My add_index command was producing no change in my MySQL 5.0 database:

add_index :designations, [ :scope_type, :scope_id, :role_id, :user_id ], :unique => true

By just adding an index name, the problem was solved:

add_index :designations, [ :scope_type, :scope_id, :role_id, :user_id ], :unique => true, :name => 'my_index'

This happens when the autogenerated index name gets too long. For more info see:

You can redirect to your main page using

redirect_to :root

Make sure to configure to root route first:

If you are using a non standard table name by means of set_table_name in your model:

class MyClassName < ActiveRecord::Base
  set_table_name "mytablename"
end

then you will get FixtureClassNotFound errors when you try to use fixtures in you unit tests. To solve this use set_fixture_class inside your test:

require 'test_helper'
class MyClassNameTest < ActiveSupport::TestCase
  set_fixture_class :mytablename => MyClassName  
end

and rename your fixture file to mytablename.yml

Just wanted to point out that you can also use the :format option:

url_for :controller=>'posts', :action=>'index', :format=>:xml

Results in:

"http://www.example.com/posts.xml"
