Patch Image to CDS

Hey all,

I had a Patch that suddenly stopped working. Basically it was an image field in CDS that had a Lookup to a main entity, so the main entity had a gallery of related photos that were taken with a camera control.

The images were stored using a button that saves the collection using the formula:

ForAll(colPhotos, Patch('Equipment Pictures', Defaults('Equipment Pictures'), {cr387_equipmentphoto: Url, 'Accident Report': galleryMain.Selected, Equipment: dropPickEquipmentEdit.Selected})); Clear(colPhotos); Navigate(scrPhotoView, ScreenTransition.None)

Url is the image in the colPhotos collection that the camera control populates. But now it says "The type of this argument 'cr387_equipmentphoto' does not match the expected type 'Record'. Found type 'image'.

So suddenly it is reading the image field in CDS as Record type.

Any ideas why this broke?

Hi @SeanHenderson

I dont think the url is working to save image data into the CDS. I was able to do this in my old apps with this formula:

ForAll(CameraCollection, Patch('CDSMedia', Defaults('CDSMedia'),{ImageData: Media});

While in my CameraCollection formula:

Collect(CameraCollection, {Media:Camera1.Photo});

Feel free to adjust the formula based on your needs, and see if this helps.

Ok, I was facing the same problem, but seem to have found the solution:
As Powerapps states you need a record to patch the CDS entity. My Patch statement now looks like this and it works like a charm:

ForAll(objPixCentral, Patch(objectPictures,Defaults(objectPictures),{img_Object:{Full:picObj,Value:Pic} }))

To have it look more like a template:
ForAll([yourCollection],Patch([your entity],Defaults([yourentity]),{[your image field in the entity]:{Full:[your camera.photo value], Value:[your camera.stream value]}}))

EDIT:
turns out it is sufficient ot put the same value in both columns within the patch statement, no need to put in the camera.photo and the camre.stream

Actually it is totally sufficient to only determine the "Value" property, leaving out the "Full" property.
To summarize this solution I'd put things so:
when CREATING a record with image patching - use {Value:[your image.image]}
when UPDATING a record with image patching - use {Value:[your image.image]}
when DELETING a record with image patching - use {Value: Blank() , Full: Blank()}

"ForAll([yourCollection],Patch([your entity],Defaults([yourentity]),{[your image field in the entity]:{Full:[your camera.photo value], Value:[your camera.stream value]}}))"

What is yourCollection - is that a table? If so, can I have a gallery.selected instead? Or is that somewhere else?

Hey shavora,
The collection in my case was a normal PowerApps collection, so yes a table of sorts. The gallery is just the "display form" of your collection. You could go for a gallery.selected.[yourImage.image] and patch that to your table as pointed out by @Avinoam . I assume though, that when having a table/collection with the images, it might be a bit of a hassle to individually select the images and patch those, hence the ForAll.

Hey Avinoam,
thanks for the update. When I tried it back then, PowerApps always told me that a value was missing, if I didn't provide values for Value and Full.
