php - cakePHP 3.0 HABTM relations save data -

i want make tutorial http://miftyisbored.com/complete-tutorial-habtm-relationships-cakephp/ in cakephp 3.0

i have 3 tables: recipes, ingredients , ingredients_recipes.

when making recipe, want select ingredients. want store recipe_id , ingredient_id in ingredients_recipes table, fail so. think there's wrong in recipescontroller. can me or point me in right direction?

problem:

$ingredients = $this->recipes->ingredients->find('list', ['limit' => 200]); // => gives me message "the recipe not saved. please, try again."  $ingredients = $this->ingredients->find('list', ['limit' => 200]); // => gives me error "call member function find() on boolean" 

when var dump (when using $this->recipes->ingredients->find) this:

array(3) {     ["recipe_name"]=> string(4) "test"     ["recipe_description"]=> string(4) "test"     ["recipe"]=> array(1) {        ["ingredient"]=> array(1) { [0]=> string(1) "1" }     }  } 

tables:

create table `recipes` (   `recipe_id` int(11) not null auto_increment,   `recipe_name` varchar(255) not null,   `recipe_description` text not null,   primary key  (`recipe_id`) ); create table `ingredients` (   `ingredient_id` int(11) not null auto_increment,   `ingredient_name` varchar(255) not null,   `ingredient_description` text not null,   primary key  (`ingredient_id`) ); create table `ingredients_recipes` (   `ingredient_id` int(11) not null,   `recipe_id` int(11) not null,   primary key  (`ingredient_id`,`recipe_id`) ); 

here's code below:

model > entity:

recipe

class recipe extends entity {     protected $_accessible = [         'recipe_id' => true,         'recipe_name' => true,         'recipe_description' => true,     ]; } 

ingredient

class ingredient extends entity {     protected $_accessible = [         'ingredient_id' => true,         'ingredient_name' => true,         'ingredient_description' => true,     ]; } 

ingredientsrecipe

class ingredientsrecipe extends entity {     protected $_accessible = [         'ingredient' => true,         'recipe' => true,     ]; } 

model > table :

recipestable

class ingredientstable extends table {     public function initialize(array $config)     {         $this->table('ingredients');         $this->displayfield('ingredient_name');         $this->primarykey('ingredient_id');          $this->belongsto('ingredients', [             'foreignkey' => 'ingredient_id',             'jointype' => 'inner'         ]);          $this->belongstomany('recipies', [             'classname' => 'recipies',             'jointable' => 'ingredients_recipes',             'foreignkey' => 'ingredient_id',             'targetforeignkey' => 'recipe_id'          ]);     } } 

ingredientsrecipestable

class ingredientsrecipestable extends table {     public function initialize(array $config)     {         $this->table('ingredients_recipes');          $this->displayfield('recipe_id');          $this->primarykey(['recipe_id', 'ingredient_id']);          $this->belongsto('recipies', [             'foreignkey' => 'recipe_id',             'jointype' => 'inner'         ]);          $this->belongsto('ingredients', [             'foreignkey' => 'ingredient_id',             'jointype' => 'inner'         ]);     } 

controller:

recipescontroller

public function add() {     $recipe = $this->recipes->newentity();     if ($this->request->is('post')) {         $recipe = $this->recipes->patchentity($recipe, $this->request->data);         // var_dump($this->request->data);         if ($this->recipes->save($recipe)){             $this->flash->success('the recipe has been saved.');             return $this->redirect(['action' => 'index']);         } else {             $this->flash->error('the recipe not saved. please, try again.');         }     }     $recipes = $this->recipes->find('list', ['limit' => 200]);      $ingredients = $this->recipes->ingredients->find('list', ['limit' => 200]);     // => gives me message "the recipe not saved. please, try again."     $ingredients = $this->ingredients->find('list', ['limit' => 200]);     // => gives me error "call member function find() on boolean"      $this->set(compact('recipe', 'recipes', 'ingredients'));     $this->set('_serialize', ['recipe']); } 

template > recipes

add.ctp

<?= $this->form->create($recipe); ?>     <fieldset>         <legend><?= __('add recipe') ?></legend>         <?php             echo $this->form->input('recipe_name', array(                 'label' => 'name'                 )             );             echo $this->form->input('recipe_description', array(                 'label' => 'description'                 )             );              echo $this->form->input('recipes.ingredients', ['multiple'=>true]);         ?>     </fieldset>     <?= $this->form->button(__('submit')) ?>     <?= $this->form->end() ?> 

maybe tutorial help: http://book.cakephp.org/3.0/en/tutorials-and-examples/bookmarks/intro.html.

it explains how set habtm relations, adding tags bookmarks, , more.

good luck , happy coding :)
