To help myself learn ruby and rails, I am implementing a todo list
manager. Every task can have sub tasks (and so on.)
I am using betternestedset
Until this point, I have been getting everything and then only
displaying if it is not done OR it has been updated in the last day.
(If you don''t display a parent, you don''t display any of its
children.)
However, it seems to me that this should be done in the getting of
data instead of the displaying of it.
I can do this for the root trees:
<code>
one_day_old = Date.today - 1
find(:all, :conditions => "(user_id = #{user.id}) AND
((done = ''f'') OR (updated_at
>''#{one_day_old}'')) AND
((parent_id IS NULL) OR (parent_id 0))",
:order => "lft")
</code>
However, then when I query the children I still get ones that I don''t
want to show.
It looks like full_set with the exclude string may be the right way to
go, but I can''t quite figure it out. (Or if there is a more
"rails-y"
way to go about this....)
Any suggestions?
