Python 将布尔字段从父类更改为子类-Odoo v8

考虑这一点：

@api.multi
@api.onchange('order_lines', 'order_lines.is_book_block', '')
@api.constrains('order_lines', 'order_lines.isbn')
def check_quantity(self):
    location = self.printer_book_block.property_stock_supplier.id
    for rec in self:
        if rec.order_lines:
            for line in rec.order_lines:
                if line.qty > line.isbn.with_context({ 'location': location, }).qty_available >= 0:#line.isbn.qty_available in location:
                    rec.write({'state': 'awaitingraw'})
                else:
                    rec.write({'state': 'work_in_progress', 'is_book_block': True})

当指定位置上有足够的产品数量（isbn）时，将文档状态更改为

work\u in\u progress

，并将布尔字段

is\u book\u block

更改为

True

状态

字段位于父模型上：

class bsi_print_order(models.Model):
_name = 'bsi.print.order'

@api.model
def create(self, vals):
    if vals.get('name', 'New') == 'New':
        vals['name'] = self.env['ir.sequence'].next_by_code('bsi.print.order') or '/'
    return super(bsi_print_order, self).create(vals)

name = fields.Char('Reference', required=True, index=True, copy=False, readonly='True', default='New')
order_lines = fields.One2many('bsi.print.order.lines', 'print_order', string="Order lines")
book_block = fields.Boolean(string="Book Block", default=True)
binding = fields.Boolean(string="Binding")
edging = fields.Boolean(string="Edging")
state = fields.Selection([
        ('draft','Draft'),
        ('awaitingraw','Awaiting raw materials'),
        ('work_in_progress','Print in Progress'),
        ('delivered','Delivered'),
        ('cancel','Cancel'),
    ], string="State")

is\u book\u block

字段位于子类

One2many order\u line字段上：

class bsi_print_order_lines(models.Model):
    _name = 'bsi.print.order.lines'

    print_order = fields.Many2one('bsi.print.order', string="Print Order")
    isbn = fields.Many2one('product.product', string="ISBN", domain="[('is_isbn', '=', True)]")
    qty = fields.Integer(string="Quantity")
    consumed_qty = fields.Integer(string="Quantity consumed")
    remaining_qty = fields.Float(string="Remaining quantity")
is_book_block = fields.Boolean(string="Is Book Block Done")
is_binding = fields.Boolean(string="Is Binding Done")
is_edging = fields.Boolean(string="Is Edging Done")
isbns = fields.Many2one('worksheets.isbns', string="Worksheet ISBNS")

还有另外两个字段
为绑定
和
为边缘

无论如何，知道其中一个就足以理解另外两个（我猜，lol），因此，由于
state
在父类上，它工作得很好，记录的状态实际上发生了变化，然而，
is\u book\u block
没有语法错误，它应该变为
True
，但是它没有，所以，我认为这是因为该方法在
order\u行上循环，但它只在父类（bsi.production.order）上更改内容

有什么想法吗？
据我所知，当你循环行时，
是一本书，块
在行中，每行都是一条记录，如果你想设置多个字段或只是更改该字段，你可以自己调用write：

  # when you change just one field no need for write just 
  rec.state = 'work_in_progress' # is enough
  # because rec.state will trigger write method
  # but for more than one field use write to trigger it only one time
  # line is a record too you can call write also if you want
  line.is_book_block = True

从onchange decorator中删除
订单行的一件事是\u book\u block
，因为您将触发对该方法的不定式调用：

  @api.onchange('order_lines')
