   1  This files describes API changes for code that uses the question API.
   2  
   3  === 2.8 ===
   4  
   5  1) This is jsut a warning that some methods of the question_engine_data_mapper
   6     class have changed. All these methods are ones that you should not have been
   7     calling directly from your code, so this should not cause any problems.
   8     The changed methods are:
   9      * insert_question_attempt
  10      * insert_step_data
  11      * update_question_attempt_step
  12  
  13  
  14  === 2.7 ===
  15  
  16  1)  Changes to class question_bank_view:
  17  
  18      Filters, including $recurse and $showhidden, are now implemented as
  19      pluggable \core_question\bank\search\condition classes.
  20  
  21      Therefore $recurse and $showhidden are no longer passed to the following functions:
  22          protected function display_options [deprecated, use display_options_form()]
  23          protected function build_query_sql [deprecated, use build_query()]
  24  
  25      protected function display_category_form() is deprecated. Use \core_question\bank\search\category_condition
  26  
  27      protected function display_category_form_checkbox deprecated use html_writer::checkbox and separate JavaScript
  28  
  29  To add filters, local plugins can now implement the function local_[pluginname]_get_question_bank_search_conditions,
  30  
  31  2) To make columns available to question_bank_view, plugins can extend core_question\bank\column_base.
  32     Users may choose to display additional columns by setting $CFG->questionbankcolumns to a comma-delimited list of columns.
  33  
  34  3) The subsort separator has changed from _ to - in order to distinuguish subsorts vs frankenstyle component separators.
  35  
  36  4) Because of the move to autoloading, $knowncolumntypes and known_field_types() are no longer used.
  37  
  38  5) question_bank_column_base and it's derived classes have been namespaced to core_question\bank\column_base.
  39  
  40  
  41  === 2.6 ===
  42  
  43  1) Modules using the question bank MUST now declare their use of it with the xxx_supports()
  44     flag FEATURE_USES_QUESTIONS. question_module_uses_questions() should be used to determine
  45     if a module uses questions.
  46  
  47  2) It is sometimes necessary to display bits of question content without having
  48     and attempt (question_usage) in progress. Two examples of this are the option
  49     in the question bank to display the questiontext, and in the quiz statistics
  50     report, where it displays the question text above the report.
  51  
  52     Previously, this display was done using a special method that only worked for
  53     the question text, but which would not work for other parts of the question.
  54     That old mechanism has been deprecated, and there is a new method that you
  55     should use.
  56  
  57     To display the question, replace calls to question_rewrite_questiontext_preview_urls
  58     with calls to question_rewrite_question_preview_urls. Because the new function
  59     is more flexibile, you have to pass more arguments.
  60  
  61     To perform the necessary permission checks when the file is downloaded, you need
  62     to implement the callback [component name]_question_preview_pluginfile.
  63     (Previously you implemented [component name]_questiontext_preview_pluginfile.)
  64     quiz_statistics_question_preview_pluginfile is an example of what to do.
  65  
  66     question_send_questiontext_file has been deprecated. It is no longer necessary.
  67  
  68     To ensure you are no longer using or defining any deprecated functions,
  69     search for the regular expression:
  70     question_rewrite_questiontext_preview_urls|_questiontext_preview_pluginfile|question_send_questiontext_file
  71  
  72  3) The argument list for core_question_renderer::mark_summary has changed.
  73     Please update your calls. (The most likely scenario for this is if you have
  74     overridden core_question_renderer::info in your own renderer.) You need to
  75     make a change like:
  76     - $this->mark_summary($qa, $options);
  77     + $this->mark_summary($qa, $behaviouroutput, $options);
