Django URL Match

Study site: official

The following is a personal excerpt:

1. Basic Matching

Urlpatterns = Patterns (",    url (r ' ^articles/2003/$ ', ' news.views.special_case_2003 '),    url (r ' ^articles/(\d{ 4})/$ ', ' news.views.year_archive '),    url (r ' ^articles/(\d{4})/(\d{2})/$ ', ' news.views.month_archive '),    URL (R ' ^articles/(\d{4})/(\d{2})/(\d+)/$ ', ' News.views.article_detail '),)

/articles/2005/03/ This matches the third URL, which is News.views.mouth_archive (2005, 03)

/articles/2003/03/03/ match 4th, i.e. news.views.article_detail (Request, ' 2003 ', ' the ', ') ' .

2. Keyword Matching

Urlpatterns = Patterns (',    url (r ' ^articles/2003/$ ', ' news.views.special_case_2003 '),    url (r ' ^articles/(? P<YEAR>\D{4})/$ ', ' news.views.year_archive '),    url (r ' ^articles/(? P<YEAR>\D{4})/(? P<MONTH>\D{2})/$ ', ' news.views.month_archive '),    url (r ' ^articles/(? P<YEAR>\D{4})/(? P<MONTH>\D{2})/(? P<DAY>\D{2})/$ ', ' News.views.article_detail '),)

/articles/2005/03/ is news.views.month_archive (request, year= ' 2005 ', month= ') , instead of the news.views.month_archive (Request, ' 2005 ', ' A ' ).

Is it possible to get all the URL parameters? Of course

3. Default value Matching

Urlpatterns = Patterns (',    url (r ' ^blog/$ ', ' blog.views.page '),    url (r ' ^blog/page (? p<num>\d+)/$ ', ' Blog.views.page '), # View (in blog/views.py) def page (Request, num= "1"):    # Output the Appropriate page of blog entries, according to Num.    ...

If the first match is reached, num defaults to 1.

4. Model

If:

Urlpatterns = Patterns (",    url (r ' ^articles/(\d{4})/$ ', ' news.views.year_archive '),    url (r ' ^articles/(\d{4} )/(\d{2})/$ ', ' news.views.month_archive '),    url (r ' ^articles/(\d{4})/(\d{2})/(\d+)/$ ', ' News.views.article_ Detail '),)

It can be replaced by:

Urlpatterns = Patterns (' news.views ',    url (r ' ^articles/(\d{4})/$ ', ' year_archive '),    url (r ' ^articles/(\d{4}) /(\d{2})/$ ', ' month_archive '),    url (r ' ^articles/(\d{4})/(\d{2})/(\d+)/$ ', ' Article_detail '),)

Note that the first parameter of the patterns changes

5. Multi-model

If:

Urlpatterns = Patterns (',    url (r ' ^$ ', ' Myapp.views.app_index '),    url (r ' ^ (? P<YEAR>\D{4})/(? P<MONTH>[A-Z]{3})/$ ', ' Myapp.views.month_display '),    url (r ' ^tag/(? p<tag>\w+)/$ ', ' Weblog.views.tag '),)

It can be replaced by:

Urlpatterns = Patterns (' myapp.views ',    url (r ' ^$ ', ' App_index '),    url (r ' ^ (? P<YEAR>\D{4})/(? P<MONTH>[A-Z]{3})/$ ', ' Month_display '), urlpatterns + = patterns (' weblog.views ',    url (r ' ^tag/(? p<tag>\w+)/$ ', ' tag '),

6.include

Urlpatterns = Patterns ("',    # ... snip    ... URL (r ' ^comments/', include (' Django.contrib.comments.urls ')),    URL (r ' ^community/', include (' Django_ Website.aggregator.urls '),    url (r ' ^contact/', include (' Django_website.contact.urls ')),    # ... snip ...)

The following usage can also be:

Extra_patterns = Patterns ("",    url (r ' ^reports/(? p<id>\d+)/$ ', ' Credit.views.report '),    url (r ' ^charge/$ ', ' Credit.views.charge '), Urlpatterns = Patterns (' ', url (r '    ^$ ', ' apps.main.views.homepage '),    url (r ' ^help/', include (' Apps.help.urls ')),    URL (r ' ^credit/ ', include (Extra_patterns)),)

Is this complicated?

Urlpatterns = Patterns (' wiki.views ',    url (r ' ^ (? p<page_slug>\w+)-(? p<page_id>\w+)/history/$ ', ' history '),    url (r ' ^ (? p<page_slug>\w+)-(? p<page_id>\w+)/edit/$ ', ' edit '),    url (r ' ^ (? p<page_slug>\w+)-(? p<page_id>\w+)/discuss/$ ', ' discuss '),    url (r ' ^ (? p<page_slug>\w+)-(? p<page_id>\w+)/permissions/$ ', ' permissions '),)

Replace it with the following:

Urlpatterns = Patterns ("",    url (r ' ^ (? p<page_slug>\w+)-(? p<page_id>\w+)/', Include (Patterns (' wiki.views ',        url (r ' ^history/$ ', ' history '),        url (r ' ^edit/$ ', ' Edit '),        url (r ' ^discuss/$ ', ' discuss '),        url (r ' ^permissions/$ ', ' permissions '),)))    

7. Additional Parameters

Urlpatterns = Patterns (' blog.views ',    url (r ' ^blog/(? P<YEAR>\D{4})/$ ', ' year_archive ', {' foo ': ' Bar '}),

/blog/2005/, i.e. blog.views.year_archive (request, year= ' 2005 ', foo= ' bar).
