Routes and cherrypy

[Jeremy]

Hi

I'm currently trying to change a bit what my url look like.

I currently have url like :
http://www.naphtaline.net/projects/some_name/bug/10
http://www.naphtaline.net/logMeIn/some_name/bug/10

Which works very fine. But for various reasons,I'd like to use url
like that :
http://projects.naphtaline.net/some_name/bug/10
http://projects.naphtaline.net/some_name/logMeIn/bug/10

which would allow the user to find all the pages related to his own
project at http://projects.naphtaline.net/some_name

I was using that code :
d.connect('logMeIn', '/logMeIn/:project/:category/:idEntry',
controller=root, action='logMeIn', category='bug', idEntry=0)
d.connect('projects', '/projects/:project/:category/:idEntry',
controller=root, action='projects', category='bug', idEntry=0)

And I changed it for that :
d.connect('logMeIn', '/:project/logMeIn/:category/:idEntry',
controller=root, action='logMeIn', category='bug', idEntry=0)
d.connect('projects', '/:project/:category/:idEntry', controller=root,
action='projects', category='bug', idEntry=0)

The issue is that I could potentially have a project called "logMeIn"
and therefore there may be a conflict.
I went to #pylons to talk about Routes and they told me there should
be no issue since routes stops at the first url matched. I just have
to be careful about the order of the entries.

However, when I try the new code, I get this error from cherrypy, and
it does not want to start.

Any idea ?

The error is arising because cherrypy.checker is trying to do static
analysis of your code, but the Routes implementation denies that since
it depends on a runtime-only structure, a WSGI environ. You can either
add a fake wsgi_environ attribute to the cherrypy.request object in the
main thread:

cherrypy.request.wsgi_environ = {fake data}

...or turn off that check:

cherrypy.checker.check_static_paths = None

I must say, I have no idea of what a WSGI is.
Other than solving my issue, what are the consequences of turning of
the check ? (Giving fake data does not seem like a good idea for me)

None; the check is just something CherryPy does to help identify places in your code that _might_ not have been written correctly. Any of its warnings are safe to ignore if you think you know what you're doing.

I don't get any warning. And it runs smoothly.

thanks a lot !
