Question

我有一个使用基于类的视图呈现的表单集。我已经阅读了django文档，并看到了与此相关的一些答案，但我无法使其正常工作。

下面的project_id = kwargs.pop('project_id',None)函数中的def get_context_data出现404错误。

当下面的project_id = kwargs.pop('project_id',None)函数中的def __init__(self,*args,**kwargs)时，表单集完全不呈现。

project_id是id模型中自动生成的ProjectDetails。

如何将project_id传递给表单集？

models.py
class ProjectDetails(models.Model):
    project_name = models.CharField(max_length = 50,blank = False)
    client = models.CharField(max_length = 200,blank = False)


class ProjectFinance(models.Model):
    project_name  = models.ForeignKey(ProjectDetails,on_delete = models.CASCADE, null = 
    True,blank=False)
    finance_item = models.CharField(max_length = 50,null=True,blank=False)


forms.py
class FianceForm(forms.ModelForm):

    def __init__(self,*args,**kwargs):
        project_id = kwargs.pop('project_id',None)
        super(FianceForm,self).__init__(*args,**kwargs)

    class Meta:
    model = ProjectFinance
    fields = '__all__'


FinanceFormSet= inlineformset_factory(ProjectDetails, ProjectFinance, form=FianceForm, fields='__all__',extra=2)


views.py
class FinanceView(CreateView):

        template_name = "project.html"
        model = ProjectFinance
        form_class = FianceForm

        def get_form_kwargs(self,*args, **kwargs):
             form_kwargs = super(FinanceView, self).get_form_kwargs(*args, **kwargs)
             form_kwargs['project_id'] = self.kwargs.get('project_id')

             return form_kwargs


        def get_context_data(self,**kwargs):
            project_id = kwargs.pop('project_id',None)
            project = get_object_or_404(ProjectDetails,id=project_id)
            formset = FinanceFormSet(instance=project)
            context = super(FinanceView, self).get_context_data(**kwargs)
            context['project'] = project

            return context

谢谢。
