Still I need to log the ticket issue so we know what is happening (we will be watching for errors to show on the admin webapp), but we dont want the error to be like the HTML that is always show to the user.

I want to return a one of the following depending on where Im returning it (a page in the web app or a request of a service)

  • for the service
    • {"error":"see ticket xyz"}
  • for the HTML webpage
    • General error, return home "here".

Where exactly I need to put this file?

I have tried

error_message = '<html><body><h1>%s-------</h1></body></html>'
error_message_ticket = '''<html><body><h1>Internal error</h1>
     Ticket issued: <a href="/admin/default/ticket/%(ticket)s"
     target="_blank">%(ticket)s</a>------</body></html>'''

routes_onerror = [
  ('init/400', '/backend/default/index'),
  ('init/*', '/backend/default/index'),
  ('*/404', '/backend/default/index'),
  ('*/*', '/backend/error/report')
]



error_handler = dict(application='backend',
                     controller='error',
                     function='report')


Still no correct message displayed if I cause a 500 server error. Where do I activate it?

I mean, even debugging passes over the redirector inside web2py and see nothing on those variables causing normal behaviour on the branch on rewrite.py

if status >= 399 and THREAD_LOCAL.routes.routes_onerror:


so....

routes.py goes in the root /web2py folder. Be sure to restart the server or reload routes (via admin). Also, make sure you don't actually have an error somewhere in your error handling app.

I thought it was a per app configuration.

I mean, we have other web2py apps there, I dont want to modify the default behaviour of the other ones, only this "backend" app.

Well also now I got it (still not per app)... but the problem Im having is that I want to return a json, but Im getting the full HTML response  with a body and all that.

If I use 

error_handler = dict(application='backend',
                     controller='error',
                     function='report')

Nothing changes. So I have setup


routes_onerror = [
  ('init/400', '/backend/default/index'),
  ('init/*', '/backend/default/index'),
  ('*/404', '/backend/default/index'),
  ('*/*', '/backend/error/report')
]


I have as response this HTML instead of the json


<html><head><link rel="alternate stylesheet" type="text/css" href="resource://gre-resources/plaintext.css" ></head><body data-pinterest-extension-installed="ff1.37.9"><pre>{&amp;#x27;message&amp;#x27;: &amp;#x27;Error interno&amp;#x27;}</pre></body></html>

Are  you setting content type to json?  That came up recently in a thread.  You can (AIUI) either set just the header string and use response.json(), or use generic.json as a template example.

Well, the book says routes_onerror can specify a global mapping, an app mapping, an error code mapping, or app+err.
<URL:http://web2py.com/books/default/chapter/29/04/the-core#Routes-on-error>

Just above that, in the tail of the pattern-based router description, it talks about how to have the base routes.py direct to an app routes.py for handling the other URLs of a specific application.

Yes, it seems the documentation is way off regarding error_handler. As far as I can tell, the only time that does anything is when you request a non-existent application, in which case, it does a full HTTP redirect to the application specified in error_handler, with the name of the originally requested application in request.args(0). Given its functionality, it would be better named something like missing_app_handler.

Is it possible there is an error in the backend app itself?

In routes_onerror, you can specify both the app and the error code (or use wildcards for either).
