How to Use url_helper to simplify the url configuration of Django framework in Python

This article describes how to use url_helper to simplify the url configuration of the Django framework in Python. For more information, see

Django URLs are configured using regular expressions, which are also widely criticized. Opponents think that django's url configuration is too cumbersome and does not support the default routing function.

I think it's okay, but if I feel uncomfortable, why isn't I just a little hack? It's just a few lines of code.

In this context, I have integrated the url_helper and use url_helper to simplify the configuration and implement the default url routing. The so-called url_helper actually only has a file named url_helper.py. You only need to import the file.

For the usage of url_helper, see the example below:

Url_helper download/Example

The following is a simple description of the usage method.

Default url route

?

1 2 3 4 5 6

From url_helper import execute, url _ Import views   Urlpatterns + = patterns ('', Url (R' ^ (? P <urls>. *) ', execute, {'view': views }), )

Add the following configuration in urls. py, where views is the View module for routing. The url rule is/action/param1/param2 /... /.

For example:

?

1 2 3 4 5

#/Edit/4/   Def edit (request, n = "id "): Html = "edit object: % s" % n Return HttpResponse (html)

When no action is specified, the default action is index.

Provide function url _ simplify url Configuration

Like ROR, the parameter is marked.

For example:

?

1 2 3 4 5 6

# Url _ (R'/space/: username/: tag/', views. url _), #/Space/vicalloy/just/   Def url _ (request, username, tag ): Html = "username: % s <br/> tag: % s" "% (username, tag) Return HttpResponse (html)

Complete url_helper code

As mentioned above, there are very few codes. However, some extensions are needed for practical applications.
