    <p>I'm trying to make bottle.py work with repoze.who, and so far have managed to put together the following very simplistic program to get it working, using a combination of various examples I've found. Obviously this isn't something I'd run in production, I'm just trying to make the least complicated code I can so that I can learn how to use this - but unfortunately, tutorials for using bottle.py with repoze.who are very few and far between.</p> <p>This example below works, and allows someone to login with username/password of admin/admin. What am I supposed to do with repoze.who to make the logout() function work? I gather there's a forget function that might be for this purpose, but I can't work out how I'm meant to call it.</p> <p>Thanks.</p> <pre><code>from bottle import route, run, app, get, abort, request from StringIO import StringIO import repoze from repoze.who.middleware import PluggableAuthenticationMiddleware from repoze.who.interfaces import IIdentifier from repoze.who.interfaces import IChallenger from repoze.who.plugins.basicauth import BasicAuthPlugin from repoze.who.plugins.auth_tkt import AuthTktCookiePlugin from repoze.who.plugins.cookie import InsecureCookiePlugin from repoze.who.plugins.form import FormPlugin from repoze.who.plugins.htpasswd import HTPasswdPlugin from repoze.who.classifiers import default_request_classifier from repoze.who.classifiers import default_challenge_decider import logging, sys import pprint @route('/') def root(): if request.environ.get('repoze.who.identity') is None: abort(401, "Not authenticated") return "Authenticated" @route('/hello') def index(): identity = request.environ.get('repoze.who.identity') if identity == None: abort(401, "Not authenticated") user = identity.get('repoze.who.userid') return '&lt;b&gt;Hello %s!&lt;/b&gt;' % user @route('/logout') def logout(): # I have no idea what to put here pass io = StringIO() salt = 'aa' for name, password in [ ('admin', 'admin'), ('paul', 'paul') ]: io.write('%s:%s\n' % (name, password)) io.seek(0) def cleartext_check(password, hashed): return password == hashed htpasswd = HTPasswdPlugin(io, cleartext_check) basicauth = BasicAuthPlugin('repoze.who') auth_tkt = AuthTktCookiePlugin('secret', 'auth_tkt') form = FormPlugin('__do_login', rememberer_name='auth_tkt') form.classifications = { IIdentifier:['browser'], IChallenger:['browser'] } identifiers = [('form', form),('auth_tkt',auth_tkt),('basicauth',basicauth)] authenticators = [('htpasswd', htpasswd)] challengers = [('form',form), ('basicauth',basicauth)] mdproviders = [] log_stream = None import os if os.environ.get('WHO_LOG'): log_stream = sys.stdout middleware = PluggableAuthenticationMiddleware( app(), identifiers, authenticators, challengers, mdproviders, default_request_classifier, default_challenge_decider, log_stream = log_stream, log_level = logging.DEBUG ) if __name__ == '__main__': run(app=middleware, host='0.0.0.0', port=8080, reloader=True) else: application = middleware run(host='0.0.0.0', port=8080) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
