python – django.db.utils.OperationalError：my_table没有列ID

django.db.utils.OperationalError: table myapp_table1 has no column named attribute1_id

我的models.py,table1和表2中有2个表.

class table1 (models.Model):
   name = models.CharField(max_length=25)
   def __str__(self):             
     return self.name
 class table2 (models.Model):
   name = models.CharField(max_length =25)
   attribute1= models.ForeignKey(Type,related_name = "att1_set+",default=None)
   attribute2= models.ManyToManyField(Type,related_name = "att2_set+",default=None)
   def __str__(self):             
     return self.metric_name

在我的python解释器中：

>>> from my_app.models import table1,table2
>>> t1 = table1 (name = "ty1",id = 0)
>>> t1.save()
>>> t2 = table1 (name = "ty2",id = 1)
>>> e1 = table2 (name = "as",attribute1 = t1)
>>> e1.save() 
>>> error aforementioned after .save

但是,当我执行：“manage.py sql myapp”时,我看到我的table2：

CREATE TABLE "my_app_table2" (
"id" integer NOT NULL PRIMARY KEY AUTOINCREMENT,"name" varchar(25) NOT NULL,"attribute1_id" integer NOT NULL REFERENCES "myapp_table1" ("id")
)
