I keep getting this exception "SQLite3::SQLException: no such
column: books.user_id: SELECT "books".* FROM "books" WHERE
("books".user_id = 4)" ,which sounds like there is no user_id in books
table.So i just installed foreigner plugin and added "
t.integer :user_id, :null => false" and
"add_foreign_key(:books, :users)" in book migration and i ran "rake
db:migrate" but still it is giving me the same exception.I am using
Rails 3 in windows and devise to authenticate user.
HOME VIEW
<p><%= link_to "Add new Book",:controller =>"book", :action =>
'new' %></p>

<%end%>

class HomeController < ApplicationController

@user = current_user
@user.books||=Book.new
@books=@user.books

BOOK CONTROLLER
class BookController < ApplicationController

@books = Book.new
# redirect_to :controller=>"home" ,:action=>"index"

@books = Book.new(params[:book])
if @books.save
render "home/index"
#redirect_to :controller=>"home" ,:action=>"index"
else
render :action => 'new'
end
