Re-create dynamically a collection (using a custom API and not knowing the structure in advance)

(0) ShareShare

Posted on by 19

Hi,

I'm building an app where I request for a set of data using a custom API (TestConnection).
I successfully get back data and assign them to collections without knowing the structure in advance.

But is it possible to create dynamically a collection that has the same structure? I can have the same result if I know the structure in advance (I just create the same fields inside a ClearCollect, as the structure of swagger) but what are the chances to get it automatically?


From DataBase

ClearCollect(CollLine, TestConnection.CollLineGetAllCollLines())

Manually:

Collect(CollLine, {Name: LDescriptionInput_2.Text, WorkType: WTDropdown1.Selected.WorkType, StartTime: StartTimeInput_2.Text, EndTime: EndTimeInput_2.Text, TotalTimeH :hours, TotalTimeM : minutes, Project: ProjectDropdown_2.Selected.PName, DayField: DayFieldDropdown_2.Selected.MyDay, WeekField: WeekFieldDropdown_2.Selected.WRName, Comments:NotesTextInput.Text }); UpdateContext({showDialog:true}); UpdateContext({hourflag: ETDropdown.Selected.h, minflag:ETDropdown_.Selected.m});

    Hi @v-micsh-msft,

     

    Right. By saying dynamically, I meant to get the Collection structure without the data from the Custom API in order to use the same method for many cases & structures and not have to write the fields one by one.

    It's a pitty that we cannot have it but any case, we can write the function, is not really a big deal.

     

    Thank you very much for your response.

     

    Best,

    Christina

    Hi @christinadot,

     

    I am a little confused about "Re-create dynamically a collection" here.

    If you use Custom API, the data structure should have been defined already within the swagger.

    And the "From Database" formula you used here should be the right formula to create the collection.

     

    By saying dynamically, do you mean to get the Collection structure without the data from the Custom API?

    Based on what I know, there is no available ways.

    Please post back if I have anything misunderstood.
