I have 1:m relationship tables in my PostgreSql. I like to show the main table attributes as well as the relational table attributes (like grid rows) in QGIS attribute-edit-form.
What are the entries i have to add to dd_* tables to get this?
Answer
Starting in QGIS 2.2 (still in development) there will be a new feature that will allow to manage 1:n relations in a very fancy way.
When you open a feature form with a relation, you will the feature attributes and the related atributes connected to it. In the following example the table "reaches" as a 1:n relation to a table "maintenances".
For more information of how will it work take a look into this blog post from Matthias kuhn.
