def render_html(action, resource, content_type=None, status=None,
current_app=None):
"""
Render an appropriate HTML response for an action.
This is a generic renderer backend which produces HTML responses. It uses
the name of the resource and current action to generate a template name,
then renders the template with a `RequestContext`.
To retrieve the template name, the resource name is first turned from
CamelCase to lowercase_underscore_separated; if the class name ends in
`Resource`, this is first removed from the end. For example:
User => user
UserResource => user
NameXYZ => name_xyz
XYZName => xyz_name
You can optionally define a template path prefix on your `Resource` like
so:
class User(Resource):
template_path_prefix = 'auth/'
# ...
The template name is assembled from the template path prefix, the
re-formatted resource name, and the current action name. So, for a `User`
resource, with `template_path_prefix = 'auth/'`, and an action of `show`,
the template name would be:
auth/user/show.html
Finally, this is rendered using `django.shortcuts.render()`. The resource
is passed into the context as `self`, so that attribute assignments from
the action will be available in the template. This also uses
`RequestContext`, so configured context processors will also be available.
