【问题描述】:
好的,所以我目前已经在 3 个表上建立了一对多对一的关系:
食谱-产品食谱-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,因此我的所有 setter/getters/_construct/_tostring 都已就位。
现在我已经完成了所有这些设置(它自己就可以正常工作)我希望用户能够从配方表单将新产品添加到配方中。所以我在食谱表格中做了一个表格的集合。
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,));
}
连接到这个表单:
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);
到目前为止一切顺利,表单创建良好,并且可以很好地保存到数据库中。但是,在我的 Many 表中,Recipe_ID 字段未填充当时正在创建的配方。如何在持久性上填写该字段?否则,用户正在创建一个配方并将产品添加到该配方中,但是当我坚持时,我只有一个没有产品的新配方和一组未连接到配方的产品数量。
对不起,如果我以一种令人困惑的方式写了这篇文章......这是因为我自己也很困惑。

只是为了提供一点帮助,我将添加我的控制器代码,稍微精简一下:
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;
}
还有我的 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;
}

所以在 Cerad 的建议下,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(),
));
}
还是没用……

现在可以了,我的问题是我在 newAction 中的大部分内容应该在 createAction 中。完美运行。谢谢塞拉德。
