How to create the geometry column in flask model

   from geoalchemy2 import Geometry
   from app import db
   class process(db.Model):
      wkt = db.Column(Geometry('POINT'))

但是在创建 table

时出错

create table process(
[WKT] geometry(GEOMETRY,-1) NULL)

SQL 错误是：

Incorrect syntax near ','.

Answer 1

It's tricky, I tried this one

WKT = db.Column(Geometry(''))
