Hey i just added a new element in context with the following code ``` @classmethod def _get_preferences(cls, user, context_only=False): res = super(User, cls)._get_preferences(user, context_only=context_only) if user.employee: res['party_id'] = user.employee.party.id print(res) return res ``` the party\_id is added to the dictionary but when i want to fetch the party\_id using domain `[['party.id','=',Eval('context').get('party_id')]]` this doesnt seems to work not sure what i am doing wrong here any help is greatly appreciated ---

So I guess you are trying to write a record rule. You can not use the context for record rule because it is not safe. Any user can fill the context with any value. If you need a specific value available in the evaluation context of record rule, you must override `Rule._get_context`. ---

``` class Rule(metaclass=PoolMeta): __name__ = 'ir.rule' @classmethod def _get_context(cls): pool = Pool() User = pool.get('res.user') Party = pool.get('party.party') context = super()._get_context() with Transaction().set_user(0): user = User(Transaction().user) if user.employee: context['party_id'] = EvalEnvironment( Party(user.employee.party.id), Party) return context ``` i wrote this code but still no luck am i doing something wrong ? an example would be greatly appreciated ---

So your rule should be written as: `[('party.id', '=', Eval('party_id', {}).get('id'))]` _PS: It is strange to suffix an instance name with `_id`_ ---
