How to best generate seed data for a data store when a new entity is created?

(0) ShareShare
ReportReport
Posted on by CU28102214-0 2
Hey,
 
I have a project where users will create a new entity in a Canvas Power apps.
 
As soon as they click create on the new entity I'd like to populate other entities with 'seed' data to support the underlying functionality of the system. Ideally a user would be able to customise this 'seed' data and then the system would understand when the entity is being created what customised seed data to insert.
 
To give an example, lets say I had a ecommerce Canvas Power app.  I allowed the users to create a store.  Each store has a list of supported currencies.  When they create the store I want to insert the supported currencies from their default configuration.  There are also 4 or 5 other entities which I'd like to insert their default store values into from their custom configuration customise.
 
Any ideas would be appreciated.
 
Thanks,

    1. Create New Entity in Power Apps - Use a form or button to create a new entity.
    Use the Patch function to add a record:
    Set(newEntityID, Patch(Entity, Defaults(Entity), {Field1: Value1, Field2: Value2, ...}).ID)
    Store the new entity ID for further use.
    2. Trigger Power Automate Flow - Add a Power Automate button in Power Apps to trigger a flow
    'FlowName'.Run(newEntityID, User().Email)
    Pass the newEntityID and user email to the flow.
    3. Power Automate Flow Setup - Trigger - Use "PowerApps" trigger to start the flow.
    Use "Get Rows" (Dataverse) to fetch user-specific default configurations.
    Filter('DefaultConfigurations', UserID eq UserEmail && EntityType eq 'Store')
    For Insert Seed Data ,  Use "Create a new row" actions for each related entity:
    Add row to table: 'Currencies', StoreID = newEntityID, CurrencyCode = config.CurrencyCode
    4. Customize Seed Data in Power Apps - Create a screen to manage seed configurations.
    Use LookUp to display user-specific configurations:
    LookUp('DefaultConfigurations', UserID = User().Email && EntityType = "Store")
    Use the Patch function to update configurations:
    Patch('DefaultConfigurations', LookUp('DefaultConfigurations', ID = selectedConfigID), {Field: NewValue})
    5. Use IfError to handle errors during entity creation.
    IfError(Patch(Entity, ...), Notify("Error creating entity", NotificationType.Error))
    6. Deploy as Solution - Bundle Power Apps, Power Automate flow, and entities in a Power Platform solution
