wicked_pdf 没有收益内容

Question

<%= wicked_pdf_stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
<%= wicked_pdf_javascript_include_tag "application", "data-turbolinks-track" => true%>

def show
  @invoice_items = @invoice.accounts_receivables_items

  respond_to do |format|
    format.html { render :template => "invoices/show"}
    format.pdf  {render :pdf => "invoices/show",
                        :template => 'layouts/application.html', formats: :html, encoding: 'utf8', :show_as_html => params[:debug].present?}
  end
end

我明白了。这是我的网页（layout/application.html），但没有 <%= yield %> 内容

Answer 1

因为您指定:template 为您的布局文件，所以它会在没有视图的情况下呈现您的布局。

更像这样的东西怎么样（注意模板和布局键）：

render pdf: "invoice",
       layout: 'layouts/application.html',
       template: 'invoices/show',
       formats: :html,
       encoding: 'utf8',
       show_as_html: params[:debug].present?
