Total noob Q: how to specify subdirectories in app.yaml?

[King Skippus]

This is my very first day ever looking at App Engine. Oh, and
Python. And YAML. That being said, I'm running into a really stupid
problem that I just can't seem to get around.

I have some templates stored in an application directory called source/
templates. I'd like to be able to access them, so in my app.yaml
file, I put the following:

handlers:
- url: /css
static_dir: source/templates

- url: /.*
script: source/Main.py

When I try to pull up a file in that directory, though, I'm getting
the following error from my dev_appserver.py console:

Error encountered reading file "E:\Docs\Projects\myapp\source
emplates"

That spacing after the word source is a tab. Apparently, the source/
templates is being interpreted as source(tab)emplates. I've tried
various ways of escaping the /t, but to no avail. I'm running all of
this on Windows Vista x64.

How the heck do you create a static subdirectory that has a component
that starts with a t?

Grrr...

Have you tried the Python "raw string" syntax? In your .py file,
where you have ...

"E:\Docs\Projects\myapp\source\templates"

... change it to ...

r"E:\Docs\Projects\myapp\source\templates"

handlers:
- url: /css
static_dir: source/templates

- url: /.*
script: source/Main.py

Did you try to put Main.py at the root ?
- url: /.*
script: /Main.py

because "source" is in the static_dir too. There is maybe an issue
with it.

I'm not completely sure, but if it's a string the typical solution
would be to escape the slash like so:

"E:\Docs\Projects\myapp\source\\templates"

But I'm mostly a PHP guy and that's how it would work in PHP, though
I'm really sure it should work the same way in Python. Let me know how
it goes.

I think the problem is that he has nothing of the sort in any .py
file; it's in app.yaml.

It sounds like a bug in the Windows version; the /'s are being
converted to \'s without escaping them.

I was able to reproduce his problem using the Windows version of
dev_appserver.py.

I suspect this section, starting at line 2393 in tools/
dev_appserver.py

regex = url_map.url
path = url_map.GetHandler()
if handler_type == appinfo.STATIC_DIR:
if regex[-1] == r'/':
regex = regex[:-1]
if path[-1] == os.path.sep:
path = path[:-1]
regex = '/'.join((re.escape(regex), '(.*)'))
if os.path.sep == '\\':
backref = r'\\1'
else:
backref = r'\1'
path = os.path.normpath(path) + os.path.sep + backref

url_matcher.AddURL(regex,
dispatcher,
path,
requires_login, admin_only)

TonyV,

I was able to reproduce your problem in a Windows environment. The
bug appears to be in the way the STATIC_DIR handler converts slashes
to backslashes. There is no such bug in the STATIC_FILES handler, so
there is a workaround:

Instead of ...

- url: /css
static_dir: source/templates

... use ...

- url:/css/(.*)
static_files: source/templates/\1
upload: source/templates/(.*)
