Mein Gerät Benutzermodell benutzerdefiniertes Feld Benutzername immer nil. Ich habe alle anderen Lösungen auf Stack-Überlauf versucht

Question

Meine Anwendung Controller Datei

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.permit(:sign_up) {|u| u.permit(:username, :email, :password, :password_confirmation, :remember_me)} 
    devise_parameter_sanitizer.permit(:sign_in) {|u| u.permit(:username, :email, :password, :password_confirmation, :remember_me)} 
    devise_parameter_sanitizer.permit(:account_update) {|u| u.permit(:email, :password, :password_confirmation, :remember_me)} 
    end 
end 

Meine routes.rb Datei

Rails.application.routes.draw do 
    devise_for :users 

    root 'pages#index' 

    get 'home' => 'pages#home' 

    get 'profile' => 'pages#profile' 

    get 'explore' => 'pages#explore' 


end

    def change 
    create_table :users do |t| 
     ## Database authenticatable 
     t.string :email,    null: false, default: ""

     ## 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 :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 

Mein Name einfügen Spalte Migration

class AddUsernameToUsers < ActiveRecord::Migration 
    def change 
    add_column :users, :username, :string 
    add_index :users, :username, unique: true 
    end 
end 

Meine Ansichten/ersinnen/Anmeldungen/new.html.erb

<%= bootstrap_devise_error_messages! %> 
<div class="panel panel-default devise-bs"> 
    <div class="panel-heading"> 
    <h4><%= t('.sign_up', default: 'Sign up') %></h4> 
    </div> 
    <div class="panel-body"> 
    <%= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { role: 'form' }) do |f| %> 
     <div class="form-group"> 
     <%= f.label :username %> 
     <%= f.text_field :email, autofocus: true, class: 'form-control' %> 
     </div> 
     <div class="form-group"> 
     <%= f.label :email %> 
     <%= f.email_field :email, class: 'form-control' %> 
     </div> 
     <div class="form-group"> 
     <%= f.label :password %> 
     <%= f.password_field :password, class: 'form-control' %> 
     </div> 
     <div class="form-group"> 
     <%= f.label :password_confirmation %> 
     <%= f.password_field :password_confirmation, class: 'form-control' %> 
     </div> 
     <%= f.submit t('.sign_up', default: 'Sign up'), class: 'btn btn-primary' %> 
    <% end %> 
    </div> 
</div> 
<%= render 'devise/shared/links' %> 

So auch nach dem starken Parameter verwenden, wenn die Benutzernamen durch Browser hinzugefügt werden, nicht zurück in die Datenbank übernommen.

Es gibt dieses Ergebnis

irb(main):001:0> u = User.all 
    User Load (20.0ms) SELECT "users".* FROM "users" 
=> #<ActiveRecord::Relation [#<User id: 1, email: "testuser@test.com", created_at: "2017-07-05 19:42:19", updated_at: "2017-07-05 21:11:38", username: nil>, #<User id: 2, email: "ajha@test.com", created_at: "2017-07-06 08:45:18", updated_at: "2017-07-06 08:45:18", username: nil>, #<User id: 3, email: "akasd@test.com", created_at: "2017-07-06 08:56:15", updated_at: "2017-07-06 08:56:15", username: nil>, #<User id: 4, email: "rcontest@test.com", created_at: "2017-07-06 09:23:55", updated_at: "2017-07-06 09:23:55", username: nil>]> 

Jede Hilfe geschätzt wird. Sagen Sie mir auch, wenn Sie andere Dateien sehen müssen.

Answer 1

Mein devise User-Modell benutzerdefinierte Feld Benutzername immer nil

Weil Sie es nicht haben in der Form. Ändern

<div class="form-group"> 
    <%= f.label :username %> 
    <%= f.text_field :email, autofocus: true, class: 'form-control' %> 
</div> 

dieser

<div class="form-group"> 
    <%= f.label :username %> 
    <%= f.text_field :username, autofocus: true, class: 'form-control' %> 
</div> 

Answer 2

Sie nicht username-Attribut in Form angegeben haben

hinzufügen Benutzernamen in Form

<div class="form-group"> 
    <%= f.label :username %> 
    <%= f.text_field :username, autofocus: true, class: 'form-control' %> 
    </div> 
    <div class="form-group"> 
    <%= f.label :email %> 
    <%= f.email_field :email, class: 'form-control' %> 
    </div>
