Attempt to Update just the file location

[eduardoagr]

I have a child Notes, and I want to update just the file location

`public async void UpdateNotebookNote(string Id, string FileLocation) {

        await firebaseClient
            .Child(AppConstant.Notes)
            .Child(Id)
            .PatchAsync(FileLocation);
    }`

but when I do this, I get this exception

`public async void UpdateNotebookNote(string Id, string FileLocation) {

        await firebaseClient
            .Child(AppConstant.Notes)
            .Child(Id)
            .PatchAsync(FileLocation);
    }`

You didn't include the exception (looks like a copy/paste mistake). And you didn't include any details about your db structure (e.g. what properties the Note object has).

Sorry @cabauman

this is mt database structure

"Notebooks" : { "-MxdwMGbOdhmL85JoX9K" : { "Color" : "#FF008000", "CreatedDate" : "Tuesday, March 8, 2022", "Name" : "NOTEBOOK", "UserID" : "4B7L4mRordT2s373NCwgNLesxj13" } }, "Notes" : { "-MxepAH9BW0Uv065a5LR" : { "FileLocation" : "", "Name" : "ed", "NotebookId" : "-MxdwMGbOdhmL85JoX9K" } } }

this is how I am trying to update

` await firebaseClient .Child(AppConstant.Notes) .Child(Id) .PatchAsync(FileLocation); }``

Exception

Firebase.Database.FirebaseException: 'Exception occured while processing the request.

One more question.

.PatchAsync(FileLocation);

Is FileLocation a string?

[eduardoagr]

@cabauman yes it is

[cabauman]

Patch needs an object:

.PatchAsync($"{{ \"FileLocation\" : \"{FileLocation}\" }}");

[eduardoagr]

why do I have to put \

[cabauman]

It's json so we have to escape the quotes. I hope it helped.

[eduardoagr]

yes thank you @cabauman
