Can't find the error in my django project

Question

I am creating a booking website for hotels using Django, I used the booking api to get the hotels with its images and location highlights... I sent to the django template a list of dictionaries from the backend, each dict represents a hotel, now there is two apis request that I am using 1- To get all the hotels 2-To get the images and location highlights of the hotel based on its id that 1 will give me alongside other info like the name and address... (when a button is pressed)

I implemented a loop in the template that will fetch all the hotels from the list on the page and I used the id of the hotel to pass it to a url namespace in the template (Template.html) where I want to call a function (book_now) and pass the arguments below: id of the hotel, name of the hotel, address of the hotel.

Now what's happening is that when I choose certain destination like Berlin or Istanbul or Paris I get this error:

NoReverseMatch at /homepage/
Reverse for 'book_now' with keyword arguments '{'id_hotel': **'6140138'**, 'name': 'Vital Hotel Fulya Istanbul Sisli', 'add': 'FULYA MAH. MEHMETÇİK CAD. NO: 61 İÇ KAPI NO: 3 ŞİŞLİ/İSTANBUL '}' not found. 1 pattern(s) tried: ['homepage/Book_now/(?P<id_hotel>[^/]+)/(?P<name>[^/]+)/(?P<add>[^/]+)$']

If I choose Dubai , Madrid , Los Angeles everything is working normally I don't know why its not logic

and and If I run book_now function alone with the id 6140138 and the name of the respective hotel that is given in the error (Here its Vital Hotel Fulya..) I get the expected result in the terminal

I really don't know what's happening

Answer 1

In that case, the address section of the query is causing the issue I think. You may need to update your regex to include special characters like ÇŞİ

ie. (?:[A-Z]|[ŞİÇ])

or your regex could be more inclusive by accepting any character

ie. book_now\/{id_hotel}\/.*\/
