There is a new method on the column class, for the column to declare any statistics it requires. The question then efficiently loads all those statistics in one go, and makes them available as the columns are rendererd, or do any subsequent processing.

This file describes core qbank plugin changes in /question/bank/*,
|
|
information provided here is intended especially for developers.
|
|
|
|
=== 4.2.1 ===
|
|
|
|
* There is a new more effecient way to display statistics in the question bank, you should now override
|
|
the get_required_statistics_fields() method in your column class, and then
|
|
the values you need will be available from $this->qbank->get_aggregate_statistic(...).
|
|
If you are not in a question_bank_column class, you can directly access efficient
|
|
statistics-loading from the core_question\local\statistics\statistics_bulk_loader class.
|
|
The old method will be deprecated in 4.3.
|
|
|
|
=== 4.1 ===
|
|
|
|
* New functions qbank_usage\helper::get_question_bank_usage_sql and
|
|
qbank_usage\helper::get_question_attempt_usage_sql have been implemented.
|
|
When calling a query with the SQL those methods returned, you have to be sure
|
|
in the accompanying $params array are in the right order.
|
|
|
|
=== 4.0 ===
|
|
|
|
* This plugin type is new in Moodle 4.0. It is for adding features to the question bank.
|
|
They key entry point is the class plugin_feature in the plugin namespace. This tells
|
|
the core question bank API exactly which features this plugin implements.
|
|
These features can currently be new columns in the question bank display, and bulk actions.
|
|
Currently, actions on single questions are implemented as a type of column (but this
|
|
should probably change in the future.) To get started, have a look at the methods
|
|
in core_question\local\bank\plugin_features_base which you can override.
