=head1 NAME

MT::Author - Movable Type author record

=head1 SYNOPSIS

use MT::Author;
    my $author = MT::Author->new;
    $author->name('Foo Bar');
    $author->set_password('secret');
    $author->save
        or die $author->errstr;

my $author = MT::Author->load($author_id);

=head1 DESCRIPTION

An I<MT::Author> object represents a user in the Movable Type system. It
contains profile information (name, nickname, email address, etc.), global
permissions settings (blog creation, activity log viewing), and authentication
information (password, public key). It does not contain any per-blog
permissions settings--for those, look at the I<MT::Permission> object.

=head1 USAGE

As a subclass of I<MT::Object>, I<MT::Author> inherits all of the
data-management and -storage methods from that class; thus you should look
at the I<MT::Object> documentation for details about creating a new object,
loading an existing object, saving an object, etc.

The following methods are unique to the I<MT::Author> interface:

=head2 $author->set_password($pass)

One-way encrypts I<$pass> with a randomly-generated salt, using the Unix
I<crypt> function, and sets the I<password> data field in the I<MT::Author>
object I<$author>.

Because the password is one-way encrypted, there is B<no way> of recovering
the initial password.

=head2 $author->is_valid_password($check_pass)

Tests whether I<$check_pass> is a valid password for the I<MT::Author> object
I<$author> (ie, whether it matches the password originally set using
I<set_password>). This check is done by one-way encrypting I<$check_pass>,
using the same salt used to encrypt the original password, then comparing the
two encrypted strings for equality.

=head1 DATA ACCESS METHODS

The I<MT::Author> object holds the following pieces of data. These fields can
be accessed and set using the standard data access methods described in the
I<MT::Object> documentation.

=over 4

=item * id

The numeric ID of the author.

=item * name

The username of the author. This is the username used to log in to the system.

=item * nickname

The author nickname (or "display" name). This is the preferred name used for publishing the author's name.

=item * password

The author's password, one-way encrypted. If you wish to check the validity of
a password, you should use the I<is_valid_password> method, above.

=item * type

The type of author record. Currently, MT stores authenticated commenters in the author table. The type column can be one of AUTHOR or COMMENTER (constants defined in this package).

=item * status

A column that defines whether the records of an AUTHOR type are ACTIVE, INACTIVE or PENDING (constants declared in this package).

=item * commenter_status

This method requires a blog id to be passed as the argument and a value of APPROVED, BANNED or PENDING (constants declared in this package) is returned.

=item * email

The author's email address.

=item * url

The author's homepage URL.

=item * hint

The answer to the question used when recovering the user's password.

=item * external_id

A column for holding a value used to synchronize the MT author record with an external record.

=item * can_create_blog

A boolean flag specifying whether the author has permission to create a new
blog in the system.

=item * can_view_log

A boolean flag specifying whether the author has permission to view the global
system activity log.

=item * created_by

The author ID of the author who created this author. If the author was created by a process where no user was logged in to Movable Type, the created_by column will be empty.

=item * public_key

The author's ASCII-armoured public key, to be used in the future for verifying
incoming email messages.

=back

=head1 DATA LOOKUP

In addition to numeric ID lookup, you can look up or sort records by any
combination of the following fields. See the I<load> documentation in
I<MT::Object> for more information.

=over 4

=item * name

=item * email

=back

=head1 NOTES

=over 4

=item *

When you remove an author using I<MT::Author::remove>, in addition to removing
the author record, all of the author's permissions (I<MT::Permission> objects)
will be removed, as well.

=back

=head1 AUTHOR & COPYRIGHTS

Please see the I<MT> manpage for author, copyright, and license information.
