ensure_inclusion_of should accept array as parameter

[vpereira]

Hi,

I have a validation like

validates :boolean_field, :inclusion => { :in=>[true, false] }

it would be great to do something like:

it { should ensure_inclusion_of(:boolean_field).in_array [true,false] }

I agree with this; I assumed that this already existed but was disappointed to see that it didn't.

yes, I did a quick patch to work, you can check my git pull request, however ideally it should work in any enumerable so maybe with some syntax sugar we could do something like

it { should ensure_inclusion_of(:attr).in_enumerable ()

Looks like discussion has moved to #71, so I'm closing this. Thanks for the pull request, @vpereira!
