Question

I have 3 fields

 Pick_no= fields.many2one(stock.picking)
Partner_id= field.char
Location_id=field.char

I want to auto fill partner and location fields based on the selected pick_id. What should I use onchange or depends?

Answer 1

IMO You may use onchange() method.

Need to change field datatype. Go to stock.picking model and verify datatype. In your case, you declared with char. It is not wrong but not advisable. If you want to keep char then assign char value, not ID.

partner_id = fields.Many2one(res.partner)
location_id = fields.Many2one(stock.location)
