Make Function fields work with not ModelSQL xxx2Many
Currenly One2Many and Many2Many Function fields must return a list of ids to
select the records. It will be great to return a list of dictionaries which
contains the values for the fields of each record. This will allow to fetch
records with:
instances = [(Model(*values) for values in vlist)]
Where vlist is a list of dictionaries.
This can be used to fill not ModelSQL models (only ModelView) to allow to
display a list of computed data.
