ruby on rails - Prawn + Prawnto Issue -


I know that the shrimp is working because I have a show action that if I load the PDF load at the end of the show I add to Pdf.prawn. However, I have a form: 

  ; "/ holder" ,: action => "generated", format: "pdf "), & Gt; & Lt;% = label_tag (: number, "how many students?")% & Gt; & Lt;% = text_field_tag ​​(: calculation)% & gt; & Lt;% = hidden_field_tag: holder_id, value: @ holder% & gt; & Lt;% = submit_tag ("Generate Text Text")% & gt; & Lt;% end% & gt;   
 It counts for derivative actions.  
 I have the following in my generated action:  
  generates DR generic: file name = & gt; "Print.pdf" Answer_ | Format | Format.html format.pdf {Render: Layout = & gt; False} end-end   
 and my generated PDF looks like PRAN:  
  pdf.text "hello world"   
 When I submit the form I get the url:  http: // localhost: 3000 / gener.pdf  and chrome fails to load  PDF document  Errors or alerts  
 I found that I am getting:  Rated holder in my god log / generated.pdf.erb  which indicates that it is not searching for the .prawn file  
 What am I doing wrong?   
 
 
 Do your action as follows:    to generate a DR Respond_to | Format | Format.html format.pdf {info: filename = & gt; 'Print.pdf'} End End
