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'

"""
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
