Problem while creating new resource on ActiveAdmin

HI All,

I have installed the Active Admin successfully, but facing the following
error while restarting the server after generating an resource.

     *rails generate active_admin:resource item*

Did you remember to run migrate on the database?

Re: Problem while creating new resource on ActiveAdmin

Yeah I was able to execute rake db:migrate before creating the new
resource, but after creating the resource it throws the  same error. Please
have a look on the below , do i need to create controller or model for Item
to get it run?

/Desktop/training/RAILS/courier$ rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
uninitialized constant Item
