Send_data not sending pdf（WickedPdf）

Question

我正在嘗試爲用戶下載生成pdf。我正在使用WickedPdf寶石。

<%= simple_form_for :report, url: [:download, :admin, :reports], format: :pdf, method: :get, remote: true do |f| %> 
    <%= f.input :event, collection: @events %> 
    <%= f.input :report_type, collection: [:schedule, :overview] %> 
    <%= f.submit "Download" %> 
<% end %> 



class Admin::ReportsController < Admin::BaseController 

    def index 
    @events = Event.all 
    end 

    def download 
    respond_to do |format| 
     format.pdf do 
     pdf = WickedPdf.new.pdf_from_string(pdf_string) 
     send_data pdf, :filename => "report.pdf", :type => "application/pdf" 
     end 
    end 
    end 

    private 

    def pdf_string 
    render_to_string(template:'admin/reports/pdf/schedule_overview.html.erb', layout: false) 
    end 

end 

應用程序/視圖/管理/報告/ PDF/schedule_overview.html.erb

This is a pdf 

（只是文本ATM）

服務器請求時：
