1.2.3.3 Using Alternative Drivers

If you don't want to use SQLite for the auth storage you could use a different database or you could use the file driver instead. Here is the same code setup for a file driver. You will be need to delete the all the files in the example-web-auth directory if you have already run the script before.

Here are the same examples modifed to use only the auth file driver with no database required.

import sys; sys.path.append('../../../') # show python where the web modules are
import web.database, web.auth

# Create authManager object and setup the environment
authManager = web.auth.setup(
    storage='file',
    dir='example-web-auth'
)
authManager.addApplication('app')
authManager.addUser('test', '123')
authManager.addUser(
    'john',
    'bananas',
    'John',
    'Smith',
    'johnsmith@example.com'
)
authManager.setAccessLevel('john', 'app', 1)
print "All done!"

#!/usr/bin/env python

"""Auth Example. Username=john and Password=bananas (Case sensitive)"""

# show python where the web modules are
import sys, os
sys.path.append('../')
sys.path.append('../../../') 

import web, web.database, web.auth, web.session
import web.error; web.error.handle() # Automatically display errors

session = web.session.start(
    storage='file',
    dir='../doc/src/lib/example-web-auth-session',
    app='app'
)
user = web.auth.start(
    session, storage='file',
    dir='../doc/src/lib/example-web-auth', 
    idle=100, expire=200
)

# No HTTP content-type headers should be printed before the user.valid() method
# if the autoLogin feature is enabled as this will print its own header. 

if user.valid():   # See if the User is signed in else present sign in form.
    print web.header() 
    if web.cgi.has_key('signOut'):
        user.signOut()
