Posted on by TimmyBoy 997

Hello,

how can i patch an variable when already been used with data

I need to update 1 column only in this existing variable, but this gives me an error

Set(checkedEdit; Patch(checkedEdit.ID; {tmp: TextInput3_1.Text}))

The checkedEdit is been created in a gallery when pressing a button

Set(checkedEdit;ThisItem)

 Thank you

    You can't. You must use a collection or some other way.

    Try this:

    Patch the SharePoint List:
    Update the SharePoint list with the new 'tmp' value and any other necessary changes.

     

    Patch(yourSharePointList, {ID:ThisItem.ID,tmp: TextInput3_1.Text})

     

    Refresh the SharePoint List:
    After patching the SharePoint list, you might need to refresh the data to ensure it's up-to-date in the app.

     

    Refresh(yourSharePointList)

     

     

    See if it works with neither variable nor collection

    See if it helps @TimmyBoy

    Hi @TimmyBoy 

    I think you might have just made a mistake in your call to Patch - there's no need to specify .ID in the item to patch. If you try the following, does it work?

    Set(checkedEdit; Patch(checkedEdit; {tmp: TextInput3_1.Text}))

    hi @timl 

    No, its gives me this error

    the second argument to the 'index' function must be between 1 and 1.
the lower and upper limits of the table.
The upper limit can be lowered due to the non-transfer limit.

     Even no idea what it means 😞

    Hi @timl ,

    My apologies

     

    //patch
Set(varNewImage; Blank());;
If(!IsBlank(TextInput3_1.Text);
 Set(varUpdatingPhoto; true);;
 // Patch
 Patch(
 myData;
 LookUp(myData; 'Id (ID)' = checkedEdit.ID);
 { tmp: TextInput3_1.Text }
 );;
 Patch(
 colMyData;
 LookUp(colMyData; ID = checkedEdit.ID);
 { tmp: TextInput3_1.Text }
 );
 // Reset
 Set(varNewImage; Blank());;
 Set(varUpdatingPhoto; false);;
 Set(varError; "");;Set(checkedEdit; Patch(checkedEdit; {tmp: TextInput3_1.Text}))
 ;
 Reset(TextInput3_1);;
 Set(varError; "Error: tmp is blank.")
);;
Set(varOkBox; false);;
Set(varItem; Blank())

     

    It seems there's a error in my own code
    And not yours.
    Even i have no idea what line cause this error

    Hi @TimmyBoy 

    This is not a error that I've seen before. What data source are you using? Is it Dataverse?

    If you just try to do a Patch agaisnst the data source, do you get the same error?

     Patch(
 myData;
 LookUp(myData; 'Id (ID)' = checkedEdit.ID);
 { tmp: TextInput3_1.Text }
 )

    If not, I would attempt to run each part of the code in isolation to determine the line that's causing the error.

    It might also be useful if you screenshot and post the error.

    Hi @timl 

    I use SharePoint list

    And nope the patch works fine,

    I will look into it as you suggested
    to go over each line
    I will be back, if this has been solved at mine side 😉
    If not i will make a screenshot 😄

     

    Thank you

    @timl 

    Okay, seems the error comes only when i patch the collection

     Patch(
 mycollection;
 LookUp(mycollection; 'Id (ID)' = checkedEdit.ID);
 { tmp: TextInput3_1.Text }
 )

    Patch into the SharePoint list it works well
    So why does the error comes on the collection?
    Any ideas...
    Thanks

    @timl  & @poweractivate 

    Got it solved

    Seems i only need

    Set(checkedEdit; Patch(checkedEdit; {tmp: TextInput3_1.Text}))

    This line to update the column, this gives no error 😊

    Thank you both for the awesome support 🤗
