How to avoid conflicting when naming model attributes?

Question

I want to know if there is a best to name model attribute that won't conflict with ActiveRecord::Base instance methods.

For example, we probably won't name attribute as class or toggle, since these names have already been taken. But how do I simply know if the name is conflicted when generating a model? Any ideas?

Answer 1

Fire your console at first

 > a = MyModel.new
 > a.methods.grep(/my_attr/)

If nothing, nice, you can use my_attr
