Decorator, written for views simplification. Will render dict, returned by view, as context for template, using RequestContext. Additionally you can override template, returning two-tuple (context's dict and template name) instead of just dict.

Usage:

@render_to('my/template.html')
def my_view(request, param):
    if param == 'something':
        return {'data': 'some_data'}
    else:
        return {'data': 'some_other_data'}, 'another/template.html'

def render_to(template):
    """
    Decorator for Django views that sends returned dict to render_to_response function
    with given template and RequestContext as context instance.

    If view doesn't return dict then decorator simply returns output.
    Additionally view can return two-tuple, which must contain dict as first
    element and string with template name as second. This string will
    override template name, given as parameter

    Parameters:

     - template: template name to use
    """
    def renderer(func):
        def wrapper(request, *args, **kw):
            output = func(request, *args, **kw)
            if isinstance(output, (list, tuple)):
                return render_to_response(output[1], output[0], RequestContext(request))
            elif isinstance(output, dict):
                return render_to_response(template, output, RequestContext(request))
            return output
        return wrapper
    return renderer

wonderful snippet, this should be in django.shortcuts

Make sure you include:

from django.shortcuts import render_to_response
from django.template import RequestContext

in your views.py.

Excellent simplification with this decorator!
