Fetch data from textfield

Rails
1

i am unable for write query corresponding to text_field value…
The code is:
class MainController < ApplicationController
def search

 book=Book.find_by_book_id(params[:query])



 redirect_to :controller=>'search',:action=>'sv',:id=>@book
  end
end
2 
 book=Book.find_by_book_id(params[:query])

Try it :

   @book=Book.find_by_book_id(params[:query])

By creating instance variable it will be accessible to your query field.
