Hi Umashankar,
you can not limit the many2many field directly.The way you can limit that make your many2many field as many2one and make it as many2many using widget="many2many" and you can set the limit.for example
<group>
<field name="partner_id" options="{'limit': 10, 'create': false, 'create_edit': false}" widget="many2many">
<tree>
<field name="your_field1"/>
<field name="your_field2"/>
</tree>
</field>
</group>
Hello Umashankar,
I think this code very helpful for you and this code is fully dynamic.
Here i give one simple example.
in .py file
'limit':fields.integer('Limit'),
'field_ids': fields.many2many('other.object.name', 'relation object', 'actual.object.id', 'other.object.id', string='Name'),
def _check_limit(self, cr, uid, ids, context=None):
new_list = []
for obj in self.browse(cr, uid, ids, context=context):
if obj.limit <= 0:
return False
for field in obj.field_ids:
new_list.append(field.id)
if obj.limit < len(new_list):
return False
return True
_constraints = [
(_check_limit, 'Please check your limit !', ['limit','field_ids']),
]
if you find this answer helpful, please give me a thumbs up vote
Thanks & Regards,
