I think I also got confused by the 3 “user” tables (notion import, fibery users, gitlab members).
Here is my updated configuration:
- Gitlab Member (std integration) has 4 relations to MRs and one to User
This works well on the Gitlab Member page or to create reports
- User has a 1 to 1 relation with Gitlab Member
This is not enough to create a board in the Gitlab Member page, showing MRs filtered by Gitlab Member.
If I add a lookup from User to MR (through Gitlab Member), I can see the MRs on the User page, but still cannot filter the board (as you explained above)
Note I would prefer here to see those as a board or list, not only as fields.
To be continued after next meeting, sorry
