![]() ![]() (If you need to test the upgrade script without changing the plugin version, it is also possible to set back the version number in the mdl_block or mdl_modules table in the database.) To run the upgrade scripts, log in to Moodle as administrator, navigate to the site home page, and follow the instructions. It is necessary to bump up plugin version number after any change in db/access.php, so that the upgrade scripts can make the necessary changes to the database. In releases before May 2012 clonepermissionsfrom works only inside individual plugins or only in core, in later releases plugins may also clone permissions from core, success of other cloning operations depends on upgrade order.The full syntax is: 'clonepermissionsfrom' => 'moodle/quiz:attempt', This may give better defaults than just using archetypes for administrators who have heavily customised their roles configuration. clonepermissionsfrom - when you are adding a new capability, you can tell Moodle to copy the permissions for each role from the current settings for another capabilty.Archetypes are defined in mdl_role table. archetypes - specifies defaults for roles with standard archetypes, this is used in installs, upgrades and when resetting roles (it is recommended to use only CAP_ALLOW here).'moodle/site:accessallgroups' - could be checked with CONTEXT_MODULE). This capability can be checked with contexts that are at a lower level (e.g. Declares the typical context level where this capability is checked. contextlevel - specified as context level constant.captype - read or write capability type, for security reasons system prevents all write capabilities for guest account and not-logged-in users. ![]() These are explained on Hardening new Roles system. The name of the capability consists of "plugintype/pluginname:capabilityname". How to define new capabilities in pluginsĬapabilities are defined by $capabilities array defined in db/access.php files. All other authenticated users get the default user role specified in $CFG->defaultuserroleid and in the frontpage context the role specified in $CFG->defaultfrontpageroleid. Again you can not assign any roles to the guest account directly, this account gets the $CFG->guestroleid automatically. There is one special guest user account that is used when user logs in using the guest login button or when guest autologin is enabled. User access control is calculated from the definitions of roles assigned to users.Īll users that did not log-in yet automatically get the default role defined in $CFG->notloggedinroleid, it is not possible to assign any other role to this non-existent user id. Role definitions can be overridden at lower context levels. Roles are defined at the top most system context level. Role is a set of capability definitions, each capability usually represents an ability of user to do something. Most entities in Moodle (system, users, course categories, courses, modules and blocks) are represented by contexts that are arranged in a tree like hierarchy called context tree. ![]() Moodle is using a role based access control model.
