if you want to display the wordpress post to your rails website and you don't want to use mult-magic connection gem. you can use the below code in order to get the data from wordpress blog.

 class Article < ActiveRecord::Base

    ActiveRecord::Base.establish_connection(
     :adapter  => "mysql2",
     :host     => "localhost",
     :username => "root",
     :database => "blog"
    )

    self.table_name = 'wp_posts'

    def self.get_post_data()
        query = "select name from testing"
        tst = connection.select_all(query)
        tst[0].fetch('name')
    end
end
