Question

我正在尝试以横向格式发送.pdf。我一直在使用WickedPdf.new.pdf_from_string方法来尝试这样做。即使我指定横向格式，电子邮件的PDF也是纵向的。

如果有人能告诉我实现这一目标的方法，我将非常感激。

邮件程序：

class ProjectMailer < ActionMailer::Base
  def email_mindmap_process(project, user, unused_list_items_column1, unused_list_items_column2)
    @project = project
    @user = user
    mail(:subject => "You've received a MindMap from #{@user.email}!", :to => @project.destination_email) do |format|
      format.pdf do
        attachments["#{@project.title}.pdf"] = WickedPdf.new.pdf_from_string(render_to_string(:pdf => "MindMap", :template => 'projects/show.pdf.html.erb', :orientation => 'Landscape', :locals => {:project => @project, :user => @user }))
      end
    end
  end
end

控制器：

def email_mindmap_process
  @project = Project.find(params[:id])
  @user = current_user
  begin
    ProjectMailer.email_mindmap_process(@project, @user, @unused_list_items_column1, @unused_list_items_column2).deliver
    flash[:notice] = "We have emailed your MindMap to #{@project.destination_email}"
  rescue Net::SMTPAuthenticationError, Net::SMTPServerBusy, Net::SMTPSyntaxError, Net::SMTPFatalError, Net::SMTPUnknownError => e
    flash[:error] = "There was a problem emailing #{@project.destination_email}. Please double-check the address"
  end
end

我联系了WickedPDF宝石的创建者Miles Sterrett，他推荐了以下内容，它完美无缺！

attachments["#{@project.title}.pdf"] = WickedPdf.new.pdf_from_string(render_to_string(:pdf => "MindMap", :template => 'projects/show.pdf.html.erb',  :locals => {:project => @project, :user => @user }), {:orientation => 'Landscape'})

非常感谢Miles迅速做出回应，并建立了这样一个有用的宝石！

Answer 2

我想分享一个我发现没有使用render_to_string的解决方案。我正在解析erb文件，然后将该字符串作为pdf_from_string中的第一个arg传递。

示例

parsed_content = File.read("#{Rails.root}/app/views/content.erb") render = ERB.new(parsed_content) content = render.result(binding) pdf = WickedPdf.new.pdf_from_string( content, :orientation => 'Landscape' )

我希望这对某人有帮助。
