Answer 1

I used your code and it worked for me!

Here is what I did

class RegistrationsController < Devise::RegistrationsController
  skip_before_filter :verify_authenticity_token, :only => :create #, :if => Proc.new { |c| c.request.format == 'application/json' }
  respond_to :json, :html, :xml

  def create
    user = User.new(devise_registrations_permitted_parameters)
    if user.save
      render :json=> user.as_json(:auth_token=>user.authentication_token, :email=>user.email,:name => user.name), :status=>201
      return
    else
      warden.custom_failure!
      render :json=> user.errors, :status=>422
    end
  end


  protected                                                            
    def devise_registrations_permitted_parameters
      params.require(:user).permit(:name, :email, :password, :password_confirmation)
    end

end
