你能告诉我我的错误在哪里吗？我不断收到FALSE form.is_valid（）

Question

您能看一下我的代码并告诉我我的错误在哪里吗？

我有一个表单类AddEditTaskForm，它具有多个字段，并且正在获取task_list以获取task.list id。

forms.py

class AddEditTaskForm(ModelForm):
def __init__(self,user,*args,**kwargs):
    super().__init__(*args,**kwargs)
    task_list=kwargs.get('initial').get('task_list')
    self.fields['task_list'].value=kwargs['initial']['task_list'].id
due_date=forms.DateField(widget=forms.DateInput(attrs={'type':'date'}),required=False)
title=forms.CharField(widget=forms.widgets.TextInput())
description=forms.CharField(widget=forms.Textarea(), required=False) 
completed=forms.BooleanField(required=False)

def clean_created_by(self):
    return self.instance.created_by

class Meta:
    model = Task
    exclude = []

呈现表单后。我收到表格无效错误。

views.py

@login_required 
def list_detail(request,list_id=None,list_slug=None,view_completed=False):
task_list=get_object_or_404(TaskList,id=list_id)
tasks=Task.objects.filter(task_list=task_list.id)
form=None
if view_completed:
    tasks=task.filter(completed=True)
else:
    tasks=tasks.filter(completed=False)
if request.POST.getlist("add_edit_task"):

    form = AddEditTaskForm(request.user,request.POST,initial={'task_list':task_list})

    if form.is_valid():
        new_task = form.save(commit=False)
        new_task.created_by = request.user
        new_task.description = bleach.clean(form.cleaned_data["description"], strip=True)
        form.save()
        messages.success(request, 'New task "{t}" has been added.'.format(t=new_task.title))
        return redirect(request.path)
    else:
        messages.success(request,'form is not valid')

context={
    'list_id': list_id,
    'list_slug': list_slug,
    'task_list': task_list,
    'tasks':tasks,
    'form':form,
    'view_completed':view_completed,
}
return render(request,'todo/list_detail.html',context)
