Rails: Naming conventions for attributes

Question

Im creating a model with the line

rails g scaffold contact firstname:string lastname:string email:string

But should the attributes be like

first_name:string 

instead?

Answer 1

Conventions aren't set in stone, but it's good to follow them.

And yes, widely spread convention for attribute names is snake case.

Snake case:

punctuation is removed and spaces are replaced by single underscores. Normally the letters share the same case (either UPPER_CASE_EMBEDDED_UNDERSCORE or lower_case_embedded_underscore) but the case can be mixed.
