我有一个使用user作为forgignKey的模型。在管理员,我需要它显示为用户名的全名instread。然后我申请了
class CollaboratorInLine(admin.StackedInline):
model = Collaborator
#list_display = ('collaborator__collaborator_first_name')
extra = 0
form =CollaboratorForm
#raw_id_fields=("collaborator",)
def formfield_for_foreignkey(self, db_field, request=None, **kwargs):
field = super(CollaboratorInLine, self).formfield_for_foreignkey(
db_field, request, **kwargs)
if db_field.rel.to == User:
field.label_from_instance = self.get_user_label
return field
def formfield_for_manytomany(self, db_field, request=None, **kwargs):
field = super(CollaboratorInLine, self).formfield_for_manytomany(
db_field, request, **kwargs)
if db_field.rel.to == User:
field.label_from_instance = self.get_user_label
return field
def get_user_label(self, user):
name = user.get_full_name()
return name
它可以作为带有全名的下拉列表正常工作。然后我想按字母顺序对它们进行排序。 然后我appplied
class CollaboratorForm(forms.ModelForm):
collaborator = forms.ModelChoiceField(queryset=User.objects.order_by('first_name'))
#assert False,collaborator
class Meta:
model = Collaborator
如此应用。全名再次成为用户名。如果我删除它,它会成为全名。 那我怎么能保留这两个功能呢?
感谢

尝试继承ModelChoiceField
并覆盖label_for_instance
方法以显示全名。
class MyModelChoiceField(ModelChoiceField):
def label_from_instance(self, obj):
return obj.get_full_name()
然后在模型表单中使用新字段。
class CollaboratorForm(forms.ModelForm):
collaborator = MyModelChoiceField(queryset=User.objects.order_by('first_name'))
#assert False,collaborator
class Meta:
model = Collaborator
