title: Save multiple files using FileField
body: <p>In a existing form I use a <code>FileField</code> to attach differents type of files <code>.txt, .pdf, .png, .jpg, etc</code> and work fine but now I need that field to accept several files, so I use the propertie <code>multiple</code> for the input to accept more of one files but when is stored in my database only stored the path for the first selected file and in the media folder are only stored one file no the others, this is what I have:</p>
  
  <pre><code>forms.py
  class MyForm(forms.Form):
      attachment = forms.FileField(required=False,widget=forms.ClearableFileInput(attrs={'multiple': True}))
  
  models.py
  class MyFormModel(models.Model):
      attachment = models.FileField(upload_to='path/', blank=True)
  </code></pre>
  
  <p>Is posible to store in the DB all the paths separete in this way <code>path/file1.txt,path/file2.jpg,path/file3.pdf</code> and store the three files in the media folder? Do I need a custom <code>FileField</code> to procces this or the view is where I need to handle this?</p>
  
  <p><strong>EDIT:</strong> The answer @harmaahylje gives me comes in the docs but not for the versión I use 1.8 this affect the solution?</p>
