MOODLE ROLES AND CAPABILITIES - moodle

Question

I had developed a block in 2.5. I installed the block successfully..and gave permissions settings on front end to view this block only for one role users say 'Manager'. So, Manager/Admin can only view this block and no one else.
But this block is still visible for all. Could you please judge me.. where I went wrong.. Here is my leisure block code
Blocks/block_leisure/block_leisure.php
<?php
class block_leisure extends block_base
{
public function init()
{
global $CFG;
$this->title = get_string('leisure', 'block_leisure');
}
public function get_content()
{
global $COURSE, $DB, $PAGE, $CFG, $USER, $CFG, $SESSION, $OUTPUT;
if ($this->content !== null)
{
return $this->content;
}
$this->content = new stdClass;
$context = $PAGE->context;
$this->content->text = 'This is a leisure block content';
$this->content->footer = 'Footer here...';
return $this->content;
} // Function - get_content().
public function getmodules()
{
return true;
}
}
Blocks/block_leisure/db/access.php
<?php
defined('MOODLE_INTERNAL') || die;
$capabilities = array(
'block/leisure:myaddinstance' => array(
'captype' => 'write',
'contextlevel' => CONTEXT_SYSTEM,
'archetypes' => array(
'user' => CAP_ALLOW
),
'clonepermissionsfrom' => 'moodle/my:manageblocks'
),
'block/leisure:addinstance' => array(
'riskbitmask' => RISK_SPAM | RISK_XSS,
'captype' => 'write',
'contextlevel' => CONTEXT_BLOCK,
'archetypes' => array(
'editingteacher' => CAP_ALLOW,
'manager' => CAP_ALLOW
),
'clonepermissionsfrom' => 'moodle/site:manageblocks'
),
'block/leisure:viewpages' => array(
'captype' => 'read',
'contextlevel' => CONTEXT_COURSE,
'legacy' => array(
'guest' => CAP_PREVENT,
'student' => CAP_ALLOW,
'teacher' => CAP_ALLOW,
'editingteacher' => CAP_ALLOW,
'coursecreator' => CAP_ALLOW,
'manager' => CAP_ALLOW
)
),
'block/leisure:managepages' => array(
'captype' => 'read',
'contextlevel' => CONTEXT_COURSE,
'legacy' => array(
'guest' => CAP_PREVENT,
'student' => CAP_PREVENT,
'teacher' => CAP_PREVENT,
'editingteacher' => CAP_ALLOW,
'coursecreator' => CAP_ALLOW,
'manager' => CAP_ALLOW
)
)
);
and as usual I have lang folder, version.php and read me file.

You need to do something with the capability you have defined, otherwise it will have no effect.
Check the capability within get_content, then return null if nothing should be displayed.
