ruby on rails - export data to csv without changing pages -

what proper way export data csv file rails.

i have "export" link in views

shows.html.erb

 <%= link_to "csv", patient_record_path(format: "csv") %> 

patient_record_controller

def show      ....     respond_to |format|         format.html         format.csv {         send_data restclient.get(url, :accept => :csv), :type => 'text/csv; charset=iso-8859-1; header=present', :disposition => "attachment; filename=data.csv"         }     end end 

when click export error

template missing  missing template patient_record/show, application/show {:locale=>[:en], :formats=>[:csv], :handlers=>[:erb, :builder, :coffee]}. searched in: * "/rubymineprojects/my_app/app/views" 

it redirected url

http://www.host.com/patient_record/1.csv 

i shouldnt redirecting pages, want export csv file , keep on same page

if use ajax, functionality works fine, file doesn't show being downloaded in broser

you doing request 'show' , throwing error because looking show.html.erb file within patients records controller. possible avoid page redirecting if used jquery + ajax issue request doing this:

$('#export_link).on ("click", function(e) {   e.preventdefault();   $.ajax({     url: whatever_the_patient_record_path_is,     etc........   }); });
