Switched out sqlite3 libs in favour of SQLAlchemy v0.9, will gradually migrate dialects and scheme to be fully SQLAlchemy compliant for using there ORM with sessions instead of direct. Fixed getEpisode function to stop making unrequired scene number conversions on already converted data thats available now from cache.

"""CherryPy is a pythonic, object-oriented HTTP framework.
|
|
|
|
|
|
CherryPy consists of not one, but four separate API layers.
|
|
|
|
The APPLICATION LAYER is the simplest. CherryPy applications are written as
|
|
a tree of classes and methods, where each branch in the tree corresponds to
|
|
a branch in the URL path. Each method is a 'page handler', which receives
|
|
GET and POST params as keyword arguments, and returns or yields the (HTML)
|
|
body of the response. The special method name 'index' is used for paths
|
|
that end in a slash, and the special method name 'default' is used to
|
|
handle multiple paths via a single handler. This layer also includes:
|
|
|
|
* the 'exposed' attribute (and cherrypy.expose)
|
|
* cherrypy.quickstart()
|
|
* _cp_config attributes
|
|
* cherrypy.tools (including cherrypy.session)
|
|
* cherrypy.url()
|
|
|
|
The ENVIRONMENT LAYER is used by developers at all levels. It provides
|
|
information about the current request and response, plus the application
|
|
and server environment, via a (default) set of top-level objects:
|
|
|
|
* cherrypy.request
|
|
* cherrypy.response
|
|
* cherrypy.engine
|
|
* cherrypy.server
|
|
* cherrypy.tree
|
|
* cherrypy.config
|
|
* cherrypy.thread_data
|
|
* cherrypy.log
|
|
* cherrypy.HTTPError, NotFound, and HTTPRedirect
|
|
* cherrypy.lib
|
|
|
|
The EXTENSION LAYER allows advanced users to construct and share their own
|
|
plugins. It consists of:
|
|
|
|
* Hook API
|
|
* Tool API
|
|
* Toolbox API
|
|
* Dispatch API
|
|
* Config Namespace API
|
|
|
|
Finally, there is the CORE LAYER, which uses the core API's to construct
|
|
the default components which are available at higher layers. You can think
|
|
of the default components as the 'reference implementation' for CherryPy.
|
|
Megaframeworks (and advanced users) may replace the default components
|
|
with customized or extended components. The core API's are:
|
|
|
|
* Application API
|
|
* Engine API
|
|
* Request API
|
|
* Server API
|
|
* WSGI API
|
|
|
|
These API's are described in the `CherryPy specification <https://bitbucket.org/cherrypy/cherrypy/wiki/CherryPySpec>`_.

(cherrypy.dispatch.Dispatcher.dispatch_method_name).
|

|
|
Optional keyword argument: handler=(Object or Function)
|
|
|
|
Provides a _cp_dispatch function that pops off path segments into
|
|
cherrypy.request.params under the names specified. The dispatch
|
|
is then forwarded on to the next vpath element.
|
|
|
|
Note that any existing (and exposed) member function of the class that
|
|
popargs is applied to will override that value of the argument. For
|
|
instance, if you have a method named "list" on the class decorated with
|
|
popargs, then accessing "/list" will call that function instead of popping
|
|
it off as the requested parameter. This restriction applies to all
|
|
_cp_dispatch functions. The only way around this restriction is to create
|
|
a "blank class" whose only function is to provide _cp_dispatch.
|
|
|
|
If there are path elements after the arguments, or more arguments
|
|
are requested than are available in the vpath, then the 'handler'
|
|
keyword argument specifies the next object to handle the parameterized
|
|
request. If handler is not specified or is None, then self is used.
|
|
If handler is a function rather than an instance, then that function
|
|
will be called with the args specified and the return value from that
|
|
function used as the next object INSTEAD of adding the parameters to
|
|
cherrypy.request.args.
|
|
|
|
This decorator may be used in one of two ways:
|
|
|
|
As a class decorator:
|
|
@cherrypy.popargs('year', 'month', 'day')
|
|
class Blog:
|
|
def index(self, year=None, month=None, day=None):
|
|
#Process the parameters here; any url like
|
|
#/, /2009, /2009/12, or /2009/12/31
|
|
#will fill in the appropriate parameters.
|
|
|
|
def create(self):
|
|
#This link will still be available at /create. Defined functions
|
|
#take precedence over arguments.
|
|
|
|
Or as a member of a class:
|
|
class Blog:
|
|
_cp_dispatch = cherrypy.popargs('year', 'month', 'day')
|
|
#...
|
|
|
|
The handler argument may be used to mix arguments with built in functions.
|
|
For instance, the following setup allows different activities at the
|
|
day, month, and year level:
|
|
|
|
class DayHandler:
|
|
def index(self, year, month, day):
