Something like this for your first two questions?
<% POSSIBLE_CATEGORIES.each do |web|%>
<% if option_checked(web) %>
<%= check_box_tag web, ''1'',
true%><%= web %><% else %>
<%= check_box_tag web %><%= web %><% end%>
<% end %>
Where POSSIBLE_CATEGORIES is an array of what you want the check boxes
to represent, ''1'' is the value of a checked check box, and
true defaults
it to checked.
option_checked(web) is a method in ApplicationHelper that compares the
name of the check box (gotten from POSSIBLE_CATEGORIES) to something
stored in the database. You could easily modify it for the true/false
that you want.
Sorry if I misunderstand/this doesn''t solve your problem (and
there''s
probably a better way to do this, but this works for me).
