ruby-on-rails - Rails 3.2 Carrierwave 预编译错误

Question

我有一个 class AvatarUploader < Carrierwave::Uploader::Base哪家店User public/uploads 中的头像目录:

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  version :main do
     process :resize_to_limit => [128, 128]
  end

我想在production开始申请启用 Assets 预编译的模式。除了头像以外的一切都可以正常工作。当我访问任何 User我得到的个人资料:

Started GET "/users/1" for 127.0.0.1 at 2012-05-03 17:45:24 +0300
Processing by Users::UsersController#show as HTML
  Parameters: {"id"=>"1"}
  Rendered users/users/show.html.erb within layouts/application (2.5ms)
Completed 500 Internal Server Error in 16ms

ActionView::Template::Error ( isn't precompiled):
    87:                     <%= image_tag @user.avatar_url(:main).to_s %>
  app/views/users/users/show.html.erb:87:in `_app_views_users_users_show_html_erb___538221278131396366_28399560'

也许有一种方法可以关闭头像的预编译(因为当应用程序在生产环境中运行时可以重新上传)。请提供有关如何解决此问题的任何建议。谢谢。

Answer 1

When image_tag receives a blank string, it tries to get a resource from the asset pipeline and returns

"isn't precompiled"

打印 @user.avatar_url(:main).to_s 来仔细检查
