properties of a n:m relation in doctrine
Hy guys
I've got the following schema for my objects:
Product:
columns:
name: { type: string(255) }
Basket:
columns:
current_status: { type: integer }
relations:
Products: { class: Product, refClass: BasketProducts, onDelete: CASCADE }
BasketProducts:
columns:
product_id: { type: integer, primary: true }
basket_id: { type: integer, primary: true }
quantity: { type: integer(4) }
relations:
Product: { local: product_id, onDelete: CASCADE }
Basket: { local: basket_id, onDelete: CASCADE }
Now in the frontend I 开发者_如何学编程try to show the users basket, getting the products by
foreach($basket->getProducts() as $product) {
echo $product->getId();
echo $product->getName();
}
The question now, how can i access the quantity field from the BasketProducts?
You will need to query the middle table directly in order to do this.
A good way to do this, is to add a function in your Basket.class.php that will retrieve the data you need based on a BasketID.
You could also create the function in your BasketTable.class.php if you'd like to include the data when fetching a particular basket (ie. getBasketWithProductQuantities())
I don't have any Doctrine code handy at this time.
