Hi Patrick,
I did part of what you listed in my Plugin DataDrivenInputMask (Python),
only available for PostGIS, though. Source code and documentation are on
github.
The plugin provides suitable widgets for any supported data type (e.g.
date, boolean, arrays types). You might also want to look at how NULL
values are handled (if field has no NOT NULL constraint). Furthermore
any relation type (1:1, 1:n, n:1 and n:m) is supported.

Hi,
We (titellus and camptocamp) are going to start working on adding a few
functionalities needed for INSPIRE to QGIS core. Before starting, we’d
like to tell the community what we plan to do (maybe, some are optional)
and give a chance to everybody to comment.
-
Advanced attribute types support
-
Add support for viewing/editing maps (key/value) and arrays
-
Usage of native type for postgis
-
Usage of string representation for sqlite (for example JSON)
-
Add a few expression functions for accessing those types:
array_get(idx), array_length, array_join(separator) / dict_get(key), etc
-
Add a few function to search in those types: array_search(),
dict_search()
-
Detect a date column and use the proper widget for editing those
-
Same for other types
-
Allow plugins to provide custom widgets for specific types
automatically.
-
Fix bug where null dates are shown as the current time instead of null
in forms and saved like that, even for features that are not modified
-
Custom types widgets, per type
-
Auto discover database joins:
-
Add FK (Foreign Key) discovery to the postgis and spatialite specific
code.
-
Improve QGIS when creating relations according to the FK in the DB:
view existing relations in the DB and select those to add
automatically to
the project.
-
Improve QGIS when creating joins in layers according to the FK in the
DB: view existing relations with the current layer and select
those to add
automatically.
If somebody is already working on one of those features or is having
recommendations/comments/questions, please tell us.
Is there any point that would require a QEP?
Thanks
