php - codeigniter where to process sql result? -

class selectedmodel extends ci_model {      var $title   = 'selectedmodel';     var $content = 'get top n articles';     var $date    = '23.2.2011';      function __construct()     {         parent::__construct();     }      function gettoparticles()     {        $result = $this->db->query('select top 5 article articles;');        if( ! $result->num_rows() > 0 )            die('there no articles in db.');         return $result;     } }   class front extends ci_controller {      function __construct()     {         parent::__construct();     }      function index()     {         $this->load->database();         $this->load->helper(array('text', 'html'));         $this->load->model('selectedmodel');          // controller process data , validate         $top_articles = $this->selectedmodel->gettoparticles();         foreach($top_articles->result() $item)         {             $item->desc = character_limiter($item->desc, 75);             if( strlen($item->image) == 0 )                 $item->desc = '/images/default.png';          }           $data['title'] = 'title';         $data['random_articles'] = $top_articles;         $this->load->view('front', $data);     } }

front view:

php foreach($random_articles->result() $item):     php echo $item->desc     php echo br() . $item->image php endforeach;

i'm wondering if knowledge of mvc correct. in controller process data, prepare them show them in view. in view there room html/css code , echo $var.. model function data.

are there other approaches process data. way ok?

optimization issue: $top_articles = $this->selectedmodel->gettoparticles(); don't know how php manages line. i'm asking if $top_articles copy of gettoparticles, use twice many memory if use in view:

front view:

php foreach($random_articles->result() $item):     php echo character_limiter($item->desc, 75)     php echo br() . if( strlen($item->image) == 0 ) echo images/default.png''; else echo $item->image; php endforeach;

but approach don't use mvc(using character_limit, .... in view).

i think got idea down. mvc approach doesn't mean better optimized.

generating data in model, passing controller, , view correct way this, though seem though view many lines of code.

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.
