Bug report #16446

Updated by Giovanni Manghi over 4 years ago


I can't make N:M relation working.

In attachment you'll find a small SQL script to create simple tables with restrictions as described here : https://github.com/qgis/QGIS/pull/2522

and a small QGIS project.

There are two issues :

When I create an observation, I can't create an author (auteur) linked to it

When I create an observation, I can't make a relation to an existing author (auteur). There is an error message because the new observation's id is not inserted in the relation table but a null value is inserted which violates not-null constraint.
