title: Access to file uploaded with FileField Django
body: <p>I'm trying to create a Django form with a filefield to upload a pdf based on a model.</p>
  
  <pre><code>#models.py
  class ProductionRequest(models.Model):
       ...
       contract_file = models.FileField('Contract file (PDF)', upload_to='contracts/')
       ...
  </code></pre>
  
  <p>I can upload the file and save it in my object, but when I try to show the file in my template with this code</p>
  
  <pre><code> {{ prod_req.contract_file }}
  </code></pre>
  
  <p>it only show me the path to the file
  "contracts/file_uploaded.pdf". How can I make a link to download (or open in a new tab ) the file ?</p>
  
  <p>Plus : when I try to open the file from Django admin, with this link</p>
  
  <p>Contract file (PDF) : Currently: contracts/file_uploaded.pdf </p>
  
  <p>I don't show me the file, i got this : </p>
  
  <p><code>Page not found (404) Request URL: http://127.0.0.1:8000/admin/appname/productionrequest/1/change/contracts/file_uploaded.pdf/change/</code></p>
  
  <p>How can I access to my file ?</p>
