Why does django create a migration file when we change the storage attribute of FileField, when the storage type is not stored in the database?
<p>I don't want to create a migration file whenever I change the storage of the FileField. I am getting the storage class from settings.py and it is configurable.</p>

<p>settings.py</p>

<pre><code>Storage =  S3BotoStorage(bucket='example')
</code></pre>

<p>models.py</p>

<pre><code> from django.conf import settings

 class myModel(models.Model):
        file = models.FileField(upload_to='', blank=True, storage=settings.Storage)
</code></pre>
