保存數據到數據庫

Question

我是CakePHP的新手，所以我的問題很容易回答。

我想創建一個表單，用於同時添加新配方和recipeitem。我怎麼做？

我有三個表在我的數據庫：食譜，recipeitems和recipes_recipeitems;

eg. Recipe.title 
    Recipe.cookingtime 
    Recipeitem.name 

我嘗試了以下操作，但它只創建了一個Recipepart而沒有設置它的名稱或recipe_id。

形式：

<?php echo $this->Form->create('Recipe'); ?> 
<fieldset> 
    <legend><?php echo __('Create recipe'); ?></legend> 
<?php 
    echo $this->Form->input('title'); 
    echo $this->Form->input('cooking_time'); 
    echo $this->Form->input('RecipeitemName'); 
?> 
</fieldset> 
<?php echo $this->Form->end(__('Submit')); ?> 

RecipeController：

App::import('model','RecipeItem'); 
class RecipesController extends AppController { 
public function add() { 
    if ($this->request->is('post')) { 
     $this->request->data['Recipe']['user_id'] = $this->Auth->user('id'); 
     $this->request->data['RecipeItem']['name'] = $this->request->data['Recipe']['RecipeitemName']; 
     $newRecipeItem = new RecipeItem(); 
     $this->Recipe->create(); 
     if ($this->Recipe->save($this->request->data)) { 
      $this->Session->setFlash(__('The recipe has been saved')); 
      //$this->redirect(array('action' => 'index')); 
     } else { 
      $this->Session->setFlash(__('The recipe could not be saved. Please, try again.')); 
     } 
     $this->request->data['RecipeItem']['recipe_id'] = $this->Recipe->id; 
     if ($newRecipeItem->save($this->request->data)) { 
      $this->Session->setFlash(__('The recipeItem has been saved')); 
      $this->redirect(array('action' => 'index'));    
     } else{ 
      $this->Session->setFlash(__('The recipeItem could not be saved. Please, try again.')); 
     } 

    } 
} 

Answer 1

$newRecipeItem = new RecipeItem(); 

此行是不是做你的想法。它創建RecipeItem類的一個實例。但它不會在數據庫中進行INSERT。所以這行：

$newRecipeItem->save($this->request->data) 

什麼都不做。你可以使用：

$this->Recipe->RecipeItem->create(); 

然後做一個保存。

create() function doc
