如何将方法行减少为循环？

Question

我怎样才能将我的代码留在一个循环中？它限制了我这样做，因为它们具有不同的定义，所以我无法减少代码行。

  input_quantity= fields.Float(string="input_quantitya", compute="input_quantity")
  @api.one
  @api.depends ("detail_book_ids")
  def _stock_entry (self):
      sum = 0
      for detail_book in self.detail_book_ids:
          sum + = book_detail.quantity_debted
      self.input_quantity = sum

  merge_number= fields.Float(string="merge_number", compute="_stock_merma")    
  @api.one
  @api.depends ("detail_book_ids")
  def _stock_merma (self):
      sum = 0
      for detail_book in self.detail_book_ids:
          sum + = detail_book.quantity_merm
      self.merge_number = sum

  output_quantity= fields.Float(string="output_quantity", compute="_stock_output")
  @api.one
  @api.depends ("detail_book_ids")
  def _stock_output (self):
      sum = 0
      for detail_book in self.detail_book_ids:
          sum + = book_detail.quantity_to have
      self.output_quantity = sum

我需要这样做，因为这就是我收到以下错误的原因： RecursionError：调用 Python 对象时超出了最大递归深度。

计算库存的字段如下

  stock= fields.Float(string="stock", compute="_stock")
  @api.one
  @api.depends('input_quantity','output_quantity','existencia','merge_numbe')
  def _stock(self):
      for rec in self:
          rec.stock = rec.existencia + (rec.input_quantity - (rec.output_quantity + rec.merge_numbe))

你好弗朗西斯科·冈萨雷斯·梅亚斯，

以这种方式优化方法，只需为你的所有领域调用一个方法与减少线。

@api.multi
def _compute_common_funtion(self):
    self.input_quantity = sum(self.mapped('detail_book_ids').mapped('quantity_debted'))
    self.merge_number = sum(self.mapped('detail_book_ids').mapped('quantity_merm'))
    self.output_quantity = sum(self.mapped('detail_book_ids').mapped('quantity_to'))

谢谢

您可以像他们在sale module 中那样做。

@api.depends("detail_book_ids")
def _amount_all(self):
    for stock_entry in self:
        input_quantity = merge_number = output_quantity = 0.0
        for detail_book in stock_entry.detail_book_ids:
            input_quantity += detail_book.quantity_debted
            merge_number += detail_book.quantity_merm
            output_quantity += detail_book.quantity_to_have

        # 1 database update
        stock_entry.update({
            'input_quantity': input_quantity,
            'merge_number': merge_number,
            'output_quantity': output_quantity,
        })

您可以像以前一样保留@api.one，并删除_compute_all 方法中的第一个循环，然后将stock_entry 重命名为self。

编辑：

您有一个依赖于其他计算字段的字段，如果您引用会计发票_compute_amount 方法，则可以使用相同的方法并在装饰器中添加新的 depandeances。

@api.one
@api.depends('detail_book_ids', 'existencia')
def _amount_all(self):
    input_quantity = merge_number = output_quantity = 0.0
    for detail_book in self.detail_book_ids:
        input_quantity += detail_book.quantity_debted
        merge_number += detail_book.quantity_merm
        output_quantity += detail_book.quantity_to_have

    self.input_quantity = input_quantity
    self.merge_number = merge_number
    self.output_quantity = output_quantity
    self.stock = self.existencia + (input_quantity - (output_quantity + merge_number))
