Question

我正在尝试将一个复选框添加到表单，如果为true，我希望它向manytomanyfield的贯穿模型添加一行，但是我无法访问该复选框变量。这是我添加到的表单，它按预期出现，所以只有一半：

class ProjectUpdateForm(forms.ModelForm):
    completed = forms.BooleanField(). # this variable here

    class Meta:
        model = Update
        fields = [
            'category',
            'update'
        ]

我认为我希望对此进行处理：

def project_update_view(request, slug):
    obj = Project.objects.get(slug=slug)
    if request.method == 'POST':
        form = ProjectUpdateForm(request.POST)
        form.instance.project = obj
        if form.is_valid():
            print(f"================{form.completed}") # attempt to find variable
            form.save()
            return redirect('project-list')
    else:
        form = ProjectUpdateForm()

    context = {
        "form": form,
        "object": obj
    }
    return render(request, 'project_portal/project_update.html', context)

这给我标题中的错误。所以我现在不明白什么是属性，我认为这是变量代表的类的一个方面。如何访问此复选框变量，以便可以使用它？

它的格式为cleaned_data

def project_update_view(request, slug):
    obj = Project.objects.get(slug=slug)
    if request.method == 'POST':
        form = ProjectUpdateForm(request.POST)
        form.instance.project = obj
        if form.is_valid():
            print(form.cleaned_data['completed'])
            form.save()
            return redirect('project-list')

AttributeError：ProjectUpdateForm对象没有完成的属性
