Question

I’m getting the following problem with my functional test.

mrbernz:mylife bernardleung$ ruby test/functional/forums_controller_test.rb
…..

1) Error:
test_should_create_forum(ForumsControllerTest):
ActiveRecord::StatementInvalid: Mysql::BadFieldError: Unknown column ‘id:3 name’ in ‘field list’: INSERT INTO roles (id, id:3 name) VALUES (707834473, ‘Moderator’)

A stack trace of the error points as follows…

My forums_controller_test.rb looks as follows (first few lines anyway)

require File.dirname(__FILE__) + '/../test_helper'

class ForumsControllerTest < ActionController::TestCase
  fixtures :forums, :users, :roles, :roles_users

  test "should get index" do
    get :index
    assert_response :success
    assert_not_nil assigns(:forums)
  end

I don’t understand why it’s complaining about ‘roles_user’ as I don’t ask for it anywhere, and what I do ask for or declare is ‘roles_users’ which is a table I do have!

Answer 1

Remove :roles_users from the fixtures declaration in ForumsControllerTest.
By specifying :roles_users as a fixture it is trying to load a model called RolesUser. I’m assuming it is a has_and_belongs_to_many join table.

Make sure your users.yml fixture has:

user:
 roles: moderator

and your roles.yml fixture has:

moderator:
 name: 'Moderator'

and that id values are not set in the user.yml or roles.yml files.
