Question

我有两种模式：

class Vehicle(Model):
    name = models.CharField(max_length=50)

class Driver(Model):
    vehicle = models.ForeignKey(Vehicle, related_name='owned_vehicle')
    name = models.CharField(max_length=100)

现在在我的forms.py上：

class MyForm(forms.Form):
    drivers = Driver.objects.order_by('name')
    drivers_list = forms.ModelChoiceField(drivers, empty_label='* Driver *', label='Driver')

问题是drivers_list还包括列表中的vehicles。如何防止此表单将ForeignKey字段包含在ModelChoiceField中？

Answer 1

为什么不使用驱动程序的模型表单，

class DriverForm(forms.ModelForm):
    class Meta:
        model = Article
        fields = ['name', 'vehicle']

对于您自己的表单，

class MyForm(forms.Form):
    driver_list = forms.ModelChoiceField(queryset=Driver.objects.order_by('name'))
    # then other attributes which you want to map with driver

Django从ModelChoiceField中排除ForeignKey字段
