从自定义模块 odoo 13 创建发票行

Question

我创建了一个自定义模块并创建了一个按钮来创建发票，发票已成功创建，但问题是发票行 ID 只创建一行而忽略另一行。这是我的代码

    def create_invoice(self):
    invoice = self.env['account.move'].create({
        'type': 'out_invoice',
        'state': 'draft',
        'journal_id': 1,
        'partner_id': self.partner_id.id,
        'amount_untaxed': self.package_price,
        'ref': self.name,
        'invoice_origin': self.name,
        'invoice_line_ids': [(0, 0, self._prepare_invoice_line())]
                           
    })

    return invoice
    
    
def _prepare_invoice_line(self):
    for order in self:
        for line in order.additional_services_ids:
            res = {
                'product_id': line.service_id.id,
                'quantity': line.quantity,
                'name': 'pro',
                'discount': 0,
                'price_unit': line.price_unit,
            }

        return res

Odoo many2many 领域很痛苦。

你的invoice_line_ids

中应该有这种数据结构

[
  (0,0,[invoice_line_1]),
  (0,0, [invoice_line_2]),
  ...
]

所以像这样修改你的代码是可行的：

    def create_invoice(self):
    invoice = self.env['account.move'].create({
        'type': 'out_invoice',
        'state': 'draft',
        'journal_id': 1,
        'partner_id': self.partner_id.id,
        'amount_untaxed': self.package_price,
        'ref': self.name,
        'invoice_origin': self.name,
        'invoice_line_ids': [(0, 0, line) for line in self._prepare_invoice_line()]
                           
    })

    return invoice
    
    
def _prepare_invoice_line(self):
    res = []
    for order in self:
        for line in order.additional_services_ids:
            res.append({
                'product_id': line.service_id.id,
                'quantity': line.quantity,
                'name': 'pro',
                'discount': 0,
                'price_unit': line.price_unit,
            })
    return res

我不知道这是一个错误还是设计的问题，但我已经为此苦苦思索了很多次。

--- 编辑 --- _prepare_invoice_line 方法也有问题。它只返回一行而不是行列表。

要创建多行，只需使用 Odoo one2many 在 data 上执行 loop 创建数据的语法。

示例代码:

def create_invoice(self):
    invoice = self.env['account.move'].create({
        'type': 'out_invoice',
        'state': 'draft',
        'journal_id': 1,
        'partner_id': self.partner_id.id,
        'amount_untaxed': self.package_price,
        'ref': self.name,
        'invoice_origin': self.name,
        'invoice_line_ids': [(0, 0, {
                    'product_id': line.service_id.id,
                    'quantity': line.quantity,
                    'name': 'pro',
                    'discount': 0,
                    'price_unit': line.price_unit
                    }) for line in self.additional_services_ids] # Multiple Invoice Line Create code here
        })
    return invoice

(0, 0, { values }) link to a new record that needs to be created with the given values dictionary
(1, ID, { values }) update the linked record with id = ID (write values on it)
(2, ID) remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)
(3, ID) cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)
(4, ID) link to existing record with id = ID (adds a relationship)
(5, 0, 0) unlink all (like using (3, ID) for all linked records)
(6, 0, [IDs]) replace the list of linked IDs (like using (5) then (4, ID) for each ID in the list of IDs)
