Simple yet helpful library for writing Django urls by an easy, short an intuitive way.

Why should I use DjUrl?

Django routing urls aren't easy to deal with, regular expressions can become a nightmare sometimes. Just imagine dealing with such routes in your django app:

from django.conf.urls import url
from core import BlogView, SinglePostView, SearchResultsView, ArchiveView

urlpatterns = [
	# => /blog/
	url(r'^blog/$', BlogView.as_view(), name="blog"),
	# => /blog/5
	url(r'^blog/(?P<post_id>[0-9]+)/$', SinglePostView.as_view(), name="singlepost"),
	# => /blog/search/sometitle
	url(r'^blog/search/(?P<search_query>[A-Za-z0-9_-]+)/$', SearchResultsView.as_view(), name="search"),
	# => /blog/archive/2017/02/12
	url(r'^blog/archive/(?P<date>[0-9]{4}-(0?([1-9])|10|11|12)-((0|1|2)?([1-9])|[1-3]0|31))/$',
		ArchiveView.as_view(), name="archive")
]

That's too much work and you lost me in those regex. With DjUrl this comes easy, you just need to express what you want, DjUrl will handle the regular expressions for you:

from djurl import url
from core import BlogView, SinglePostView, SearchResultsView, ArchiveView

urlpatterns = [
	url('/blog', BlogView, name="blog"),
	url('/blog/:id', SinglePostView, name="singlepost"),
	url('/blog/search/:query', SearchResultsView, name="search"),
	url('/blog/archive/:date', ArchiveView, name="archive")
]

No regex, just clean paths and param names. You can now pass the regex work to DjUrl and concentrate in the bussiness logic. It saves you a lot of time and code. You don't need to worry about the routes anymore. Note you don't need to call as_view in your CBV's. DjUrl does this for you as well.

Usage

Now you know what you should use DjUrl, It's time to learn how to use it. DjUrl has a list of known/default pattern that you can use in your routes, these are:

• id: A secuence of characters from 0 to 9. Ej: 1, 12, 454545, 8885500, 8
• pk: A primary key, it's like id but needed for Class Based Views.
• page: falls in the same category, but you'd use page for a better param name.
• slug: A simple string (alphanumeric characters).
• query: A search parameter. It allows some special characters that slug doesn't. Ex: hello%20word, don%27t_quote-me
• day: A number between 01,..., 31.
• month: A number between 01,...,12.
• year: A four digits number: 1998, 2017, 2018, 3015, 2020, 1406...
• date: An expression with year-month-day format: 2017-06-23, 1998-10-20, 1492-10-12
• filename: An expression with *.\w{2,4} format: index.js, detail.html, 'my_book.pdf', 'dfj358h-g9854-fn84n4.tmp'
• UUID: Universally unique identifier is a 128-bit number used to identify information in computer systems. Use a format as xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx. Ex: 123e4567-e89b-12d3-a456-426655440000

That means, wherever you put /:id you can use it in your view as param (named id).

url('post/:pk/comment/:id', myview, name="post_comment")

Your view:

def myview(request, pk, id):
	# Use `pk` (post's) and `id` (comment's)

But what if I have two or more id's, or two slugs? What if I wanted to use a custom name for my id's? - Ok, you can use custom names if you end it with _ + the pattern type. - What?...

url('post/:post_pk/comment/:comment_id', myview, ...)
# ...
def myview(request, post_pk, comment_id):
	# `post_pk` is parsed as a :pk and `comment_id` like an :id

Yeah, it sounds good!, but... What if I wanted to use my own patterns? - Easy, any world in the path is of type :slug by default, but if you need a custom pattern you can register many as you want:

from djurl import url, register_pattern
register_pattern('hash', '[a-f0-9]{9}')
# parsed as slug
url('/:user', myUserView),
# custom pattern
url('/:hash', myview),
