Hello there fine community. I have already made similar App and had no issue with this part but only today…
I have a collection that has as source a rellation collum. But the data that is on this relation collum do not shows on the collection component. Can somebody tell me why??
I have alresdy done it exactly the same way and had no problem before! Thank you.
Can you provide screenshots of your configurations please ?
Do you have row owner applied to the table that the relation is pointing to?
I can see two issues with your screen shots.
- Firstly, the first row in your table appears to be empty. This means that your relation is possibly only matching empty rows in the target table. This may explain why you see nothing when you use the relation as the source of a collection. Fixing it might be as simple as just deleting that first row. If it doesn’t, please share a screen shot of your relation column configuration.
- Secondly, you have a RowID column, but it is empty. This indicates that it is not behaving as a true RowID column. I’m guessing that you attached the sheet and it already had that column in it? In that case, Glide wouldn’t detect it as a RowID column and if you need a RowID then you’d have to add another one.
PS. Jeff asked about Row Owners, not RowID. They are two different things.

Hello Darren. Great tip,…you were right! I did attached the sheet and it was already there. I rearrenged the google sheet that powers it and added another Row ID and it works. Thank you a lot!!
