Dear all,
there are two tables ,one is product, one is location,
product has many location, and location belongs to product, all the
setting in the models i have done, now in the views/show.html.erb, i
want to display the product and its locations, usually we use
@product.locations to get all the locations, acturally,it finds all the
locations based on the id, but now, i have another column which is
item_id in both tables and works as foreign key, so now i want to show
the locations of the product where product.item_id=location.item_id ,
how to do this ?
Thanks
