Class: course_enrolments - X-Ref
Base class for targets whose analysable is a course using user enrolments as samples.| get_analyser_class() X-Ref |
| Returns the analyser class that should be used along with this target. return: string The full class name as a string |
| can_use_timesplitting(\core_analytics\local\time_splitting\base $timesplitting) X-Ref |
| Only past stuff. param: \core_analytics\local\time_splitting\base $timesplitting return: bool |
| get_insight_subject(int $modelid, \context $context) X-Ref |
| Overwritten to show a simpler language string. param: int $modelid param: \context $context return: string |
| get_insight_body(\context $context, string $contextname, \stdClass $user, \moodle_url $insighturl) X-Ref |
| Returns the body message for the insight. param: \context $context param: string $contextname param: \stdClass $user param: \moodle_url $insighturl return: string[] The plain text message and the HTML message |
| is_valid_analysable(\core_analytics\analysable $course, $fortraining = true) X-Ref |
| Discards courses that are not yet ready to be used for training or prediction. param: \core_analytics\analysable $course param: bool $fortraining return: true|string |
| is_valid_sample($sampleid, \core_analytics\analysable $course, $fortraining = true) X-Ref |
| Discard student enrolments that are invalid. Note that this method assumes that the target is only interested in enrolments that are/were active between the current course start and end times. Targets interested in predicting students at risk before their enrolment start and targets interested in getting predictions for students whose enrolment already finished should overwrite this method as these students are discarded by this method. param: int $sampleid param: \core_analytics\analysable $course param: bool $fortraining return: bool |
| prediction_actions(\core_analytics\prediction $prediction, $includedetailsaction = false,$isinsightuser = false) X-Ref |
| prediction_actions param: \core_analytics\prediction $prediction param: bool $includedetailsaction param: bool $isinsightuser return: \core_analytics\prediction_action[] |
| bulk_actions(array $predictions) X-Ref |
| Suggested bulk actions for a user. param: \core_analytics\prediction[] $predictions List of predictions suitable for the bulk actions to use. return: \core_analytics\bulk_action[] The list of bulk actions. |
| add_bulk_actions_js() X-Ref |
| Adds the JS required to run the bulk actions. |
| enrolment_active_during_analysis_time(int $sampleid, int $starttime, int $endtime) X-Ref |
| Is/was this user enrolment active during most of the analysis interval? This method discards enrolments that were not active during most of the analysis interval. It is important to discard these enrolments because the indicator calculations can lead to misleading results. Note that this method assumes that the target is interested in enrolments that are/were active during the analysis interval. Targets interested in predicting students at risk before their enrolment start should not call this method. Similarly, targets interested in getting predictions for students whose enrolment already finished should not call this method either. param: int $sampleid The id of the sample that is being calculated param: int $starttime The analysis interval start time param: int $endtime The analysis interval end time return: bool |
