How To Add Blog Category Navbar Links - Django Blog #15

In this video I'll show you how to add a dropdown menu to the navbar with links to our Category Pages.

We'll use the Bootstrap Navbar code to create a dropdown menu with links to each of our Category pages. We'll also create a webpage with nothing but links to all of our category pages.

There is a trick with context_proccessors in django.
For this case just add context_proccessors.py file in the app directory. Inside write something like:

from .models import Category


def navbar_context(request):
return {'cat_menu': Category.objects.all(), }

And don't forget to add this proccessor do settings.py :
TEMPLATES = [
{
...
'OPTIONS': {
'context_processors': [
...


],
...
That will pass 'cat_menu' value to every view (or any other value that you will write inside navbar_context dict).

Nice django blog course btw, found a lot of cool django features for myself!

Is there any specific reason to do so? Because I faced some issues after slugifying from the previous video where after restarting the server, it would give me "the page does not exist" thing after navigating to an existing category.

The category main page doesn't show the category nav item, how can I fix that?

Thank you very much for this, as a poor person like my self who just want to learn and maybe get a job this is a blessing.

I want to put the navbar category in the category.html, but I can't figure it out.

[marcelotedescodemiranda]

I have a little problem

I made this code but when I go to the category the nav dropdown list don't appear

class
model = Post
template_name = 'article_details.html'

def get_context_data(self, *args, **kwargs):
cat_menu = Category.objects.all()
context = super(ArticleDetailView, self).get_context_data(*args, **kwargs)
context["cat_menu"] = cat_menu
return context

[ali_sadrian]

Now still if we add a new category, we have to restart the server
How do we fix that Sir?

How to use cat_menu dropdown menu in each category

[antonyjohn]

[joeyrayhall]

I tried for two hours to get this to work; the button shows up on the navbar but does not show the pulldown content... :(

[jameskulu]

Is there any other solution for not repeating that code for listing category items in navbar?

[jarvismillan]
