int（）参数必须是一个字符串或数字，而不是'QueryDict' [英] int() argument must be a string or a number, not 'QueryDict'

问题描述

我在表单上渲染3个多个选择框。
我正在对每个框进行过滤，使其具有单独的一天。
当我提交表单时，我收到这个错误。

  int（）参数必须是字符串或数字，不是'QueryDict'
  

我要做什么来保存我的表单？ / p>

这是我在我的forms.py文件上做的，以获取每个选择框的不同过滤。

  class ContractForm（forms.ModelForm）：
 
 def __init __（self，project_id，* args，** kwargs）：
 super（ContractForm，自己）___（* 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）
  

---

我得到我的project_id像这样： p>

  def editcontract（reque st，contract_id，slug）：
 context_dict = {} 
 contract = get_object_or_404（Contract，pk = contract_id）
如果request.method =='POST'：
 form = ContractForm （request.POST，instance = contract）
如果form.is_valid（）：
 form.save（）
 TvUsageForm = TvUsageFormSet（request.POST，instance = contract）
 AdditionalMediaUsageForm = AdditionalMediaUsageFormSet（request.POST，instance = contract）
 TvUsageForm.save（）
 AdditionalMediaUsageForm.save（）
返回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 = {'for m'：form，
'tvusage_form'：TvUsageForm，
'additional_form'：AdditionalMediaUsageForm，
'project'：project 
} 
 return render_to_response（'contracts / edit_contract .html'，context_dict，RequestContext（request））
  

解决方案

您对参数列表和关键字参数有混淆：

而不是：

  ContractForm（instance = contract，project_id = contract.project_id）
  

p>

  ContractForm（contract.project_id，instance = contract）
  

要详细说明：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。所以你需要把它作为第一个参数。简单的混乱，嗯？

I'm rendering out 3 multiple select boxes on my form. I'm filtering each box out to have a seperate type of day. When I submit my form I get this error.

int() argument must be a string or a number, not 'QueryDict'

What must I do to save my form?

This is what i'm doing on my forms.py file to get the different filtering for each select box.

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)

I'm getting my project_id like so:

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))

解决方案

You have a confusion with the argument list and keyword arguments:

Instead of:

ContractForm(instance=contract, project_id=contract.project_id)

You want:

ContractForm(contract.project_id, instance=contract)

To elaborate: Your constructor accepts the project id as first argument not as keyword argument. Thus you need to give it as first argument. Simple confusion, eh?
