=head1 NAME

RT::SavedSearch - an API for saving and retrieving search form values.

=head1 SYNOPSIS

  use RT::SavedSearch

=head1 DESCRIPTION

SavedSearch is an object based on L<RT::SharedSetting> that can belong
to either an L<RT::User> or an L<RT::Group>. It consists of an ID,
a description, and a number of search parameters.

=cut

package RT::SavedSearch;

use strict;
use warnings;

use base qw/RT::SharedSetting/;

=head1 METHODS

=head2 ObjectName

An object of this class is called "search"

=cut

sub ObjectName { "search" } # loc

sub PostLoad {
    my $self = shift;
    $self->{'Type'} = $self->{'Attribute'}->SubValue('SearchType');
}

sub SaveAttribute {
    my $self   = shift;
    my $object = shift;
    my $args   = shift;

    my $params = $args->{'SearchParams'};

    $params->{'SearchType'} = $args->{'Type'} || 'Ticket';

    return $object->AddAttribute(
        'Name'        => 'SavedSearch',
        'Description' => $args->{'Name'},
        'Content'     => $params,
    );
}


sub UpdateAttribute {
    my $self = shift;
    my $args = shift;
    my $params = $args->{'SearchParams'} || {};

    my ($status, $msg) = $self->{'Attribute'}->SetSubValues(%$params);

    if ($status && $args->{'Name'}) {
        ($status, $msg) = $self->{'Attribute'}->SetDescription($args->{'Name'});
    }

    return ($status, $msg);
}

=head2 RT::SavedSearch->EscapeDescription STRING

This is a class method because system-level saved searches aren't true
C<RT::SavedSearch> objects but direct C<RT::Attribute> objects.

Returns C<STRING> with all square brackets except those in C<[_1]> escaped,
ready for passing as the first argument to C<loc()>.

=cut

sub EscapeDescription {
    my $self = shift;
    my $desc = shift;
    if ($desc) {
        # We only use [_1] in saved search descriptions, so let's escape other "["
        # and "]" unless they are escaped already.
        $desc =~ s/(?<!~)\[(?!_1\])/~[/g;
        $desc =~ s/(?<!~)(?<!\[_1)\]/~]/g;
    }
    return $desc;
}

=head2 Type

Returns the type of this search, e.g. 'Ticket'.  Useful for denoting the
saved searches that are relevant to a particular search page.

=cut

sub Type {
    my $self = shift;
    return $self->{'Type'};
}

### Internal methods

# _PrivacyObjects: returns a list of objects that can be used to load, create,
# etc. saved searches from. You probably want to use the wrapper methods like
# ObjectsForLoading, ObjectsForCreating, etc.

sub _PrivacyObjects {
    my $self        = shift;
    my ($has_attr) = @_;
    my $CurrentUser = $self->CurrentUser;

    my $groups = RT::Groups->new($CurrentUser);
    $groups->LimitToUserDefinedGroups;
    $groups->WithCurrentUser;
    if ($has_attr) {
        my $attrs = $groups->Join(
            ALIAS1 => 'main',
            FIELD1 => 'id',
            TABLE2 => 'Attributes',
            FIELD2 => 'ObjectId',
        );
        $groups->Limit(
            ALIAS => $attrs,
            FIELD => 'ObjectType',
            VALUE => 'RT::Group',
        );
        $groups->Limit(
            ALIAS => $attrs,
            FIELD => 'Name',
            VALUE => $has_attr,
        );
    }

    return ( $CurrentUser->UserObj, @{ $groups->ItemsArrayRef() } );
}

sub ObjectsForLoading {
    my $self = shift;
    return grep { $self->CurrentUserCanSee($_) } $self->_PrivacyObjects( "SavedSearch" );
}

=head2 ObjectsForCreating

In the context of the current user, load a list of objects that could have searches
saved under, including the current user and groups. This method considers both rights
and group membership when creating the list of objects for saved searches.

=cut

sub ObjectsForCreating {
    my $self = shift;
    my @objects = $self->_PrivacyObjects( );
    my @create_objects;

    foreach my $object ( @objects ) {
        # Users need ModifySelf to save personal searches
        if ( ref $object
             && ref $object eq 'RT::User'
             && $self->CurrentUser->HasRight( Right => 'ModifySelf', Object => $object ) ) {
            push @create_objects, $object;
        }

        # On groups, the EditSavedSearches right manages create and edit
        if ( ref $object
             && ref $object eq 'RT::Group'
             && $self->CurrentUser->HasRight( Right => 'EditSavedSearches', Object => $object ) ) {
            push @create_objects, $object;
        }
    }

    return @create_objects;
}

RT::Base->_ImportOverlays();
