Error using has_capability function

Error using has_capability function

I am using moodle 2.2.

I have a custom block called instructors located beneath the blocks folder blocks\instructors

I have experimented with the has_capability() function, but keep getting the message "Capability "blocks/instructors:manager_view" was not found". 

I have a db folder beneath the instructors folder that contains a access.php file that includes this

    'block/instructors:manager_view' => array(
        'captype' => 'read',
        'contextlevel' => CONTEXT_BLOCK,
        'legacy' => array(
            'manager' => CAP_ALLOW
        )
    ),

I have incremented the version.php # located in the instructors folder, visited notifications but still get the message..

Capability "blocks/instructors:manager_view" was not found! This has to be fixed in code.

  • line 370 of \lib\accesslib.php: call to debugging()
  • line 43 of \blocks\instructors\index.php: call to has_capability()

Please help, frustrated.

after adding version.php, did you go to .../admin/index.php to let moodle update itself?

Tim, I incremented the version.php file again, saved, Saw the plugins check form, saw my block indicating that it was going to update, clicked Update, which returned me to the admin root saying successful.

Entered my block and still see the same message.

Capability "blocks/instructors:manager_view" was not found! This has to be fixed in code.

  • line 370 of \lib\accesslib.php: call to debugging()
  • line 43 of \blocks\instructors\index.php: call to has_capability()

Clicked the Notifications link, just for good measure - but did not do anything since update was already done.

OK, so it sounds like you are doing everything correctly.

You should probably have a quick look in the mdl_capabilities table, to see if your capability is there, but it probably isn't.

Also, I wonder if _ is allowed in capability names. It might not be. Try renaming your capability to blocks/instructors:managerview

You meant "block/instructors:manager_view", right? Also the "_" in capability name is a bit unusual.

ahhh, that was it the 's' at the end of blocks...I guess I included the 's' since the directory structure is blocks.  thanks for that catch.

It did not mind the _ underscore in the name

The rule was in the DB table.

@Tim, thanks for your help too.

The fact that the folder is called blocks, not block, is the problem. For all other plugins, the containing folder is singular (mod, report, question/type, ...) It has been like that for so long that it is basically impossible to change blocks -> block now. You just have to live with it.
