Upgrading from Django's previous comment system
|
|
===============================================
|
|
|
|
Prior versions of Django included an outdated, undocumented comment system. Users who reverse-engineered this framework will need to upgrade to use the
|
|
new comment system; this guide explains how.
|
|
|
|
The main changes from the old system are:
|
|
|
|
* This new system is documented.
|
|
|
|
* It uses modern Django features like :doc:`forms </topics/forms/index>` and
|
|
:doc:`modelforms </topics/forms/modelforms>`.
|
|
|
|
* It has a single ``Comment`` model instead of separate ``FreeComment`` and
|
|
``Comment`` models.
|
|
|
|
* Comments have "email" and "URL" fields.
|
|
|
|
* No ratings, photos and karma. This should only effect World Online.
|
|
|
|
* The ``{% comment_form %}`` tag no longer exists. Instead, there's now two
|
|
functions: ``{% get_comment_form %}``, which returns a form for posting a
|
|
new comment, and ``{% render_comment_form %}``, which renders said form
|
|
using the ``comments/form.html`` template.
|
|
|
|
* The way comments are include in your URLconf have changed; you'll need to
|
|
replace::
|
|
|
|
(r'^comments/', include('django.contrib.comments.urls.comments')),
|
|
|
|
with::
|
|
|
|
(r'^comments/', include('django.contrib.comments.urls')),
|
|
|
|
Upgrading data
|
|
--------------
|
|
|
|
The data models for Django's comment system have changed, as have the
|
|
table names. Before you transfer your existing data into the new comments
|
|
system, make sure that you have installed the new comments system as
|
|
explained in the
|
|
:doc:`quick start guide </ref/contrib/comments/index>`.
|
|
This will ensure that the new tables have been properly created.
|
|
|
|
To transfer your data into the new comments system, you'll need to directly
|
|
run the following SQL:
|
|
|
|
.. code-block:: sql
|
|
|
|
BEGIN;
|
|
|
|
INSERT INTO django_comments
|
|
(content_type_id, object_pk, site_id, user_name, user_email, user_url,
|
|
comment, submit_date, ip_address, is_public, is_removed)
|
|
SELECT
|
|
content_type_id, object_id, site_id, person_name, '', '', comment,
|
|
submit_date, ip_address, is_public, not approved
|
|
FROM comments_freecomment;
|
|
|
|
INSERT INTO django_comments
|
|
(content_type_id, object_pk, site_id, user_id, user_name, user_email,
|
|
user_url, comment, submit_date, ip_address, is_public, is_removed)
|
|
SELECT
|
|
content_type_id, object_id, site_id, user_id, '', '', '', comment,
|
|
submit_date, ip_address, is_public, is_removed
|
|
FROM comments_comment;
|
|
|
|
UPDATE django_comments SET user_name = (
|
|
SELECT username FROM auth_user
|
|
WHERE django_comments.user_id = auth_user.id
|
|
) WHERE django_comments.user_id is not NULL;
|
|
UPDATE django_comments SET user_email = (
|
|
SELECT email FROM auth_user
|
|
WHERE django_comments.user_id = auth_user.id
|
|
) WHERE django_comments.user_id is not NULL;
|
|
|
|
COMMIT;
