more.whytool: find out what code was responsible for generating a response

more.whytool lets you create a tool that tells you what view code was responsible for handling a request.

To create such a tool you do the following, for instance in the main.py of your project:

from more.whytool import view_tool
from .someplace import SomeApp

def my_why_tool():
    SomeApp.commit()
    why_tool(SomeApp)

where SomeApp is the application you want to query, typically the root application of your project.

Now you need to hook it up in setup.py to you can have the tool available:

entry_points={
    'console_scripts': [
        'morewhytool = myproject.main:why_tool',
    ]
},

After you install your project, you should now have a morewhytool tool available. You can give it requests:

$ morewhytool /some/path
