User container for the Kofa
***************************

.. :doctest:
.. :layer: waeup.kofa.testing.KofaUnitTestLayer

Before we can start, we need some password managers available:

    >>> from zope.app.authentication.placelesssetup import (
    ...   PlacelessSetup)
    >>> PlacelessSetup().setUp()

We can create a user container which will hold the useraccounts for
us:

    >>> from waeup.kofa.userscontainer import UsersContainer
    >>> myusers = UsersContainer()

We can add users, just by passing a name, a password, and (optionally)
a title and a description:

    >>> myusers.addUser('bob', 'bobssecret')

Now, Bob is in the container:

    >>> list(myusers)
    [u'bob']

We can get Bob's account:

    >>> bob = myusers['bob']
    >>> bob
    <waeup.kofa.authentication.Account object at 0x...>

    >>> bob.name
    'bob'

    >>> bob.title
    'bob'

    >>> bob.description


As we did not give a title, the name was taken instead
for title (but not for description). The password, however, is stored encoded:

    >>> bob.password
    '{SSHA}...'

We can export user accounts:

    >>> from waeup.kofa.userscontainer import UsersExporter
    >>> import os
    >>> import tempfile
    >>> workdir = tempfile.mkdtemp()
    >>> outfile = os.path.join(workdir, 'myoutput.csv')
    >>> exporter = UsersExporter()
    >>> site = {'users':myusers}
    >>> exporter.export_all(site, outfile)
    >>> result = open(outfile, 'rb').read()
    >>> 'name,title,public_name,description,email,phone,roles,local_roles,password' in result
    True
    >>> '{SSHA}' in result
    True

We can delete users:

    >>> myusers.delUser('alice')

The container won't complain, although there is no ``alice`` stored
yet. But we can really delete users:

    >>> myusers.delUser('bob')
    >>> list(myusers)
    []

Clean up:

    >>> import shutil
    >>> shutil.rmtree(workdir)
