字典更新序列元素 # 0的长度为3; 需要2

我想通过其他对象向对象 account.bank.statement.line添加线条，但是我得到以下错误:

字典更新序列元素 # 0的长度为3; 需要2

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

我改变了它，但是我遇到了这个错误:

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) 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
})

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

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)

I was getting this error when I was updating the dictionary with the wrong syntax:

Try with these:

lineItem.values.update({attribute,value})

instead of

lineItem.values.update({attribute:value})

One of the fast ways to create a dict from equal-length tuples:

>>> t1 = (a,b,c,d)
>>> t2 = (1,2,3,4)
>>> dict(zip(t1, t2))
{'a':1, 'b':2, 'c':3, 'd':4, }

Not really an answer to the specific question, but if there are others, like me, who are getting this error in fastAPI and end up here:

It is probably because your route response has a value that can't be JSON serialised by jsonable_encoder. For me it was WKBElement: https://github.com/tiangolo/fastapi/issues/2366

Like in the issue, I ended up just removing the value from the output.

When I was trying to convert a dict to a list using .values()

Solved it by using .items()

list(dict(new_row.items()))

To anyone following patrick collins video[1] on smart contract development who runs into this error code; in the brownie-config.yaml file I had an '=' instead of a '-' in the following line(s)

...
compiler:
solc:
remappings:
= '@openzeppelin=OpenZeppelin/openzeppelin-        contracts@4.2.0'

The first '=' should be '-'. The second one is as it should be.
