To setup root password for first time, use mysqladmin command at shell prompt as follows: $ mysqladmin -u root password NEWPASSWORD However, if you want to change (or update) a root password, then you need to use following command $ mysqladmin -u root -p'oldpassword' password newpass For example, If old password is abc, and set new password to 123456, enter: $ mysqladmin -u root -p'abc' password '123456' Change MySQL password for other user To change a normal user password you need to type (let us assume you would like to change password for vivek): $ mysqladmin -u vivek -p oldpassword password newpass Changing MySQL root user password using MySQL sql command This is another method.

The problem is that because you don’t know if @post.owner is a user or a group. Documentation : http://railsbrain.com/api/rails-2.3.2/doc/index.html?a=M000261&name=polymorphic_path Thanks, Srikanth
