gocept.registration 0.1.0

Registering a user

Registrations are managed by the registrations utility:

>>> from gocept.registration.registrations import Registrations
>>> registrations = Registrations()

We can now register a user by passing his email address and some additional data:

>>> peter = registrations.register('peter@example.com', {'name': u'Peter'})
>>> peter
<gocept.registration.registrations.Registration object at 0x...>

All registrations have a hash that anonymous identifies them, the email and the data attached:

>>> peter.hash
'<SHA-HASH>'
>>> peter.email
'peter@example.com'
>>> peter.data
{'name': u'Peter'}

Peter’s registration is contained in the utility identified by the hash:

>>> registrations[peter.hash]
<gocept.registration.registrations.Registration object at 0x...>

Peter can now confirm his registration using the hash that was given to him:

>>> registrations.confirm(peter.hash)

Now that he confirmed his registration, it isn’t stored in the utility anymore:

>>> registrations[peter.hash]
Traceback (most recent call last):
KeyError: '<SHA-HASH>'

Application hooks

There are two hooks that applications can tap into for customizing the registration process:

• the ObjectAddedEvent for the registration object, and

• the RegistrationConfirmedEvent when the user confirms his registration

Let’s register a subscriber for both events to demonstrate where each is called:

>>> def registered(event):
...     print event, event.object
>>> import zope.component
>>> from zope.app.container.interfaces import IObjectAddedEvent
>>> zope.component.provideHandler(registered, (IObjectAddedEvent,))

>>> chuck = registrations.register('chuck@example.com', {'name': u'LeChuck'})
<zope.app.container.contained.ObjectAddedEvent object at 0x...>
<gocept.registration.registrations.Registration object at 0x...>

>>> def confirmed(event):
...     print event, event.registration
>>> from gocept.registration.interfaces import IRegistrationConfirmed
>>> zope.component.provideHandler(confirmed, (IRegistrationConfirmed,))

>>> registrations.confirm(chuck.hash)
<gocept.registration.interfaces.RegistrationConfirmedEvent object at 0x...>
<gocept.registration.registrations.Registration object at 0x...>

Let’s clean those registrations up again:

>>> from zope.app.testing import placelesssetup
>>> placelesssetup.tearDown()

Confirmation emails

Sending out registration emails is divided into two parts: creating the email itself, and sending it.
