Question

我有一个这样的模型：

class Package(models.Model):
    package_name = models.CharField(max_length=200)
    package_price = models.IntegerField()

class UserPackage(models.Model):
    user = models.ForeignKey(User)
    package = models.ForeignKey(Package)

ModelForm是这样的：

class UserPackageForm(ModelForm):
    class Meta:
        model = UserPackage
        exclude = ['user']

我想列出排除packages的{{1}}，这就是我这样做的原因：

Free

它也显示def __init__(self, *args, **kwargs): super(UserPackageForm, self).__init__(*args, **kwargs) self.fields['package'].queryset = Package.objects.exclude(package="Free")包。怎么了？

Answer 1

exclude参数错误，请尝试使用package_name而不是package。

from django.forms.models import BaseModelFormSet

class UserPackageForm(ModelForm):
     def __init__(self, *args, **kwargs):
            super(UserPackageForm, self).__init__(*args, **kwargs)
            self.fields['package_name'].queryset = self.fields['package_name '].queryset.exclude(package_name="Free")

Answer 2

试试这个 self.fields['package'].queryset = Package.objects.exclude(package__name="Free")

在“模型表单”中的“外键”下拉列表中排除一个“字段”值
