Odoo - 在父類中篩選子記錄

Question

我正在使用Odoo 10-e。我正在研究一個示例模塊。 我有5款（客戶，產品，訂單，訂單明細，運動）

Customer :

class Customer(models.Model): 
    _name ="amgl.customer" 
    …… all other fields related to customer 
    product_ids = fields.Many2many('amgl.products', string='Products') 

Products :

class Products(models.Model): 
    _name ="amgl.products" 
    …… all other fields related to product 
    customer_ids = fields.Many2many('amgl.customer', string='Customers') 

Order :

class Order(models.Model): 
    _name ="amgl.order" 
    order_line = fields.One2many('amgl.order_line', 'order_id', string='Order Lines') 
    …… all other fields related to Order 

Order Details :

class OrderLine(models.Model): 
    _name = 'amgl.order_line' 

    order_id = fields.Many2one('amgl.order', string='Orders') 
    products = fields.Many2one('amgl.products', string="Products") 
    …… all other fields related to order details 

Movement

class Movement(models.Model): 
    _name = 'amgl.metal_movement' 

    customer = fields.Many2one("amgl.customer", string="Customer", required=True) 
    order_lines = fields.One2many('amgl.order_line','metal_movement_id') 

    …… all other fields related to movement 

什麼，我試圖做的是，我創建一個運動形式，其中用戶將選擇從客戶的客戶下拉首先用戶將添加order_lines，並且他將能夠添加我想要過濾產品的產品，這些產品是相關的與上面選定的客戶一起。我怎樣才能做到這一點 ？自上個月以來我一直在嘗試。

Answer 1

謝謝你的問題的更新用。

首先在產品領域上下文中添加客戶。

<field name="order_lines"> 
    <tree editable="bottom"> 
     <field name="quantity" string="Quantity"/> 
     <field name="products" context="{'customer_id':parent.customer}" string="Product Name"/> 
     <field name="weight" string="Weight"/> 
     <field name="total_weight" string="Total Weight"/> 
    </tree> 
</field> 

然後在產品的模型中寫入它的name_get方法就像這樣。

@api.multi 
def name_get(self): 
    if self.env.context('customer_id',False): 
     customer = self.env['amgl.customer'].browse(self.env.context('customer_id',False)) 
     for product in customer.product_ids: 
      res.append((product.id,product.name)) 
    else: 
     res=super(product_product,self).name_get() 
    return res 

那就是它。
