关于这个方法：
@api.multi
@api.onchange('order_picking')
@api.constrains('order_picking', 'order_picking.isbn')
def check_quantity(self):
location = self.printer_book_block.property_stock_supplier.id
for rec in self:
if rec.order_picking:
for line in rec.order_picking:
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',})
它抛出了我：

违规行是：
rec.write({'state': 'awaitingraw'})
此方法检查产品线（isbn）以查看是否有足够的数量，如果没有，它会继续awaitingraw，如果有足够的数量，则它会转到work_in_progress。但这很奇怪，我添加这个方法（check_quantity之前）后出现错误：
@api.multi
@api.depends('order_picking', 'order_picking.isbn', 'contract_worksheet', 'state')
def accounting_scenarios(self):
for record in self:
if not len(record.transporter):
raise Warning('Please Enter Transporter !')
elif not len(record.transporter.transp_transit):
raise Warning('Please assign transit account to the transporter !')
if record.state in ('awaitingraw'):
record.temp = record.contract_worksheet.total_alles - record.contract_worksheet.total_totals
acc_move = self.env['account.move']
move_lines = [
(0, 0, {
'name': 'name',
'debit': record.temp or 0.0,
'credit': 0,
'account_id': record.transporter.transp_transit.id,
'date': fields.Date.today(), #date,
'partner_id': record.transporter.id, # partner if there is one
#'currency_id': currency_id or (account.currency_id.id or False),

'date': fields.Date.today(), #date,

#'currency_id': currency_id or (account.currency_id.id or False),
})
]
journal_id = False
if record.transporter.transp_transit:
journals = self.env['account.journal'].search([
('default_debit_account_id', '=', record.transporter.transp_transit.id)
])
if journals:
journal_id = journals[0].id
acc_move.create({
#'period_id': period_id, #Fiscal period
'journal_id': journal_id,
'date': fields.Date.today(),
'state': 'draft',
'line_id': move_lines,
})
#return move.id
elif record.state in ('work_in_progress'):
record.temp2 = record.contract_worksheet.total_totals
elif record.state in ('delivered'):
record.transporter.transp_transit.debit = record.contract_worksheet.total_alles
现在似乎有效，所以，有什么想法吗？
修改
此外，当我尝试编辑记录并编辑字段printer_book_block时，保存它会抛出：
ValidateError
Error while validating constraint
8
这是字段：
printer_book_block = fields.Many2one('res.partner', string="Printer Book Block")
编辑2
似乎问题是printer_book_block Many2one到res.partner之间的问题，以及我正在工作的类ID，它每次存储的序列ID创建了新记录，我看到这个8作为文档的id，对于我尝试编辑的任何内容都是如此。
错误发生了，它只是明显地改变了数字，这取决于我正在编辑哪一个，非常令人费解......
答案 0 :(得分：1)
首先，您需要在for循环中移动此行，并从rec而不是self获取位置。
for rec in self:
location = rec.printer_book_block.property_stock_supplier.id
现在我没有看到这里的错误，所以你评论所有位置的位置和数量可用数量这个错误仍然会提高
