Question

我正在尝试根据WickedPDF中要求的对象向文件添加自定义名称。此操作可以很好地用作控制器操作，但是一旦进入Sidekiq工作程序，它就不会说没有针对Issueable（多态）对象的方法name，该方法以字符串形式返回（这很可能是我所有问题在那里，但我不知道如何解决它。）

相关行：

save_path = Rails.root.join('public', "#{@issueable.name}_checklist.pdf")

Sidekiq控制台输出中上下文中的准确错误：

完整的generate_checklist_worker.rb：

class GenerateChecklistWorker
  include Sidekiq::Worker
  sidekiq_options retry: false

  def perform(issueable, issues, event_issues)
    @issueable = issueable

    av = ActionView::Base.new()
    av.view_paths = ActionController::Base.view_paths

    av.class_eval do
      include Rails.application.routes.url_helpers
      include ApplicationHelper
    end

    pdf = av.render template: 'issues/checklist.pdf.erb',
    locals: {:issueable => @issueable, :issues => @issues, :event_issues => @event_issues}

    pdf = WickedPdf.new.pdf_from_string(
      pdf,
      disposition:  'attachment',
      dpi:          '144',
      header:       {html: {template: 'layouts/_checklist_header'}, spacing: 5 },
      footer:       {html: {template: 'layouts/_checklist_footer'}, spacing: 0 },
      margin:       {top: 30, bottom: 20, left: 10, right: 10},
      locals:       {:issueable => @issueable},
      #cover:        ApplicationController.new.render_to_string('issues/checklist_cover.pdf.erb'), locals: {:issueable => issueable}
    )

    save_path = Rails.root.join('public', "#{@issueable.name}_checklist.pdf")
    File.open(save_path, 'wb') do |file|
      file << pdf
    end
  end
end

这是控制器中调用此方法的方法：

def checklist
    @issues = @issueable.issues.kept.non_event_issues.ordered_issues
    @event_issues = @issueable.issues.kept.event_issues.order(issue_number: :asc)
    GenerateChecklistWorker.perform_async(@issueable, @issues, @event_issues)
    redirect_to @issueable
end

Answer 1

您不能将复杂的Ruby对象序列化为Sidekiq参数。您需要在工作中查找事物（即，通过调用find）。

在Sidekiq任务中访问wicked_pdf的对象元素
