suppose I have this url
url(r'^delete_group/(\w+)/', 'delete_group_view',name='delete_group')
In template
{%url 'delete_group' 'mwas'%} works but when I use
{%url 'delete_group' 'mwas 45'%} is not working. Any way to modify the url to accept both mwas and mwas 45
The issue might be your regex. The URL example you're showing has a space in it. \w won't match spaces. Try this instead: r'^delete_group/([\w\s]+)/ which allows either words or spaces in multiples.
However, know that spaces are not valid in URLs and will likely get converted to %20 or something similar. A best practice is to use hyphens where you would put a space.
I'd also point you at this answer to a similar question.

I have data from two URLS that I need to combine using REGEX
/online-teaching
/online-teaching?fbclid
I have /(online-teaching)|(online teaching)
I can't figure out how to include the url with the ? and the one without.
Thanks!
How about something as simple as:
online-teaching(?:.+)?
Regex demo
Match online-teaching and anything that follows, if it exists (might need to constraint for specific characters instead of matching all with . to have a valid URL, but I'll leave that up to you).
I need to pass tokens like b'//x0eaa#abc.com//x00//xf0//x7f//xff//xff//xfd//x00' in my Django Url pattern. I am not able to find matching regex for that resulting Page not found error.
My url will be like /api/users/0/"b'//x0eaa#abc.com//x00//xf0//x7f//xff//xff//xfd//x00'"/
I have tried with following regex
url(r'^api/users/(?P<username>[\w\-]+)/(?P<paging_state>[\w.%+-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4})/$', views.getUserPagination),
Please pass the token in request header or body and then use accordingly in your view.
Considering there are some static predictable elements in your url like -
api/users/
/" before b
"/ at the end after '
So I can see the url in either of the 2 ways below. Regex's mentioned accordingly:
api/users/(set of words, digits or hyphens)/"(any character except newline)"/
REGEX: ^api\/users\/([\w\d\-]+)\/"(.*)"\/$
URL: url(r'^api\/users\/([\w\d\-]+)\/"(.*)"\/$', views.getUserPagination),
api/users/(set of words, digits or hyphens)/"(one character-b)'//(any no. of words or digits)#(any no. of words or digits).(any no. of words or digits) (any no. of words, digits, front slashes)'"/
REGEX: ^api\/users\/([\w\d\-]+)\/"([a-g]'\/\/[\w\d]*#[\w\d]*.[\w\d]*[\/\w\d]*')"\/$
URL: url(r'^api\/users\/([\w\d\-]+)\/"([a-g]'\/\/[\w\d]*#[\w\d]*.[\w\d]*[\/\w\d]*')"\/$', views.getUserPagination),
You should be able to use either of the above two. There can be multiple ways to match the token part in your url. So unless it is a big security concern, you can do with the simplest approach as mentioned in point 1.
I have two URLs with the patterns:
1.http://localhost:9001/f/
2.http://localhost:9001/flight/
I have a site filter which redirects to the respective sites if the regex matches. I tried the following regex patterns for the 2 URLs above:
http?://localhost[^/]/f[^flight]/.*
http?://localhost[^/]/flight/.*
Both URLS are getting redirected to the first site, as both URLs are matched by the first regex.
I have tried http?://localhost[^/]/[f]/.* also for the 1st url. I am Unable to get what am i missing . I feel that this regex should not accept any thing other than "f", but it is allowing "flight" as well.
Please help me by pointing the mistake i have done.
Keep things simple:
.*/f(/[^/]*)?$
vs
.*/flight(/[^/]*)?$
Adding ? before $ makes the trailing slash with optional path term optional.
The first one will be caught with following regex;
/^http:[\/]{2}localhost:9001\/f[^light]$/
The other one will be disallowed and can be found with following regex
/^http:[\/]{2}localhost:9001\/flight\/$/
You regex has several issues: 1) p? means optional p (htt:// will match), 2) [^/] will only match : in your URLs since it will only capture 1 character (and you have a port number), 3) [^light] is a negated character class that means any character that is not l, i, g, h, or t.
So, if you want to only capture localhost URLs, you'd better use this regex for the 1st site:
http://localhost[^/]*/f/.*
And this one for the second
http://localhost[^/]*/flight/.*
Please also bear in mind that depending on where you use the regexps, your actual input may or may not include either the protocol.
These should work for you:
http[s]{0,1}:\/\/localhost:[0-9]{4}\/f\/
http[s]{0,1}:\/\/localhost:[0-9]{4}\/flight\/

I want to filter out all URL's that contain certain words, for example:
I have a URL that looks like this:
www.google.com/&SaveThis=true&SaveType=VeryFast&Page=0
And sometimes the 'Save Type' might change to slow or something. So what I want to do is show all URL's that have the 'SaveType=VeryFast' sometimes this can be in the middle of a very long URL.
I tried this:
.*SaveType=VeryFast.*
But it didn't work!
Thanks
From Tip #4 on this page, it looks like you don't need the .* on either end. That is, without the ^ and $ anchors, using SaveType=VeryFast should match any URL that contains those exact characters. It does look like word boundary anchors (\b) are not supported, so you will likely also match any URL that contains e.g. OtherSaveType=VeryFast or SaveType=VeryFastly
Otherwise, I don't see anything wrong with your expression... (?)
I'm trying to pass a 'string' argument to a view with a url.
The urls.py goes
('^add/(?P<string>\w+)', add ),
I'm having problems with strings including punctuation, newlines, spaces and so on.
I think I have to change the \w+ into something else.
Basically the string will be something copied by the user from a text of his choice, and I don't want to change it. I want to accept any character and special character so that the view acts exactly on what the user has copied.
How can I change it?
Thanks!
Notice that you can use only strings that can be understood as a proper URLs, it is not good idea to pass any string as url.
I use this regex to allow strings values in my urls:
(?P<string>[\w\-]+)
This allows to have 'slugs; in your url (like: 'this-is-my_slug')
Well, first off, there are a lot of characters that aren't allowed in URLs. Think ? and spaces for starters. Django will probably prevent these from being passed to your view no matter what you do.
Second, you want to read up on the re module. It is what sets the syntax for those URL matches. \w means any upper or lowercase letter, digit, or _ (basically, identifier characters, except it doesn't disallow a leading digit).
The right way to pass a string to a URL is as a form parameter (i.e. after a ?paramName= in the URL, and with special characters escaped, such as spaces changed to +).
