python - Flask - Trying to add an ID field in database which is incremented each time -


this code models.py file. working until tried add new field "id" gets incremented each item. flask app running on google app engine.

from google.appengine.ext import db  class post(db.model):     id = db.column(db.integer, primary_key=true)     title = db.stringproperty(required = true)     content = db.textproperty(required = true)

this traceback get:

<type 'exceptions.attributeerror'>: 'module' object has no attribute 'column' traceback (most recent call last):   file "/base/data/home/apps/s~smart-cove-95709/1.384688470778541604/main.py", line 2, in <module>     blog import app   file "/base/data/home/apps/s~smart-cove-95709/1.384688470778541604/blog/__init__.py", line 7, in <module>     import views   file "/base/data/home/apps/s~smart-cove-95709/1.384688470778541604/blog/views.py", line 2, in <module>     models import post   file "/base/data/home/apps/s~smart-cove-95709/1.384688470778541604/blog/models.py", line 3, in <module>     class post(db.model):   file "/base/data/home/apps/s~smart-cove-95709/1.384688470778541604/blog/models.py", line 4, in post     id = db.column(db.integer, primary_key=true)

i tried without success:

class post(db.model):     id = db.integer(primary_key=true)     title = db.stringproperty(required = true)     content = db.textproperty(required = true)

column not member sine you're not using sqlalchemy.

i think model google.appengine.ext.db has key out of box, refer google documentation
