Hello, I am a newbie Ruby developer.
I have an “Bookstore” application consisting of Books Prices.
In the Edit page, I am trying to associate Books with Price. The Books
and Prices has a has_one relationship and belongs_to relationship.
class Book < ActiveRecord::Base
belongs_to :price
end
class Price < ActiveRecord:Base
has_one :book
end
table book (
id int,
title varchar(20)
price_id int
);
table price (
id int
amount float
);
When I enter the Amount in the Edit page, I get the following
error:
Price(#-616403668) expected, got String(#-610120718)

How do I fix the error? Any help will be greatly appreciated,
