## Description

django-coat is the media files handler for Django. Represented with {% coat %} template tag. Can add cache-aware marks and compile files (with sass and etc.).

## Installation

django-coat can be easily installed with easy_install/pip or from source code.

## Setup

Two simple steps:

  • Add coat to project's INSTALLED_APPS
  • Add from coat.settings import * to the project's settings file

## Usage

django-coat mainly consists of {% coat %} template tag. This tag accepts relative to MEDIA_URL filename and optional string of flags. Then it returns compiled (if required) version of requested file's filename with cache-aware tag. Tag is ?something suffix of file url. It can be created with different strategies that fits the most frequent use-cases.

Media file compiling is the action of processing source media files with external programs. This programs can compress, translate or do anything they what with source files. Results of this processing are stored into filesystem and can be served this web server.

Basic usage example:

{% load coat %}

<link rel="stylesheet" type="text/css" href="{% coat "style.css" "absolute" %}">

Assume that MEDIA_URL equals to /media/ then tag will produce:

<link rel="stylesheet" type="text/css" href="">

where 123456 is file's mtime.

Available flags:

  • no-tag - do not append cache-aware tag
  • absolute - force to produce absolute url

  • COAT_COMPILED_PATTERN (default: '_%(name)s.%(ext)s') - filename pattern for compiled media files

  • COAT_COMPILED_ROOT (default: None) - absolute path to directory where compiled files will be stored. If None MEDIA_ROOT is used.

  • COAT_COMPILED_URL (default: None) - base url for compiled media files. If None MEDIA_URL is used.

  • COAT_COMPILERS dict (default keys: 'sass') - where keys are source media files extensions and values are tuples with compiled files extension and processing command.

  • COAT_TAGGER (default: 'coat.taggers.mtime') - tagger function with filename as argument.

    Available taggers:

    • coat.taggers.mtime - returns file mtime
    • coat.taggers.md5 - returns file content md5 hash sum
    • coat.taggers.md5_cached - cached version of md5 tagger.
  • COAT_CACHE_PREFIX (default: 'coat_') - name prefix for tagger generated cache keys

  • COAT_CACHE_TIME (default: None) - timeout for cached taggers
