Python 无法在Django上填写自定义choicefield表单
我是DJango的新手,我试图用自定义数据填充choicefield表单,但我遇到了一个我不太理解的错误 在我的Python 无法在Django上填写自定义choicefield表单,python,django,forms,choicefield,Python,Django,Forms,Choicefield,我是DJango的新手,我试图用自定义数据填充choicefield表单,但我遇到了一个我不太理解的错误 在我的视图.py上,我有: def simpleDeploy(request): networkList = getDetailsNetworkPartitions(request) policiesList = getDetailsApplicationPolicies(request) if request.method == 'POST': ab
视图.py上,我有:
def simpleDeploy(request):
networkList = getDetailsNetworkPartitions(request)
policiesList = getDetailsApplicationPolicies(request)
if request.method == 'POST':
abs(5) #Don't do nothing by the moment, I need put something or I get an error
else:
simpleForm = SimpleDeploy(netList=networkList, polList=policiesList)
return render(request, 'apacheStratos/simpleDeploy.html', {'form': simpleForm})
我的forms.py
是:
class SimpleDeploy(forms.Form):
def __init__(self, networkList, policiesList, *args, **kwargs):
super(SimpleDeploy, self).__init__(*args, **kwargs)
if networkList and policiesList:
self.fields['networkPartitions'] = forms.ChoiceField(choices=networkList)
self.fields['applicationPolicies'] = forms.ChoiceField(choices=policiesList)
else:
self.fields['networkPartitions'] = forms.ChoiceField(choices='No network partitions found')
self.fields['applicationPolicies'] = forms.ChoiceField(choices='No application policies found')
Django抛出的错误是:\uuuu init\uuuuuuu()在simpleForm=SimpleDeploy(netList=networkList,polList=policiesList)行上至少接受3个参数(1个给定)
我不知道为什么会说,如果我通过了2,那么接受3个参数,然后给出1
我做错了什么?谢谢

看起来您使用了不同的键,并且缺少位置参数。您发送的参数被视为kwargs
在表单的\uuuu init\uuuu
中,您需要以下参数
def __init__(self, networkList, policiesList, *args, **kwargs):
但是您发送时使用了键netList
,以及polList
,因此出现了错误
尝试:
甚至只是
simpleForm = SimpleDeploy(netList, polList)
请注意,我不知道您的局部变量名是什么,所以请相应地更新它们 看起来您使用了不同的键,并且缺少位置参数。您发送的参数被视为kwargs
