Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
PLease, how to make a one2many field required at least one element in openerp.
'coefficient_ids' : fields.one2many('schoolem.coefficient','cours_id','Coefficients',required=True),
You can add method similar like this (example in idea module):
def _check_name(self,cr,uid,ids): for idea in self.browse(cr, uid, ids): if 'spam' in idea.name: return False # Can't create ideas with spam! return True
...but instead would check the coefficient_ids field that something was passed.
Then add to constraints (for validation):
_constraints = [(_check_name, 'Please avoid spam in ideas !', ['name'])]
This would be validation for other field types, I'm not exactly sure for one2many or many2one validation. I believe this maybe possible only for many2one.
