Question

我在我的 rails 项目中使用 chart.js 和 activeadmin 我有这个在我的行动中

controller do
  before_action :set_query, only: :index
  def index
    respond_to do |format|
      format.html
      format.pdf do
        render pdf: "file_name", javascript_delay: 3000, layout: "application_pdf.html.erb"
      end
    end
  end
end

我有这个想法

<canvas id="myChart" width="800" height="800"></canvas>
<script type="text/javascript">
    var ctx = document.getElementById("myChart");
    var myChart = new Chart(ctx, {
        type: 'bar',
        data: {
            labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
            datasets: [{
                label: '# of Votes',
                data: [12, 19, 3, 5, 2, 3],
                backgroundColor: [
                    'rgba(255, 99, 132, 0.2)',
                    'rgba(54, 162, 235, 0.2)',
                    'rgba(255, 206, 86, 0.2)',
                    'rgba(75, 192, 192, 0.2)',
                    'rgba(153, 102, 255, 0.2)',
                    'rgba(255, 159, 64, 0.2)'
                ],
                borderColor: [
                    'rgba(255,99,132,1)',
                    'rgba(54, 162, 235, 1)',
                    'rgba(255, 206, 86, 1)',
                    'rgba(75, 192, 192, 1)',
                    'rgba(153, 102, 255, 1)',
                    'rgba(255, 159, 64, 1)'
                ],
                borderWidth: 1
            }]
        },
        options: {
            scales: {
                yAxes: [{
                    ticks: {
                        beginAtZero:true
                    }
                }]
            }
        }
    });
</script>

我的 application_pdf.html.erb 布局中有以下内容

<%= wicked_pdf_javascript_include_tag "active_admin.js" %>
<%= wicked_pdf_javascript_include_tag "Chart" %>

图表在 html 中正确显示，但在 pdf 中我看不到它们我在这里做错了什么？

我发布这个答案是为了帮助其他人我只是将响应选项设置为 false，一切都开始正常工作

options: {
  responsive: false
}
