1 This files describes API changes in /availability/*.
3 The information here is intended only for developers.
7 * There were existing restrictions on what condition plugins can do in the get_description
8 method (for example they mustn't call format_string), which were not well documented.
9 New functions description_cm_name(), description_format_string(), description_callback()
10 can be used so that condition plugins to behave correctly in all situations.
14 * Condition plugins must replace the CSS selector "#fitem_id_availabilityconditionsjson" with ".availability-field".
15 This selector is often used in your plugin's yui/src/form/js/form.js file.
19 * Condition plugins can now implement a new include_after_restore function to
20 indicate that they should be removed during the restore process. (This is
21 implemented so that group and grouping conditions are removed if groups are
26 * There is a new API function in the info_module/info_section objects (and
27 related functions in internal API): get_user_list_sql. This returns SQL code
28 that does roughly the same as filter_user_list to return a list of users who
29 should be shown as having access to the module or section.
31 * Any third-party availability plugins which return true to
32 is_applied_to_user_lists (and therefore previously implemented
33 filter_user_list) should now also implement get_user_list_sql. If not
34 implemented, a debugging warning will occur when anybody calls
35 get_user_list_sql if the affected plugin is in use, and that user list will
36 not be filtered by the plugin.
