abid@abid-webdev:~/Documents/GAE_projects$ python google_appengine/dev_appserver.py exe1.py/

ERROR

INFO 2013-10-29 08:27:57,104 module.py:608] default: "GET / HTTP/1.1" 500 - ERROR 2013-10-29 08:29:43,171 wsgi.py:262] Traceback (most recent call last): File "/home/abid/Documents/GAE_projects/google_appengine/google/appengine/runtime/wsgi.py", line 239, in Handle handler = _config_handle.add_wsgi_middleware(self._LoadHandler()) File "/home/abid/Documents/GAE_projects/google_appengine/google/appengine/runtime/wsgi.py", line 298, in _LoadHandler handler, path, err = LoadObject(self._handler) File "/home/abid/Documents/GAE_projects/google_appengine/google/appengine/runtime/wsgi.py", line 84, in LoadObject obj = import(path[0]) ImportError: No module named helloworld INFO 2013-10-29 08:29:43,191 module.py:608] default: "GET / HTTP/1.1" 500 - ERROR 2013-10-29 08:29:51,775 wsgi.py:262] Traceback (most recent call last): File "/home/abid/Documents/GAE_projects/google_appengine/google/appengine/runtime/wsgi.py", line 239, in Handle handler = _config_handle.add_wsgi_middleware(self._LoadHandler()) File "/home/abid/Documents/GAE_projects/google_appengine/google/appengine/runtime/wsgi.py", line 298, in _LoadHandler handler, path, err = LoadObject(self._handler) File "/home/abid/Documents/GAE_projects/google_appengine/google/appengine/runtime/wsgi.py", line 84, in LoadObject obj = import(path[0]) ImportError: No module named helloworld

1) ImportError: No module named helloworld -> i noticed this error

application: your-app-id version: 1 runtime: python27 api_version: 1 threadsafe: true

handlers: - url: /.*

script: helloworld.application>

2) on google URL -> Every request to a URL whose path matches the regular expression /.* (all URLs) should be handled by the application object in the helloworld module.

3) my directory structure

abid@abid-webdev:~/Documents/GAE_projects$ ls

exercise1
helloworld
google_appengine

Question:

how can i modify my app.yaml to work with my other projects e.g. exercise1?

thanks all for your help.

Let's take this from the top!

For your new project you will need to have this structure in the exercise1 directory:

Directory: exercise1
  File: app.yaml
  File: exercise1.py

In the app.yaml you'll need something like this:

application: your-app-id
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /.*
  script: exercise1.application

The line "script: exercise1.application" tells it which file to use (in this case exercise1.py) and the instance of a WSGI Handler to use (in this case application)

In exercise1.py you'll need something like this:

import webapp2


class HomePage(webapp2.RequestHandler):
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write('Hey Y'all!')

application = webapp2.WSGIApplication([
    ('/', HomePage),
], debug=True)

Here you can see application that we referred to in app.yaml.

Once you have this basic structure you need to start the dev appserver. The way you are doing it in the question is incorrect:

You need to run the dev_appserver with the directory "exercise1", not a python file.

Assuming that the Google App Engine sdk is still located at "~/Documents/GAE_projects/google_appengine" run the following command from the exercise1 directory:

python ~/Documents/GAE_projects/google_appengine/dev_appserver.py ./

This will start the dev_appserver.py script telling it to use the current directory (which is what the "./" means).

If you follow this, then you should be up and rolling!
