I have the following urlpatterns:
url(r'^api/daily-means/$', views.daily_means.as_view(), name='daily_means'),
url(r'^api/daily-means/sites/(?P<url>\w+)/$', views.site_daily_means.as_view()),
url(r'^api/daily-means/pollutant/(?P<poll>\w+)$/', views.pollutant_daily_means.as_view()),
The first two work fine. The last one show work the same as the second one but it does not. Im not that great with regex and urlpatterns but I assume there is something with the second url pattern which is stopping the last one from running. Can anyone else see a reason for this?
Django will append the end slash if it is not provided. In your regex, you are matching without the end slash.
url(r'^api/daily-means/pollutant/(?P<poll>\w+)$/', views.pollutant_daily_means.as_view()),
The following URL pattern should work(after including the end slash as a part of URL match).
url(r'^api/daily-means/pollutant/(?P<poll>\w+)/$', views.pollutant_daily_means.as_view()),

I'm trying to do a regex to match just the second part of a URL and leave the rest behind
For example
https://example.com/first-part/second-part/third-part/?prop=2
result = https://example.com/alt/second-part/
How can I do this?
I'm able to match the first two parts but for when I use the "/" for match it picks the last / one, instead the one before.
I can go the simple way like this:
RewriteRule ^(.*)first-part\/(.+)\/(.*)\/(.*)$ https://example.com/alt/$2 [R=301,L]
The problem is that if the URL is like this:
https://example.com/first-part/second-part/
Result expected. https://example.com/alt/second-part/
It won't even match it
So I'm looking for a more generic alternative, that may match multiple scenarios giving the same result ultimately in the same format:
https://example.com/alt/second-part/
Just knowing how the first-part exactly is and not knowing how anything beyond the second-part will be formated.
Taking into account the recommendations of #Eraklon to avoid the greedy checks I've found out a solution:
RewriteRule ^first-part\/([^\/]+(\/)?)(.*) https://example.com/alt/$1 [R=301,L]
Can be checked here:
https://htaccess.madewithlove.be?share=8973fe68-f137-59a5-b27b-0cbbe3d842bc
It exactly matches the first-part with ^first-part/ and then in enters the group:
([^\/]+(\/)?)
That checks for 1 or more chars that are not a slash /. When it finds the first slash it can be the next section of the URL or the end of the URL.
Not sure if this is the best but the idea is that it matches just 1 pattern for $1 that includes both the end slash and not-slash for the second-part block of the URL.
I've not been able to remove the last bit from the url (the parameters ?parameter=a)
So the result with this form a URL like:
https://example.com/first-part/second-part/third-part/?parameter=a
Will be
https://example.com/alt/second-part/?parameter=a
Fortunately, the parameters are not too bad, but I would have preferred the full solution.
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');

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.
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\/

All of the examples I can find of urlpatterns for django sites have a separate entry for incoming urls that have no leading slash, or the root folder. Then they handle subfolders on each individual line. I don't understand why a simple
/?
regular expression doesn't permit these to be on one simple line.
Consider the following, let's call the Django project Baloney and the App name is Cheese. So in the project urls.py we have something like this to allow the apps urls.py to handle it's requests...
urlpatterns = patterns('',
(r'^cheese/', include('Baloney.Cheese.urls')),
)
then inside of the Cheese apps urls.py, I don't understand why this one simple line would not trigger as true for all incoming url subpaths, including a blank value...
urlpatterns = patterns('',
(r'^(?P<reqPath>.*)/?$', views.cheeseapp_views),
)
Instead, it matches the blank case, but not the case of a value present. So...
http://baloneysite.com/cheese/ --> MATCHES THE PATTERN
http://baloneysite.com/cheese/swiss --> DOES NOT MATCH
Basically I want to capture the reqPath variable to include whatever is there (even blank or '') but not including any trailing slash if there is one.
The urls are dynamic slugs pulled from the DB so I do all the matching up to content in my views and just need the url patterns to forward the values along. I know that the following works, but don't understand why this can't all be placed on one line with the /? regular expression before the ending $ sign.
(r'^$', views.cheeseapp_views, {'reqPath':''}),
(r'^(?P<reqPath>.*)/$', views.cheeseapp_views),
Appreciate any insights.
I just tried a similar sample and it worked as you wrote it. No need for /?, .* would match that anyway. What is the exact error you are getting? Maybe you have your view without the request parameter? I.e. views.cheeseapp_views should be something like:
def cheeseapp_views(request, reqPath):
...
Edit:
The pattern that you suggested catches the trailing slash into reqPath because * operator is greedy (take a look at docs.python.org/library/re.html). Try this instead:
(r'^(?P<reqPath>.*?)/?$', views.cheeseapp_views)
note it's .*? instead of .* to make it non-greedy.
