[IMP] core: read_group: allow grouping by non-stored related fields
Here we are jumping between fields to make joins and finally reach the table where field is stored, so we can read it.
There are two types of virtual fields (virtual in a sense, that they are stored not in a current table, but in another one):
1. inherited fields or implicit related fields
2. explicit related fields
Any inherited field could be represented as an explicit related field. For example, inherited field "name" in res.users is equivalent to following explicit definition:
name = fields.Char(related='partner_id.name')
Things become more complicated when we have related fields inside related fields (have you seen Inception 2010 movie?). Let's see following example:
class Partner(models.Model)
_name = 'res.partner'
parent_id = fields.Many2one('res.partner', string='Related Company', index=True)
parent_name = fields.Char(related='parent_id.name', readonly=True, string='Parent name')
# ...
class User(models.Model)
_name = 'res.users'
_inherits = {'res.partner': 'partner_id'}
partner_id = fields.Many2one('res.partner')
# ...
class Guru(models.Model)
_name = 'res.guru'
_inherits = {'res.users': 'user_id'}
user_id = fields.Many2one('res.users')
# ...
class Task(models.Model)
_inherit = 'project.task'
guru_id = fields.Many2one('res.guru')
guru_parent_name = fields.Char(related='guru_id.partner_id.parent_name')
# ...
To read guru_parent_name we do for-loop over ['guru_id', 'partner_id', 'parent_name'] and expand field if it's related:
['guru_id', 'partner_id', 'parent_name']
['guru_id', ['user_id', 'partner_id'], 'parent_name']
['guru_id', ['user_id', 'partner_id'], ['parent_id', 'name']]
Because any field in the expanded chain may be related field, we should do this process recursively. This is how function "process" works.
For more examples of possible variants of related fields check tests defined in
./addons/test_read_group/tests/test_related.py
def process(model, alias, field, sudo):
if not field.related or field.store:
return model, alias, field, sudo
