Ruby on rails devise is not permitting all fields - ruby-on-rails

Question

In ruby on rails i use devise for authentication and add the first and last name fields to the database. The new view looks like
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div class="field">
<%= f.label :first_name %><br />
<%= f.text_field :first_name, autofocus: true %>
</div>
<div class="field">
<%= f.label :last_name %><br />
<%= f.text_field :last_name, autofocus: true %>
</div>
<div class="field">
<%= f.label :email %><br />
<%= f.email_field :email, autofocus: true %>
</div>
<div class="field">
<%= f.label :password %>
<% if #minimum_password_length %>
<em>(<%= #minimum_password_length %> characters minimum)</em>
<% end %><br />
<%= f.password_field :password, autocomplete: "off" %>
</div>
<div class="field">
<%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation, autocomplete: "off" %>
</div>
<div class="actions">
<%= f.submit "Sign up" %>
</div>
<% end %>
The controller looks like this
private
def sign_up_params
params.require(:user).permit(:email, :password, :password_confirmation,:first_name, :last_name)
end
def account_update_params
params.require(:user).permit(:first_name, :last_name, :email, :password, :password_confirmation, :current_password)
end
When creating the account I get a successful request but I am when I look at the database only the first name attribute show up and not the last name attribute. Form the sql queries generated only the first name attribute gets inserted into the sql statement.

Check Following Code, it will help you
class ApplicationController < ActionController::Base
before_action :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.permit(:sign_up) do |user_params|
user_params.permit({ roles: [] }, :email, :password, :password_confirmation)
end
end
end
And for extra help read Devise Strong Parameters topic.

Answer 2

There are a few things you could try:
First do a bang class permitting all variables to be entered in the form and see if last_name gets saved. by declaring .permit! and removing (:email, :password, :password_confirmation, etc...)
If last_name gets saved when banging that class - You should see if entering the correct classes in the form_for tag helps you.
<%= form_for(user, as: user, url: registration_path(user)) do |f| %>
If not, look in your db/schema file and see if you accidently migrated last_name as something other than a string.
