undefined method `email' for #<UserInfo:0xc0ac77c> - ruby-on-rails

Question

I have this problem in rails..
It says undefined method email for #<UserInfo:0xc0ac77c>
I debug this several times i could not trace the error.
here is the sample code i have.
user_infos_controller.erb
class UserInfosController < ApplicationController
before_action :check_user_profile, only: :index
def index
#user = User.find(current_user.id)
puts #user
end
def new
#user_info = current_user.build_user_info
end
def show
#user = User.find(current_user)
end
def create
#user_info = UserInfo.create(
user_id: current_user.id,
fname: params[:user_info][:fname],
lname: params[:user_info][:lname],
bday: params[:user_info][:bday],
address: params[:user_info][:address],
picture: params[:user_info][:picture])
#if #user_info.save
#redirect_to user_infos
#else
#render new_user_info_path
#end
end
private
def profile_params
params.require(:user_info).permit(:fname, :lname, :bday, :address, :picture)
end
private
def check_user_profile
user = User.find(current_user)
if !user.user_info
redirect_to new_user_info_path
end
end
end
new.html.erb
<%= simple_form_for #user_info, html: { multipart: true } do |f| %>
<% if #user_info.errors.any? %>
<h2><%= pluralize(#user_info.errors.count, "error") %> Prevented this User from saving </h2>
<ul>
<% #user_info.errors.full_messages.each do |mg| %>
<li><%= msg %></li>
<% end %>
</ul>
<% end %>
<div class="form-group">
<%= f.input :picture, input_html: { class: "form-control"} %>
</div>
<div class="form-group">
<%= f.input :fname, input_html: { class: "form-control"} %>
</div>
<div class="form-group">
<%= f.input :lname, input_html: { class: "form-control"} %>
</div>
<div class="form-group">
<%= f.input :address, input_html: { class: "form-control"} %>
</div>
<div class="form-group">
<%= f.date_field :bday, input_html: { class: "form-control"} %>
</div>
<div class="form-group">
<button class="btn btn-primary pull-right" type="submit">Save</button>
</div>
<% end %>
This is for the user database
class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|
## Database authenticatable
t.string :email, null: false, default: ""
t.string :encrypted_password, null: false, default: ""
## Recoverable
t.string :reset_password_token
t.datetime :reset_password_sent_at
## Rememberable
t.datetime :remember_created_at
## Trackable
t.integer :sign_in_count, default: 0, null: false
t.datetime :current_sign_in_at
t.datetime :last_sign_in_at
t.string :current_sign_in_ip
t.string :last_sign_in_ip
## Confirmable
# t.string :confirmation_token
# t.datetime :confirmed_at
# t.datetime :confirmation_sent_at
# t.string :unconfirmed_email # Only if using reconfirmable
## Lockable
# t.integer :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts
# t.string :unlock_token # Only if unlock strategy is :email or :both
# t.datetime :locked_at
t.timestamps null: false
end
add_index :users, :email, unique: true
add_index :users, :reset_password_token, unique: true
# add_index :users, :confirmation_token, unique: true
# add_index :users, :unlock_token, unique: true
end
end
And this is for user_infos database
class CreateUserInfos < ActiveRecord::Migration
def change
create_table :user_infos do |t|
t.string :fname
t.string :lname
t.date :bday
t.string :address
t.timestamps null: false
end
end
end
class AddAttachmentPictureToUserInfos < ActiveRecord::Migration
def self.up
change_table :user_infos do |t|
t.attachment :picture
end
end
def self.down
remove_attachment :user_infos, :picture
end
end

Answer 1

Devise method in your models accepts some options to configure its modules.
So if you use devise on User model then you have to remove Devise methods from UserInfo model which is below
Remove this from UserInfo
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
For configuring Devise for multiple models have look at following documentation link
https://github.com/plataformatec/devise
Hopefully this will help.

Answer 2

I don't see any reason for getting NoMethodError (undefined method 'email' for #<UserInfo:0xbcaa624>) error, but 1 issue I can see is :
In create method of UserInfosController you have written :
#user_info = UserInfo.create(
user_id: current_user.id,
fname: params[:user_info][:fname],
lname: params[:user_info][:lname],
bday: params[:user_info][:bday],
address: params[:user_info][:address],
picture: params[:user_info][:picture])
but in user_infos table you haven't added the column for user_id. You should add the column user_id to user_infos table through migration like this :
class AddUserIdToUserInfos < ActiveRecord::Migration
def self.up
change_table :user_infos do |t|
t.references :user, foreign_key: true, index:true
end
end
def self.down
t.remove_references(:user)
end
end
