More radio_buttons

I posted a question yesterday about radio buttons and got some good
feedback, but I don’t think I was asking the right question. I’m using a
group of three radio buttons to let me know if a user would like info
about there accounts sent to Home, Work, or Other. These values are
stored in a data base as booleans. Now, because of the was the helpers
are set up, it seems to me that I can’t have the buttons in a group
while still having them right the right database because of the “name”
attribute and how rails writes the html. For example, I need the radio
button Home to look something like this:

<%= radio_button_tag ‘user’, ‘d_home’, true, {:id => ‘user[d_home]’} %>

While the radio button for work looks like:

<%= radio_button_tag ‘user’, ‘d_work’, true, {:id => 'user[d_work] } %>

Other,

<%= radio_button_tag ‘user’, ‘d_other’, true, {:id => ‘user[d_other]’ }
%>

Now, these field would hit the database correctly, but they do not,
however, belong to the same group, which is what I need. Any ideas,
thanks
