安装程序：Rails 4.1.1应用程序使用 gem 'wicked_pdf', '~> 0.11.0' 和手动安装的wkhtmltopdf二进制版本0.12.1（带有修补的qt）

我有两个控制器生成类似的pdf报告，共享几页 . 我对两种报告类型之间共享的页面有部分内容 .

控制器代码：

# GET /assessments/1
def show
  respond_to do |format|
    format.html
    format.pdf do
      render pdf:          "Individual_Report-#{Date.today}",
             disposition:  "inline",
             layout:       "pdf",
             dpi:          "300",
             encoding:     "UTF-8",
             show_as_html: params[:debug].present?
    end
  end
end

# GET /reports/1
def show
  respond_to do |format|
    format.html
    format.pdf do
      render pdf:          "Team_Report-#{Date.today}",
             disposition:  "inline",
             layout:       "pdf",
             dpi:          "300",
             encoding:     "UTF-8",
             show_as_html: params[:debug].present?
    end
  end
end

查看代码：

# layouts/pdf.slim
doctype html
html
  head
    meta charset="utf-8"
    title
      = content_for?(:title) ? yield(:title) : 'Main Title'
    == wicked_pdf_stylesheet_link_tag "application", :media => 'all'
    == wicked_pdf_stylesheet_link_tag "print", :media => 'all'
    == wicked_pdf_javascript_include_tag 'vendor/modernizr'
    == csrf_meta_tags
  body data-action=action_name data-controller=controller_name data-format="pdf"
    main
      == yield
    == wicked_pdf_javascript_include_tag 'application'
    javascript:
      window.jQuery || alert("false");

# assessments/show.pdf.slim
= render "shared/cover", m: @assessment, t: "Individual"
= render "shared/about"
= render "shared/team", report: @report
# etc. etc. this is where the reports differ

# reports/show.pdf.slim
= render "shared/cover", m: @report, t: "Team"
= render "shared/about"
= render "shared/team", report: @report
# etc. etc. this is where the reports differ

然而，评估控制器的报告生成的pdf内容宽度稍窄，文本大小也相应较小 . 使用debug param渲染html会给出相同的页面，并且检查css显示没有差异 . 我使用Foundation作为css框架，但我认为这不重要 .

我读了一些关于wkhtmltopdf的 --disable-smart-shrinking 选项，但我修复了潜在的问题 . 我可以根据需要添加截图，但我认为问题应该在没有它们的情况下足够清晰 .

感谢您提供有关如何解决问题的任何帮助或使用wicked_pdf调整wkhtmltopdf选项 .
