331 =head1 DESCRIPTION
332
333 Gruntmaster::Data is the interface to the Gruntmaster 6000 database. Read the L<DBIx::Class> documentation for usage information.
334
335 In addition to the typical DBIx::Class::Schema methods, this module contains several convenience methods:
336
337 =over
338
339 =item contests
340
341 Equivalent to C<< $schema->resultset('Contest') >>
342
343 =item contest_problems
344
345 Equivalent to C<< $schema->resultset('ContestProblem') >>
346
347 =item jobs
348
349 Equivalent to C<< $schema->resultset('Job') >>
350
351 =item problems
352

354
355 =item users
356
357 Equivalent to C<< $schema->resultset('User') >>
358
359 =item contest($id)
360
361 Equivalent to C<< $schema->resultset('Contest')->find($id) >>
362
363 =item job($id)
364
365 Equivalent to C<< $schema->resultset('Job')->find($id) >>
366
367 =item problem($id)
368
369 Equivalent to C<< $schema->resultset('Problem')->find($id) >>
370
371 =item user($id)
372
373 Equivalent to C<< $schema->resultset('User')->find($id) >>
374
375 =item user_list
376
377 Returns a list of users as an arrayref containing hashrefs.
378
379 =item user_entry($id)
380
381 Returns a hashref with information about the user $id.
382
383 =item problem_list([%args])
384
385 Returns a list of problems grouped by level. A hashref with levels as keys.
386
