Description:
 def render_to(template=None, content_type=None):
 """ Decorator for Django views that sends returned dict to render_to_response function. Template name can be decorator parameter or TEMPLATE item in returned dictionary. RequestContext always added as context instance. If view doesn't return dict then decorator simply returns output. Parameters: - template: template name to use - content_type: content type to send in response headers Examples: # 1. Template name in decorator parameters @render_to('template.html') def foo(request):
 bar = Bar.object.all() return {'bar': bar} # equals to def foo(request):
 bar = Bar.object.all() return render_to_response('template.html', {'bar': bar}, context_instance=RequestContext(request)) # 2. Template name as TEMPLATE item value in return dictionary. if TEMPLATE is given then its value will have higher priority than render_to argument. @render_to() def foo(request, category):
 template_name = '%s.html' % category return {'bar': bar, 'TEMPLATE': template_name} #equals to def foo(request, category):
 template_name = '%s.html' % category return render_to_response(template_name, {'bar': bar}, context_instance=RequestContext(request)) """
