341 | ||
cbb36c78 MG |
342 | Gruntmaster::Data is the interface to the Gruntmaster 6000 database. Read the L<DBIx::Class> documentation for usage information. |
343 | ||
344 | In addition to the typical DBIx::Class::Schema methods, this module contains several convenience methods: | |
345 | ||
346 | =over | |
347 | ||
348 | =item contests | |
349 | ||
350 | Equivalent to C<< $schema->resultset('Contest') >> | |

353 | ||
354 | Equivalent to C<< $schema->resultset('ContestProblem') >> | |
355 | ||
356 | =item jobs | |
357 | ||

383 | ||
de625c9b MG |
384 | =item user_list |
385 | ||
386 | Returns a list of users as an arrayref containing hashrefs. | |
387 | ||
388 | =item user_entry($id) | |
389 | ||
390 | Returns a hashref with information about the user $id. | |
391 | ||
392 | =item problem_list([%args]) | |
393 | ||
394 | Returns a list of problems grouped by level. A hashref with levels as keys. | |
395 | ||
396 | Takes the following arguments: | |
397 | ||
398 | =over | |
399 | ||
400 | =item owner | |
401 | ||
402 | Only show problems owned by this user | |

405 | ||
406 | Only show problems in this contest | |
407 | ||
408 | =back | |
409 | ||
410 | =item problem_entry($id, [$contest, $user]) | |
411 | ||
412 | Returns a hashref with information about the problem $id. If $contest and $user are present, problem open data is updated. | |
413 | ||
