Save Photo Gallery for a Record

[SeanHenderson]

Hi,

I have a CDS entity (call it entityMain) and I want to be able to collect a gallery of pictures for it. So I created a new entity (call it entityPictures) for storing the pictures and made a Lookup field to the entityMain.

I have a Gallery (galleryMain) in my app that points to entityMain and a basic 3 screen navigation. I want to be able to select a record in the gallery and from that record's edit screen, add a gallery of pictures to the record.

So I put a camera in the edit screen, set the OnSelect to: Collect(colPix, Camera1.Photo)

Then I added a gallery to the selected record that had Items: galleryMain.Selected.entityPictures

My thinking was that I would add a button that saves the collection to entityPictures, but I need it to apply the proper Lookup value for the record. 

Something like:

ForAll(colPix, Patch(entityPictures, Defaults(entityPictures), {Pictures: Url, entityLookupColumn: galleryMain.Selected}))

But this doesn't result in my picture gallery showing up for the record I have selected. 

Any ideas?

Hi @SeanHenderson ,

I've made a similar test but my pictures updated successfully.

Here's my test for your reference:

1)my collection:

 2)my update formula:

ForAll(colPix,Patch(testmanies,Defaults(testmanies),{testone:Gallery2.Selected,penimage:pic}))

 3)my field setting:

Please note that you need to have the full permission of the Note entity. Because all the images will be stored in this entity.

If you do not have the full permission of the Note entity, you can not update successfully.

Best regards,

Okay, I checked the data in CDS and it actually is saving properly. I guess the issue I'm having is displaying that collection of pictures in a gallery.

So if a user navigates to the details screen for a particular record, on that screen is a button that navigates to the gallery of photos associated with that particular record. So on this new gallery screen, I have a gallery with entityPictures as the data source. But how do I set it up to display the pictures associated to the record that was selected in galleryMain?

I thought it was something like:

galleryPictures.Items: Filter(entityPictures, entityMain.entityMainGUID=galleryMain.Selected.entityMainGUID) but this isn't working.
