Django表单初始化覆盖'；选择一个有效选项'；表单验证错误

我正试图覆盖

\uuu init\uuuu

方法，以更新表单

角色

字段上的查询集。这将引发一个验证错误，该错误表示：

选择一个有效的选项。该选择不是可用的选择之一

..然后返回此

角色
字段中没有选项的表单

forms.py

class UserRegisterForm(UserCreationForm):
    role = forms.ModelChoiceField(
        queryset=EmployeeType.objects.all(),
        empty_label=None,
        required=False)
    supervisor = forms.ModelChoiceField(
        queryset=Employee.objects.all(),
        required=False)

    def __init__(self, *args, **kwargs):
        self.company = (kwargs.pop('company', None))
        super(UserRegisterForm, self).__init__(*args, **kwargs)
        self.fields['role'].queryset = EmployeeType.objects.filter(company=self.company)
        self.fields['supervisor'].queryset = Employee.objects.filter(company=self.company, supervisor=None)

def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            employee = Employee.objects.get(username=form.instance)
            user_count = request.tenant.employee_set.count()
            if user_count > 1:
                form.instance.is_active = False
            if form.instance.role:
                group_obj = form.instance.role.group
                group = Group.objects.get(name=group_obj)
                employee.groups.add(group)
            company = request.tenant
            form.instance.company = company
            return redirect('verify-redirect')
    else:
        form = UserRegisterForm(company=request.tenant)
    return render(request, 'employees/register.html', {'form': form})

视图.py

        self.fields['role'].queryset = EmployeeType.objects.filter(company=self.company)
        self.fields['supervisor'].queryset = Employee.objects.filter(company=self.company, supervisor=None)

            if user_count > 1:
                form.instance.is_active = False
            if form.instance.role:
                group_obj = form.instance.role.group
                group = Group.objects.get(name=group_obj)
                employee.groups.add(group)
            company = request.tenant
            form.instance.company = company
            return redirect('verify-redirect')
    else:
        form = UserRegisterForm(company=request.tenant)
    return render(request, 'employees/register.html', {'form': form})

如何修复表单验证错误？
当请求方法为POST时，初始化表单时您没有传递
公司

form = UserRegisterForm(request.POST)

这导致您将
角色
字段的查询集设置为
员工类型
s，其中公司为空

# self.company will be None
self.fields['role'].queryset = EmployeeType.objects.filter(company=self.company)

你需要通过公司

form = UserRegisterForm(request.POST, company=request.tenant)    

你能分享初始化表单的视图吗？绝对可以！我希望不需要：）一秒钟。。
