Hi, everyone!

What is a good way to store a enum value in the ActiveRecord? For example, I have a User model. The User has a "gender" that can only be :not_specified, :male, or :female.

Hi, Marnen!

What is a good way to store a enum value in the ActiveRecord?

You might want to use composed_of or maybe even an association.

Thanks, I'll look into it.

For example, I have a User model. The User has a "gender" that can only be :not_specified, :male, or :female.

Do you know yet what the DB side of this will look like?

No, but I will appreciate an advice on the DB side of the things.

Cheers, Gleb

For now I settled with this gem http://github.com/jeffp/enumerated_attribute/tree/master

But, frankly, I was surprised how difficult it is to do Java-like enums (enums that can have instance methods).

Still, since for now I only need enums for gender and marital status, this will do.

Thanks!

Cheers, Gleb

I'll check that out. I hadn't heard of it.

What part is difficult about that? True, Ruby doesn't have a native Enum class that I know of, but I would think it would be easy to make one.

OK.

Thanks!
