Hello,
I had some difficulties to set up some "routes_onerror" files on GAE. It
worked perfectly on a local instance, but each time an HTTP exception was
raised, GAE issued a "file inaccessible" error (status 500).
The problem comes from the fact that static files are treated specially on
GAE and are by default not counted in the applicatin quota and not
accessible to the application. One solution is the to add
"application_readable: true" to the static url handler in the app.yaml
file. But doing this, all static files are counted in the quota.
We however can not put the error files outside of the static directory,
where web2py expect them.
So, my solution is :
In the routes.py put something like:
routes_onerror= (
('*/503', '/appname/static/_0.0.0/error_handlers/503.html'),
('*/404', '/appname/static/_0.0.0/error_handlers/404.html'),
('*/*', '/appname/static/_0.0.0/error_handlers/default_error.html'),
)
(suppress _0.0.0/ if you don't use static asset management).
And in the app.yaml:
- url: /(.+?)/static/_(\d+\.\d+\.\d+)\/error_handlers/(.+)
static_files: applications/\1/static/error_handlers/\3
upload: applications/(.+?)/static/error_handlers/(.+)
secure: optional
expiration: "365d"
application_readable: true
- url: /(.+?)/static/_(\d+\.\d+\.\d+)\/(?!error_handlers)(.+)
static_files: applications/\1/static/\3
upload: applications/(.+?)/static/(?!error_handlers)(.+)
secure: optional
expiration: "365d"
Note the use of (?!…) to prevent the regexp to match our error handlers
file.
If you don't use static asset management, the code would be :
- url: /(.+?)/static/error_handlers/(.+)
static_files: applications/\1/static/error_handlers/\2
upload: applications/(.+?)/static/error_handlers/(.+)
secure: optional
application_readable: true
- url: /(.+?)/static/(?!error_handlers)(.+)
static_files: applications/\1/static/\2
upload: applications/(.+?)/static/(?!error_handlers)(.+)
secure: optional
See
https://cloud.google.com/appengine/docs/python/config/appref#handlers_element
for documentation about "application_readable" parameter.
Hope this may help others.
