This files describes API changes for question behaviour plugins. === 3.1 === 1) The standard behaviours that use a 'Check' button have all been changed so that they only show the button when the question is active. Your behaviour may interit this behaviour, because the change was made in the base class, and this is probably good for consistency. However, if your question behaviour uses the Check button, your probably want to test it carefully, and you will probably have to update your unit tests. See MDL-53304 for more details. === 2.9 === 1) There are new methods question_behaviour::can_finish_during_attempt and question_behaviour_type::can_finish_during_attempt. These methods both return false by default. You should override it if, with your behaviour, questions may finish just through the student interacting with them (e.g. by clicking the Check button within the question). The behaviour type method answers the the question for this behaviour in general, without reference to a specific question. The method on the behaviour class answers the question for a specific attempt at a specific question. === 2.7 === 1) question_behaviour_type has a new method allows_multiple_submitted_responses which defaults to false but should return true if this question behaviour accepts multiple submissions of responses within one attempt eg. multiple tries for the interactive or adaptive question behaviours. question_behaviour has a new method step_has_a_submitted_response($step). For question behaviours where it is not only the final response that is submitted by the student, you need to override this method to return true for other steps where a student has submitted a response. See question_behaviour_with_multiple_tries::step_has_a_submitted_response($step) for example. This method only needs to be overriden if you are returning true from allows_multiple_response_submissions. === 2.6 === 1) Legacy required_question_definition_type no longer supported. (See 2.2 point 2) below.) 2) Behaviours now have to define an extra class class qbehaviour_mybehaviour_type extends question_behaviour_type { This class returns information about the type of behaviour, as opposed to the qbehaviour_mybehaviour class which controls a particular question_attempt. That is like the difference between the qtype_mytype and the qtype_mytype_question classes. Practically, what this means is that any of the methods that used to be static methods of qbehaviour_mybehaviour class are now normal instance methods of the qbehaviour_mybehaviour_type class. Specifically. 2.5 / qbehaviour_mybehaviour -> 2.6 / qbehaviour_mybehaviour_type IS_ARCHETYPAL -> is_archetypal() adjust_random_guess_score() -> adjust_random_guess_score() get_unused_display_options() -> get_unused_display_options() 3) The static method is_manual_grade_in_range has moved from the question_behaviour class to the question_engine class. 4) Behaviours can now control how the marks information is displayed in the grey info area to the left of the question. There is a new method mark_summary that you can override, although the default implementation is fine in most cases. it uses the marked_out_of_max and mark_out_of_max methods as appropriate, so you may just wish to override those. === 2.3 === 1) This plugin type now supports cron in the standard way. If required, Create a lib.php file containing function qbehaviour_mypluginname_cron() {}; === 2.2 === 1) The old public static function get_required_behaviours() method is no more. Instead use the ->dependencies facility in version.php. E.g. $plugin->dependencies = array( 'qbehaviour_immediatefeedback' => 2011102700, 'qbehaviour_deferredcbm' => 2011102700 ); 2) The old required_question_definition_type method has been replaced by a new is_compatible_question method. You should change your behaviour to override the new method, not the old one. This change has been implemented in a backwards-compatible way, so behaviours will not break.
