Adding css/js files to the home site in the admin's panel django

I am trying to add a simple script to my admin's panel in django. I am following this example from the doc, which works when I do this:
class ArticleAdmin(admin.ModelAdmin):
class Media:
js = ("my_code.js",)
admin.site.register(Article, ArticleAdmin)
my_code.js (which lives in STATICFILES_DIRS) gets executed when I open the "Article" link in the admin's panel (so this would be the example url: localhost:8000/admin/news/article/)
However, I want it to be executed in the home site, as in right after I login to the admin's panel (this would be the url:localhost:8000/admin/) . Where do I have to insert the class Media then?

Are you trying to make your custom javascript appear on all admin pages? Then the best thing to do is to override the default admin templatte.
Look in your django installation and find django/contrib/admin/templates/admin/base.html make a copy of it in templates/admin in your project folder. Then simply add the following to the html.
<script scr="my_code.js" type="text/javascript"></script>
Then the js will be available on all admin pages.

I found another way which is overriding instead of replacing as explained in here.
If you place the file base.html into templates/admin:
{% extends "admin/base.html" %}
{% load static %}
{% block footer %}
{{ block.super }}
<script type="text/javascript" src="{% static 'my_code.js' %}"></script>
{% endblock %}
This will insert the script after the footer in the at localhost:8000/admin/.
Here I am "overriding" the base.html. But since I am using .super (explained here) it adds the script after the footer tag.

Pelican Archives Not Displaying

How do you enable an archives tab on a pelican powered blog?
I see from the docs that it is a direct template by default, but it isn't showing up on my blog. Is there some additional field to enable it? I couldn't find any mention of it in the docs or tutorials, so I'm assuming I've missed something obvious.

Not sure if you ever resolved this; I was having the same issue as you with pelican's bootstrap3 theme. For some reason, setting a value for YEAR_ARCHIVE_SAVE_AS was not working.
After looking at the theme's base.html file, I got it working by adding the following to pelicanconf.py:
ARCHIVES_SAVE_AS = 'archives.html'
Lines 156-158 from my base.html file:
{% if ARCHIVES_SAVE_AS %}
<li><i class="fa fa-th-list"></i><span class="icon-label">{{ _('Archives') }}</span></li>
{% endif %}

Explain the code snippet in Django

I am pretty new to Django. I am fiddling with zinnia to customize it and setting it up with my own theme/template etc. The main content displayed in the default template is following:
{% for object in object_list %}
{% include object.content_template with object_content=object.html_preview continue_reading=1 %}
{% empty %}
I understand that include includes the template inside a page. But what I cannot comprehend is: how do I find the relevant template being rendered? What is content_template? Please help me in understanding this snippet.

The template name (content_template) is being fetched from the database. It is a property of the model ContentTemplateEntry and defaults to zinnia/_entry_detail.html.

Getting Site_ID in template Django

I have build a web site for a client which has a number of applications. Now he has a new URL registered which he wants to point to the same site, but he wants the look and feel changed. That's basically he wants a new home.html and base.html for the new web site. I can easily add the new site to settings and then change the view for the home page, to display a new home2.html.
However how do I do something like this as expressed in psuedo code in base.html
{% if site_id equals 1 %}
{% include "base1.html" %}
{% endif %}
{% if site_id equals 2 %}
{% include "base2.html" %}
{% endif %}
Any ideas. There are 100s of views on the site and nearly 50 models. I cannot recreate models, and mess around. This needs to be a quick fix.
Thanks in advance

You can create a context processor to automatically add site_id to the context: http://docs.djangoproject.com/en/dev/ref/templates/api/#writing-your-own-context-processors
But I would opt for a different solution. You can simply add an extra template directory per site so Django will try the templates specifically for that site first and fall back to the normal templates if they're not available.

To extend the idea of WoLph with the context processor, I would maybe even add the switching of the template to the context processor which would clean up your templates, as otherwise you may have to repeat the if clause quite often:
from django.contrib.sites.models import Site
def base_template(request):
site = Site.objects.get_current()
template = "base%s.html" % str(site.pk)
return {'BASE_TEMPLATE': template}
And in your template: {% include BASE_TEMPLATE %}
Looks nicer to me than the switching in the templates!

Another solution would be writing a Middleware to set ´request.site´ the current site id.

Overriding Django Admin's main page? - Django

I'm trying to add features to Django 1.2 admin's main page.
I've been playing with index.html, but features added to this page affect all app pages.
Any ideas on what template I'm supposed to use?
Thanks loads!!

You can use template hierarchy like:
index.html
...
{% block content %}
...
{% block mycontent %}My custom text{% endblock %}
...
{% endblock %}
app_index.html
...
{% block mycontent %}{% endblock %}
..

According to http://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-vs-replacing-an-admin-template you will want to override admin/app_index.html

I have done this by modifying the admin/index.html template. You may also need to modify admin/base_site.html (depending on what you want to do, exactly).
These templates are found in the django/contrib/admin/templates/admin folder in a Django installation.
Update: That's exactly what I've done, see the screenshot fragment below. The section marked in red is the section I added, via HTML in admin/index.html. However, you don't say which version of Django you're using - my example is from a 1.0 installation.
