    Just like Rahul said, there's no maxlength attribute for textarea in HTML. Only text input's have that.

    The thing you need to remember, is that RoR's text_area function (and all of RoR's HTML-generator functions) accept any argument you'll give them. If they don't recognized the parameter, then the'll just convert it to HTML.

    <%=f.text_area :data, :hellothere => "hello to you too"%>
    

    Will output this HTML:

    
    

    I know it's hard to remember, but Ruby on Rails isn't magic, it just does a lot of things for you. The trick is to know how it does them, so you can understand why they work, and how to fix them when they don't!
