我跟随this tutorial但未能如何将用户重定向到页面以在与omniauth连接时填写更多信息。
在我的用户模型中，我有：
user = User.new(
name: auth.extra.raw_info.name,
user_name: auth.info.nickname,
about_me: auth.info.description,
email: email ? email : "#{TEMP_EMAIL_PREFIX}-#{auth.uid}-#{auth.provider}.com",
password: Devise.friendly_token[0,20]
)
user.skip_confirmation!
user.save!
在我的Omniauth回调控制器中，我有：
def after_sign_in_path_for(resource)
if resource.profile_valid?
super resource
else
finish_signup_path(resource
end
end
profile_valid检查：
def profile_valid?
self.email && self.email !~ TEMP_EMAIL_REGEX
end
Twitter auth没有给您发送电子邮件，我需要注册，所以我传递了一个带有正则表达式的虚拟电子邮件（TEMP_EMAIL_REGEX）。
因此，当有效的电子邮件不存在时，它应该重定向到包含以下内容的finish_signup_page：
<div id="add-email" class="container">
<h1>Add Email</h1>
<%= form_for(current_user, :as => 'user', :url => finish_signup_path(current_user), :html => { role: 'form'}) do |f| %>
<% if @show_errors && current_user.errors.any? %>
<div id="error_explanation">
<% current_user.errors.full_messages.each do |msg| %>
<%= msg %><br>
<% end %>
</div>
<% end %>
<!-- User Name -->
<div class="form-group">
<%= f.label :user_name %>
<div class="controls">
<%= f.text_field :user_name, :autofocus => true, :value => '', class: 'form-control', placeholder: 'Username' %>
<p class="help-block">Please enter your username</p>
</div>
</div>
<div class="form-group">
<%= f.label :email %>
<div class="controls">
<%= f.text_field :email, :autofocus => true, :value => '', class: 'form-control', placeholder: 'Example: email@me.com' %>
<p class="help-block">Please confirm your email address. No spam.</p>
</div>
</div>
<div class="actions">
<%= f.submit 'Continue', :class => 'btn btn-primary' %>
</div>
<% end %>
</div>
这是我的问题，当我输入一些它没有保存用户的东西时，如果在实际字段中存在当前值会更好吗？
但是我迷失了如何做到这一点，或者我现在尝试这个太长时间并且有一个隧道视野。
我想念的是什么？

首先浏览以下课程。您需要为用户存储正确的数据，生成的电子邮件不是一个好的解决方案。因此，我们基本上将提供商的数据存储在单独的模型中Social Provider。
- sp =创建社交提供商
- 用户通过从提供商处收到的数据进行初始化（未保存）。
- 我们将sp id存储在会话中，以将其与用户范围隔离开来。
- 我们渲染设备注册/新视图（添加我们需要的所有字段）。
- 成功注册后，我们将sp链接到创建的用户。
update_from_oauth方法，用于更新用户的主要属性而不保存。##########################
