Question

我正在工作Django 2.0网站，并尝试构建Django表单：

forms.py：

class NewMemberstatusform(forms.Form):
    rank = forms.ModelChoiceField(queryset=models.Rank.objects.all(), widget=forms.ModelChoiceField(
        attrs={
        'class':'form-control'
        }
    ))
    unit = forms.ModelChoiceField(queryset=models.Unit.objects.all(), widget=forms.ModelChoiceField(
        attrs={
        'class':'form-control'
        }
    ))
    activate = forms.ChoiceField(choices=YesNo.YESNO_CHOICES, label="Enable Member to see their information", widget=forms.ChoiceField(
        attrs={
        'class':'form-control'
        }
    ))

我的问题是它不能正确编译。

我收到此错误，表示我在等级字段中缺少查询集，但是如您所见，它显然在类中。我想念什么？谢谢

    class NewMemberstatusform(forms.Form):
  File "/Users/sinistersparrow/PycharmProjects/ifthqcom/app_svcrecord/forms.py", line 126, in NewMemberstatusform
    'class':'form-control'
TypeError: __init__() missing 1 required positional argument: 'queryset'

Answer 1

尝试为模型使用import语句：

from <myapp>.models import Rank, Unit

class NewMemberstatusform(forms.Form):
    rank = forms.ModelChoiceField(queryset=Rank.objects.all(), widget=forms.ModelChoiceField(
        attrs={
        'class':'form-control'
        }
    ))
    unit = forms.ModelChoiceField(queryset=Unit.objects.all(), widget=forms.ModelChoiceField(
        attrs={
        'class':'form-control'
        }
    ))
....
