title: Django - Increase FileField length
body: <p>I'm trying to store a file using a FileField, but the path of the destination of the file is larger than 100 characters. How can I increase the number of allowed characters? I've tried with max_length=255 but didn't work.</p>
  
  <p>Thanks.</p>
  
  <p>Edit: Added model</p>
  
  <pre><code>class File(models.Model):
      Record = models.ForeignKey(Records)
      Title = models.CharField(max_length=255, blank=False)
      File = models.FileField(upload_to='files/Records', blank=False)
      Upload_date = models.DateTimeField(auto_now_add=True)
  
      def __unicode__(self):
          return self.Title
  </code></pre>
