Attribute constraints when editing vector layers

[anonymous]

As I'm introducing QGis in my university department, I was asked if it would be possible ("as in ArcGIS with mdb geodatabase", as they say) to enable a constrain, during digitizing and editing, on vector layers attributes (on Postgresql) when on the attribute field there's a constrain to a list of values that I set in another table. Exscuse me for my horrible english, I hope it's understandable! It would avoid inserting wrong attribute values when needed...

I don't know if it's possible to be implemented in 0.8 (I would prefer, of course!). In case it's tto late 0.9 would be, obviously, ok.

Hi Giovanni,

The feature you mention would be very useful. It would however require major changes in basic components of qgis, so it's impossible to consider it for 0.8.

So what should I do? Do I have to post a new "enhancement" for 0.9, or it will considered anyway leaving this ticket?

Ok, let's set it as enhancement for 0.9 release. Originally I've deleted the milestone as it won't get to 0.8 and it's not clear for what version it will be implemented.

r9092 introduces some enhancements that covers this partly, although not by strict constraints.

This seems to me a reality now with the edit widgets under layer "properties -> attributes". Please reopen if I'm wrong.
