I am doing Authentication app using Devise (as Engine). I followed the steps from https://github.com/p...ountable-engine every thing goes perfectly until i reach the command 

 

rails generate devise MODEL Actually I gave User instead of MODEL

 

from the above link after this command it shows some errors

I thought Database connection not established properly so i tested using the command

 

rails generate model Test name:string email:string

 

its working properly, then i gave

 

rake db:migrate

 

Now database also migrated successfully, so i think database connection is properly working. The commands mentioned above were run from Engine's Directory. If any information needed comment it out i will provide the details. Thanks
