Odoo - Filter child records in parent class

Question

I am using Odoo 10-e. I am working on a sample module. I have 5 models (customer, product, order, order details, movement)

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

What i am trying to do is, i am creating a movement form in which user will select a customer from customer drop down first then user will add order_lines and in that he will be able to add products i want to filter products which are associated with above selected customer . How can i do that ? I have been trying since last month.

Can you please update your question with your view of "amgl.metal_movement" model? — Chavada Viki

Thank you for updation of question.

First add customer in product field context.

<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>

Then in product's model write it's name_get method like this.

@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

Thats it.
