Hi everyone,
First things first: is there a documented way to move a TG2
application from one TG2 development environment to another? Also,
when committing a TG2 project to a source-code repository, exactly
what parts of the tree generated by "paster quickstart" need to be
controlled?
Excruciating details follow:
I had a development machine crash, so I am attempting to recover a TG2
app (developed last spring) from a source-code repository. The code in
the repository includes all, and only, the code in the tree generated
by "paster quickstart", plus my hand-developed code in the same tree
(changes to project_dir/model/*.py, project_dir/templates/*, and
project_dir/controllers/root.py). In the new TG2 environment I
installed on a different machine, this app will not run, though it had
no external dependencies outside of the virtual TG2 environment.
I've included the stack trace below, but I don't think that the
particulars of it are important. I'm 99% sure the problem is that I'm
trying to move an app developed under one version of TG, into a
virtual environment with a slightly different version of TG installed;
and the project has generated code that depends on the exact TG
version. My real questions are, "How can I recover from this?" and
"How can I avoid getting into similar difficulties in the future?"
My approach, in the absence of a better idea, will be to start with a
new "paster quickstart" app, diff the new project against the old one,
and migrate only the code I wrote by hand. But I'd rather there be a
better idea :-/
I would appreciate any advice.
Thanks,
-- Joe
