How to get product quantity

Question

I need to get product quantity on product onchange. There is a model stock_quant, which records all quantity activity.
How can I get the available quantity of the product? I am writing following function and getting stock_quantity lines but not sure how to filter out the available quantity -
@api.multi
@api.onchange('product_id')
def product_location_change(self):
if self.product_id:
stock_qty_obj = self.env['stock.quant']
stock_qty_lines = stock_qty_obj.search([['product_id', '=', self.product_

For All Warehouse this is how the quantity can be checked:
product = self.env['product.product'].browse(PRODUCT_ID)
available_qty = product.qty_available For specific warehouse/location:
product = self.env['product.product'].browse(PRODUCT_ID)
available_qty = product.with_context({'warehouse' : WAREHOUSE_ID}).qty_available
available_qty = product.with_context({'location' : LOCATION_ID}).qty_available
Other fields are:
Forecasted Stock => virtual_available
Incoming Stock => incoming

Add a loop to the stock lines:
def product_location_change(self):
if self.product_id:
stock_qty_obj = self.env['stock.quant']
stock_qty_lines = stock_qty_obj.search([['product_id', '=', self.product_id.id]])
print stock_qty_lines
# TODO: GET AVAILABLE QUANTITY OF THE PRODUCT
*available_quantity = 0
for row in stock_qty_lines:
available_quantity += row.quantity #change for your quantity field
print available_quantity
*
