解决 AttributeError: 'ForeignKey' object has no attribute 're'

解决办法

# print('rel...',filter_field_obj.re.to.objects.all())

print("rel...", filter_field_obj.remote_field.model.objects.all())

 

 

步骤

按照视频中老师的一步步，然后就报错了。。。。。。郁闷

forekey中存在rel，诶什么不能调用？

 

 

 

 

publish 1111111111
app01.Book.publish 2222222222
<class 'django.db.models.fields.related.ForeignKey'>
rel... {'name': 'publish', 'verbose_name': 'publish', '_verbose_name': None, 'primary_key': False, 'max_length': None, '_unique': False, 'blank': False, 'null': False,
 'remote_field': <ManyToOneRel: app01.book>, 'is_relation': True, 'default': <class 'django.db.models.fields.NOT_PROVIDED'>, 'editable': True,
 'serialize': True, 'unique_for_date': None, 'unique_for_month': None, 'unique_for_year': None, 'choices': [], 'help_text': '', 'db_index': True,
 'db_column': None, '_db_tablespace': None, 'auto_created': False, 'creation_counter': 69, '_validators': [], '_error_messages': None, 
'error_messages': {'invalid_choice': 'Value %(value)r is not a valid choice.', 'null': 'This field cannot be null.', 'blank': 'This field cannot be blank.', 
'unique': '%(model_name)s with this %(field_label)s already exists.', 'unique_for_date': '%(field_label)s must be unique for %(date_field_label)s %(lookup_type)s.', 
'invalid': '%(model)s instance with %(field)s %(value)r does not exist.'}, 'from_fields': ['self'], 'to_fields': ['nid'], 'swappable': True, 'db_constraint': True, 
'attname': 'publish_id', 'column': 'publish_id', 'concrete': True, 'model': <class 'app01.models.Book'>, 'opts': <Options for Book>, 'related_model': <class 'app01.models.Publish'>, 
'validators': [], '_related_fields': [(<django.db.models.fields.related.ForeignKey: publish>, <django.db.models.fields.AutoField: nid>)]}

 

故：

self.remote_field = rel

 

 

 如何取出对应的数据

 

 

大功告成

            # print('rel...',filter_field_obj.re.to.objects.all())
            print('rel...',filter_field_obj.__dict__)
            print('rel...',filter_field_obj.remote_field)
            print('rel...',filter_field_obj.remote_field.__dict__)
            print("rel...", filter_field_obj.remote_field.model.objects.all())
