Is it necessary to put column:string on rails 3/4 generate model?

Question

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 ?

Answer 1

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.
