Django similar url pattern issue - django

I am working on a products comparison module and have url patterns like below:
path('comparison/<slug:slug1>-vs-<slug:slug2>/', views.compare_two_products, name="compare_two_products"),
path('comparison/<slug:slug1>-vs-<slug:slug2>-vs-<slug:slug3>/', views.compare_three_products, name="compare_three_products"),
The issue is that Django (3.2.6) always matches the first pattern and returns 404 when I try to access the second pattern. However if I comment out the first pattern, then it matches the third pattern just fine. I want to get both the patterns working in the format slug-vs-slug-vs-slug. Any suggestions on what I might be doing wrong ?
Thanks in advance.

Just change the order or URLs, like
path('comparison/<slug:slug1>-vs-<slug:slug2>-vs-<slug:slug3>/', views.compare_three_products, name="compare_three_products"),
path('comparison/<slug:slug1>-vs-<slug:slug2>/', views.compare_two_products, name="compare_two_products"),
that should work

How to fix regex url pattern

I need to fix my url pattern:
/^((http(s)?(\:\/\/)){1}(www\.)?([\w\-\.\/])*(\.[a-zA-Z]{2,4}\/?)[^\\\/#?])[^\s\b\n|]*[^\.,;:\?\!\#\^\$ -]/
I thought this regex was ok, but it is not working for urls like: https://xx.xx (without www). 'www' should be optional ((www.)?). Where is the bug?
The problem is not in the (www\.)? part but that parts after that.
Take a look at the [^\\\/#?] and the [^\.,;:\?\!\#\^\$ -] parts.
So a valid URL would be https://xx.xx plus none of \/#? plus none of .,;:?!#^$_- making the url valid if you add those, for example https://xx.xx11.
I do advice you to not try to create your own regex because you are missing a lot!
For example, tlds like .amsterdam are valid. And why are you capturing so many groups?

Analytics - Match URL with Parameters

I am having difficulties registering this URL as a goal. It is the final URL.
https://foo.com/Home/Search?Message=Success&show=True
I have tried matching the exact URL, but that doesn't work. I've tried various regEx patterns, but I don't know how to match a specific parameter/value.
Any help would be very much appreciated.
Thank you.
To match exactly this URL your regex should be like :
https:\/\/foo.com\/Home\/Search\?Message=Success&show=True

WordPress URL Rewrite unable to get second matches

My URL is http://example.com/locate/ny/2
in functions, I use below code
$wp_rewrite->add_rule('locate/([^/]+)','index.php?page_id=294&cs=$matches[1]','top');
I got URL like this http://example.com/locate/ny I got this working, but i want to add a pagination after ny like ny?cpaged=3 and rewrite to ny/3
but what is the regexp for index.php?page_id=294&cs=$matches[1]&cpaged=$matches[2] from url http://example.com/locate/ny/2
You need to add another capturing group within the regex that just picks out the digits from the url. Assuming your url structure isn't going to change this regex should work.
$wp_rewrite->add_rule('locate\/([^\/]+)\/(\d*)','index.php?page_id=294&cs=$matches[1]&cpaged=$matches[2]','top');

Why my Django URL doesn't grab the right way?

I've a problem with django url, when I go to:
/cars/my_town/my_office/
It's ok and view run as expected, town="my_town" and office_name="my_office".
When I go to:
/car/my_town/my_office/my_var1/
I get an error.
When I print the vars in my views I get:
town :"my_town/my_office" and office_name:"my_var1"
My view looks like this:
def ListingCars(request,town,office_name,var1=None) :
My urls:
url(r'^cars/(?P<town>[\w|\W ]+)/(?P<office_name>[\w|\W ]+)/$', web_public_views.ListingCars, name='listingvo_cars'),
url(r'^cars/(?P<town>[\w|\W ]+)/(?P<office_name>[\w|\W ]+)/(?P<var1>[\w|\W ]+)/$', web_public_views.ListingCars, name='listingvo_cars_var1'),
SOLVE ... it wasn't a resolverurl problem, but a myfault problem ;) i didn't see a "รง" on my tags name url... that cause the problem... thx for help i clean up my regex and sorry
\W is not word, which will match a slash, you can most likely just omit that and use \w, although its not clear what your url's should match, if it is slugs then its most likely that you need [\w-]+
^cars/(?P<town>[\w-]+)/(?P<office_name>[\w-]+)/$
^cars/(?P<town>[\w-]+)/(?P<office_name>[\w-]+)/(?P<var1>[\w-]+)/$
What is actually happening is your first regex is matching your url so it never uses the second one, so most likely you could also fix this by switching the order of these urls so the second is first but I wouldn't recommend this.

How do I match the question mark character in a Django URL?

In my Django application, I have a URL I would like to match which looks a little like this:
/mydjangoapp/?parameter1=hello&parameter2=world
The problem here is the '?' character being a reserved regex character.
I have tried a number of ways to match this... This was my first attempt:
(r'^pbanalytics/log/\?parameter1=(?P<parameter1>[\w0-9-]+)&parameter2=(?P<parameter2>[\w0-9-]+), 'mydjangoapp.myFunction')
This was my second attempt:
(r'^pbanalytics/log/\\?parameter1=(?P<parameter1>[\w0-9-]+)&parameter2=(?P<parameter2>[\w0-9-]+), 'mydjangoapp.myFunction')
but still no luck!
Does anyone know how I might match a '?' exactly in a Django URL?
Don't. You shouldn't match query string with URL Dispatcher.
You can access all values using request.GET dictionary.
urls
(r'^pbanalytics/log/$', 'mydjangoapp.myFunction')
function
def myFunction(request)
param1 = request.GET.get('param1')
Django's URL patterns only match the path component of a URL. You're trying to match on the querystring as well, this is why you're having trouble. Your first regex does what you wanted, except that you should only ever be matching the path component.
In your view you can access the querystring via request.GET
The ? character is a reserved symbol in regex, yes. Your first attempt looks like proper escaping of it.
However, ? in a URL is also the end of the path and the beginning of the query part (like this: protocol://host/path/?query#hash.
Django's URL dispatcher doesn't let you dispatch URLs based on the query part, AFAIK.
My suggestion would be writing a django view that does the dispatching based on the request.GET parameter to your view function.
The way to do what the original question was i.e. catch-all in URL dispatch var...
url(r'^mens/(?P<pl_slug>.+)/$', 'main.views.mens',),
or
url(r'^mens/(?P<pl_slug>\?+)/$', 'main.views.mens',),
As far as why this is needed, GET URL's don't exactly provide good "permalinks" or good presentation in general for customers and to clients.
Clients often times request the url be formatted i.e.
www.example-clothing-site.com/mens/tops/shirts/t-shirts/Big_Brown_Shirt3XL
this is a far more readable interface for the end-user and provides a better overall presentation for the client.
