Django style multiple apps with web.py not working

问题

I run the example in the tutorial Django style multiple apps with web.py, but it does not working. The following is error message:

Traceback (most recent call last):
  File "run.py", line 11, in <module>
    delegate.run(mapping)
  File "/home/siongui/dev/test/delegate.py", line 31, in run
    web.run(handler, {})
AttributeError: 'module' object has no attribute 'run'

My web.py version is 0.37. Is there any idea on how to fix this? Thanks. (subapp is not a option for me.)

回答1:

There is some addition for the application module in 0.3 (http://webpy.org/docs/0.3/)

Applications. How to map urls to python code paths.
- Basic app. Map regexes to classes.
- Auto app. Have webpy keep track of the urls based on class name.
- Subdir app. Host multiple apps based on the sub-directory.
- Subdomain app. Host multiple apps based on the subdomain.

Following this cookbook should get things to work.

It's even easier than the example provided at webpy.org.

Updating that Django style multiple apps example:

Keep wiki.py, and blog.py as specified in the example
don't bother with delegate.py hack: it's no longer needed.

change run.py to:

"""run.py"""
import web
import wiki
import blog

urls = ("/blog", blog.app_blog,
        "/wiki", wiki.app_wiki,
        "/(.*)", "index")

class index:
    def GET(self, path):
        return "other: " + path

app = web.application(urls, locals())

if __name__ == "__main__":
    app.run()

The key change is the urls specified in run.py. If the second item is a string ("index" in the above example) then web.py expects that to be a class to handle the matching url ("/(.*)" in the example). This is the way webpy normally works.

However, if the second item is type application (blog.app_blog, for example), then the matching url (/blog) isn't a regex, it's a prefix & all incoming requests matching that prefix are handed to the related application (and the prefix is removed from the incoming request).
