If you have a line in ProductsController#index like:
@products = Product.find(:all)
Then of course you'll see all products. The question is what you want
to see at that url. I'd expect to see all the products in category 7
def index
if find_category
@products = @category.products
else
flash[:error] = "No category with id=#{params[:category_id]}"
redirect_to categories_path
end
end
def find_category
@category = Category.find_by_id(params[:category_id])
end
And you can even put the find_category into a before_filter and
redirect from it directly.
