django-precise-bbcode 1.0.6

A django BBCode integration..

Django-precise-bbcode is a Django application providing a way to create textual contents based on BBCodes.

BBCode is a special implementation of HTML. BBCode itself is similar in style to HTML, tags are enclosed in square brackets [ and ] rather than < and > and it offers greater control over what and how something is displayed.

This application includes a BBCode compiler aimed to render any BBCode content to HTML and allows the use of BBCodes tags in models, forms and admin forms. The BBCode parser comes with built-in tags (the default ones ; b, u, etc) and allows the use of smilies, custom BBCode placeholders and custom BBCode tags. These can be added in two different ways:

• Custom tags can be defined in the Django administration panel and stored into the database ; doing this allows any non-technical admin to add BBCode tags by defining the HTML replacement string associated with each tag

• Tags can also be manually registered to be used by the parser by defining a tag class aimed to render a given bbcode tag and its content to the corresponding HTML markup

Read more in the documentation (latest version).

Requirements

• python >= 2.7 (tested with version 2.7, 3.2, 3.3, 3.4)

• django >= 1.4.2 (tested with version 1.4.2, 1.5, 1.6, 1.7)

• PIL or Pillow (required for smiley tags)

• setuptools

Installation

Just run:

pip install django-precise-bbcode

Once installed you can configure your project to use django-precise-bbcode with the following steps.

Add precise_bbcode to INSTALLED_APPS in your project’s settings module:

INSTALLED_APPS = (
    # other apps
    'precise_bbcode',
)

Then install the models:

python manage.py syncdb

If you are using Django 1.6 or below, you should use South 1.0 in order to benefit from the migrations. This way you can use the migration command provided by South:

python manage.py migrate precise_bbcode

Usage

Rendering bbcodes

Django-precise-bbcode comes with a BBCode parser that allows you to transform a textual content containing BBCode tags to the corresponding HTML markup. To do this, simply import the get_parser shortcut and use the render method of the BBCode parser:

>>> from precise_bbcode import get_parser
>>> parser = get_parser()
>>> parser.render('[b]Hello [u]world![/u][/b]')
'<strong>Hello <u>world!</u></strong>'

It’s that easy!

As you may need to render bbcodes inside one of your Django template, this parser can be used as a template filter or as a template tag after loading bbcode_tags:

{% load bbcode_tags %}
{% bbcode entry.bbcode_content %}
{{ "[b]Write some bbcodes![/b]"|bbcode }}

The BBCode content included in the entry.bbcode_content field will be converted to HTML and displayed. The last statement will output <strong>Write some bbcodes!</strong>.

Storing bbcodes

While you can use the Django built-in models.TextField to add your BBCode contents to your models, a common need is to store both the BBCode content and the corresponding HTML markup in the database. To address this django-precise-bbcode provides a BBCodeTextField.

from django.db import models
from precise_bbcode.fields import BBCodeTextField

class Post(models.Model):
    content = BBCodeTextField()

This field will store both the BBCode content and the correspondign HTML markup. The HTML content of such a field can then be displayed in any template by using its rendered attribute:

{{ post.content.rendered }}

Head over to the documentation for all the details on how to use the BBCode parser and how to define custom BBcode tags, placeholders and smilies.
