Simple form: set current_user.username as value for commenter
<p>I want to set the name of the current user as the value for the commenter. </p>

<p>when i use: <code>&lt;%= f.input :commenter, :input_html =&gt; { :value =&gt; '&lt;% current_user.username %&gt;' }, label: false, disabled: true %&gt;</code> I get a syntax error.</p>

<p>Actually, I don't want to display the commentor on adding the comment; only on the listing.</p>

<p>Besides Simple_form, I use Devise.</p>
