Question

In user model I’ve got attribute location of type point. Now I’ve got a validation code:

validates :location, :format => { :with => /\(-?\d+(?:\.\d+)?,-?\d(?:\.\d+)?\)/,
                                    :on => :update,
                                    :if => :location_changed? }

It works fine in console, on localhost, but on heroku it returns:

Processing by UsersController#update as / 2012-07-31T18:14:37+00:00
app[web.1]: Parameters:
{“user”=>{“location”=>”(3.545452,2.4353534)”}, “id”=>”self”}
2012-07-31T18:14:37+00:00 app[web.1]: Completed 500 Internal Server
Error in 13ms 2012-07-31T18:14:37+00:00 app[web.1]:
2012-07-31T18:14:37+00:00 app[web.1]: NoMethodError (undefined method

2012-07-31T18:14:37+00:00 app[web.1]:
app/controllers/users_controller.rb:16:inupdate’

Actually it works also great in heroku console, but don’t work in curl request.

Rails version 3.2.7.

attr_accessible :profile_picture, :password, :location

Thanks!

It looks like a magic. I fixed it with recreation if table and server restart. Very strange.
