How to set title for text_field?

问题

I know that is something simple, but I'm stuck. I have a several forms in my rails3 app to which I need to add tooltips, by using the tipsy. The text in tooltips should be determined in title\original-title, but I just can't figure it out, how to set it for text_field.

<%= f.text_field :what %>

gives me

<input id="name_which" name="name[which]" size="30" type="text">

and I just can't figure it out, where to put the title text.

For example, this one in html works fine

<input type="text" name="tooltipform" title="Tooltip text">

In application.js it is determined by

$(window).load(function() {
$('#form-example [title]').tipsy({trigger: 'focus', gravity: 'w'});

});

I know that is something basic and I'm ashamed of my self. Thank you in advance.

It's quite simple, pass it as an option:

<%= f.text_field :what, :title => "Tooltip text %>

Other html attributes can also be set as this, such as :class, :id, etc.

Try with:

<%= f.text_field :what, :title => 'whatever' %>
