Hello PA Community,
I have an app that has two AddMediaWithImage controls and when selecting the Submit button trigger the patch which write those images to Blob Storage and their metadata to the same record in SQL Server.
The new record can be edited in the app and each image can be changed individually from the form, with the changes sent in one patch, which in turn would delete its existing image in blob storage, write the new image to blob storage and then update the existing SQL record with the new meta data from the new images in blob storage.
The issue I've been having is on the edit side of the equation. I can edit each image individually and patch the individual change without issue, but if I change both images and then patch, Image1 is fine, the old Image2 gets deleted in blob storage, but new Image 2 does not get written in blob storage, so new Image 2 meta data does not get updated in SQL server creating an error message on read.
If I reverse the code in my patch, putting Image 2 code before Image 1 code, the exact reverse happens, and Image 2 gets updated, but Image 1 does not.
Below is a copy of my code, I welcome any feedback you may have on resolving this issue of editing both Image under a single patch to blob storage and SQL server:
//Edit Record-SQL
If(
Form1.Mode = FormMode.Edit,
Patch(
TestBlobStorage,
LookUp(TestBlobStorage, ID = Gallery1.Selected.ID),
{
Test_Field:DataCardValue3.Text
}
)
);
//Edit Record-Image 1
If(
Form1.Mode=FormMode.Edit,
Set(varBlobID1, LookUp(TestBlobStorage, ID = Gallery1.Selected.ID, ImageAzureFileID1))
);
If(
Form1.Mode=FormMode.Edit And Not(IsBlank(AddMediaButton1.Media)),
AzureBlobStorage.DeleteFileV2("xxxxxxx", varBlobID1)
);
If(
Form1.Mode<>FormMode.View And Not(IsBlank(AddMediaButton1.Media)),
Set(varImage1FileName, Concatenate("TestImage", "-", Text(Now(), "yyyymmdd-HHmmss"), "-", AddMediaButton1.FileName))
);
If(
Form1.Mode<>FormMode.View And Not(IsBlank(AddMediaButton1.Media)),
Set(varAzureImage1, AzureBlobStorage.CreateFileV2("xxxxxxx", "xxxxxxx", varImage1FileName, AddMediaButton1.Media))
