I like a download list with all Files with the Category == 'download' in all available categories. (ManyToMany Field)

>>>from feincms.module.medialibrary.models import MediaFile, Category
>>>MediaFile.objects.filter(categories=1) #my download pk, these files I need
>>>Category.objects.all() # these categories I need

models.py: https://github.com/feincms/feincms/blob/master/feincms/module/medialibrary/models.py

it must be a mix from :

{% for category in category %}
<h1>{{ category }}</h1>
    {% for file in category.mediafile_set.all %}
        <li> {{ file }} </li>
    {% endfor %}
 {% endfor %}

but not all files, only the files with the category (or let's say Tag) 'download'.

and: 

{% regroup file by categories.all as media_list %}
<ul>
{% for categories in media_list %}
    <li>{{ categories.grouper }}
    <ul>
        {% for file in categories.list %}
          <li>{{ file }}</li>
        {% endfor %}
    </ul>
    </li>
{% endfor %}
</ul>

these files are good, but the categories are not in the right position and format.

I need a tree like this:

Category 1 # the Download category, all files

  • file 3
  • file 1
  • file 2

Category 2

  • file 3

Category 3

  • |_ SubCategory 3.1 (if chidren, next challenge)
    • file 2
  • file 3

my views.py this:

from feincms.module.medialibrary.models import MediaFile, Category

def medialistview(request):
    file = MediaFile.objects.filter(categories=1)
    category = Category.objects.all()   
    return render_to_response('media.html',{
        'file': file, 'category': category, 
    },context_instance=RequestContext(request))

I'm a beginner, maybe it is very easy...

You can use self referential template includes, and then just pass the categories variable in as the current children of each category as you iterate through..

Lets say this is: category_tree.html

{% regroup file by categories.all as media_list %}
<ul>
{% for category in media_list %}
    <li>{{ category.grouper }}
    {% include "category_tree.html" with categories=category.children %}
    <ul>
        {% for file in category.list %}
          <li>{{ file }}</li>
        {% endfor %}
    </ul>
    </li>
{% endfor %}
</ul>
