我正在使用imgkit拍摄我的网页快照.我跑:
RAILS_ENV =生产包exec rake资产:预编译预编译我的资产.
app / assets目录的所有文件都编译为public / assets
application.css编译为application-7a23a105125768e41d9d24aee4553615.css.
我的控制器代码是:
kit = IMGKit.new(render_to_string(:partial => 'form',:height => 200,:transparent => true,:quality => 10,:layout => false,:locals => {:project => @project})) # t = kit.to_img(:png) kit.stylesheets << "#{Rails.root.to_s}/public/assets/application.css" #file = kit.to_file(Rails.root + "public/pngs/" + "screenshot.png") file = kit.to_file(Rails.root + "public/assets/" + "screenshot.png") #send_file("#{Rails.root.to_s}/public/pngs/screenshot.png",:filename => "screenshot.png",:type => "image/png",:disposition => 'attachment',:streaming=> 'true')
我不知道如何解决/public/assets/application.css未找到错误…
没有这样的文件或目录 – public / assets / application.css
我使用https://github.com/csquared/IMGKit/issues/36来获取CSS并在我的快照中工作
编辑
def update #@kit = IMGKit.new(render_to_string,width: 480,height: 800,:quality => 100) respond_to do |format| if @project.update(project_params) kit = IMGKit.new(render_to_string(:partial => 'form',:locals => {:project => @project})) # t = kit.to_img(:png) kit.stylesheets << "self.class.helpers.asset_path('application.css')" #file = kit.to_file(Rails.root + "public/pngs/" + "screenshot.png") file = kit.to_file(Rails.root + "public/assets/" + "screenshot.png") #send_file("#{Rails.root.to_s}/public/pngs/screenshot.png",:streaming=> 'true') format.html { redirect_to root_path,notice: 'Flyer was successfully updated.' } format.json { render :show,status: :ok,locatioFlyern: @project } else format.html { render :edit } format.json { render json: @project.errors,status: :unprocessable_entity } end end end
解决方法
您可以使用Sprockets :: Rails :: Helper#asset_digest_path,找到
here.由于您在控制器中,因此您可以访问它
self.class.helpers.asset_digest_path('application.css') # => "application-7a23a105125768e41d9d24aee4553615.css"
同样,asset_path将生成application.css文件的路径
self.class.helpers.asset_path('application.css') # => "/assets/application-7a23a105125768e41d9d24aee4553615.css"
