templeton Description

Basic framework for rapid creation of web tools Templeton is a Python module, script, and support files intended for rapid development of simple web applications. It's basically a package around web.py which suggests a common layout and organization for web apps.The templeton scriptUsage:templeton install < www-data-dir >Copies support files (JS, CSS) into a "templeton" directory in < www-data-dir >. The latter should be the root of the web site that will serve templeton apps, since the template HTML file loads JS and CSS from /templeton.templeton init < appname >Creates a directory named with "html" and "server" directories containing templates. You should be able to serve up your default app by doing cd < appname >/server python server.pyGo to http://localhost:8080/ to see the result. The next steps you'll want to do is edit < appname >/server/handlers.py and put in your server-side business logic and edit and create the files in < appname >/html to build up your client-side logic.The templeton moduleThe templeton module has two main functions:- set up middleware to separate static pages from dynamic REST calls.- provide helpers for common tasks, such as handling specific request types.MiddlewareInclude templeton.middleware patches the standard web.py development server to reflect the standard templeton path structure and to better mirror the deployed layout.Paths starting with '/api' are dispatched to a handler.Standard third-party files (JS & CSS, e.g. JQuery) are served from '/templeton'. Running the 'init' command of the templeton script (see above) installs these files for deployment at the same path.All other paths are treated as static files. Static files are now stored in '../html' rather than 'static'. For example, accessing http://localhost:8080/index.html will load ../html/index.html, and http://localhost:8080/scripts/app.js will load ../html/scripts/app.js.HandlersTempleton is geared toward client-rich, REST-based web applications. These typically involve a large amount of JSON. templeton provides decorators to simplify handler code.@get_json is a decorator function that expects the decorated function toreturn a JSON-serializable object, which it uses to construct a properweb.py response.The handlers module also provides helper functions.Load_urls() takes a web.py URL-handler sequence, i.e. (< path >, < class name >, < path >, < class name >, ...), and prepends the REST API path, '/api', to each given path. The default server.py (created by the 'init' script command) uses this function to load urls from handlers.py.get_request_parms() parses the current request's search string and body as JSON and returns the results as (args, body).A trivial example of a JSON handler that echoes back any search-string args:import templeton.handlersclass JsonTest(object): @templeton.handlers.get_json def GET(self): args, body = templeton.handlers.get_request_parms() return args Requirements: · Python
