Question

I am creating UserResource and UserProfileResource. When I create a new user I see that my userprofile database table is also being updated. Which is good. But when I GET the user I get an error saying:

The model    has an empty attribute  profile  and doesn t allow a null value.

我的法典:

资源。

class UserProfileResource(ModelResource):
    home_address = fields.CharField(attribute= home_address )
    user = fields.ToManyField( resources.UserResource , attribute= user , related_name= profile )
    class Meta:
        queryset = UserProfile.objects.all()
        resource_name =  profile 
        allowed_methods = [ get ,  post ,  delete ,  put ]
        fields = [ home_address ]
        authorization = Authorization()
        include_resource_uri = False
        include_absolute_url = False

class UserResource(ModelResource):
    profile = fields.ToOneField( resources.UserProfileResource , attribute =  profile , related_name= user , full=True)
    class Meta:
        queryset = User.objects.all()
        resource_name =  user 
        allowed_methods = [ get ,  post ,  delete ,  put ]
        fields = [ username ]
        filtering = {
                 username : ALL,
                }
        authorization = Authorization()

    def obj_create(self, bundle, request=None, **kwargs):
        try:
            bundle = super(UserResource, self).obj_create(bundle, request, **kwargs)
            bundle.obj.set_password(bundle.data.get( password ))
            bundle.obj.save()
        except IntegrityError:
            raise BadRequest( IntegrityError )
        return bundle

models.py

class UserProfile(models.Model):
    user = models.ForeignKey(User, unique=True)
    home_address = models.TextField()

Anyone any ideas? johnoc

在进行了大量搜查之后,我终于回答这一问题。

模式。 y

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    home_address = models.TextField()

resources.py

class UserProfileResource(ModelResource):
    class Meta:
        queryset = UserProfile.objects.all()
        resource_name =  profile 
        allowed_methods = [ get ,  post ,  delete ,  put ]
        fields = [ home_address ]
        authorization = Authorization()
        include_resource_uri = False
        include_absolute_url = False

class UserResource(ModelResource):
    profile = fields.ToOneField( resources.UserProfileResource , attribute =  userprofile , related_name= user , full=True, null=True)
    class Meta:
        queryset = User.objects.all()
        resource_name =  user 
        allowed_methods = [ get ,  post ,  delete ,  put ]
        fields = [ username ]
        filtering = {
                 username : ALL,
                }
        authorization = Authorization()

    def obj_create(self, bundle, request=None, **kwargs):
        try:
            bundle = super(UserResource, self).obj_create(bundle, request, **kwargs)
            bundle.obj.set_password(bundle.data.get( password ))
            bundle.obj.save()
        except IntegrityError:
            raise BadRequest( IntegrityError )
        return bundle

这一工作。请注意,模型领域已改为“一对一”外地,而资源归属现已成为“用户简介”。我希望这能帮助人们走出来!
