=head1 NAME

Gruntmaster::Data - Gruntmaster 6000 Online Judge -- database interface and tools

=head1 SYNOPSIS

  my $db = Gruntmaster::Data->connect('dbi:Pg:');

  my $problem = $db->problem('my_problem');
  $problem->update({timeout => 2.5}); # Set time limit to 2.5 seconds
  $problem->rerun; # And rerun all jobs for this problem

  # ...

  my $contest = $db->contests->create({ # Create a new contest
    id => 'my_contest',
    name => 'My Awesome Contest',
    start => time + 100,
    end => time + 1900,
  });
  $db->contest_problems->create({ # Add a problem to the contest
    contest => 'my_contest',
    problem => 'my_problem',
  });

  say 'The contest has not started yet' if $contest->is_pending;

  # ...

  my @jobs = $db->jobs->search({contest => 'my_contest', owner => 'MGV'})->all;
  $_->rerun for @jobs; # Rerun all jobs sent by MGV in my_contest

=head1 DESCRIPTION

Gruntmaster::Data is the interface to the Gruntmaster 6000 database. Read the L<DBIx::Class> documentation for usage information.

In addition to the typical DBIx::Class::Schema methods, this module contains several convenience methods:

=over

=item contests

Equivalent to C<< $schema->resultset('Contest') >>

=item contest_problems

Equivalent to C<< $schema->resultset('ContestProblem') >>

=item jobs

Equivalent to C<< $schema->resultset('Job') >>

=item problems

Equivalent to C<< $schema->resultset('Problem') >>

=item users

Equivalent to C<< $schema->resultset('User') >>

=item contest($id)

Equivalent to C<< $schema->resultset('Contest')->find($id) >>

=item job($id)

Equivalent to C<< $schema->resultset('Job')->find($id) >>

=item problem($id)

Equivalent to C<< $schema->resultset('Problem')->find($id) >>

=item user($id)

Equivalent to C<< $schema->resultset('User')->find($id) >>

=item user_list

Returns a list of users as an arrayref containing hashrefs.

=item user_entry($id)

Returns a hashref with information about the user $id.

=item problem_list([%args])

Returns a list of problems grouped by level. A hashref with levels as keys.

Takes the following arguments:

=over

=item owner

Only show problems owned by this user

=item contest

Only show problems in this contest

=back

=item problem_entry($id, [$contest, $user])

Returns a hashref with information about the problem $id. If $contest and $user are present, problem open data is updated.

=item contest_list([%args])

Returns a list of contests grouped by state. A hashref with the following keys:

=over

=item pending

An arrayref of hashrefs representing pending contests

=item running

An arrayref of hashrefs representing running contests

=item finished

An arrayref of hashrefs representing finished contests

=back

Takes the following arguments:

=over

=item owner

Only show contests owned by this user.

=back

=item contest_entry($id)

Returns a hashref with information about the contest $id.

=item job_list([%args])

Returns a list of jobs as an arrayref containing hashrefs. Takes the following arguments:

=over

=item owner

Only show jobs submitted by this user.

=item contest

Only show jobs submitted in this contest.

=item problem

Only show jobs submitted for this problem.

=item page

Show this page of results. Defaults to 1. Pages have 10 entries, and the first page has the most recent jobs.

=back

=item job_entry($id)

Returns a hashref with information about the job $id.

=back
