title: utf8' codec can't decode byte 0x89 in position 15: invalid start byte
body: <p>This is a view for my project in which I am trying to upload images from my local system to s3 using boto. </p>
  
  <pre><code>class ImageList(generics.ListCreateAPIView):

  <p>It works fine for django admin but generates error while I try to upload it using Django Rest Framework html form. I have overridden the post method in generic class based view. The error that gets generated is :</p>

  <p>I have tried almost everything available on stack overflow but nothing worked for me. I didn't copy the code from somewhere so there would be no strange characters.</p>
  
  <p>For reference this is the  <strong>models.py</strong> file: </p>
  
  <pre><code>class Image(models.Model):
      image_meta = models.ForeignKey('Image_Meta',on_delete=models.CASCADE,)
      image = models.ImageField(upload_to='images-data')
      # image = models.URLField(max_length = 500)
      order = models.IntegerField()
      version = models.CharField(max_length=10)
  
      def __unicode__(self):
              return (self.image)
