error with rails server command

Question

Can you point me to any good resources that show how to connect Sql Server to Rails app (Windows 7)?

I have done the following so far: rails new simple_cms –d sqlserver

gem install bundle

rails s

after the last command, this error is thrown:

PS: If I use sqlite as a database system, I am able to successfully start the webserver (no error). This probably means there's nothing wrong with my rails installation. I am guessing I might need to add sth to database.yml or write the database user and password somewhere. But how come this is not required with sqlite3? I also found this resource but not sure if still applicable (it refers to rails 2.0, whereas I use rails 4.1.1) http://rubyrailsandwindows.blogspot.de/2008/03/rails-2-and-sql-server-2008-on-windows_24.html - and some of the things there I tried but don't apply. Thanks in advance.

Later edit: I also tried rails s after editing the database.yml (from the config folder) to contain:

development:
  adapter: sqlserver
  encoding: unicode
  database: cms
  pool: 5
  username: guest1
  password: pwd1234%^&^
test:
  adapter: sqlserver
  encoding: unicode
  database: cms
  pool: 5
  username: guest1
  password: pwd1234%^&^
production:
  adapter: sqlserver
  encoding: unicode
  database: cms
  pool: 5
  username: guest1
  password: pwd1234%^&^

(of course, I also created previously a db called cms, and added a user called guest1 with the specified password, then made sure teh credentials worked to connect to the db by mimic-ing network connection from my local Sql Server itself)

After this new action I get a similar error as above:

C:\Sites\simple_cms>rails s
C:/Ruby193/lib/ruby/gems/1.9.1/gems/activesupport-.1.1/lib/active_support/core_ext/module/aliasing.rb:32:in `alias_method': undefined method `add_order!' for class `Class' (Name Error)

        ...............

This is a known bug with activerecord-sqlserver-adapter. It's being worked on but any fix has not yet been merged into a milestone.

It appears the workaround just now is to change your Gemfile to have:

gem 'activerecord-sqlserver-adapter', git: 'https://github.com/Desarrollo-CeSPI/activerecord-sqlserver-adapter.git'

Details of the issue are here and the efforts to fix it are here.
