Hi

I have two models:

class Pharmacy(models.Model):
    _inherit = 'res.partner'
     medicine_ids = fields.Many2many('product.template', string="Existing Medicines") 


class Medicine(models.Model):
    _inherit = 'product.template'
    pharmacy_ids = fields.Many2many('res.partner', string="Pharmacieis")

def add_pharmacies(self):

some logic

I need in form view of Medicine by pushing a button the function add_pharmacies be called and 1 pharmacy be added to the list of the pharmacies that have that product and the product to be added to specific pharmacy.

What Should I write in my function?

To your goal you should apply the special operators configured for many2many fields. In this case it is 'add': [(4, ID)]. The example to add a new pharmacy to the field 'pharmacy_ids':

@api.multi
def add_pharmacies(self):
    for record in self:
        id_to_add = 1 # put here your logic of how this pharmacy should be added
        record.pharmacy_ids = [(4, id_to_add)]

I want to populate Customer/Vendor Many2one field based on Selection Field which has two selection 1.Sale Order, 2.Purchase Order. If it is Sale Order then Many2one field should have Customers from sale.order model and if it is Purchase Order then Many2one field should have Vendors from purchase.order model. v:odoo12 Resuelto
