I've extended the 'account.analytic.account' model with a One2many field that references a second model with a One2many field.
When I try to iterate through the second One2many field from the compute method it only lists records that have just been added. Previous records (which are visible on the interface) are not visible in code using the 'self' context until the parent record is saved.
example:
for line in self.One2manyField: #only gets here for records I add during current session, or all records if parent is saved #how can I see previously saved records?
Here is the code:
1.) extended 'account.analytic.account' model
class account_analytic_account(models.Model): _inherit = ['account.analytic.account'] service_location_ids = fields.One2many(comodel_name='contract.service.location', inverse_name='contract_id', copy=True)
2.) First referenced One2many model:
class Contract_Service_Location(models.Model): _name = 'contract.service.location' _description = 'Service Location Record' #problem is here! #compute method for subtotal field @api.one @api.depends('recurring_line_ids','recurring_line_ids.price_subtotal') def _compute_subtotal(self): total = 0.0 #I tried to get previously saved ids, but returns nothing, until parent record is saved old_ids = self.env['contract.recurring.line'].search([('service_location_id', '=', self.id)]) #this only works for new entries during same session, or until parent record is saved. Why? for line in self.recurring_line_ids: total = total + line.price_subtotal #set field self.price_subtotal = total contract_id = fields.Many2one(comodel_name='account.analytic.account') fiscal_position = fields.Many2one(comodel_name='account.fiscal.position', string='Default Taxes') partner_id = fields.Many2one(comodel_name='res.partner', string='Service Location', help='Optional seperate billing address from customer AND service locations',required=True) sequence = fields.Integer(string='Sequence', help="Gives the sequence order when displaying a list of sales order lines.") price_subtotal = fields.Float(compute='_compute_subtotal', string='Subtotal', digits_compute= dp.get_precision('Account'), readonly=True, store=True) pricelist_id = fields.Many2one(comodel_name='product.pricelist', string='Pricelist', required=True, help="Pricelist for current customer.", default=_get_default_pricelist) recurring_line_ids = fields.One2many(comodel_name='contract.recurring.line', inverse_name='service_location_id', copy=True)
3.) Second referenced One2many model:
class Contract_Recurring_Line(models.Model): _name = 'contract.recurring.line' _description = 'Recurring Service Location Line' @api.one @api.depends('price_unit', 'discount', 'product_uom_qty','product_uos_qty', 'product_id', 'service_location_id.partner_id','service_location_id.pricelist_id') def _compute_subtotal(self): price = self.price_unit * (1 - (self.discount or 0.0) / 100.0) taxes = self.tax_id.compute_all(price, self.product_uom_qty, product=self.product_id, partner=self.service_location_id.partner_id) self.price_subtotal = taxes['total'] if self.service_location_id: self.price_subtotal = self.service_location_id.pricelist_id.currency_id.round(self.price_subtotal) service_location_id = fields.Many2one(comodel_name='contract.service.location', required=True, ondelete='cascade', select=True) name = fields.Text('Description', required=True) product_id = fields.Many2one('product.product', 'Product', domain=[('sale_ok', '=', True)], change_default=True, ondelete='restrict') price_unit = fields.Float('Unit Price', required=True, digits_compute= dp.get_precision('Product Price')) price_subtotal = fields.Float(compute='_compute_subtotal', string='Subtotal',store=True, readonly=True, digits_compute= dp.get_precision('Account')) product_uom_qty = fields.Float('Quantity', default=float(1), digits_compute= dp.get_precision('Product UoS')) discount = fields.Float('Discount (%)', digits_compute= dp.get_precision('Discount'))
