Django.db.utils.OperationalError: my_table has no column id error?

Question

I am testing the models.py file of my Django application: "myapp" in my Python interpreter, but continue to encounter this error:

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

I have 2 tables in my models.py, table1 and table 2.

 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

In my python interpreter:

>>> 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

However, when I exe: "manage.py sql myapp", I see for my 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")
)

You need to run python manage.py syncdb(or python manage.py migrateif you use southwhat you should) for the changes to be applied to the database.
