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