我在表单上渲染了3个多选框。 我正在过滤每个盒子以分开一天。 当我提交表单时,我收到此错误。
int() argument must be a string or a number, not 'QueryDict'
我该怎样做才能保存表单?
这就是我在forms.py文件中执行的操作,以便为每个选择框进行不同的过滤。
class ContractForm(forms.ModelForm):
def __init__(self, project_id, *args, **kwargs):
super(ContractForm, self).__init__(*args, **kwargs)
self.fields['shoot_day'].queryset = Day.objects.filter(type=SHOOT, project__id=project_id)
self.fields['travel_day'].queryset = Day.objects.filter(type=TRAVEL, project__id=project_id)
self.fields['additional_day'].queryset = Day.objects.filter(type=ADDITIONAL, project__id=project_id)
我正在获取我的project_id:
def editcontract(request, contract_id, slug):
context_dict = {}
contract = get_object_or_404(Contract, pk=contract_id)
if request.method == 'POST':
form = ContractForm(request.POST, instance=contract)
if form.is_valid():
form.save()
TvUsageForm = TvUsageFormSet(request.POST, instance=contract)
AdditionalMediaUsageForm = AdditionalMediaUsageFormSet(request.POST, instance=contract)
TvUsageForm.save()
AdditionalMediaUsageForm.save()
return HttpResponseRedirect(reverse('contract_list', kwargs={'slug':slug}))
else:
form = ContractForm(instance=contract, project_id=contract.project_id)
TvUsageForm = TvUsageFormSet(instance=contract)
AdditionalMediaUsageForm = AdditionalMediaUsageFormSet(instance=contract)
project = get_object_or_404(Project, slug=slug)
context_dict = { 'form': form,
'tvusage_form':TvUsageForm,
'additional_form':AdditionalMediaUsageForm,
'project':project
}
return render_to_response('contracts/edit_contract.html', context_dict, RequestContext(request))

您对参数列表和关键字参数感到困惑:
而不是:
ContractForm(instance=contract, project_id=contract.project_id)
你想:
ContractForm(contract.project_id, instance=contract)
详细说明:您的构造函数接受项目id作为第一个参数而不是关键字参数。因此,您需要将其作为第一个参数。简单的困惑,嗯?
