You don't need to change this path (and shouldn't) because it's where
TG's static files (Mochikit, etc...) live and some unexpected
behavior (like being unable to access TG's bundle Mochikit) might
happen.
Your app's static directory is already registered at config/app.cfg
so any access to {webroot}/static/ will map there.
To access anything there you should link to it like:
${tg.url("static/javascript/my.js")}
Remember to use tg.url so the full path gets computed correctly (just
in case your webroot isn't "/")
If you want to add another different path just add another block in
app.cfg (take the [/static] block as inspiration).
To make a reference to this path available to all templates without
needing to return it in every controller you can do this by adding a
variable provider:
from turbogears import url
def my_var_provider(d):
d.update(my_js_path = url("foo/bar/js"))
from turbogears.view import variable_providers
variable_providers.append(my_var_provider)
Now from your templates you can use ${std.my_js_path}/whatever.js.
Again, remember to send the path via the "url" function so it gets
computed correctly.
HTH,
Alberto
