Format DateTime in Text Box in Rails

Is there an easy way to format the display of a DateTime value in a Rails view?

For example, if I'm doing something like:

<%= text_field :my_object, :start_date %>

and only want to display the Date part of the :start_date (i.e. I want to hide the time part), is there a way to format the :start_date string inside of the view such that it will work for creating new my_object items and updating new my_object items?

Just a clarification:

Doing

<%= text_field 
       :my_object,
       :start_date,
       :value => @my_object.start_date.strftime('%m/%d/%Y') %>

works beautifully when the object already exists (i.e. on item updates), however, when creating a new item, since start_date will initially be nil, the view will throw an error

while evaluating nil.strftime

Some great suggestions here, however in those cases where you really do want your text field date formatted a specific way (say you're integrating with a javascript date picker), and you're dealing with nils, I think simply making a minor tweak to your existing method would do the trick:

:value => (@object.start_date.blank? ? '' : @object.start_date.strftime('%m/%d/%Y'))
