Hi,
I''d like to be able to query a ''result set'' without
hitting the db again
for example:
In my controller:
Def show
#load somel widgets
@widgets = Widgets.find_all(''type = 1 or type = 2'')
End
In my view:
<% @type1 = @widgets.find_all(''type = 1'') %>
<% @type2 = @widgets.find_all(''type = 2'') %>
I tried this in Rails 12.0 but additional db hits were created.
Thanks,
Nev

A local variable is probably all you need in the view.
