CHECK constraints from the database can specify accepted lists of values or numeric ranges. They can be represented in QGIS as value map or range widgets, respectively.

The configuration of the form (Relational value) does not work if a foreign table is used several times in the same table. A single field in the correct configuration.

For example :
MyTable

• att1 : Id
• att2 : UserForWork1 -> FK Name : rel1 ; FK table : MyTableOfValues ; FK Field : key
• att3 : UserForWork2 -> FK Name : rel2 ; FK table : MyTableOfValues ; FK Field : key
• att4 : UserForWork3 -> FK Name : rel3 ; FK table : MyTableOfValues ; FK Field : key

MyTableOfValues (list of users)

• key
• value

Thanks

Hi,
This plugin is a great idea. I installed it but get this message when I try to run it.

2017-02-10T08:23:40 1 Traceback (most recent call last):
File "C:/Users/xxxxxxxxx/.qgis2/python/plugins\AutoForm\autoform.py", line 62, in handleFormofLayer

QMessageBox.warning(self.iface.mainWindow(), "Connection Error", "Failed to connect to database. Please make sure that your connection information is correct.")
AttributeError: Connector instance has no attribute 'iface'

Any ideas of what this means and why it may be happening?

I am seeking assistance to kindly update the AutoForm plugin to QGIS 3.6.
Thanks
