本地开发图像路径不适用于 Rails 和 STI 上的 Carrierwave

Question

我正在尝试使用 CarrierWave 在本地上传（用于开发）。我的文件上传并保存到

 /public/uploads/news_page/hero_img/#{model.id}

但是，当我尝试在视图中调用此图像时，我得到了这条路径：

No route matches [GET] "/uploads/news_page/hero_img/13/7388aa89cc3aef55b4de707420fcd1d7.jpeg"

但那是图像所在的位置，它以该名称存储在数据库中（只是图像名称）。我不知道为什么它在视图中显示损坏的图像。

view.rb

figure
  = image_tag @page.hero_img, alt: 'hero'

hero_img_uploader.rb

class HeroImgUploader < CarrierWave::Uploader::Base

 include CarrierWave::RMagick
 CarrierWave::SanitizedFile.sanitize_regexp = /[^[:word:]\.\-\+]/
 # storage :fog
 include CarrierWave::MimeTypes
 process :set_content_type

  storage :file unless Rails.env == "production"
  # storage :fog unless Rails.env == "development"
  # storage :fog unless Rails.env == "test"
  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

 # def store_dir
 #  "pages/#{model.id}/hero/"
 # end

# Process files as they are uploaded:
  process :resize_to_limit => [1500, 500]

  version :md do
    process :resize_to_limit => [900, 300]
  end

  version :sm do
    process :resize_to_limit => [420, 140]
  end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_white_list
    %w(jpg jpeg gif png)
  end

  def filename 
    if original_filename 
      @name ||= Digest::MD5.hexdigest(File.dirname(current_path))
      "#{@name}.#{file.extension}"
    end
  end

end

development.rb

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.


  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  config.serve_static_files = false
  config.assets.compile = true
  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  config.action_mailer.raise_delivery_errors = false

  config.active_support.deprecation = :log

  config.active_record.migration_error = :page_load

  # Debug mode disables concatenation and preprocessing of assets.

  config.assets.debug = true

  config.assets.digest = true

  config.assets.raise_runtime_errors = true

  # Configurations for MailCatcher
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = { :address => "localhost", :port => 1025 }

  config.action_mailer.default_url_options = { host: 'localhost', port: 5000 }

  CarrierWave.configure do |config|
    config.storage = :file
  end


end

案件结案！只需更改此行：

config.serve_static_files = false

给这个：

config.serve_static_files = true

在您的 config/development.rb 文件中。

可能您之前无意中进行了更改（在 production 环境中这是有道理的，因为您有另一台服务器来提供资产，例如 nginx 或 Apache）。
