Hi Everyone,
congrats on the final release of 2.0. I've been waiting for that to happen and
after I saw the announcement today I immediately downloaded it.
I'm running a TG1 application (www.bunspace.com) which is rather large. So I
have many controllers for the different sections of the page (forum, blogs
etc.) and over 100 database tables.
I'd like to migrate the whole thing to TG2 - speed reasons are one of the
points, continuing long term support another and certainly I want to utilize
all the new features.
This all said: migrating a large app is expectedly painful. My most pressing
concern right now is reflection of tables, but the docs are sketchy at best
on this point and all I can find is that I really have to define 100+ classes
inside the init_model function of xxx.model.__init__.py
That will create a couple thousand lines of code in one method - not sure I
like that. Isn't there another way to reflect the tables in __init__.py and
define the classes to be mapped in other modules?
And no, typing up all the column definitions just to avoid reflection is not
really an option. I'll never use the auto generation of tables as I rather
deal with my database myself when it comes to schema changes. That's what
database modeling tools are for. Typing up every column, relation and
constraint is fine with little apps where the table constraints are few and
simple, but not when you have hundreds, if not thousands of constraints and
relations. For large, complex databases that kind of coding kills you over
time because it's not manageable - and IMHO database creation isn't the
concern of a web-framework. It's nice for a quick-start, but bad for
large-scale apps that have to share the database with other applications.
The second thing I've noticed is that there is no "registration" module
anymore. Did I miss that? For a "social networking" site like the one I run,
self-signup is crucial. Maybe someone wrote a replacement similar to the
functionality that was available in 1.0? Pointers would be very much
appreciated.
Other than that TG2 looks very promising right now. But I guess I'll be back
with more remarks or questions :-)
Thanks
Uwe
