Rails NoMethod Error calling dynamic find attribute

I am currently working on an application. In this application, I created the Person model, and I used the dynamic attribute search function. In the Person model, I have a uid attribute, so I called Person.find_by_uid (some numerical value). This worked fine in my development mode and the application was fully functional. However, as soon as I deployed this application to the hero. The application failed, and the log complains about NoMethodError (undefined method is `find_by_uid 'for #):

I looked at all the places, but still could not track the problem. I tried to define the find_by_uid method within the framework of the Person model and still does not work.

I was wondering if anyone has similar experience or does he know how to solve this problem?

Thank you very much for your time!

Have you tried running migrations to heroku (heroku rake db: migrate)? In most cases, this attribute is not contained in the heroku database, so you do not have this dynamic method.
