Start a production Rails console:
cd /opt/my/path/to/redmine bundle exec rails c production
In the console:
u=User.new(login: 'newadmin', admin: true, mail: '[email protected]', firstname:'Redmine' , lastname:'Admin') #password cannot be mass assigned so it needs to be specified separately u.password='newpassword' u.save => true #true means the creation was successful
In case save failed:
u.errors.messages #Displays saving errors
