如何从 Laravel 中的 hasMany() 关系中获取所有结果

To get the children of the BaseProduct you may try this:

$bp = BaseProduct::with('Products')->get();

现在，你有BaseProduct个集合，所以，你可以使用这样的东西:

$bp->first()->products

Or get the second item from collection

$bp->get(1)->products

此外，您还可以像这样运行循环(最有可能在传递后的视图中):

// From the controller
$bp = BaseProduct::with('Products')->get();
return View::make('view_name')->with('baseProduct', $bp);

In the View

@foreach($baseProduct->products as $product)
    {{ $product->field_name }}
@endforeach

是的，你可以试试这个

$product = Product::first();
$baseProduct = $product->BaseProduct;

// Dump all children/products of this BaseProduct
dd($baseProduct->products->toArray());

You may chain like:

Product::first()->BaseProduct->products;

Update: Your table structure should look something like:

Table:baseproduct:

id(pk) | some_field | another_field

Table:products:

id(pk) | baseproduct_id(fk) | another_field

According to this table structure, relationship should be

// BaseProduct
public function Products()
{
    return $this->hasMany("Product");
}

// Product
public function Products()
{
    // second parameter/baseproduct_id is optional unless
    // you have used something else than baseproduct_id
    return $this->belongsTo("BaseProduct", "baseproduct_id");
}
