Adding roles to users in rails app? - ruby-on-rails

Question

So summary: I wanted to have two types of users which are teachers and students. They are all users and therefore inherit from the users controller. The problem is no about the controllers or classes existing, it's how to adapt them through a form and whether or not I'm missing anything. I'm not sure how to do a backend to radio buttons and have tried things from previous answers but they result in errors. Also, how do I change routes based on which role they select? I have a registrations controller to override Devise.
Here is my form:
<div class="authform"> <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :role => 'form'}) do |f| %>
<h2>Sign Up</h2>
<%= devise_error_messages! %>
<div class="form-group">
<%= f.label :name %>
<%= f.text_field :name, :autofocus => true, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :email %>
<%= f.email_field :email, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :password %>
<%= f.password_field :password, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :password_confirmation %>
<%= f.password_field :password_confirmation, class: 'form-control' %>
</div>
<div>
<%= f.radio_button :role, 'student' %>
<%= label :role_student, 'Student' %>
<%= f.radio_button :role, 'teacher' %>
<%= label :role_teacher, 'Teacher' %>
</div>
<%= f.submit 'Sign Up', :class => 'button right' %>
<% end %> </div>
I have a migration to add roles to users right here
class AddRoleToUsers < ActiveRecord::Migration
def change
add_column :users, :role, :integer
end
end
This was my original attempt on changing routes when adding roles (from another stack overflow question)
class RegistrationsController < Devise::RegistrationsController
def after_sign_up_path_for(resource)
if params[:user][:role] == 'student'
path_to_route = '/classrooms/index'
elsif [:user][:role] == 'teacher'
path_to_route = '/classrooms/new'
else
path_to_route = '/'
end
redirect_to path_to_route
end
end
Finally, here is my user's controller
class UsersController < ApplicationController
# before_action :authenticate_user!
before_action :logged_in_user, only: [:edit, :update]
before_action :correct_user, only: [:edit, :update]
after_action :verify_authorized
# before_filter :check_role
def show
#user = User.find(params[:id])
authorize #user
#posts = #user.posts
end
def new
#user = User.new
authorize #user
end
#def after_sign_up_path_for(resource)
# if params[:user][:role] == 'student'
# path_to_route = '/classrooms/index'
# elsif [:user][:role] == 'teacher'
# path_to_route = '/classrooms/new'
# else
# path_to_route = '/'
# end
# redirect_to path_to_route
#end
def update
#user = User.find(params[:id])
authorize #user
if #user.update_attributes(secure_params)
redirect_to users_path, :notice => "User updated."
else
redirect_to users_path, :alert => "Unable to update user."
end
end
def destroy
user = User.find(params[:id])
# authorize #user
user.destroy
redirect_to users_path, :notice => "User deleted."
end
def create_user_type
end
private
def secure_params
params.require(:user).permit(:role)
end
def logged_in_user
unless logged_in?
flash[:danger] = "Please log in."
redirect_to login_url
end
end
def correct_user
#user = User.find(params[:id])
redirect_to(root_url) unless #user == current_user
end
end
I know this is a bit of a long post, but I'd appreciate any help. Thanks so much! I love the rails community.

If you use simple_form you can use a standard input and assign the options to collection.
with simple_form
<%= f.input :role, collection: [:admin, :subscriber, :poster] %>
without simple_form
<%= f.select(:role, User.roles.keys.map {|role| [role.titleize,role]}) %>
user.rb
enum role: [:admin, :subscriber, :poster]
