Changing css styles from view in Django

Question

Sorry in advance if there is an obvious answer to this, I'm still learning the ropes with Django.

I'm creating a website which has 6 pre determined subjects (not stored in DB) english, civics, literature, language, history, bible

each subject is going to be associated with a unique color.

I've got a template for a subject.html page and a view that loads from the url appname/subject/subjectname

what I need to do is apply particular css to style the page according to the subject accessed. for example if the user goes to appname/subject/english I want the page to be "themed" to english.

I hope I've made myself clear, also I would like to know if there is a way I can add actual css code to the stylesheet and not have to change attributes one by one from the back-end.

thanks very much!

Answer 1

In templates you can use conditionals for add css, like this:

<div class="{% if subject=='civics' %}civic-class{% endif %}"></div>

For this, subject value should come from view. Now, for themed page, you could use the extends tag. Let's supose:

def your_view(request):
    subject  # Here you get the url subject, 'how' is up to you
    if subject == 'english'
        template_base = '/some/html/tenplate.html'
    elif subject == 'civis':
        template_base = '/some/other/template.html'
    ... # then you return 'template_base' variable to template

Then in template:

{% extends template_base %}  # at the top

Hope this helps, is the same logic if you use Class-Based views.
