Using Url_helper to simplify the URL configuration tutorial for the Django framework in Python

Django URLs are configured with regular expressions, though powerful and widely criticized. Opponents argue that Django's URL configuration is too cumbersome and does not support the default routing feature.

I think it is OK, just if feel uncomfortable, why not their own small hack, anyway, just a few lines of code.

In this context, I've made this url_helper, the use of Url_helper simplifies the configuration and implementation of default routes for URLs. The so-called url_helper in fact only url_helper.py a file, use when only want to import.

For specific use of url_helper, please refer to specific examples:

Url_helper Download/Example

Here is a simple explanation of how to use the method.
Default route for URLs

From Url_helper Import Execute, url_import views urlpatterns + = Patterns ("',  url (r ' ^ (? P
 
  
   
  . *) '
 , execute, {' Views ': views})
  

Add the following configuration in urls.py, where views are the views module that needs to be routed. The rules for URLs are/action/param1/param2/.../.

For example:

#/edit/4/def edit (Request, n= "id"):  html = "" "Edit object:%s" ""% n  return HttpResponse (HTML)

The action that is used by default when no action is specified is index.
Provides function Url_ simplifies URL configuration

Modelled on Ror's approach, the parameters are identified with ":".

For example:

#url_ (R '/space/:username/:tag/', views.url_), #/space/vicalloy/just/def url_ (request, username, tag):  
Tag:%s "" "% (username, tag)  return HttpResponse (HTML)

Complete code for Url_helper

As I said earlier, the code is very small. However, some extensions should be made in practical applications.

#!/usr/bin/env python#-*-coding:utf-8-*-from Django import httpfrom django.conf.urls.defaults import Urlimport re def Execute (Request, URLs, views): "" "  URLs [methodname/]param1/param2/.../  methodName Default index"  ]  def get_method (views, methodName):    try:      return GetAttr (views, methodName)    except Exception, E:      return None  method = None  params = [E for E in Urls.split ("/") if E]  params.reverse ()  if params:
  method = Get_method (views, Params.pop ())  if not method:    method = Get_method (views, ' index ')  if not Method:    raise HTTP. Http404 (' The requested admin page does not exist. ')  Return method (Request, *params) def url_ (*args,**dic):  regex = args[0]  if regex[0] = = "/":    regex = regex[1 :]  regex = ' ^ ' + regex  regex = regex + ' $ '  regex = Re.sub (": [^/]+],      Lambda matchobj:" (? p<%s>[^/]+) "% matchobj.group (0) [1:],      regex)  return URL (regex, *args[1:], **dic)
