Hi,

I need to send a value from one form to another form via field to set a default value in a record that I am creating using a many2one field.

Imagine I have 3 models parking_space, driver and car. A driver owns cars and also owns parking spaces. A parking space has one owner and one car (for the sake of this example). 

Now I am in the form of the parking_space and want to create a car using the field of this form. After clicking Create or Edit (in the car field) the car form pops and I want to have the owner field of this car set as the owner of the parking_space. So I guess I need to send the owner of the parking space via the car field using the context attribute but I can't get it working.

I have tried something like this:

<field name="car" context="{'default_owner_name':owner_name}" />

But the owner field in the car form is empty.

I also have tried sending a value via context and having the owner field in the car model with a default attribute that calls a method that checks the context to set the value of the field, something like this:

<field name="car" context="{'owner_id':owner_name.id}" />

owner_name= fields.Many2one('res.partner', 'Driver',required=True, default=_get_default_owner)

@api.model

    def _get_default_owner(self):

        owner = None

        if self.env.context.get('default_owner_id') != False:

            owner_id= self.env.context.get('owner_id')

            owner = self.env['res.partner'].search([('id', '=', owner_id)])

        return owner

But the context has not my custom value. Can someone help me?

Thank you!
