Hi, 

when I press smart button the function that returns orders already created does not run

anyone knows why?

class ContractContract(models.Model):

    _inherit = 'contract.contract'

    orders_count = fields.Integer(compute="_compute_orders_count")

    orders_ids = fields.One2many(string='Orders', comodel_name='sale.order',     inverse_name='contract_id', default=None)

    def action_view_sales_orders(self):

        return {

            'name': 'Orders',

            'type': 'ir.actions.act_window',

            'res_model': 'sale.order',

            'view_mode': 'tree',

            'domain': [('id', 'in', self.orders_ids.ids)], 

            'context': "{'create': False}"

        }

    <button class="oe_stat_button"

      type="object"

      name="action_view_sales_orders"

      icon="fa-list"

        <field string="Orders"

               name="orders_count"

               widget="statinfo"/>

    </button>
