Config setting

I currently want to do a login using a program. In addition to email and password, I want to have a username. I created a migration:

class AddUsernameToBuyer < ActiveRecord::Migration
  def change
    add_column :buyers, :username, :string
    add_index :buyers, :username, unique: true
  end
end

I also added the username in the registration view:

<h2>Sign up</h2>

<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>

  <div class="field">
   <%= f.label :username %> <br />
   <%= f.text_field :username %>
  </div>

  <div class="field">
    <%= f.label :email %><br />
    <%= f.email_field :email, autofocus: true %>
  </div>

  <div class="field">
    <%= f.label :password %>
    <% if @validatable %>
    <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 %>

<%= render "devise/shared/links" %>

And I entered the app controller username as an allowed parameter:

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
  before_action :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username) }
    end

    def after_sign_up_path_for(resource)
      redirect_to root_path
    end
end

When I try to register, I redirect as I should: http://localhost:3000/buyers/sign_up

After I filled out the details, I clicked the register button and I want to be redirected to the root page. However, devise redirects me to http://localhost:3000/buyers

and it tells me that I cannot have a blank username even though I added it.

How can I change this behavior / fix it?

To redirect you need to put after_sign_up_path_for

in RegistrationsController

. Create it first to override your own controller Devise

.



class RegistrationsController < Devise::RegistrationsController
  protected

  def after_sign_up_path_for(resource)
    root_path
  end
end

You need to generate a url in after_sign_in_path_for(resource)

. Try entering the code below.



def after_sign_in_path_for(resource)
  root_path
end
