I would like to automatically cancel the selection of a value in a many2one field when I click for example on the invisible radio button of the interface client: 

model.py file:

........

Product_id = fields.Many2one(‘product.template’)

State = fields.Selection((( ‘H’, ‘Hide’), (‘S’, ‘show’)), string=“state”)

hide_product = fields.Boolean()

@api.onchange

def _cancel_selection(self):

      If ( self.state is ‘H’):

           # cancel selection automatically on product_id field     

           Hide_product = True

           Self.product_id = “ “

............

view.xml file:

..........

< field name=“State” on_change=“1”  />

< field name=“product_id” attrs=“{‘invisible’ : [ (‘hide_product’, ‘=‘, True) ] } “  />

......
