Construct a "domain=" across many2many fields

If you too hate the display of this forum, please refer:

domain = ('foofield', 'operator', barvalue)

  • In my case barvalue IS a list.
  • I want foofield to be a list. More specifically, I want foofield to contain the values (as a list) of the many2many field 'foofield'
  • I want operator do define foofield as an entire subset of barvalue. (best guess: 'in')

I know this is probably not possible, so workaround, conceptual help would be nice...

The domain you wrote should simply work because the [(field, operator, value)] in your case is [] in [] and for many2many fields, this should suffice.

Do you face any errors, warnings?

Actually, https://github.com/odoo/odoo/blob/1f20f61ab4f6acf79f4db6ba9a17c1282014ef5f/openerp/osv/expression.py#L932-L971 supports your answer very well.

Errors might raise from different sources while debugging. I somehow was prone to believe this doesn't work because documentation (https://doc.openerp.com/v6.0/developer/2_5_Objects_Fields_Methods/methods.html/) states: 

field_name must be a valid name of field of the object model, possibly following many-to-one relationships using dot-notation, e.g 'street' or 'partner_id.country' are valid values


(explicitely states many2one but doesn't mention many2many )
