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，当他们登录用户名时，如果应该在注册时保存并显示在他们的个人资料中，则为空白。
以下是注册表单的快照：
<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>
此处注册后，用户个人资料中应显示用户名：
<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>
为什么没有显示那里的用户名？请记住，current_user.name正在显示但不是用户名..
任何帮助都会很棒，欢呼！
更新：使用用户控制器
class UsersController < ApplicationController
before_filter :authenticate_user!

@users = User.all
end

@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

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

@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)
elsif params[:action_type] == 'unhide'
current_user.hidden_users.where('hidden_user_id = ?', @hidden_user_id).first.destroy
end
end
def toggle_blocked
@blocked_user_id = params[:blocked_user_id] # sent to js.erb
if params[:action_type] == 'unblock'
current_user.blocked_users.where('blocked_user_id = ?', @blocked_user_id).first.destroy
elsif params[:action_type] == 'block'
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))

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.

尝试将此添加到Application Controller。检查设计文档以获取应用程序的最佳实现。如果允许用户从其帐户设置更改其用户名，则可能需要同时为用户创建和用户更新。
