Question

我正在使用邪恶的PDF gem为我的应用程序生成PDF。我的控制器中有一些逻辑，一段时间以来一直生成带有页脚和页码的PDF。

我现在需要在我的模型中生成这个PDF，并且由于移动控制器将pdf代码渲染到模型，因此它没有呈现页脚或适当的边距。

这是我的控制器中的代码：

WickedPdf.new.pdf_from_string(
    render  :pdf => "#{@user.id}_#{@paper.data["statementDate"]}",
            :template => "statements/monthly_statement_templates/#{@paper_template}",
            :footer => { :html => { template: 'statements/monthly_statement_templates/footer.pdf.erb' }},
            :title => "#{@paper.data["statementDate"]} Statement",
            :locals => { :statement => @paper.data },
            :margin => {
              :bottom => 20,
              :top => 20
            }

我已将代码移至模型中。它看起来如下：

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

# Need these in case the view constructs any links or references any helper methods.
av.class_eval do
  include Rails.application.routes.url_helpers
  include ApplicationHelper
end

statement_pdf = WickedPdf.new.pdf_from_string(
      av.render :pdf => "#{statement.id}",
        :template => "statements/monthly_statement_templates/#{statement_template}",
        :footer => { :html => { :template => 'statements/monthly_statement_templates/shared/footer.pdf.erb' }},
        :locals => { :statement => statement.data },
        :margin => { :bottom => 20, :top => 20 }
    )

比较两个PDF时，模板中的所有数据和样式都是相同的。但是，从模型渲染PDF时，它不包括具有一些文本和页码的页脚。

我的页脚如下：

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <%= stylesheet_link_tag "https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" %>
    <style type="text/css">
      .legal { font-size: 8px; }
    </style>
    <script>
      function number_pages() {
        var vars={};
        var x=document.location.search.substring(1).split('&');
        for(var i in x) {var z=x[i].split('=',2);vars[z[0]] = unescape(z[1]);}
        var x=['frompage','topage','page','webpage','section','subsection','subsubsection'];
        for(var i in x) {
          var y = document.getElementsByClassName(x[i]);
          for(var j=0; j<y.length; ++j) y[j].textContent = vars[x[i]];
        }
      }
    </script>
  </head>

  <body onload="number_pages()">
    <div class="container">
      <div class="row">
        <div class="col-xs-12">
          <div class="col-xs-9 legal">
          </div>
          <div class="col-xs-3 pull-right legal">
            <small>Page <span class="page"></span> of <span class="topage"></span></small>
        </div>
      </div>
    </div>
  </body>
</html>
