.. _rest_comments:

Get Comments
------------

This allows you to get data about comments, given a bug ID or comment ID.

**Request**

To get all comments for a particular bug using the bug ID or alias:

.. code-block:: text

   GET /rest/bug/(id_or_alias)/comment

To get a specific comment based on the comment ID:

.. code-block:: text

   GET /rest/bug/comment/(comment_id)

===============  ========  ======================================================
name             type      description
===============  ========  ======================================================
**id_or_alias**  mixed     A single integer bug ID or alias.
**comment_id**   int       A single integer comment ID.
new_since        datetime  If specified, the method will only return comments
                           *newer* than this time. This only affects comments
                           returned from the ``ids`` argument. You will always be
                           returned all comments you request in the
                           ``comment_ids`` argument, even if they are older than
                           this date.
===============  ========  ======================================================

**Response**

.. code-block:: js

   {
     "bugs": {
       "35": {
         "comments": [
           {
             "time": "2000-07-25T13:50:04Z",
             "text": "test bug to fix problem in removing from cc list.",
             "bug_id": 35,
             "count": 0,
             "attachment_id": null,
             "is_private": false,
             "is_markdown" : true,
             "tags": [],
             "creator": "user@bugzilla.org",
             "creation_time": "2000-07-25T13:50:04Z",
             "id": 75
           }
         ]
       }
     },
     "comments": {}
   }

Two items are returned:

``bugs`` This is used for bugs specified in ``ids``. This is an object,
where the keys are the numeric IDs of the bugs, and the value is
a object with a single key, ``comments``, which is an array of comments.
(The format of comments is described below.)

Any individual bug will only be returned once, so if you specify an ID
multiple times in ``ids``, it will still only be returned once.

``comments`` Each individual comment requested in ``comment_ids`` is
returned here, in a object where the numeric comment ID is the key,
and the value is the comment. (The format of comments is described below.)

A "comment" as described above is a object that contains the following items:

=============  ========  ========================================================
name           type      description
=============  ========  ========================================================
id             int       The globally unique ID for the comment.
bug_id         int       The ID of the bug that this comment is on.
attachment_id  int       If the comment was made on an attachment, this will be
                         the ID of that attachment. Otherwise it will be null.
count          int       The number of the comment local to the bug. The
                         Description is 0, comments start with 1.
text           string    The actual text of the comment.
creator        string    The login name of the comment's author.
time           datetime  The time (in Bugzilla's timezone) that the comment was
                         added.
creation_time  datetime  This is exactly same as the ``time`` key. Use this
                         field instead of ``time`` for consistency with other
                         methods including :ref:`rest_single_bug` and
                         :ref:`rest_attachments`.

                         For compatibility, ``time`` is still usable. However,
                         please note that ``time`` may be deprecated and removed
                         in a future release.

is_private     boolean   ``true`` if this comment is private (only visible to a
                         certain group called the "insidergroup"), ``false``
                         otherwise.
is_markdown    boolean   ``true`` if this comment needs Markdown processing;
                         ``false`` otherwise.
tags           array     An array of comment tags currently set for the comment.
=============  ========  ========================================================

**Errors**

This method can throw all the same errors as :ref:`rest_single_bug`. In addition,
it can also throw the following errors:

* 110 (Comment Is Private)
  You specified the id of a private comment in the "comment_ids"
  argument, and you are not in the "insider group" that can see
  private comments.
* 111 (Invalid Comment ID)
  You specified an id in the "comment_ids" argument that is invalid--either
  you specified something that wasn't a number, or there is no comment with
  that id.

                       If you are not in the time tracking group, this value will
