class LocationLog(models.Model):
    user = models.ForeignKey(User)
    utm = models.GeometryField(spatial_index=True)

This is my database model. I would like to insert a row.

I want to insert a circle at point -55, 333. With a radius of 10. How can I put this circle into the geometry field?

Of course, then I would want to check which circles overlap a given circle. (my select statement)
