undefined method regular_user_path (oath object oriented approach) - ruby-on-rails

Question

I have implemented an oath object oriented approach to my rails application using this tutorial. I've also split my User Form into an Edit & Account Form.
User Edit Form
-Name
-Username
-AboutMe
User Account Form
-Email
-Password
-Password Confirmation
Everything seems to be working okay, until I try to Edit a Regular User's Account or Profile. For some reason I keep getting this error.
undefined method `regular_user_path' for #<#<Class:0x007fc1952f6da0>:0x007fc18bf350a8>
I am not sure why this may be happening. Here is my code below.
Models
class User < ActiveRecord::Base
attr_accessible :name, :bio, :avatar, :username
end
class RegularUser < User
has_secure_password
VALID_EMAIL_REGEX = /\A[\w+\-.]+#[a-z\d\-.]+\.[a-z]+\z/i
VALID_UNAME_REGEX = /^[a-z](\w*[a-z0-9])*$/i
validates :name, length: { maximum: 50 }
validates :username, :presence => true,
:length => { :maximum => 15 },
:format => { :with => VALID_UNAME_REGEX },
:uniqueness => { :case_sensitive => false }
validates :bio, length: { maximum: 50 }
end

end
end

Answer 1

In your update action do as suggested below :
def update
#user = RegularUser.find(current_user.id)
if #user.update_attributes(params[:user])
flash[:success] = "Profile updated"
sign_in #user
redirect_to root_url
else
error_messages = #user.errors.messages ### Capture the error messages
#user = User.find_by_username(params[:id]) ### Add this line
#user.errors.messages.merge!(error_messages) ### Set the error messages hash
if URI(request.referer).path == edit_user_path
render 'edit'
else
render 'account'
end
end
end
When your update fails, you need to reset #user to User instance otherwise when you render edit view it will receive RegularUser instance rather than User instance whereas your form is expecting User instance.

Try adding resources :regular_users to your routes.rb file
