mysql doesn't work with Ruby on Rails

Question

Hi I am new to Ruby on Rails. I created a new project using Aptana Studio and started the server using rails server command. But when I'm trying to access the server via browser I'm getting the following error.

https://i.sstatic.net/7P0FE.png

Access denied for user root@localhost (using password: NO)


      socket = socket.to_s unless socket.nil?

      connect user, pass, host, port, database, socket, flags
    end

def self.default_query_options

Rails.root: /home/tapas/RubyWorkspace/myproj

I tried using all host:port combinations e.g. 3000,3306..etc ,but nothing works. And here's how my database.yml file looks like.

https://i.sstatic.net/a9ok1.png

development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: mysql_dev
  pool:5
  username: root
  password: tapaskumar
  socket: /var/run/mysqld/mysqld.sock
  host: localhost
  port: 3306

test:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: mysql_test
  pool: 5
  username: root
  password: tapaskumar
  socket: /var/run/mysqld/mysqld.sock
  host: localhost
  port: 3306

production:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: mysql2_prod
  pool: 5
  username: root
  password: tapaskumar
  socket: /var/run/mysqld/mysqld.sock
  host: localhost
  port: 3306

When I'm trying to access mysql from terminal, it works fine. Also I installed mysql using this command.

sudo apt-get install mysql-server mysql-client libmysqlclient-dev

And also have the mysql gem installed for the project. I'm unable to figure out whats wrong.

Answer 1

I was editing some global database.yml file previously .Then i found out a specific database.yml file on config folder of the project directory ,which i think is specific to that project.After few indentation errors ,Finally got it.
