I saw in a post that was not necessary to specify the type string for some column. But it didn't say which Rails he was using and the ruby guide put the :string anyway. In which version is that required ?

I don't know if it is necessary, but you have to set the type of the column in the DB, Rails can't decide for you (!). – MrYoshiji Sep 20 '13 at 13:23

Actually, it's not necessary. Look here, at the Rails::Generators::GeneratedAttributes#initialize source. You'll see the line:
@type = type || :string
So if you omit column type in generating model, it will be set by default to string. Thanks, BTW, it was nice to learn.
