Common Login for multiple Devise Login Modules in Rails 4

Question

In my app I have different types of users/models which is configured via devise gem for registration process. Let me make you more clear.

• For Doctor's Login I have this path http://localhost:3000/doctor/sign_in
• For Hospital's Login I have this path http://localhost:3000/hospital/sign_in
• For User's Login I have this path http://localhost:3000/user/sign_in

As all these have their own database tables like doctors , hospitals , users in which all details are saved respectively.

Now what I want to know that Is that possible to have Single Login page and I login with registered doctor's id then it should redirect me to Doctors page, If I login with hospital's id then it should redirect me to hospitals page, so on.. Is that possible to achieve this? If yes then Can you please guide me in right direction what should I need to do?

Note: I am aware about managing roles/user_types but I can not do that as there are different informations needed for doctors, hospitals and Users..

Answer 1

You can use Single Table Inheritance

class AuthUser < ActiveRecord::Base; end
class Doctor < AuthUser; end
class Hospital < AuthUser; end
class User < AuthUser; end

and use devise for AuthUser.

About after sign in path you can custom after_sign_in_path_for . Sample

Answer 2

What I think that there should be only one for saving users, ie, users . You can create a table named user_types which will contain user type names, ie, doctor, hospital and user. User belongs to a User Type. It would look something like this

class User
  belongs_to :user_type
end

class UserType
  has_many :users
end

Then in application controller you can override devise's after_sign_in_path_for method and redirect user to the page based on their user type.

Hope this makes sense!

or

If this is not possible then you can add three radio buttons for Doctor, User and Hospital, user will have to select it's login type along with the credentials before signing. Handle the login in the back end based on the value of the selected radio button.
