title: Saving a vector in Django Sqlite3
body: <p>I am trying to store a vector using Django in Sqlite3 using the following Model Field</p>
  
  <pre><code>vector = models.CharField(validators=[int_list_validator(sep=' ', allow_negative=True)], max_length=256)
  </code></pre>
  
  <p>and the corresponding Serializer Field</p>
  
  <pre><code>vector = serializers.CharField()
  </code></pre>
  
  <p>Before saving the instance the vector has a shape of (1,128) and on retrieval from database it isn't of required shape.</p>
  
  <p>Is it the correct way of saving a vector or an alternate solution exists?</p>
  
  <p>Thanks for your help!  </p>
