Hi,
I have a "Main Application", and in this application I have the
following in the _init_.py file:
def main(global_config, **settings):
# various config settings
config.include(site_configs)
def site_configs(config):
config.add_route('portfolio', '/portfolio',
view='mainapp.views.portfolio', view_renderer='/site/portfolio.mako')
And in the views.py I have:
def portfolio(request):
## some code here
project_records = dbsession.query(projects).from_statement('SELECT
* FROM projects ORDER by id DESC').all()
return {'project_records': project_records}
And then I have a new application, which I want to extend.
So in the __init__.py I have done:
from mainapp import site_configs
def main(global_config, **settings):
# various config settings
config.include(site_configs)
But when I run this new application, I get the following error (full
traceback at the bottom of this message):
UnboundExecutionError: Could not locate a bind configured on mapper
Mapper|projects|projects, SQL expression or this Session
- The sqlalchemy engine has been properly set up in both
applications.
Also what I want to do is use the database in the new application and
not the one in the original main application.
