Addresses

The REST API can be used to manage addresses.

There are no addresses yet.

>>> from mailman.testing.documentation import dump_json
>>> dump_json('http://localhost:9001/3.0/addresses')
http_etag: "..."
start: 0
total_size: 0

When an address is created via the internal API, it is available in the REST API.

>>> from zope.component import getUtility
>>> from mailman.interfaces.usermanager import IUserManager
>>> user_manager = getUtility(IUserManager)
>>> anne = user_manager.create_address('anne@example.com')
>>> from mailman.config import config
>>> transaction = config.db
>>> transaction.commit()

>>> dump_json('http://localhost:9001/3.0/addresses')
entry 0:
    email: anne@example.com
    http_etag: "..."
    original_email: anne@example.com
    registered_on: 2005-08-01T07:49:23
    self_link: http://localhost:9001/3.0/addresses/anne@example.com
http_etag: "..."
start: 0
total_size: 1

Anne’s address can also be accessed directly.

>>> dump_json('http://localhost:9001/3.0/addresses/anne@example.com')
email: anne@example.com
http_etag: "..."
original_email: anne@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/anne@example.com

Bart registers with a mixed-case address. The canonical URL always includes the lower-case version.

>>> bart = user_manager.create_address('Bart.Person@example.com')
>>> transaction.commit()
>>> dump_json(
...     'http://localhost:9001/3.0/addresses/bart.person@example.com')
email: bart.person@example.com
http_etag: "..."
original_email: Bart.Person@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/bart.person@example.com

But his address record can be accessed with the case-preserved version too.

>>> dump_json(
...     'http://localhost:9001/3.0/addresses/Bart.Person@example.com')
email: bart.person@example.com
http_etag: "..."
original_email: Bart.Person@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/bart.person@example.com

When an address has a real name associated with it, this is also available in the REST API.

>>> cris = user_manager.create_address('cris@example.com', 'Cris Person')
>>> transaction.commit()
>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com')
display_name: Cris Person
email: cris@example.com
http_etag: "..."
original_email: cris@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/cris@example.com

Verifying

When the address gets verified, this attribute is available in the REST representation.

>>> from mailman.utilities.datetime import now
>>> anne.verified_on = now()
>>> transaction.commit()
>>> dump_json('http://localhost:9001/3.0/addresses/anne@example.com')
email: anne@example.com
http_etag: "..."
original_email: anne@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/anne@example.com
verified_on: 2005-08-01T07:49:23

Addresses can also be verified through the REST API, by POSTing to the ‘verify’ sub-resource. The POST data is ignored.

>>> dump_json('http://localhost:9001/3.0/addresses/'
...           'cris@example.com/verify', {})
date: ...
server: ...
status: 204

Now Cris’s address is verified.

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com')
display_name: Cris Person
email: cris@example.com
http_etag: "..."
original_email: cris@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/cris@example.com
verified_on: 2005-08-01T07:49:23

If you should ever need to ‘unverify’ an address, POST to the ‘unverify’ sub-resource. Again, the POST data is ignored.

>>> dump_json('http://localhost:9001/3.0/addresses/'
...           'cris@example.com/unverify', {})
date: ...
server: ...
status: 204

Now Cris’s address is unverified.

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com')
display_name: Cris Person
email: cris@example.com
http_etag: "..."
original_email: cris@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/cris@example.com

The user

To link an address to a user, a POST request can be sent to the /user sub-resource of the address. If the user does not exist, it will be created.

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com/user',
...           {'display_name': 'Cris X. Person'})
content-length: 0
content-type: application/json
date: ...
location: http://localhost:9001/3.0/users/1
server: ...
status: 201

The user is now created and the address is linked to it:

>>> cris.user
<User "Cris X. Person" (1) at 0x...>
>>> cris_user = user_manager.get_user('cris@example.com')
>>> cris_user
<User "Cris X. Person" (1) at 0x...>
>>> cris.user == cris_user
True
>>> [a.email for a in cris_user.addresses]
['cris@example.com']

A link to the user resource is now available as a sub-resource.

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com')
display_name: Cris Person
email: cris@example.com
http_etag: "..."
original_email: cris@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/cris@example.com
user: http://localhost:9001/3.0/users/1

To prevent automatic user creation from taking place, add the auto_create parameter to the POST request and set it to False.

>>> dump_json('http://localhost:9001/3.0/addresses/anne@example.com/user',
...           {'display_name': 'Anne User', 'auto_create': False})
Traceback (most recent call last):
...
urllib.error.HTTPError: HTTP Error 403: ...

A request to the /user sub-resource will return the linked user’s representation:

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com/user')
created_on: 2005-08-01T07:49:23
display_name: Cris X. Person
http_etag: "..."
is_server_owner: False
password: ...
self_link: http://localhost:9001/3.0/users/1
user_id: 1

The address and the user can be unlinked by sending a DELETE request on the /user resource. The user itself is not deleted, only the link.

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com/user',
...           method='DELETE')
date: ...
server: ...
status: 204
>>> transaction.abort()
>>> cris.user == None
True
>>> from uuid import UUID
>>> user_manager.get_user_by_id(UUID(int=1))
<User "Cris X. Person" (1) at 0x...>
>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com/user')
Traceback (most recent call last):
...
urllib.error.HTTPError: HTTP Error 404: ...

You can link an existing user to an address by passing the user’s ID in the POST request.

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com/user',
...           {'user_id': 1})
content-length: 0
content-type: application/json
date: ...
server: ...
status: 200

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com/user')
created_on: ...
display_name: Cris X. Person
http_etag: ...
password: ...
self_link: http://localhost:9001/3.0/users/1
user_id: 1

To link an address to a different user, you can either send a DELETE request followed by a POST request, or you can send a PUT request.

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com/user',
...           {'display_name': 'Cris Q Person'}, method="PUT")
content-length: 0
content-type: application/json
date: ...
location: http://localhost:9001/3.0/users/2
server: ...
status: 201

>>> dump_json('http://localhost:9001/3.0/addresses/cris@example.com/user')
created_on: ...
display_name: Cris Q Person
http_etag: ...
password: ...
self_link: http://localhost:9001/3.0/users/2
user_id: 2

User addresses

Users control addresses. The canonical URLs for these user-controlled addresses live in the /addresses namespace.

>>> dave = user_manager.create_user('dave@example.com', 'Dave Person')
>>> transaction.commit()
>>> dump_json('http://localhost:9001/3.0/users/dave@example.com/addresses')
entry 0:
    display_name: Dave Person
    email: dave@example.com
    http_etag: "..."
    original_email: dave@example.com
    registered_on: 2005-08-01T07:49:23
    self_link: http://localhost:9001/3.0/addresses/dave@example.com
    user: http://localhost:9001/3.0/users/3
http_etag: "..."
start: 0
total_size: 1

>>> dump_json('http://localhost:9001/3.0/addresses/dave@example.com')
display_name: Dave Person
email: dave@example.com
http_etag: "..."
original_email: dave@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/dave@example.com
user: http://localhost:9001/3.0/users/3

A user can be associated with multiple email addresses. You can add new addresses to an existing user.

>>> dump_json(
...     'http://localhost:9001/3.0/users/dave@example.com/addresses', {
...           'email': 'dave.person@example.org'
...           })
content-length: 0
content-type: application/json
date: ...
location: http://localhost:9001/3.0/addresses/dave.person@example.org
server: ...
status: 201

When you add the new address, you can give it an optional display name.

>>> dump_json(
...     'http://localhost:9001/3.0/users/dave@example.com/addresses', {
...           'email': 'dp@example.org',
...           'display_name': 'Davie P',
...           })
content-length: 0
content-type: application/json
date: ...
location: http://localhost:9001/3.0/addresses/dp@example.org
server: ...
status: 201

The user controls these new addresses.

>>> dump_json('http://localhost:9001/3.0/users/dave@example.com/addresses')
entry 0:
    email: dave.person@example.org
    http_etag: "..."
    original_email: dave.person@example.org
    registered_on: 2005-08-01T07:49:23
    self_link: http://localhost:9001/3.0/addresses/dave.person@example.org
    user: http://localhost:9001/3.0/users/3

total_size: 3

Preferred address

Each user can have a preferred address. Initially, every user’s preferred address is unset.

>>> ram = user_manager.create_user('ram@example.com', 'Ram Person')
>>> transaction.commit()
>>> dump_json(
...    'http://localhost:9001/3.1/users/ram@example.com/addresses')
entry 0:
    display_name: Ram Person
    email: ram@example.com
    http_etag: "..."
    original_email: ram@example.com
    registered_on: 2005-08-01T07:49:23
    self_link: http://localhost:9001/3.1/addresses/ram@example.com
    user: http://localhost:9001/3.1/users/00000000000000000000000000000004
http_etag: "..."
start: 0
total_size: 1
>>> import pdb
>>> dump_json('http://localhost:9001/3.1/users/ram@example.com/preferred_address')
Traceback (most recent call last):
...
urllib.error.HTTPError: HTTP Error 404: ...

Setting Ram’s preferred addresses requires that it first be verified:

>>> dump_json('http://localhost:9001/3.1/users/ram@example.com/preferred_address',
...     {'email': 'ram@example.com'})
Traceback (most recent call last):
...
urllib.error.HTTPError: HTTP Error 400: Ram Person <ram@example.com>

Verify Ram’s address first:

>>> addr = ram.addresses[0]
>>> addr.verified_on = now()
>>> transaction.commit()

Now, Ram can set his preferred address:

>>> dump_json('http://localhost:9001/3.1/users/ram@example.com/preferred_address',
...     {'email': 'ram@example.com'})
content-length: 0
content-type: application/json
date: ...
location: http://localhost:9001/3.1/addresses/ram@example.com
server: ...
status: 201
>>> dump_json('http://localhost:9001/3.1/users/ram@example.com/preferred_address')
display_name: Ram Person
email: ram@example.com
http_etag: "..."
original_email: ram@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.1/addresses/ram@example.com
user: http://localhost:9001/3.1/users/00000000000000000000000000000004
verified_on: 2005-08-01T07:49:23

To unset Ram’s preferred address, call a DELETE on preferred address resource:

>>> dump_json('http://localhost:9001/3.1/users/ram@example.com/preferred_address',
...     method='DELETE')
date: ...
server: ...
status: 204

Memberships

Addresses can be subscribed to mailing lists. When they are, all the membership records for that address are easily accessible via the REST API.

Elle registers several email addresses.

>>> elle = user_manager.create_user('elle@example.com', 'Elle Person')
>>> subscriber = list(elle.addresses)[0]
>>> elle.register('eperson@example.com')
<Address: eperson@example.com [not verified] at ...>
>>> elle.register('elle.person@example.com')
<Address: elle.person@example.com [not verified] at ...>

Elle subscribes to two mailing lists with one of her addresses.

>>> from mailman.app.lifecycle import create_list
>>> ant = create_list('ant@example.com')
>>> bee = create_list('bee@example.com')
>>> ant.subscribe(subscriber)
<Member: Elle Person <elle@example.com> on ant@example.com
         as MemberRole.member>
>>> bee.subscribe(subscriber)
<Member: Elle Person <elle@example.com> on bee@example.com
         as MemberRole.member>
>>> transaction.commit()

Elle can get her memberships for each of her email addresses.

>>> dump_json('http://localhost:9001/3.0/addresses/'
...           'elle@example.com/memberships')
entry 0:
    address: http://localhost:9001/3.0/addresses/elle@example.com
    delivery_mode: regular
    display_name: Elle Person
    email: elle@example.com
    http_etag: "..."

    member_id: 1
    role: member
    self_link: http://localhost:9001/3.0/members/1
    subscription_mode: as_address
    user: http://localhost:9001/3.0/users/5
entry 1:
    address: http://localhost:9001/3.0/addresses/elle@example.com
    delivery_mode: regular
    display_name: Elle Person
    email: elle@example.com
    http_etag: "..."
    list_id: bee.example.com
    member_id: 2
    role: member
    self_link: http://localhost:9001/3.0/members/2

...           'eperson@example.com/memberships')
http_etag: "..."

total_size: 0

When Elle subscribes to the bee list again with a different address, this does not show up in the list of memberships for his other address.

>>> subscriber = user_manager.get_address('eperson@example.com')
>>> bee.subscribe(subscriber)
<Member: eperson@example.com on bee@example.com as MemberRole.member>
>>> transaction.commit()

>>> dump_json('http://localhost:9001/3.0/addresses/'
...           'elle@example.com/memberships')
entry 0:
    address: http://localhost:9001/3.0/addresses/elle@example.com
    delivery_mode: regular
    display_name: Elle Person
    email: elle@example.com
    http_etag: "..."

Deleting

Addresses can be deleted via the REST API.

>>> fred = user_manager.create_address('fred@example.com', 'Fred Person')
>>> transaction.commit()
>>> dump_json('http://localhost:9001/3.0/addresses/fred@example.com')
display_name: Fred Person
email: fred@example.com
http_etag: "..."
original_email: fred@example.com
registered_on: 2005-08-01T07:49:23
self_link: http://localhost:9001/3.0/addresses/fred@example.com

>>> dump_json('http://localhost:9001/3.0/addresses/fred@example.com',
...     method='DELETE')
date: ...
server: ...
status: 204
>>> transaction.abort()

>>> print(user_manager.get_address('fred@example.com'))
None

If an address is linked to a user, deleting the address does not delete the user, it just unlinks it.

>>> gwen = user_manager.create_user('gwen@example.com', 'Gwen Person')
>>> transaction.commit()
>>> dump_json('http://localhost:9001/3.0/users/6/addresses')
entry 0:
    display_name: Gwen Person
