web2py 1.56 is out, including a new web site with better documentation http://www.web2py.com What is web2py? ============= - It is the web framework used by PyCon 2009 for registration. - It a very easy and very powerful Python web framework. - It is fast and rock solid. It has a very clean design and it is strong on security. - Includes a web based development environment, maintenance environment, and database administrative interface. - Includes a Database Abstraction Layer that works with SQLite, MySQL, PostgreSQL, FireBird, MSSQL, Oracle, AND the Google App Engine. The DAL does migrations. - Includes a pure Python based template language with no indentation requirements. - Includes jQuery, simplejson, markdown, feedparser, PyRSS2, nicEdit, EditArea and a lot more. - Runs on any platform that runs python. The binary versions can even run off a USB drive without dependences. - The same apps can run on a PC with Oracle or on the Google App Engine or on Windows Mobile, without changes, including DB API. New features Include: ================= - Authentication - Authorization (Role Based Access Controller) - CRUD - portable url fetch function - portable geocoding function - PEP8 compliant - Python 2.5 and Python 2.6 compliant - Runs on Jython (although without db drivers) - Runs on IronPython (although without CSV, db drivers and internal web-server) - DAL shortcuts - SQLFORM has default image preview - new generic.html view - more examples and documentation - always backward compatible Example of code (complete app) ========================= ## in model db.py from gluon.tools import * db=SQLDB() db.define_table('puppy', db.Field('name'), db.Field('image','upload')) auth=Auth(globals(),db) crud=Crud(flobals(),db) ## in controller default.py def user(): " to expose register, login, logout, etc " return dict(form=auth()) @auth.requires_login() def data(): " to expose select, create, update, delete, etc " return dict(form=crud()) @auth.requires_login() def download(): " for downloading uploaded images " return response.download(request,db) ## in view default/user.html {{extend 'layout.html'}} <div>{{=form}}</div> ## in view default/data.html {{extend 'layout.html'}} <div>{{=form}}</div> This complete code will allow to register, login, change password, upload images of puppies (with relative names), select puppies, edit records, read and preview images, enforce authorization, and more.
