I would like to see if this could be done as a third-party project (allow "pluggable URLs" which could use any syntax). If not, then let's accept a patch to Django to support it. Over time, if there's some strong consensus about a particular third-party package, then we could bring it in to

One problem with this approach, to let the community decide on this type of feature, is the target audience of it. This is mainly a feature for beginners, and more experienced users are expected to switch over to using regexes directly to get the exact behavior they want. Beginners likely

Hi, Good to hear so much from you. Just want know more, could anyone also explain why at first Django chose to use regex instead of a simple URL routing, except for the flexibility? By the way, like you said, routing in flask (or should say Werkzeug?) is also converting the simple URLs into

There is third party module providing third party url function. Surlex [1] have been mentionned. But any third party solution will need to provide function compatible with django.conf.urls.url. Line 64 of django/urls/revolvers.py is get_resolver. This function return a RegexURLResolver, using is

So it looks to me that the consensus is that this IS in fact a good idea, to supply a simpler, regex-free method to define URL:s. It also seems that the best liked version is something that's similar to what flask uses: /articles///. I've never written a DEP before, but it sounds like a fun

Emil, Please count me in if you'd like to start a new DEP. I'm also very interested to take this new challenge. And maybe we should dive into the code of URL resolver part of Django before we actually kick off? Anyway, I myself as a experienced user also like this idea. But as Tim and Ludovic

This is actually an interesting concept, and wouldn't incur an overheard at runtime if simple_url translated in to full regex format at launch time (or on first request, which is when the urls get loaded if I recall correctly). I don't think this would get in the way of includes, and if it's

Thank you for your input, Jarek. Assuming I have an existing model, adding models.CharField(blank=True, max_length=150) to it, doesn't invoke the questioner on current master. Changing this field to models.CharField(max_length=150) doesn't call the questioner either. Looking at the

Hi Ares, Your suggestion, used in urls.py would translate to: from django.conf.urls import simple_url from . import views urlpatterns = [ simple_url('articles/2003/', views.special_case_2003), simple_url('articles//', views.year_archive), simple_url('articles///',

Hi Robert, Thanks for doing this load testing. More context would be useful to help us outside observers to understand the potentially different variables. Is redis running locally or are you using elasticache? Regards, Michael Manfre On Mon, Sep 12, 2016 at 9:41 PM Robert Roskam

Hi, I don't think that the 'including' URLs part forms a problem here. For the given example, it should be easily doable > from django.conf.urls import simple_url > from . import views > urlpatterns = [ > simple_url('articles/2003/', views.special_case_2003), >

Hi, Actually flask uses a style very similar to what you want. To my knowing, you must use this pattern for Django because it has the concept of *including * URLs. Routing in flask: @app.route('post/', methods=['GET']) def post_view(post_id=None): # do something to render the post

Hi Emil, There are projects like https://github.com/codysoyland/surlex which I like very much. In the end, whatever you can come up which translates to regex in the background would work just fine for django. I personally like what werkzeug does -- "stealing" that sounds like an idea too :D I
