Question

我正在尝试制作一种表格，允许用户通过复选框列表选择雇主，这取决于他们使用ModelMultipleChoiseField的团队。我可以按团队筛选合适的雇主，但是当我选择任何一个时，我都会出错

选择一个有效的选择。 3不是可用的选择之一。

我不知道出什么问题了； /

这是我的表单类：

class TaskDictForm(forms.Form):
team_id = 0
order = forms.IntegerField(min_value=0)
name = forms.CharField(max_length=200)
start = forms.DateTimeField()
previous = forms.CharField(max_length=200)
employers = forms.ModelMultipleChoiceField(queryset=None, widget=forms.CheckboxSelectMultiple)

def __init__(self, *args, **kwargs):
    initial = kwargs.get('initial', {})
    if hasattr(self, 'initial_values') and not kwargs.get('data'):
        for field_name, value in self.initial_values.items():
            if not getattr(kwargs.get('instance', None), field_name, None):
                initial[field_name] = value

        kwargs.update({'initial': initial})
    if hasattr(self, 'required_fields'):
        for field_name in self.required_fields:
            self.fields[field_name].required = True
    tmp = kwargs.pop('pk', None)
    self.team_id = tmp
    super(TaskDictForm, self).__init__(*args, **kwargs)

    self.fields['employers'].queryset = Employer.objects.filter(team=self.team_id)

雇主和团队模型：

    class Team(models.Model):
    name = models.CharField(default='Team', max_length=100, unique=True)

    def __str__(self):
        return self.name


class Employer(models.Model):
    user = models.OneToOneField(User, on_delete=models.SET_NULL, null=True)
    team = models.ForeignKey(Team, on_delete=models.SET_NULL, null=True)
    team_leader = models.BooleanField(default=False)
    project_menager = models.BooleanField(default=False)
    # project_id = models.ForeignKey(Project, on_delete=models.SET_NULL, null=True)

    hourly_rate = models.IntegerField(default=0)
    working_time = models.FloatField(default=0.0)

    def __str__(self):
        return (self.user.first_name + ' ' + self.user.last_name)

同样的问题是当我尝试使用MultipleChoiseField

选择一个有效的选择ModelMultipleChoiceField错误
