提交 ChoiceField 表单 Django
Submit ChoiceField form Django
我正在处理如何在 Django 中制作自定义表单,现在我卡在了提交步骤。
当我按下提交时,我得到一个 __init__() got multiple values for keyword argument 'networkList'
。
我的forms.py
是:
class SimpleDeploy(forms.Form):
def __init__(self, networkList, policiesList, applicationList, *args, **kwargs):
super(SimpleDeploy, self).__init__(*args, **kwargs)
if networkList and policiesList and applicationList:
self.fields['Network Partition ID:'] = forms.ChoiceField(choices=networkList)
self.fields['Application Policy ID:'] = forms.ChoiceField(choices=policiesList)
self.fields['Application ID:'] = forms.ChoiceField(choices=applicationList)
else:
self.fields['Network Partition ID:'] = forms.ChoiceField(choices='No network partitions found')
self.fields['Application Policy ID'] = forms.ChoiceField(choices='No application policies found')
self.fields['Application ID:'] = forms.ChoiceField(choices='No applications found')
在我的 views.py
上,方法如下所示:
def simpleDeploy(request):
netList = getDetailsNetworkPartitions(request)
polList = getDetailsApplicationPolicies(request)
appList = getDetailsApplications(request)
if request.method == 'POST':
form = SimpleDeploy(request.POST, networkList=None, policiesList=None, applicationList=None)
if form.is_valid():
network = form.cleaned_data['Network Partition ID:']
policy = form.cleaned_data['Application Policy ID:']
application = form.cleaned_data['Application ID:']
##### more things
else:
simpleForm = SimpleDeploy(networkList=netList, policiesList=polList, applicationList=appList)
else:
simpleForm = SimpleDeploy(networkList=netList, policiesList=polList, applicationList=appList)
return render(request, 'apacheStratos/simpleDeploy.html', {'form': simpleForm})
回溯错误:

Exception Value: __init__() got multiple values for keyword argument 'networkList'
查看文档,我读到 POST 请求它始终是第一个参数 (request.Post
) 并且在 init 方法上我认为它与 self
相对应,而且在这里的其他答案中,我看到有时,把 data=params
工作但在我的情况下我得到一个错误: need more than 1 value to unpack
在行 if form.is_valid():

所以,我的错误在哪里?谢谢和问候。
您已经定义了表单初始化,因此第一个位置参数是 networkList
;因此,当您执行 form = SimpleDeploy(request.POST, networkList=None...)
时,位置参数和关键字参数都使用相同的名称,这是不允许的。
根本不要更改签名;从 kwargs 获取额外的值。
def __init__(self, *args, **kwargs):
networkList = kwargs.pop('networkList', None)
policiesList = kwargs.pop('policiesList', None)
applicationList = kwargs.pop('applicationList', None)
super(...)
或者,由于您只需要表单中的那些值,您可以考虑将请求传递给此方法并直接在那里获取这些值;将应用相同的语法。
