Question

models.py

class User(db.Model):  
    user_id = db.StringProperty(required=True)  
    nickname = db.StringProperty(required=False)  
    email = db.StringProperty(required=False)  
    pic_url = db.StringProperty(required=False)  
    type_admin = db.BooleanProperty(default=False)  

    school = db.ReferenceProperty(School, collection_name='user_school')

class School(db.Model):  
    school_id = db.StringProperty(required=True)  
    school_name= db.StringProperty(required=True)  
    school_domain = db.StringProperty(required=False)

views.py

 uform = UserForm(instance=user)

forms.py

class UserForm(djangoforms.ModelForm):  
    class Meta:  
        model = User  
        exclude = ['user_id']

html页面

{{ uform.school }}

这会在下拉列表中返回学校对象的列表。但是，我希望下拉列表中显示school_name。我怎么做？

Answer 1

覆盖学校模型上的__unicode__方法

class School(db.Model):  
    school_id = db.StringProperty(required=True)  
    school_name= db.StringProperty(required=True)  
    school_domain = db.StringProperty(required=False) 

    def __unicode__(self):
        return self.school_name

通过表单显示引用属性的变量
