Hi Luca,
Since two months, it does support custom ui form [0]
You have to place a widget in your form and a dynamic property to the
widget.
You call it qgisRelation and set it to the id of the relation.
Cheers,
Denis

Hi denis,
thanks a lot for the tip,I'll try it immediately.
I know the brand new "1 to many" feature present in qgis 2.1 and it's
gorgeous, but as I know it works only with autogenerate forms, but I
need to use a custom forn because I have some code into it.
many thanks
Luca

Hi Luca,
The best way to do this, is to set your personnally designed UI
file in the layer properties->field properties->attribute editor
layout->provide ui file
Then, you want to call qgis method to show a feature form:
http://qgis.org/api/classQgisInterface.html#aff2467aa3cefd8fc5b59213f385b7180
And you would need some processing to show it:
1. get feature id from the selected line
2. fetch the feature of the main layer
3. get the foreign key from one of its fields
4. fetch the corresponding feature
4. show the feature form with it
Anyway, if I understand properly, you're trying to do something
which has been recently added to QGIS (it's in the master
version), it's 1:n relations.

Hi to all,
I need a help from a python guru. I'm trying to move my first
steps with pyqgis.
I've got two qgis layer with a 1 to many relation. I create a
custom form for the parent layer with a QTableWidget that contain
the primary key of the child layer. Now I want to open another
custom form with the data of the child record selected into
the QTableWidget. I try to look up into the QGIS API
Documentation but I'didn't find the solution to my problem.
Now I just can open form with this code, connected with a button:
path = os.path.dirname( os.path.abspath( __file__ ) )
uifile = os.path.join(path , my_form.ui')
window = uic.loadUi(uifile)
window.exec_()
how can I connect my form with the right data ?
Can I use some method to select the right layer/record and open
it in the form ?
Thanks in advance for any tips
Luca
