Sprockets Error : Sprockets::Rails::Helper::AssetNotFound

Question

我面临着链轮与倾斜宝石的奇怪错误.基本上，我加载图像的ERB模板（生成与倾斜）与图像标签，但当模板呈现时，它显示了 Sprockets::Rails::Helper:: AssetNotFound. The asset "button.jpg" is not present in the asset pipeline.. 我已经配置好了我的资产路径，下面我将附上文件。另一件事是，当我按下后退按钮并刷新页面时，图像会被加载适当的资产。我已经尝试了改变资产路径，以及尝试了 rake assets:precompile 但仍然保持不变。所有的资产都位于。app/assets/images

merge. rb

class Generator

            include ApplicationHelper
            include ActionView::Helpers::AssetTagHelper
            include Sprockets::Rails::Helper
            def initialize(template, scope = {})
              scope.each do |k, v|
                instance_variable_set k, v
              end

              f = "#{Rails.root}/app/views/#{template}.html.erb" if File.exist? "#{Rails.root}/app/views/#{template}.html.erb"


              if f
                @template = Tilt::ERBTemplate.new(f)
              else
                f = "#{Rails.root}/app/views/#{template}" if File.exist? "#{Rails.root}/app/views/#{template}"

                @template = Tilt.new(f)
              end
            end

            def request
              ActionDispatch::Request.new({})
            end

            def render
              @template.render(self) ===> Here is the render error
            end
         end

模板.erb

     <div class="facility-button">
       <center><%= link_to image_tag("button.jpg" , style: "max-width: 100%;height: auto;") , "#{@email.url}" %></center>
     </div>

开发.rb

Rails.application.config.assets.version = '1.0'


Rails.application.config.assets.precompile += %w[vendor.js]

开发.rb

  config.assets.compile = true
  config.assets.debug = true
  config.assets.quiet = true

如果有什么不清楚的地方，请写下注释。先谢谢你

通过添加这个，我的问题就解决了。

<center><%= link_to image_tag(ActionController::Base.helpers.asset_path("button.jpg") , style: "max-width: 100%;height: auto;") , "#{@email.url}" %></center>

如果有谁能详细说明为什么会这样，谢谢
