=head1 NAME

MojoX::Authentication::Model::Db


=head1 SYNOPSIS

   use MojoX::Authentication::Model::Db;


=head1 DESCRIPTION

This class is not supposed to be used directly but through
L<MojoX::Authentication::Model> instead.

This class composes role L<MojoX::Authentication::Model::Role::Local>
and inherits its methods.

=head1 INTERFACE

=head2 B<< column_remaps >>

   my $aref = $self->column_remaps;

=head2 B<< create >>

   my $instance = MojoX::Authentication::Model::Db->new($config, %args);

Constructor. 

Can receive the configuration either from a more "generic" C<$config>
hash as well as direct named arguments.

First a name is determined, either from C<$args{name}> or C<hashy> by
default. Then C<$config> is looked at for a corresponding value, which
is either expected to be missing/C<undef> or be a hash reference. In
case a hash reference is found, its pairs override those on C<%args>,
with the only exception of the key C<name> which is preserved if already
present or set to the default otherwise.

If the C<wmdb> key is present, a new instance of the class is created and
returned. Otherwise, the method returns C<undef>.

Also accepts parameters for the following accessors: L</name> (only from
C<%args>, see above), L</table>, L</column_remaps>, L</crypt_passphrase>
(inherited from role L<MojoX::Authentication::Model::Role::Local>),
L</remaps>, and L</username_column>.


=head2 B<< load_user >>

   my $user = $provider->load_user($ignored, $uid);

Load the user by its userid, compatibly with
L<mojolicious::plugin::authentication>'s interface for loading users.
the first parameter (which is supposed to be a controller instance) is
ignored.

See L</id_column>.

=head2 B<< load_user_by_name >>

   my $user = $provider->load_user_by_name($ignored, $username);

Load the user by its username, according to L</name_column>.

=head2 B<< name >>

   my $name = $provider->name;

Name assigned to the provider (e.g. if you want to use different
databases at the same time and hence want to instantiate this class
multiple times).

=head2 B<< remaps >>

   my $aref = $provider->remaps;

Accessor for the list of remaps, handled by
L<MojoX::Authentication::Model::Role::Remap>.

Make sure that the mapping contains a way to map the column containing
the secret to check in correspondence of key C<secret>, otherwise
L<MojoX::Authentication::Model::Role::Local> will fail to check secrets.

=head2 B<< save_user >>

   $provider->save_user($user);    # OR
   $provider->save_user($user, $is_secret_cleartext);

Save a user.

The input C<$user> is supposed to be a hash reference with I<at least>
keys C<name> (for the username/userid) and C<secret> (for the secret).
it <MAY> contain other key/value pairs, which will be copied.

The C<secret> is supposed to be already hashed. It is possible to set
the optional additional parameter C<$is_secret_cleartext> to a true
value to indicate that the hashing should be done by the function before
saving the user.

=head2 B<< table >>

   my $string = $provider->table;

Returns the name of the table where user accounts are kept. Defaults to
C<accounts>.

The names of the columns with I<interesting> values are accessible
through L</id_column>, L</name_column> and L</secret_column>.

=head2 B<< username_column >>

   my $string = $provider->name_column;

Returns the name of the column where the username is kept. Defaults to
C<name>.

See also L</table>.

=head2 B<< wmdb >>

   my $wmdb = $provider->wmdb;

Accessor to the L<MojoX::MojoDbWrap> object wrapping the relevant
database access object (most probably an object of either
L<Mojo::SQLite> or L<Mojo::Pg> class).
