FileField from schema.extender

[Benjamin Klups]

I create a FileField in schema.extender but i don't know how to view it in my template
i put :
          <div tal:condition="context/myfield">
  < span tal:replace="context/myfield"/>
           </div>    

and i can see the content of the file but i just want to view a link to the uploaded file

i'm a poor beginner

thanks for your advices
