NoMethodError in Devise. Undefined method `date_of_birth'

I am trying to add date_of_birth to my Devise form however, I keep getting an error message stating that the 'date_of_birth' is undefined method. See my code below. Any help will be greatly appreciated. I have been working on this all morning.

Devise/Registration/Edit

<div class="form-group"> <%= f.label :date_of_birth %> <%= f.date_select :date_of_birth, class: "form-control", :autofocus => true %> </div>

Assets/Application_Controller

class ApplicationController < ActionController::Base protect_from_forgery with: :null_session before_filter :configure_permitted_parameters, if: :devise_controller?

protected

 def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:name, :email, :password) }
    devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:name, :email, :password, :current_password, :gender, :date_of_birth, :avatar, :bio) }

end

Migration

class AddGenderToUsers < ActiveRecord::Migration def change add_column :users, :is_female, :boolean, default: false add_column :users, :date_of_birth, :datetime end end

My guess: you are allowing :date_of_birth only on edit (update), which means that when you are actually creating an account (sign_up), the birth date is set to null. You can check this in rails console by finding that user and checking whether he or she has a birthdate set. So if :date_of_birth is nil, when you go to the edit form, it can't fetch the :date_of_birth of that user and put it in the form.

Please add :date_of_birth to the :sign_up sanitizer, just like you did in the :account_update sanitizer in the configure_permitted_parameters method. Then wipe out all users from the database, create a new one and try editing the account again. It should display properly now.
