Hello,
Has anyone encountered the following when running nosetest and
sqlalchemy:
ERROR: tests.test_model.TestMe.test_empty
----------------------------------------------------------------------
Traceback (most recent call last):
File

1444, in class_mapper
InvalidRequestError: Class 'Book' entity name 'None' has no mapper
associated with it
I am using tg 1.0b2
tg-admin quickstart -s -i tgtest
In my model.py I have
from sqlalchemy.ext.assignmapper import assign_mapper
book_table = Table('book', metadata,
Column('id', Integer, primary_key=True),
Column('title', String, nullable=False, unique=True)
)
class Book(object):
pass
assign_mapper(session.context, Book, book_table)
In my test_model.py I have
from sqlalchemy import *
from turbogears import config, redirect, expose, database,
errorhandling
from turbogears.testutil import create_request, capture_log, print_log,
sqlalchemy_cleanup
from turbogears.database import metadata, bind_meta_data, session
from tgtest import model
from tgtest.model import Book
config.update({"sqlalchemy.dburi" : "sqlite:///:memory:"})
bind_meta_data()
metadata.engine.echo = True
class TestMe:
def setUp(self):
metadata.create_all()
def tearDown(self):
sqlalchemy_cleanup()
def test_empty(self):
entry = list(Book.select())
assert len(entry) is 0
def test_add(self):
b = Book()
b.title = 'Harry Potter and the Half-blood Prince'
session.flush()
entry = list(Book.select())
assert len(entry) is 1
Best regards,
Dakila
