i mean when i click on the authorā€™s name nothing happens.

and the relations that i already added seems to not match on the data editor

23

you might have a problem with structuring data and relationsā€¦ Glide will not warn you if there is a circular dependencyā€¦ they just donā€™t show optionsā€¦ but if redo relations for the element or delete relationsā€¦ that might create a problem when adding new relation that is not defined in previous state of that elemnt

Okay thanks @Uzo and @Jeff_Hager for helping me, iā€™ll try to figure out what the problem is.

25

i know that tracing relations in the advanced app is a painā€¦ but thatā€™s the only way to find a problemā€¦
also, Glide have a glitch that will bring back previous relations when is not stableā€¦ so the best way to fix it, is to delete that problem and redo itā€¦ but make a copy before doing that

The best advice I can give you in case of relations is to name the relation column as full as possible so you know what you were trying to do and in the future will be easy to know what is that forā€¦(even if the column name is way too long) and test it in every possible wayā€¦ and if doesnā€™t work delete it and all associated columns so there is no mess and even when coming back to this app after days or monthsā€¦ you will know what is going onā€¦ also move assisted columns next to that relation column

This happened likely because you were using an action that navigates to a relation instead of a sheet. Can you confirm that this is the case?

Whatā€™s your desired flow?

I think Yes i have an inline list that shows a list of books and when i click on a book it takes me to a details view of every book with the name of the book and the name of the author. i already have an relation that shows all the books related to that author.
What i want to add is when on a book to click on the author name under the book and go to a screen that showā€™s the author photo a brief description and add all the books related to that author as an inline list

there is a simple way to do that ā€¦, show a new screen with a filter from a previous screen data

31

any tutorial on how to do this ?

32

okay Iā€™ll check that

@Uzo i canā€™t find it

35

i do expect your app is an advanced one, and we will be shooting in the dark ā€¦ unfortunately it will take hours for me to dig into your app and find a problemā€¦ there are many experts here who might do that, I canā€™tā€¦ it will affect my pay customers

if is a basic one it should give default resultsā€¦ let me try again with a basic approachā€¦ try to open a new app and see this algorithm behave the same wayā€¦ if notā€¦ it is the relations problem
