字典更新序列元素#0的长度为3； 2个为必填项

问题描述

我想通过其他对象向对象account.bank.statement.line添加行，但是出现以下错误:

I want to add lines to the object account.bank.statement.line through other object But I get following error:

这是我的代码:

def action_account_line_create(self, cr, uid, ids):
    res = False
    cash_id = self.pool.get('account.bank.statement.line')
    for exp in self.browse(cr, uid, ids):
        company_id = exp.company_id.id
        #statement_id = exp.statement_id.id
        lines = []
        for l in exp.line_ids:
            lines.append((0, 0, {
                'name': l.name,
                'date': l.date,
                'amount': l.amount,
                'type': l.type,
                'statement_id': exp.statement_id.id,
                'account_id': l.account_id.id,
                'account_analytic_id': l.analytic_account_id.id,
                'ref': l.ref,
                'note': l.note,
                'company_id': l.company_id.id
            }))

        inv_id = cash_id.create(cr, uid, lines,context=None)
        res = inv_id
    return res

我对此进行了更改，但随后遇到此错误:

I changed it on that but then I ran into this error:

def action_account_line_create(self, cr, uid, ids, context=None):
    res = False
    cash_id = self.pool.get('account.bank.statement.line')
    for exp in self.browse(cr, uid, ids):
        company_id = exp.company_id.id
        lines = []
        for l in exp.line_ids:
            res = cash_id.create ( cr, uid, {
                'name': l.name,
                'date': l.date,

                'company_id': l.company_id.id
            }, context=None)
    return res

推荐答案

出现此错误是因为您尝试通过使用错误的序列(list或tuple)结构来更新dict对象.

This error raised up because you trying to update dict object by using a wrong sequence (list or tuple) structure.

cash_id.create(cr, uid, lines,context=None)试图将lines转换为字典对象:

cash_id.create(cr, uid, lines,context=None) trying to convert lines into dict object:

(0, 0, {
    'name': l.name,
    'date': l.date,
    'amount': l.amount,
    'type': l.type,
    'statement_id': exp.statement_id.id,
    'account_id': l.account_id.id,
    'account_analytic_id': l.analytic_account_id.id,
    'ref': l.ref,
    'note': l.note,
    'company_id': l.company_id.id
})

从该元组中删除第二个零，以将其正确转换为dict对象.

Remove the second zero from this tuple to properly convert it into a dict object.

要自我测试，请在python shell中进行尝试:

To test it your self, try this into python shell:

>>> l=[(0,0,{'h':88})]
>>> a={}
>>> a.update(l)

Traceback (most recent call last):
  File "<pyshell#11>", line 1, in <module>
    a.update(l)
ValueError: dictionary update sequence element #0 has length 3; 2 is required

>>> l=[(0,{'h':88})]
>>> a.update(l)
