Hello,
In tg2.
cp model.template mymodel.py
Inside I put what? If I do this then system complains about:
recall_table = Table('recall_db', metadata, autoload=True)
class Recall(object):
def __init__(self, **kw):
"""automatically mapping attributes"""
for key, value in kw.iteritems():
setattr(self, key, value)
#Mapping of Table to Python Object Class
mapper(Recall, recall_table)
and the bottom of the __init__.py says:
from myapp.model.mymodel import Recall
That doesn work because:
sqlalchemy.exc.UnboundExecutionError: The MetaData is not bound to an
Engine or Connection. Execution can not proceed without a database to
execute against. Either execute with an explicit connection or assign
the MetaData's .bind to enable implicit execution.
So I read in __init__
def init_model(engine):
"""Call me before using any of the tables or classes in the model."""
DBSession.configure(bind=engine)
# If you are using reflection to introspect your database and create
# table objects for you, your tables must be defined and mapped inside
# the init_model function, so that the engine is available if you
# use the model outside tg2, you need to make sure this is called before
# you use the model.
#
# See the following example:
#global t_reflected
#t_reflected = Table("Reflected", metadata,
# autoload=True, autoload_with=engine)
#mapper(Reflected, t_reflected)
But what does that mean???
Where did Reflected came from??
How should I use get my model imported so it stays in the mymodel.py
file and the __init__ only imports it.?
Ideas?
Thanks,
Lucas
