Easy Way to Escape Django Template Variables

Question

For a new project we\'re writing documentation about the Django template system. We use Django for the documentation project itself too, so Django picks up all our exam

Answer 1

Here is an elegant way to solve to problem for Djano 1.4. It is a Django custom tag. Simply create a module verbatim_templatetag.py containing the following code:

"""
jQuery templates use constructs like:

    {{if condition}} print something{{/if}}

This, of course, completely screws up Django templates,
because Django thinks {{ and }} mean something.

Wrap {% verbatim %} and {% endverbatim %} around those
blocks of jQuery templates and this will try its best
to output the contents with no changes.
"""

from django import template

register = template.Library()


class VerbatimNode(template.Node):

    def __init__(self, text):
        self.text = text

    def render(self, context):
        return self.text


@register.tag
def verbatim(parser, token):
    text = []
    while 1:
        token = parser.tokens.pop(0)
        if token.contents == 'endverbatim':
            break
        if token.token_type == template.TOKEN_VAR:
            text.append('{{')
        elif token.token_type == template.TOKEN_BLOCK:
            text.append('{%')
        text.append(token.contents)
        if token.token_type == template.TOKEN_VAR:
            text.append('}}')
        elif token.token_type == template.TOKEN_BLOCK:
            text.append('%}')
    return VerbatimNode(''.join(text))

Then in your template: {% load verbatim_templatetag %}

Everything between {% verbatim %} and {% endverbatim %} will not be parsed.
