How to create LineStringField in MongoEngine?

Question

I would like to know how to create an object with a LineStringField in MongoEngine. With a model like that:

class Line(Document):
    line = LineStringField()
    owner = ReferenceField(User)

    meta = {
        'indexes': [[("line", "2dsphere"), ("owner", 1)]]
    }

I would do something like that:

shape = Line(owner=user, line={type:"LineString",coordinates:[[0,2],[2,0],[2.5,1.2]]})
shape.save()

But I feel like I am overwriting the preset "type" attribute of the predefined LineStringField.

You can either pass a dictionary with the full geoJSON information or a list of point pairs. eg:

Line(owner=user, line=[[0,2],[2,0],[2.5,1.2]]).save()
