PDF封面页停止PDF生成的其余部分

处理PDF和(在开发和生产中)PDF将只呈现封面:

https://www.patchvault.org/lodges/456a-powhatan/issues/checklist.pdf

调试显示了其他内容,没有封面:

https://www.patchvault.org/lodges/456a-powhatan/issues/checklist.pdf?debug=true

这会间歇性地渲染,或者显示后续页面没有图像(典型的渲染时间),但大部分只是渲染封面。 禁用控制器操作中的封面会使其他页面按预期呈现。 以下是控制器操作(我为了开发目的禁用了附件):

def checklist
    # PDF Checklist of issues from a lodge
    @issues = @issueable.issues.non_event_issues.ordered_issues
    @event_issues = @issueable.issues.event_issues.order(issue_number: :asc)
    respond_to do |format|
      format.html
      format.pdf do
        render pdf:   "#{@issueable.slug}_checklist",
        # disposition:  'attachment',
        template:     'issues/checklist.pdf.erb',
        cover:        render_to_string('issues/checklist_cover.pdf.erb'),
        dpi:          '150',
        background:   true,
        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},
        show_as_html: params.key?('debug')
      end
    end
  end

以下是开发到wkhtmltopdf的输出结果:

封面是一个完整的HTML页面,因为它不会呈现样式而不是一个并调用CSS文件。
