The For Each action is a loop structure that performs specified operations for each item in a list or collection, respectively. It is especially useful for processing data from different databases and performing specific operations based on user interactions.
Example Scenario 1: Performing an Action on a User List
First, you need to define the list of users to process. For example, you can create a list called “Users Who Need to be Disabled”.
Processing Users with For Each Action
- Add For Each action:
- UI Design → Properties Panel → +ADD ACTION → Initial Actions → Condition → For Each
- Select List:
- Link the list of users to be processed to the For Each action.
- Run DisableUser Action:
- You can disable users by running the DisableUser action for each user respectively.
Example Scenario 2: Update User's Balance
Let's see how you can use the For Each action to update a user's balance.
Scenario:
- The user has a Balance value.
- The price of each product on the Products List that the user wants to buy should be updated by deducting the price of each product from the balance.
Steps:
- Add For Each Action:
- Link the list of products that the user wants to buy to the For Each action.
- Use Current:
- Access each item in the loop through “Current” and get the Count and Price of each product.
- Update Balance:
- Update the user's Balance value by deducting the price of the related product.
List Usage with For Each Action
- The For Each action is not used to create a list in Kuika, but to run actions sequentially for each item in an existing list.
- This action should be used to perform sequential actions on the data to be processed, rather than creating a dynamic list.
