[Rails] cant convert integer to string

I''ve experimented around and have ran out of ideas, here''s the
message:

 TypeError in True_false_questions#list

can''t convert String into Integer

RAILS_ROOT: script/../config/..
Application Trace <http://zbyte32:3000/true_false_questions/list/0#> |
Framework
Trace <http://zbyte32:3000/true_false_questions/list/0#> | Full
Trace<http://zbyte32:3000/true_false_questions/list/0#>

./script/../config/../app/controllers/true_false_questions_controller.rb:9:in
`[]''

here''s the code snippet:


class TrueFalseQuestionsController < ApplicationController
  def index
    list
    render :action => ''list''
  end

  def list
    if params[:id]
      @true_false_question_pages, @true_false_questions = paginate
TrueFalseQuestion.find_all["tests_id = ?"+ params[:id]], :per_page
=> 10
    else
      @true_false_question_pages, @true_false_questions = paginate
:true_false_questions, :per_page => 10
    end
  end

basically vist the url: http://zbyte32:3000/true_false_questions/list/0

any suggestions would be much apreciated. Thank you.

[Rails] cant convert integer to string

I think you want:

if params[:id]
   @true_false_question_pages, @true_false_questions      paginate
TrueFalseQuestion.find( :all,
       :conditions => ["tests_id = ?", [params[:id]]]),
         :per_page => 10

Or better, if you''ve got the associations set up:

if params[:id]
   @true_false_question_pages, @true_false_questions      paginate
Test.find(params[:id]).true_false_questions,
       :per_page => 10

i couldn''t find what was wrong, but i tried a different approach and it
workd:

@true_false_question_pages, @true_false_questions = paginate
:true_false_questions, :conditions => ["tests_id = ?",
params[:id]],
:per_page => 10
