class ProductProduct(models.Model):

#api.multi
def action_view_pos_product(self):
OrderLine = self.env['pos.order.line']

# action['domain'] = [('product_id', 'in', products.ids)]
# action['context'] = {'': ,}
return action

Answer 1

You add action and call that action using button:
Step 1: you have to calculate total pos sale count using compute method:
class ProductProduct(models.Model):
_inherit = 'product.product'
#api.multi
def _pos_sales_count(self):
r = {}
domain = [
('state', 'in', ['sale', 'done']),
('product_id', 'in', self.ids),
]
for group in self.env['report.pos.order'].read_group(domain, ['product_id', 'product_qty'], ['product_id']):
r[group['product_id'][0]] = group['product_qty']
for product in self:
product.sales_count = r.get(product.id, 0)
return r
pos_sales_count = fields.Integer(compute='_pos_sales_count', string='#Pos Sales')
class ProductTemplate(models.Model):
_inherit = 'product.template'
#api.multi
#api.depends('product_variant_ids.pos_sales_count')
def _pos_sales_count(self):
for product in self:
product.pos_sales_count = sum([p.sales_count for p in product.product_variant_ids])
pos_sales_count = fields.Integer(compute='_pos_sales_count', string='#POS Sales')
Step 2 : define action to link pos order line related to product:
<record id="action_product_pos_sale_list" model="ir.actions.act_window">
<field name="name">Sale Order Lines</field>
<field name="res_model">pos.order.line</field>
<field name="context">{'search_default_product_id': [active_id], 'default_product_id': active_id}</field>
</record>
<record model="ir.ui.view" id="product_form_view_pos_sale_order_button">
<field name="name">product.product.pos.sale.order</field>
<field name="model">product.product</field>
<field name="inherit_id" ref="product.product_normal_form_view"/>
<field name="groups_id" eval="[(4, ref('sales_team.group_sale_salesman'))]"/>
<field name="arch" type="xml">
<div name="button_box" position="inside">
<button class="oe_stat_button" name="%(action_product_pos_sale_list)d"
type="action" icon="fa-usd">
<field string="Sales" name="pos_sales_count" widget="statinfo" />
</button>
</div>
</field>
</record>
