php - CakePHP Entity contain without foreign key -


i have entity villa, , want entity contain other villas have same 'complex' (varchar(255)).

class villastable extends table {      /**      * initialize method      *      * @param array $config configuration table.      * @return void      */     public function initialize(array $config)     {         $this->table('villas');         $this->displayfield('name');         $this->primarykey('id');          $this->hasmany('complexs', [             'classname' => 'villas',             'foreignkey' => false,             'propertyname' => 'complexs',             'conditions' => ['complexs.complex' => 'villas.complex']         ]);     } } ?>

i don't know if it's possible. don't want add find in each function need entity. make function in entity uses new field. ``

despite fact using varchar(255) foreign key highly inefficient and/or require huge indices, guess option defines foreign key of other table come in handy here, similar targetforeignkey belongstomany associations. may want suggest enhancement.

result formatters

currently doesn't seem possible out of box using associations, you'd have select , inject associated records yourself, example in result formatter.

$villas     ->find()     ->formatresults(function($results) {         /* @var $results \cake\datasource\resultsetinterface|\cake\collection\collection */          // extract custom foreign keys results         $keys = array_unique($results->extract('complex')->toarray());          // find associated rows using extracted foreign keys         $villas = \cake\orm\tableregistry::get('villas')             ->find()             ->where(['complex in' => $keys])             ->all();          // inject associated records results         return $results->map(function ($row) use ($villas) {             if (isset($row['complex'])) {                 // filters associated records based on custom foreign keys                 // , adds them property on row/entity                 $row['complexs'] = $villas->filter(function ($value, $key) use ($row) {                     return                         $value['complex'] === $row['complex'] &&                         $value['id'] !== $row['id'];                 })                 ->toarray(false);             }             return $row;         });     });

this fetch associated rows afterwards using custom foreign keys, , inject results, you'd end associated records on entities.

see cookbook > database access & orm > query builder > adding calculated fields

there might other options, example using custom eager loader collects necessary keys, combined custom association class uses proper key stitching results together, see

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
