How To Slugify Category Page URLs - Django Blog #14

[@robh9184]

Im feeling rather sluggified after smashing through 14 Django tutorials.. 5 more to goo!! Learning lots here thanks mate!

[@Codemycom]

ha fun

[@pentestPY]

Just watched this slugify video.. awesome, learned we can slugify and just delete the space and replace it with hyphen.. This thing is cool

[@pooriyayousefi7914]

you are a legend ! you are covering every concept that a blog needs . I don't google anymore :)) I use your videos xD big ups

[@Codemycom]

I appreciate that!

[@saeedyaqoob5784]

Here is a solution to the case problem: Just add this to your Category model in models.py to override its existing save method. def save(self, *args, **kwargs): self.name = self.name.lower() return super(Category, self).save(*args, **kwargs) It will make sure every new entry/category is saved as lowercase in your database. You might have to remove the existing categories saved as title or uppercase. Hope this helps. @John Really helpful videos. Learning a lot from them. Keep up the good work.

Coding is working but newly added Car or Entertainment not working..your code works..but category lists show all lower case i dont like it what can i do?

[@thattrollagen]

For anyone having issues: Instead of: def CategoryView(request, cats): category_posts = Post.objects.filter(category=cats.replace('-', ' ')) return render(request, 'categories.html', {'cats':cats.title().replace('-', ' '), 'category_posts':category_posts}) Do: def CategoryView(request, cats): category_posts = Post.objects.filter(category=cats.title().replace('-', ' ')) return render(request, 'categories.html', {'cats':cats.title().replace('-', ' '), 'category_posts':category_posts})

[@michaeldiehl-citoli3792]

Thanks! This fixed my "This page is not valid." error.

[@maramsagheer3399]

nice tutorial. i ran into a small issue where the normal categories wouldnt work after adding the slugify so i fixed it like this in case anyone was wondering. {% if " " in category.name %} {{ post.category }} {% else %} {{ post.category }} {% endif %}

[@Ali_Alhajji]

Great tutorial! The way I would solve the space in the URL is adding a new field in the Category model for the URL. For example, "coding tutorial" category would have another field "coding-tutorial" and I would use that in the URL.

[@hariharanbalasubramanianpr4243]

SIr, When I try to slugify in the url its showing %20 instead of '-'. In my views.py under the categoryView I gave this def CategoryView(request, cats): category_post = Post.objects.filter(category = cats.replace('-', ' ')) return render(request, 'categories.html', {'cats':cats.title().replace('-', ' '), 'category_post':category_post}) What can be the mistake sir.. Thanks,

[@animalcompilations832]

the same with me, and if you try the url with '-' the title delete the space between words

[@smishra6378]

Can you show the code in your home.html? You need to modify the url link of post.category in home.html, like this- - {{ post.category }}

But in my browser, instead of white space, Am getting "coding%20tutorials"... Even before adding slugify in that href... After adding also, I get the same... Not getting - instead of space... Why?

[@eduardobranco3490]

Cheers from Portugal! One thing , when we add a new category and write the name capitalised, we are sent to the "Sorry this page does not exist..." We must have to write with no caps, maybe because of the '.title()' object. You are great, thanks a lot!

[@Codemycom]

Could be...play around with it and see.

[@joseparedes4260]

Filter using __iexact which takes all the arguments ignoring upper and lower case For example: Post.objects.filter(category__iexact=cats)

I found the solution: When i add new category first letters are big but when i add new category first letters are small, it works. Hey John, thanks for your videos, great resources... And i have a problem with slugify... I am using latest django and i did same codes with yours... def CategoryView(request, cats): category_posts = Post.objects.filter(category=cats.replace('-', ' ')) return render(request, 'categories.html', {'cats': cats.title().replace('-', ' '), 'category_posts':category_posts}) But i still have a sorry page doesnt exist. I also check typo errors but nothing :( Could you solve this?

[@samuellee1431]

What worked for me was in my views python file, I had to add .title() in my Post.objects.filter in the CategoryView function. Original: CategoryView(request, cats): category_posts = Post.objects.filter(category = cats.replace('-', ' ')) ....,etc. After: CategoryView(request,cats): category_posts = Post.objects.filter(category = cats.title().replace('-', ' ')

[@ogananfe]

Excellent tutorial💞👍 but i think we have a bug. What happens if someone happens to name a category "co-operative"? There would be no match in the module once we decide to replace all the "-" with spaces because we would be looking for co operative in the database. I feel like we should have used primary keys instead of category names in the urls.

[@sgtdypen]

categories will be listed in the dropdown , and user will select it not by entering in url.

I tried the same process but I am not able to slugify the categories with two words. The category/categry-name does not load the posts Please help thanks

[@omarmughrabi1419]

Thanks for the great tutorials, actually I am able to follow every concept explained in this series. But for this tutorial I am having a concern for applying slugify on spaces contained category and then replacing the dash later on with space for categories that might have dash already like "anti-bodies". Is there a way to have a user defined slugify character to be & or % or maybe both instead of -?! 😁

[@ashutoshrai323]

[@joeboyle732]

Just in case anyone else runs into a problem here, if your categories have upper case letters at any point then slugify will convert them to lower case and the filter may not pick them up

[@Codemycom]

That's easily changed...

[@open-source-is-the-answer]

@@Codemycom how do you do it the easiest way? should I replace Post.objects.filter... with some lambda expression to ignoring case when searching? or is it much simpler?

[@dennismartin5455]

What if your category has hyphens and spaces in it, such as, "Brother-In-Law Advice"?

[@lenterahitam6519]

How do you show the number of items in the model to the template, for example, the number of books in each category?

[@saidsaid-nn1qk]

After adding "slugify" and replace function, when I try to go onto categories other than coding, it redirects to "sorry page doesn't exist. Is it only happening to me or is it the same with your code?

[@Codemycom]

It's just you

[@DavidLejeune77]

Had the same error , check if you used capital letters somewhere in your category name

[@hamzazahir1884]

Does anyone knows how to stop the site from adding the SAME category name again which has already been added to the database? For example once the user adds a category named "cars" and the user enters the same category again instead of adding, It should tell the user that this category has already been included in database.

[@haack79]

if you just slugify the category when saving them you don't have to worry about adding slugify in all the other spots and then doing all that logic to replace - with ' ' except for title.

sure, always a million different ways to do anything
