Role is not being added to users in database - ruby-on-rails

Question

I've been having issues creating separate users for my rails web application. Today I tried to follow Zhurora's answer to a similar post. https://stackoverflow.com/a/32159123
However now when users are signing up on the signup page, and select a role from the options, that role does not get written into the database. I had set up the migrations as instructed and when I check the schema it has an entry for role.
However it still doesnt get added. This is what happens in the terminal when a user signs up after selecting a role.
Started POST "/users" for 127.0.0.1 at 2018-04-07 19:54:54 +0200

And here is my user.rb model
class User < ApplicationRecord
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
enum role: {person: 0, restaurant: 1, admin: 2}
has_many :posts, dependent: :destroy
validates :role, presence: true
validates :name, presence: true, length: { minimum: 4 }
validates :password, presence: true, length: { minimum: 5 }
validates :password_confirmation, presence: true, length: { minimum: 5 }
end
My schema.rb file with the user table
create_table "users", force: :cascade do |t|
t.string "name", default: "", null: false
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.inet "current_sign_in_ip"
t.inet "last_sign_in_ip"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "role"
t.index ["email"], name: "index_users_on_email", unique: true
t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
end
The migration file
class AddRoleToUsers < ActiveRecord::Migration[5.1]
def change
add_column :users, :role, :integer
end
end
And my signup html.erb page
<%= bootstrap_form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
<%= f.text_field :name,
placeholder: 'username (will be shown publicly)',
class: 'form-control' %>
<%= f.text_field :email,
placeholder: 'email',
class: 'form-control' %>
<%= f.password_field :password,
placeholder: 'password',
class: 'form-control' %>
<%= f.password_field :password_confirmation,
placeholder: 'password confirmation',
class: 'form-control' %>
<%= f.select :role, collection: User.roles.keys.to_a %>
<%= f.submit 'Sign up', class: 'btn sign-up-button' %>
<% end %>
In my attempt to fix it, I have dropped all the tables, thinking it wasnt getting updated in postgresql properly.
Recreated the tables and run the migrations through again.
I have also deleted the schema file and ran the migrations again generating a new schema file.
None of that has worked.
Any help would be appreciated. Thank you very much

Answer 1

you need to permit additional parameters
class ApplicationController < ActionController::Base
before_action :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.permit(:sign_up, keys: [:role])
end
end

Answer 2

Thanks to Mezbah I looked into adding role to the permitted parameters.
I was blinded and overlooked that.
I overrided the registrations controller with my own
class RegistrationsController < Devise::RegistrationsController
private
def sign_up_params
params.require(:user).permit( :name,
:email,
:password,
:password_confirmation)
end
def account_update_params
params.require(:user).permit( :name,
:email,
:password,
:password_confirmation,
:current_password)
end
end
This is how it looked before.
And based on what Mezbah said, I added it to here
class RegistrationsController < Devise::RegistrationsController
private
def sign_up_params
params.require(:user).permit( :name,
:email,
:password,
:password_confirmation,
:role)
end
def account_update_params
params.require(:user).permit( :name,
:email,
:password,
:password_confirmation,
:current_password)
end
end
And now it works :D
Here is a successful entry into the database
