Project Description
WHAT IS IT?
-----------

These templatetags is a hack making possible to insert 'content' in
some (maybe above the current or parent template) places.

More specifically, when we use these tags, there are some Nodes called
'containers' that are rendered after all other nodes are rendered, but placed
in it's right posistion. Using this hack, 'containers' may render
depending on variables in context that were generated by nodes placed anywhere in
template (maybe after it).

It's very useful in cases when you are reusing some template parts
very often. For example displaying comment list and comment submit form.
We write some template and put it into comments.html. Then every time
we need comments we just {% include "comments.html" %}.
But what if this part needs some js or css? Then we need to create
some comments-jscss.html and override some {% block head %}. IMHO this
is quite inconvenient.

Using this tool we can insert js and css into head
directly from comments.html

MOTIVATION
----------

1. Create convenient way to include media resources in head of HTML page.
2. Handle repetition of resource includes.
3. Make it possible to require resources from included templates.
4. Keep the order of resource includes from different places.

INSTALL
-------

1. (required) add 'insert_above' in INSTALLED_APPS in your settings.py

2. (optional) add these two lines of code somewhere in your project where
they will run for sure. For example in urls.py

~~~~
from django.template.loader import add_to_builtins
add_to_builtins('insert_above.templatetags.insert_tags')
~~~~

TAGS & FILTERS
--------------

1. {% insert_handler %}
2. {% container name %}
3. {% media_container name %}
4. {% insert_str container str %}
5. {% insert container %}{% endinsert %}
6. media_tag filter simply converts `ga.js` into `<script type="text/javascript" src="/static/ga.js"></script>`

RESTRICTIONS
------------

1. `{% container %}` or `{% media_container %}` tags must NOT be in other `{% block %}`.
2. `{% insert_handler %}` ought to be at ther very beginning of base template.

VARIABLES
---------

1. `IA_USE_MEDIA_PREFIX`, by default True
2. `IA_MEDIA_PREFIX`, if not set `STATIC_URL` is used, if not set `MEDIA_URL` is used, if not set '/media/' is used
3. `DEBUG`, if True logs how much time spent on rendering
4. `IA_JS_FORMAT`, by default `<script type="text/javascript" src="{URL}"></script>`
5. `IA_CSS_FORMAT`, by default `<link rel="stylesheet" href="{URL}" type="text/css"/>`
6. `IA_MEDIA_EXTENSION_FORMAT_MAP`, by default `{'css' : CSS_FORMAT, '.js' : JS_FORMAT}`

EXAMPLE
-------

Let's analyze an example.

base.html

~~~~{.html}
{% insert_handler %}
<html>
<head>
<script>
<script type="text/javascript" src="{{ MEDIA_URL }}js/jquery.min.js"></script>
{% media_container media %}

$(document).ready(function(){
{% container ready %}
});
</script>
</head>
<body>
{% block content %}
{% endblock %}
</body>
</html>
~~~~

Base template creating blocks and containers..

blog/base.html

~~~~{.html}
{% extends "base.html" %}

{% block content %}
{% insert_str media "js/mathjax.js" %}
{% block header %}{% endblock %}
{% block menu %}{% include "blog/menu.html" %}{% endblock %}
{% block text %}{% endblock %}
{% block footer %}{% endblock %}
{% endblock %}
~~~~

Extending content block. Requiring js/mathjax.js resource into 'media' container.

blog/menu.html

~~~~{.html}
{% insert_str media "js/animated.menu.js" %}
{% insert_str media "css/animated.menu.css" %}
{% insert ready %}
$('ul.menu').each(function(){
$(this).superanimation();
});
{% endinsert %}
<ul id="blog-menu" class="menu">
<li>link</li>
<li>link</li>
<li>link</li>
</ul>
~~~~

Requiring js/animated.menu.js and css/animated.menu.css into "media" container.
Inserting javascript code into "ready" container.

blog/post_detail.html

~~~~{.html}
{% extends "blog/base.html" %}

{% block header %}{{ title }}{% endblock %}

{% block text %}
{% insert_str media "js/mathjax.js" %}
{{ text }}
{% endblock %}

{% block footer %}
<hr>
{% endblock %}
~~~~

Implementing blocks and requiring js/mathjax.js into media.


So if we render
Template('blog/post_detail.html').render(Context({'title': 'Hello', 'text': 'World'}))
we will get:

~~~~{.html}
<html>
<head>
<script>
<script type="text/javascript" src="/media/js/jquery.min.js"></script>
<script type="text/javascript" src="/media/js/mathjax.js"></script>
<script type="text/javascript" src="/media/js/animated.menu.js"></script>
<link rel="stylesheet" href="/media/css/animated.menu.css" type="text/css"/>

$(document).ready(function(){
$('ul.menu').each(function(){
$(this).superanimation();
});
});
</script>
</head>
<body>
Hello
<ul id="blog-menu" class="menu">
<li>link</li>
<li>link</li>
<li>link</li>
</ul>
World
<hr>
</body>
</html>
~~~~

What shall be noted?
-------------------

1. `js/mathjax.js` automatically becomes `<script type="text/javascript" src="/media/js/mathjax.js"></script>`
and `css/animated.menu.css` becomes `<link rel="stylesheet" href="/media/css/animated.menu.css" type="text/css"/>`
2. inserting from included template is possible
3. any text may be inserted to any container. Here we insert javascript code in `$(document).ready(function(){});`
4. `js/mathjax.js` was required twice, but included only once.
5. The order of included resources is kept.

FIXTURES
--------

### version 1.0.2

+ **fix MEDIA_URL setting**
if STATIC_URL is not set in settings, it's value is None by default in new versions of Django.
Now we check if STATIC_URL is None, then use MEDIA_URL

### version 1.0.4

+ added new tag `{% insert_form container form %}`
+ added new tag `{% insert_form container form.media %}`

## TODOs

1. testing
2. extending tags
3. resource bulking
