用户名未保存？或在用户个人资料上显示

Question

因此，我有一个应用程序允许用户在注册时选择用户名 - 但是，当他们登录时，用户名在注册时保存并显示在他们的个人资料中时是空白的。

这里的注册表单的快照：

<div class="home-page-m"> 
    <div class="container"> 
     <p class="banner-heading">Meet new people and make new friends</p> 
     <div class=" col-md-4 col-xs-12 sign-up-form"> 
     <div class="panel panel-default"> 
      <div class="panel-heading"> 
      <h3 class="panel-title">Sign Up</h3> 
      </div> 
      <div class="panel-body"> 
      <%= simple_form_for('user', :as => 'user', :url => registration_path('user')) do |f| %> 
      <form role="form"> 
       <div class="form-group"> 
       <label for="exampleInputEmail1"></label> 
       <%= f.text_field :username, class: 'form-control', id: 'Email1', placeholder: 'Username', required: true %> 
       </div> 
       <div class="form-group"> 
       <label for="exampleInputEmail1"></label> 
       <%= f.text_field :first_name, class: 'form-control', id: 'Email1', placeholder: 'First Name', required: true %> 
       </div> 
       <div class="form-group"> 
       <label for="exampleInputEmail1"></label> 
       <%= f.text_field :last_name, class: 'form-control', id: 'Email1', placeholder: 'Last Name', required: true %> 
       </div> 
       <div class="form-group"> 
       <label for="exampleInputEmail1"></label> 
       <%= f.email_field :email, class: 'form-control', id: 'Email1', placeholder: 'Email', required: true %> 
       </div> 
       <div class="form-group"> 
       <label for="exampleInputPassword1"></label> 
       <%= f.password_field :password, class: 'form-control', id: 'Password', placeholder: 'Password', required: true %> 
       </div> 
       <div class="form-group"> 
       <label for="exampleInputEmail1"></label> 
       <%= f.text_field :zip, class: 'form-control', id: 'zip', placeholder: 'Zip', required: true %> 
       </div> 
       <div class="form-group"> 
       <label for="Date" style="display:block; margin-bottom:5px; text-decoration: underline;">Date of Birth :</label> 
       <div class="row birth-date"> 
       <%= f.date_select :birthday, { 
        :order => [:month, :day, :year], 
        :start_year => 1950, 
        :end_year => 2004} %> 
       </div> 
       <div class="clr"></div> 
      </div> 
       <div class="col-md-12 text-center sign-b"> 
       <%= f.submit 'Create Account', class: 'btn btn-default creat-event' %> 
       <p>By clicking the button you agree to<br> 
        the terms and conditions</p> 
       </div> 
       </form> 
       <% end %> 
      </div> 
      </div> 
     </div> 
     </div> 
    </div> 

这里的地方的用户名应在用户显示注册后的程序：

<div class="users_about_fullinfo"> 
      <h3><%= current_user.name %> <small>(<%= current_user.username %>)</small></h3> 
      <p class="edit-about-text"> 
       <%= best_in_place current_user, :blurb, activator: ".edit-blurb", nil: 'Click here to add a short blurb (maximum 140 characters)', inner_class: 'form-control', ok_button: 'Save', ok_button_class: 'btn btn-default btn-xs creat-event blurb-ok', cancel_button: 'Cancel', cancel_button_class: 'btn btn-default btn-xs cencel-event blurb-cancel' %> 
       <span class="edit-icon edit-blurb"></span> 
      </p> 
      </div> 
      <div class="clr"></div> 

为什么不显示用户名在上面？不要忘记，current_user.name显示，但不是用户名..

任何帮助将是真棒，欢呼！

更新：与用户控制器

class UsersController < ApplicationController 
    before_filter :authenticate_user! 

    def index 
    @users = User.all 
    end 

    def edit 
    @user = User.find(params[:id]) 
    end 

    def update 
    @user = User.find(params[:id]) 

    respond_to do |format| 
     if @user.update(params[:user]) 
     format.html { redirect_to profile_path} 
     format.json { respond_with_bip(@user) } 
     format.js 
     else 
     format.html { render edit} 
     format.json { respond_with_bip(@user) } 
     format.js 
     end 
    end 
    end 

    def show 
    @user = User.find(params[:id]) || current_user 
    @questions_for_about = @user.questions.for_about.order('id asc') 
    @questions_for_personality = @user.questions.for_personality.order('id asc') 
    end 

    def edit_profile 
    @user = current_user 
    @questions_for_about = @user.questions.for_about.order('id asc') 
    @questions_for_personality = @user.questions.for_personality.order('id asc') 
    end

    current_user.update_attributes(birthday: params[:user][:birthday]) 
    end 

    def refresh_notifcations 
    @new_messages = current_user.new_messages.count 
    end 

    # disconnect from social networks 
    def disconnect 
    social = params[:social] 
    current_user.disconnect(social) 
    redirect_to :back 
    end 

    def visitors 
    @visitors = current_user.recent_visitors.order('visited_at desc') 
    end 

    def toggle_hidden 
    @hidden_user_id = params[:hidden_user_id] # sent to js.erb 
    if params[:action_type] == 'hide' 
     current_user.hidden_users.find_or_create_by(hidden_user_id: @hidden_user_id)

     current_user.blocked_users.find_or_create_by(blocked_user_id: @blocked_user_id) 
    end 
    end 

    def account_registration 
    @hidden_users = User.where(id: current_user.hidden_users.pluck(:hidden_user_id)) 
    @blocked_users = User.where(id: current_user.blocked_users.pluck(:blocked_user_id)) 
    @events = current_user.events 
    @activities = current_user.activities 
    end 

    def update_profile_completness 
    respond_to do |format| 
     format.js 
    end 
    end 

    def disable_account 
    current_user.disable_account 
    Devise.sign_out_all_scopes ? sign_out : sign_out(current_user) 
    redirect_to root_path, notice: 'Account was disabled. Sign in to enable it again.' 
    end 

private 
    # Using a private method to encapsulate the permissible parameters 
    # is just a good pattern since you'll be able to reuse the same 
    # permit list between create and update. Also, you can specialize 
    # this method with per-user checking of permissible attributes.

尝试添加以下内容到Application Controller。检查设计文档以获得最适合您的应用的实现。如果用户被允许从他们的账户设置更改他/她的用户名，您可能需要用户创建和用户更新。

https://github.com/plataformatec/devise#strong-parameters

class ApplicationController < ActionController::Base 
    protect_from_forgery with: :exception 
    before_action :configure_permitted_parameters, if: :devise_controller? 

    protected 

    def configure_permitted_parameters 
    devise_parameter_sanitizer.for(:sign_up) << [:username] 
    end 
end
