写入方法中的Get字段名称在odoo中出错

Question

当我编辑销售订单并保存它时，贷方和借方字段得到一个none类型的错误。我该如何解决？

Python代码：

@api.model
def create(self,vals):
logging.info("create Mehtod+++++++++++++++++++++")
logging.info(type(vals.get('credit')))
if vals.get('credit') < vals.get('debit'):
vals['check'] = True 
logging.info("Create fisrt++++++++++++++++")
else:
vals['check'] = False
logging.info("Create second++++++++++++++")
return super(sale_credit, self).create(vals)
def write(self,vals):
logging.info("Write Mehtod+++++++++++++++++++++++")
# logging.info(vals['debit'])
logging.info(type(vals.get('credit')))
logging.info(vals)
if vals['credit'] >= vals['debit']:
logging.info("FIrst write+++++++++++++")
vals['check'] = False
else:
vals['check'] = True
return super(sale_credit, self).write(vals)

我得到了这个错误日志。我有字段贷方和借方浮动字段，但我不知道为什么会出现这个错误。

KeyError: 'credit'

Answer 1

首先，这不是NoneType错误，而是KeyError，这意味着使用的密钥'credit'不在字典vals中。在奥多奥的写作方法中，这意味着这个领域没有改变。

计算check不是更容易吗？

# store=True if you want to let users search on the field
check = fields.Boolean(compute="_compute_check")  
@api.depends('debit', 'credit')
def _compute_check(self):
for record in self:
if record.credit >= record.debit:
record.check = False
else:
record.check = True
