ruby on rails add div on error messages join
===

current code for the ajax call:

    @return = { :error => true, :response => @invitation.errors.full_messages.join("<br />") }

the errors now appear as

    Email can't be blank
    Email is invalid

how can i add a `div` before the error messages and a `p` tag in each line?

so it would become


    <div>
        <p>Email can't be blank</p>
        <p>Email is invalid</p>
    </div>
