228 Gruntmaster::Data is the interface to the Gruntmaster 6000 database. Read the L<DBIx::Class> documentation for usage information.
230 In addition to the typical DBIx::Class::Schema methods, this module contains several convenience methods:
236 Equivalent to C<< $schema->resultset('Contest') >>
238 =item contest_problems
240 Equivalent to C<< $schema->resultset('ContestProblem') >>
244 Equivalent to C<< $schema->resultset('Job') >>
248 Equivalent to C<< $schema->resultset('Problem') >>
252 Equivalent to C<< $schema->resultset('User') >>
256 Equivalent to C<< $schema->resultset('Contest')->find($id) >>
260 Equivalent to C<< $schema->resultset('Job')->find($id) >>
264 Equivalent to C<< $schema->resultset('Problem')->find($id) >>
268 Equivalent to C<< $schema->resultset('User')->find($id) >>
272 Returns a list of users as an arrayref containing hashrefs.
274 =item user_entry($id)
276 Returns a hashref with information about the user $id.
278 =item problem_list([%args])
280 Returns a list of problems grouped by level. A hashref with levels as keys.
282 Takes the following arguments:
288 Only show problems owned by this user
292 Only show problems in this contest
296 =item problem_entry($id, [$contest, $user])
298 Returns a hashref with information about the problem $id. If $contest and $user are present, problem open data is updated.
300 =item contest_list([%args])
302 Returns a list of contests grouped by state. A hashref with the following keys:
308 An arrayref of hashrefs representing pending contests
312 An arrayref of hashrefs representing running contests
316 An arrayref of hashrefs representing finished contests
320 Takes the following arguments:
326 Only show contests owned by this user.
330 =item contest_entry($id)
332 Returns a hashref with information about the contest $id.
334 =item job_list([%args])
336 Returns a list of jobs as an arrayref containing hashrefs. Takes the following arguments:
342 Only show jobs submitted by this user.
346 Only show jobs submitted in this contest.
350 Only show jobs submitted for this problem.
354 Show this page of results. Defaults to 1. Pages have 10 entries, and the first page has the most recent jobs.
360 Returns a hashref with information about the job $id.
