Update SharePoint item from PowerApps Collection

(0) Share

Report

Posted on by Community Power Pla... Microsoft Employee

I am attempting to add attachments to my SharePoint list (test New Triage Request Form) to a specific record. I have two screens which have an Edit Form (Form_1, Form_2). Both attachments appear in my collections (TempAttachmentsCol); however, when I run the following Patch, only the Form_2 attachment appears on the SharePoint.

Patch('test New Triage Request Form', LookUp('test New Triage Request Form',ID=TempCol.ID),{
},Form_1.Updates,Form_2.Updates);

Is there a better way to update the SharePoint record with the attachments in the Collection? Or am I on the right track? Thank you

Hi @Anonymous ,

Firstly FormName.Updates requires the attachments to be in an attachment control (not sure what you mean with attachments in the collection.)

I assume you have an attachment control on each - the problem you have (I did some testing here to confirm this) is that like any field, when Power Apps updates it, the field is overwritten by the current content of the field in the form providing the update.

In this case, Form_2 would contain any existing (written to the list at the time it was opened) attachments and the new items uploaded to it. It knows nothing about anything you have just done on Form_1, so updates the field with those items and subsequently over-writes anything just changed by Form_1 (this is not just the attachments, but any other common field they contain)

It is also not much use refreshing Form_2 after submitting Form_1, as this would clear any updated information on it. Your only solution is to submit Form_1 first, then open Form_2 after this and then change and submit it.

Hi @Anonymous ,

Before you spend time exploring @RezaDorrani 's video, it relates to a completely different subject and far more complex process to what you have posted (and actually involves only one Attachment control). You have asked about sequentially Patching two unsaved forms, both with attachment controls. The easiest solution is what I posted - save Form_1 first and then open Form 2.

Hi @Anonymous ,

The last video only has one of each one attachment control and does not solve your problem. The whole idea of multiple forms is to have different fields on each of them, so when you Patch(Form.Updates), nothing will overwrite something written earlier. You can however use Patch with individual field references on everything but attachments.

The best way to test it download the demo app supplied in the demo by PowerApps guru @RezaDorrani and see it yourself. Rather than confusing information

@Anonymous ,

I will not continue this side conversation on your thread other than ask that you tag me if you want some actual code and factual guidance rather than hyperlinks.

I thank you both for the enthusiastic replies. WarrenBelz was very close to the solution. His comments made me relook at the patch. I created a second patch so each form had it's own and it worked. Also, I have viewed many of RezaDorrani videos. They have been very helpful. I have also gained a lot of knowledge from Shane Young and Audrie Gordon. I thank you all for posting these videos. I hope I can continue to come to this Community for answers.

Thanks @Anonymous ,

Good to see my analysis of your issue was not confusing to you. What you have done is probably what I suggested (to do them separately)
