Some trouble with SQLAlchemy. Solved inside.

[Maxim Oganesyan]

Today I started new project on TG2.
While using tutorial from here after step...

$ paster setup-app development.ini

... I've got an error:

cannot import name exceptions

Error rised by called migration module after model tables were created.

Solved by typing (TurboGears enviroment was active):

$ pip uninstall sqlalchemy

$ pip install sqlalchemy==0.7.9

Looks like SQLA >= 0.8 is beta, so better to use 0.7.9 version.

Best regards.
Maxim.

Yes, it's a known issue, it got solved on development branch but is not released yet.

Instead of downgrading SQLA, you can also simply solve it by adding inside your project websetup/__init__.py:

#Monkeypatch for compatibility with SQLA0.8

try:

    from sqlalchemy import exceptions

except ImportError:

    import sqlalchemy

    from sqlalchemy import exc

    sqlalchemy.exceptions = exc

hi maxim,

fyi, use http://turbogears.readthedocs.org/en/latest/index.html as the
documentation for future reference :)

Hi, Mengu!

Got it.

There were too many docs and instructions in google results, so I didn't know which one is right for today.

Thanks!

OMG!
"gearbox" instead of "paster"...
What does "-n -x" mean?
Where the hell "which template do You prefer"?

Well, it's OK, it's OK... I'll just calm down and start reading docs. The same shock was 2-3 years ago, when I quickstarted first project...

Peace and prosperity. See You soon. \\//,

Are you working with current stable or beta release? 

The beta release has replaced paster with gearbox, the options are the same, it just removed the interactive mode of quickstart.

List of changes between 2.3 and 2.2 is available at http://turbogears.readthedocs.org/en/rtfd2.3.0b1/cookbook/upgrading.html#from-2-2-to-2-3

To have a full list of options available in gearbox quickstart you can run "gearbox help quickstart".
