[Answered ]-Django Generic DetailView customization

To add content to your DetailView override the get_context_data method. For instance, if you add the following method to your ProjectDetailView class:

def get_context_data(self, **kwargs):
    context = super(ProjectDetailView, self).get_context_data(**kwargs)
    context['hello'] = "Hello, world"
    return context

you will have an extra context variable named hello in your template, so you would output it with {{ hello }}.

Hint: CBV Inspector is your friend when you deal with CBVs.

Update

OP wanted to pass the directory django is running from to his traverse_dir function. To do that, you can add the following to your settings.py (django 1.6 adds it by default):

import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))

Now, you can change your get_context_path method of ProjectDetailView like this:

from django.conf import settings

def get_context_data(self, **kwargs):
    context = super(ProjectDetailView, self).get_context_data(**kwargs)
    context['dirs'] = traverse_dir(settings.BASE_PATH)
    return context

Now you will have a dirs variable in your context which can be outputed using (for instance) a {% for %} loop.

Notice: I haven’t checked if traverse_dir is working as expected.

Update 2

It turns out the OP had a different question: How to display a folder hierarchy with django. What I’d do is create simple view (not DetailView) named traverse and add the following url patterns in my urls.py

url(r'^traverse/(.+)*', 'views.test.traverse', name='traverse' ),

Now, the traverse view could be implemented like this:

def traverse(request, segments=""):
    segments = segments.split(r'/')
    # segments is an array of the url paths
    # construct the path of the folder you want to view here
    # by concatenate settings.BASE_PATH with the url components

    # finally output the contents of the folder by creating links
    # which concatenate the segments with the contents of the folder
