if i got a couple of radio buttons on my form that i want to use a  
published\_at field rather than a boolean field how would i go about  
this? I know that if i’m using a boolean i can do the following.

\<%= f.radio\_button :published\_at, true %\> Yes  
\<%= f.radio\_button :published\_at, false %\> No

but what would i have to change to use the datetime field?

many thanks in advance guys,

Are you expecting people to enter a date or to choose between one of  
several dates ?

Ah, so that’s more than a radio button. it’s some radio buttons + your  
favourite date input method, together with a chunk of javascript that  
does stuff to those input controls.  
The radio\_button would be for a separate attribute (which might not  
even be a real one) to published\_at

Hi,

i was actually hoping for when they check the yes option is puts the  
current time in the field. and when they click no it is removed.

Not massively difficult. Not a rails issue at all though - get out  
your html and javascript books to find out about event handling and so  
on.

searched for examples online and in my rails books but cannot find  
anything.
