Answer 1

I'm in similar shoes as you, after trying all sorts of approaches I went with a single User model, which would belong to polymorphic roles. This seems like the simplest way to achieve single-login.

The User model would contain the information specific to log-in only.

The Role model would store fields specific to each role, as well as other associations specific to the role.

New registrations would be customized for each user type (roles) via individual controllers, and then building nested attributes for the User.

class User < ActiveRecord::Base
    #... devise code ...
    belongs_to :role, :polymorphic => true
end

class Member < ActiveRecord::Base
    attr_accessible :name, :tel, :city  #etc etc....
    attr_accessible :user_attributes #this is needed for nested attributes assignment

    #model specific associations like  
    has_many :resumes

    has_one :user, :as => :role, dependent: :destroy
    accepts_nested_attributes_for :user
end 

Routes -- just regular stuff for the Member model.

resources :members
#maybe make a new path for New signups, but for now its new_member_path

Controller -- you have to build_user for nested attributes

#controllers/members_controller.rb
def new
    @member = Member.new
    @member.build_user
end

def create
    #... standard controller stuff
end

views/members/new.html.erb

Sign up for new members!
<%= simple_form_for @member do |f| %>

    # user fields
    <%= f.fields_for :user do |u| %>
      <%= u.input :email, :required => true, :autofocus => true %>
      <%= u.input :password, :required => true %>
      <%= u.input :password_confirmation, :required => true %>
    <% end %>

    # member fields
    <%= f.input :name %>
    <%= f.input :tel %>
    <%= f.input :city %>

    <%= f.button :submit, "Sign up" %>
<% end %>

I would like to point out that there is NO NEED to reach for nested_form gem; since the requirement is that User can only belong_to one type of Role.
