Question

好的，所以我目前在3个表上设置了一对多的关系：

食谱-ProductRecipe-产品

###Recipes.yml###
oneToMany:
    products:
      targetEntity: ProductRecipe
      mappedBy: recipes
      cascade: ["all"]

###ProductRecipe.yml###
manyToOne:
    products:
      targetEntity: Products
      inversedBy: recipes
    recipes:
      targetEntity: Recipes
      inversedBy: products

###Products.yml###
  oneToMany:
    recipes:
      targetEntity: ProductRecipe
      mappedBy: products
      cascade: ["all"]

我已经使用内置命令（doctrine：generate：entities）设置了这些实体，所以我已经准备好了所有的setter / getters / _construct / _tostring。

现在我已完成所有这些设置（它可以自行运行）我希望用户能够从配方表单中将新产品添加到配方中。所以我在食谱表格中制作了一系列表格。

class RecipesType extends AbstractType{
    public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('recipename')
        ->add('recipedesc')
        ->add('recipeyeild')
        ->add('recipecost');
    $builder->add('products', 'collection', array(
'type' => new ProductRecipeType(),
'allow_add'    => true,));
}

连接到此表单：

class ProductRecipeType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('ammount')
        ->add('products')
    ;
}

在我的食谱控制器中，我有这个：

public function newAction()
{
    $entity = new Recipes();
    $pr = new ProductRecipe();
    $entity->getProducts()->add($pr);
    $form   = $this->createCreateForm($entity);

到目前为止，表单已经很好地创建并且可以很好地保存到数据库中。但是在我的Many表中，Recipe_ID字段尚未填充当时正在创建的配方。如何填写该字段？否则，用户正在创建配方并将产品添加到配方中，但是当持久化时，我只需要一个没有产品的新配方和一个未连接到配方的产品ammounts集合。

很抱歉，如果我以一种令人困惑的方式写出来......那是因为我很困惑。

只是为了帮助我一点点添加我的控制器代码：

class Recipes
{
private $id;
private $recipename;
private $recipedesc;
private $recipeyeild;
private $recipecost;
public function __construct()
{
    $this->products = new \Doctrine\Common\Collections\ArrayCollection();
}
public function getId()
{
    return $this->id;
}
public function addProduct(\BC\InventoryBundle\Entity\ProductRecipe $pr)//<-this was $products
{
//$this->products[] = $products;  <-Original code now changed to below as suggested.

    $this->products->add($pr);
    $pr->setRecipes($this);    
    return $this;
}
public function removeProduct(\BC\InventoryBundle\Entity\ProductRecipe $products)
{
    $this->products->removeElement($products);
}
public function getProducts()
{
    return $this->products;
}

我的ProductRecipe实体：

class ProductRecipe
{
private $id;
private $ammount;
private $products;
private $recipes;
public function getId()
{
    return $this->id;
}
public function setAmmount($ammount)
{
    $this->ammount = $ammount;
    return $this;
}
public function getAmmount()
{
    return $this->ammount;
}
public function setProducts(\BC\InventoryBundle\Entity\Products $products = null)
{
    $this->products = $products;
    return $this;
}
public function getProducts()
{
    return $this->products;
}
public function setRecipes(\BC\InventoryBundle\Entity\Recipes $recipes = null)
{
    $this->recipes = $recipes;
    return $this;
}
public function getRecipes()
{
    return $this->recipes;
}

因此，在Cerad的建议之后我得到了这些......

//Recipes entity
 public function addProduct(\BC\InventoryBundle\Entity\ProductRecipe $products)
{

    $this->products->add($products);
    $products->setRecipes($this);

    return $this;
}


//Recipes Controller
public function newAction()
{
    $entity = new Recipes();
    $products = new ProductRecipe(); 

    $entity->getProducts()->add($products);
    $entity->addProduct($products);

    $form = $this->createCreateForm($entity);

    return $this->render('BCInventoryBundle:Recipes:new.html.twig', array(
        'entity' => $entity,
        'form'   => $form->createView(),
    ));
}

仍无济于事......

这就是现在我的问题是我在newAction中的大部分内容都应该在createAction中。完美的工作。谢谢塞拉德。

这是一个常见问题。您永远不会调用ProductRecipe :: setRecipe（）方法。可能也没有调用setProduct。

class Recipe
{
    public function addProduct($pr)
    {
        $this->products->add($pr);
        $pr->setRecipe($this); // *** This is what you need to add

在您的控制器中：

$entity->addProduct($pr);

虽然不直接相关，但请考虑将产品和配方更改为产品和配方。
