Django Dynamic Template Loader ============================== There are times when you would like to use a different template based on the value of a HTTP request header. For example, different domain names, different browser types, or even the referring page. The dynamic template loader allows you to specify a separate list of directories in which Django should look for templates, based on a value in the request header. Installing ========== 1. Install ``dynamicloader`` in your Python path. 2. Add ``'dynamicloader.middleware.RequestMiddleware',`` into your ``MIDDLEWARE_CLASSES`` setting. 3. Add ``'dynamicloader.loader.load_template_source',`` at the *top* of your ``TEMPLATE_LOADERS`` setting. 4. Create a new setting, ``DYN_TEMPLATE_MAP``, in the following format:: DYN_TEMPLATE_MAP = { 'HTTP_HEADER1': { re.compile('value1'): ('/path/to/directory','/path/to/directory2',), re.compile('value2'): ('/path/to/directory3',) }, 'HTTP_HEADER2': { re.compile('value1'): ('/path/to/directory4',) } } Template Map Examples ===================== Domain Name Differences *********************** This example allows the override of certain templates based on the domain name or subdomain. In this setup, Django will look in ``/path/to/directory`` first if the ``HTTP_HOST`` includes the value ``www2``. :: DYN_TEMPLATE_MAP = { 'HTTP_HOST': { re.compile('www2'): ('/path/to/directory',), }, } Browser Differences ******************* This example allows the delivery of different templates (or just specific ones) based on the user's browser. :: DYN_TEMPLATE_MAP = { 'HTTP_USER_AGENT': { re.compile('iPhone|iPod'): ('/path/to/directory',), }, } Query String Differences ************************ This example checks the query string to decide which template to use based on a query string (the stuff after a '?' in a URL). :: DYN_TEMPLATE_MAP = { 'QUERY_STRING': { re.compile('imreallycool=1'): ('/path/to/directory',), }, }
