ruby on rails - rake db:migrate issue postgresql -

i'm complete noob @ postgresql, ruby on rails..

i'm trying follow tutorial (without rubymine) http://www.codeproject.com/articles/575551/user-authentication-in-ruby-on-rails#installingrubymine4

i have such migrate (001_create_user_model.rb):

class createusermodel < activerecord::migration   def self.up     create_table :users |t|       t.column :username, :string       t.column :email, :string       t.column :password_hash, :string       t.column :password_salt, :string     end   end    def self.down     drop_table :users   end end 

---

the error i'm getting goes this:

syntax error, unexpected ':', expecting ';' or '\n'         t.column...sers |t|  ... c:131071:in 'disable_dll_transaction' task:top => db:migrate 

what this:

class createusermodel < activerecord::migration   def self.up     create_table :users |t|       t.string :username, :null => false       t.string :email,:null => false       t.string :password_hash, :null => false       t.string :password_salt, :null => false       t.timestamps     end   end    def self.down     drop_table :users   end end
