Python - SqlAlchemy: Filter query by great circle distance?

Question

I am using Python and Sqlalchemy to store latitude and longitude values in a Sqlite database. I have created a hybrid method for my Location object,

@hybrid_         


        

Answer 1

It does look like you've done everything correctly, but somehow the method is not actually getting 'hybridized'. Could you have done something stupid, like not actually put the decorator on in your source code?
