234 Gruntmaster::Data is the interface to the Gruntmaster 6000 database. Read the L<DBIx::Class> documentation for usage information.
236 In addition to the typical DBIx::Class::Schema methods, this module contains several convenience methods:
242 Equivalent to C<< $schema->resultset('Contest') >>
244 =item contest_problems
246 Equivalent to C<< $schema->resultset('ContestProblem') >>
250 Equivalent to C<< $schema->resultset('Job') >>
254 Equivalent to C<< $schema->resultset('Problem') >>
258 Equivalent to C<< $schema->resultset('User') >>
262 Equivalent to C<< $schema->resultset('Contest')->find($id) >>
266 Equivalent to C<< $schema->resultset('Job')->find($id) >>
270 Equivalent to C<< $schema->resultset('Problem')->find($id) >>
274 Equivalent to C<< $schema->resultset('User')->find($id) >>
278 Returns a list of users as an arrayref containing hashrefs.
280 =item user_entry($id)
282 Returns a hashref with information about the user $id.
284 =item problem_list([%args])
286 Returns a list of problems grouped by level. A hashref with levels as keys.
288 Takes the following arguments:
294 Only show problems owned by this user
298 Only show problems in this contest
302 =item problem_entry($id, [$contest, $user])
304 Returns a hashref with information about the problem $id. If $contest and $user are present, problem open data is updated.
306 =item contest_list([%args])
308 Returns a list of contests grouped by state. A hashref with the following keys:
314 An arrayref of hashrefs representing pending contests
318 An arrayref of hashrefs representing running contests
322 An arrayref of hashrefs representing finished contests
326 Takes the following arguments:
332 Only show contests owned by this user.
336 =item contest_entry($id)
338 Returns a hashref with information about the contest $id.
340 =item job_list([%args])
342 Returns a list of jobs as an arrayref containing hashrefs. Takes the following arguments:
348 Only show jobs submitted by this user.
352 Only show jobs submitted in this contest.
356 Only show jobs submitted for this problem.
360 Show this page of results. Defaults to 1. Pages have 10 entries, and the first page has the most recent jobs.
366 Returns a hashref with information about the job $id.
