设计，让注册控制器接受图像？

如何解决设计，让注册控制器接受图像？

| 我更新了views / devise / registrations / edit.html.erb以支持用户的回形针照片（User.photo）：

<%= form_for(resource,:as => resource_name,:url => registration_path(resource_name),:html => { :method => :put,:multipart => true }) do |f| %>

<p><%= f.label :photo %><br />
<%= f.file_field :photo %></p>

这似乎很好：

但是由于某种原因它不是保存到数据库吗？ 任何想法为什么会这样？     

解决方法

        我记得设计限制了蝙蝠可以访问的属性。 如果添加

attr_accessible :photo

对您的用户模型有效吗？     ,        我遇到了同样的问题。我想你应该确保你

ApplicationController

  before_filter :configure_permitted_parameters,if:  :devise_controller?

并定义方法 def configure_permitted_pa​​rameters     devise_parameter_sanitizer.for（：sign_up）{| u | u.permit（：photo，... here）}   结束
