332 Gruntmaster::Data is the interface to the Gruntmaster 6000 database. Read the L<DBIx::Class> documentation for usage information.
334 In addition to the typical DBIx::Class::Schema methods, this module contains several convenience methods:
340 Equivalent to C<< $schema->resultset('Contest') >>
342 =item contest_problems
344 Equivalent to C<< $schema->resultset('ContestProblem') >>
348 Equivalent to C<< $schema->resultset('Job') >>
352 Equivalent to C<< $schema->resultset('Problem') >>
356 Equivalent to C<< $schema->resultset('User') >>
360 Equivalent to C<< $schema->resultset('Contest')->find($id) >>
364 Equivalent to C<< $schema->resultset('Job')->find($id) >>
368 Equivalent to C<< $schema->resultset('Problem')->find($id) >>
372 Equivalent to C<< $schema->resultset('User')->find($id) >>
376 Returns a list of users as an arrayref containing hashrefs.
378 =item user_entry($id)
380 Returns a hashref with information about the user $id.
382 =item problem_list([%args])
384 Returns a list of problems grouped by level. A hashref with levels as keys.
386 Takes the following arguments:
392 Only show problems owned by this user
396 Only show problems in this contest
400 =item problem_entry($id, [$contest, $user])
402 Returns a hashref with information about the problem $id. If $contest and $user are present, problem open data is updated.
404 =item contest_list([%args])
406 Returns a list of contests grouped by state. A hashref with the following keys:
412 An arrayref of hashrefs representing pending contests
416 An arrayref of hashrefs representing running contests
420 An arrayref of hashrefs representing finished contests
424 Takes the following arguments:
430 Only show contests owned by this user.
434 =item contest_entry($id)
436 Returns a hashref with information about the contest $id.
438 =item job_list([%args])
440 Returns a list of jobs as an arrayref containing hashrefs. Takes the following arguments:
446 Only show jobs submitted by this user.
450 Only show jobs submitted in this contest.
454 Only show jobs submitted for this problem.
458 Show this page of results. Defaults to 1. Pages have 10 entries, and the first page has the most recent jobs.
464 Returns a hashref with information about the job $id.
