips:

• ActionFlow won't be saved automatically. Make sure to click Save in the upper right corner. Otherwise, the latest Action Flow will not be executed.

• After each save, the version will be updated.

• Callbacks and timed triggers execute the latest version of the deployed backend.

Example:

• The version executed in your app is version 1.

• The version executed by callbacks and timed triggers is version 2.

Action Flow Configuration Entrance

Click the [Action Flow] button in the upper left corner of the editor to enter the action flow creation page.

Creating an ActionFlow

Click the [Add] button on the left side of the action flow creation page to create an action flow.

Configuring an ActionFlow

A complete action flow configuration consists of three parts: configuring input parameters, action operations/branches, and configuring output parameters.

Configuring Input Parameters

If your actionflow is to further process the data entered by the user or generated by the front-end page logic, you need to click the [Input] button at the top of the action flow to add input parameters. It is recommended to rename the parameters and select the appropriate data type.

Concepts of Nodes, Operations and Branches

Nodes

Each [+] sign in the actionflow represents a [node], in each node you can use the result data generated by the parent node.

For example: you can directly refer to actionflow data as the filter condition to update the same data.

Operations

Actions to be performed in the actionflow. The order of execution of operations is from top to bottom.

Branching

When executing different operations under different conditions, you can add branches to set the judgment conditions, the judgment order of the conditions is from left to right, and there are at least two branches when adding.

Adding Actions

In order to realize various business requirements, the following seven operations can be configured in the action flow.

Query Data

After adding this operation, when running the actionflow, you can configure filtering conditions, de-emphasis, sorting, and directly read one or more pieces of data in the data table, and the acquired data can be used in other operations or branches of the subsequent action flow.

Delete Data

After adding this action, data that meets the filter criteria will be deleted when the action flow is run.

Update Data

When this action is added, the act of updating the data in a table that meets the filter criteria is performed when the action flow is run.

Insert Data

This action will add one piece of data to a table, and when you turn on the batch operation, then you can add multiple items.

Custom Code

JS code can be edited in the actionflow to implement more complex logic.

Third-party APIs

You can call APIs to get/modify external data in the actionflow.

Configuration Output

If you need to take the result of actionflow processing to the front-end page, you need to configure the output parameter.
