Question

我需要一个MultipleChoiceField和在线注册应用程序。当我尝试在一个字段中使用它时，我得到一个未知的字段错误。它们也不会出现在管理面板中。

# models.py
...
CHILDCARE_REASONS = (('Working', 'working'),('Training', 'training'),('Teen Parent', 'teen_parent'),('Working W/Child With A Disability', 'child_disability'),('Adult W/Disability', 'adult_disability'),)
reasons_for_childcare = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=CHILDCARE_REASONS)
...

# forms.py
class EnrollForm(forms.ModelForm):
class Meta:
    model = EnrollmentApplication
    fields = [
        ...
        'reasons_for_childcare ',
        ...
    ]

Answer 1

不要在模型中使用表单字段，这是不对的。对于多选字段，我建议使用django-multiselectfield。
您需要更改元组顺序，首先是正确的方法，然后是值。
字段字符串“reason_for_childcare”的末尾有一个额外的空格。

因此，考虑到这一点，解决方案将如下所示：

<强> models.py

Apple

<强> forms.py

from multiselectfield import MultiSelectField


class EnrollmentApplication(models.Model):
    CHILDCARE_REASONS = (('working', 'Working'),
                         ('training', 'Training'),
                         ('teen_parent', 'Teen Parent'),
                         ('child_disability', 'Working W/Child With A Disability'),
                         ('adult_disability', 'Adult W/Disability'))
    reasons_for_childcare = MultiSelectField(choices=CHILDCARE_REASONS)
