php - Zend_Navigation: Getting Only the Pages Accessible by the Current User/Role -

-

i have zend_navigation running data provided navigation.xml file. let's assume first level (0) consists of 2 pages, frontend , backend. frontend accessible guest role, backend admin role.

if a

<?php echo $this->navigation()->menu()->setmaxdepth(0); ?>

it correctly displays "frontend" link when not logged in, , both "frontend" , "backend" links when logged in admin.

however, displaying "frontend" link doesn't make sense guests, because don't have other pages navigate on level anyway. rather not display navigation @ guests.

i know do

<?php if ('guest' !== $this->view->role) {     echo $this->navigation()->menu(); } ?>

but i'm hoping better way this.

what i'm looking like

<?php if (count($this->navigation()->getpagesforrole($this->view->role)) > 1) {     echo $this->navigation()->menu(); } ?>

i can't figure out how achieve api provided zend_navigation... see there getpages() method, returns pages "unfiltered".

i assume there easy solution this, i've been trying figure out past 2 hours , found nothing, guess i'm looking in wrong direction.

thanks time.

edit:

i forgot mention navigation using acl control privileges, , it's working fine. problem not want display frontend/backend navigation guests, because navigation of 1 link item pretty useless. sorry confusion.

zend navigation requires zend_acl instance achieve that. have adjust navigation config include resource/privilege information, e.g.

$navarray = array( …,      array(        'module' => 'admin',        'label' => 'administration',        'resource' => 'admin',        'privilege' => 'index',        'pages' => array(      … );

see http://framework.zend.com/manual/en/zend.navigation.containers.html

then need set acl defining access restrictions resources , privileges.

  $acl = new zend_acl();   $acl->addrole(new zend_acl_role('user'))       ->addrole(new zend_acl_role('admin'));    …

see http://framework.zend.com/manual/en/zend.acl.introduction.html

your acl has set navigation helper, along role of current user

$this->gethelper('navigation')     ->setacl($acl)     ->setrole('user');

after that, calls helper api should aware of acl. in above example, admin menu should not rendered, if user disallowed access in acl.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
