comment how to check if the number is integer?
I think there is a confusion about mathematical and computational concepts of integer. The function is.integer checks the computational concept, the check.integer user function checks the mathematical point of view.

comment Reduce number of queries in ActiveRecord call
Actually there is no code.. As I said AtomType has many Atoms. It's just a relationship collections. It returns all atoms that belongs to that instance of AtomType.

comment Reduce number of queries in ActiveRecord call
It is, because when I pluck the id from atoms, that atoms belongs to the same AtomType. It's calling a relationship collection from an AtomType instance :)

revised VBA - Copy from Closed File paste to next available row on Summary Sheet
I removed the part where you ask for tips about VBA websites and references. Questions should always be very precise and focused on coding. Avoid asking for general tips or discussions that have no "correct" answer. :)

comment Authenticated login issue rails 4 with devise
It would be useful if you provide the log of what happens when you get the error page. Try heroku log -f to follow the log and try to login. Error details will show up on log :)
