Filtering with conditions on an associations's association in CakePHP -



Filtering with conditions on an associations's association in CakePHP -

in app have burger model, joint model, , location model.

joints have many burgers, , have many locations.

what want filter burgers 2 ways: based on rating, , bases on whether belong joint has location matches condition, in case, city.

here's i've tried, no workey:

$burgers = $this->burger->find('all', array( 'conditions' => array('burger.official_rating !=' => 0), 'contain' => array( 'joint', 'joint.location.conditions' => array( 'location.city' => 'toronto' ) ), 'order' => array('burger.official_rating desc'), 'limit' => 10 ));

joint.location.conditions seems have no effect.

edit: using joins, unsure if efficient way (notice, had add together contain clause, create sure associated info returned in results).

$options['joins'] = array( array('table' => 'joints', 'alias' => 'joint1', 'type' => 'inner', 'conditions' => array( 'joint1.id = burger.joint_id' ) ), array('table' => 'locations', 'alias' => 'location2', 'type' => 'inner', 'conditions' => array( 'location2.joint_id = burger.joint_id' ) ) ); $options['conditions'] = array( 'location2.city' => 'toronto', 'burger.official_rating !=' => 0 ); $options['order'] = array( 'burger.official_rating desc', ); $options['limit'] = 10; $options['contain'] = array( 'joint','joint.location' ); $burgers = $this->burger->find('all', $options);

problem:

this mutual issue people have, remedied understand you cannot limit main find model based on conditions against it's contained items.

the reason can't because doing contain creates separate queries on tables, opposed join, creates single query.

solution:

your best bet in case utilize cakephp joins.

in cases (not yours), alternate using joins alter model you're doing query on. if need 1 condition, alter find model status instead of 1 within contain , contain in reverse order.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
