heroku - operator does not exist: numeric #69

Has any one tested with Postres database?

jspooner commented 13 years ago

I learned that you have to cast variables like this lng::numeric but still haven't finished a working version.

I started a fork for it here https://github.com/jspooner/geocoder/blob/master/lib/geocoder/stores/active_record.rb

alexreisner commented 13 years ago

What data type is your lat column? You shouldn't have to cast if it's a float. A lot of people (myself included) are using Geocoder with Postgres and on Heroku and haven't had this problem so we'll have to figure out what's different about your environment and/or app.

ha. my lat/lng columns were created long before geocoder and were set to string. I'll change it to float and close this issue if it works. Thanks for the great gem.
