我有以下表格
请查看此sqlfiddle以获取详细信息http://sqlfiddle.com/#!2/eb1c73/24/0
我可以在我的产品型号上使用类似的内容来获取像我在sqlfiddle查询中所做的所有属性吗?
function attributes(){
return $this->hasManyThrough('Attributes','Variant');
}
谢谢! 我的模特:
<?php
class Product extends \Eloquent {
protected $table = 'products';
public function user()
{
return $this->belongsTo('User');
}
public function variants()
{
return $this->hasMany('Variant');
}
public function attributes(){
return $this->hasManyThrough('Attribute','OptionVariant');
}
}
<?php
class Variant extends \Eloquent {
protected $table = 'variants';
public function product()
{
return $this->belongsTo('Product');
}
public function options()
{
return $this->belongsToMany('Option');
}
}
<?php
class Attribute extends \Eloquent {
protected $table = 'attributes';
public function options()
{
return $this->hasMany('Option');
}
}
<?php
class Option extends \Eloquent {
protected $table = 'options';
public function attribute()
{
return $this->belongsTo('Attribute');
}
public function variants()
{
return $this->belongsToMany('Variant');
}
}
<?php
class OptionVariant extends \Eloquent {
protected $table = 'option_variant';
}

如果您想要选择产品的所有属性:
在产品型号中:
$with = ['attributes'];
在控制器中:
$products = $this->product->findAll();
return View::make('products.index', compact('products'));
在视图中:
@foreach($products as $product)
{{ $product->attributes->column1 }}
@endforeach
