Question

In my ruby(1.9.3) on rails (3.1) app I’m trying to set some conditional behavior with respect to tasks and deadlines. Specifically the coloring of a progress bar.

Tasks belongs_to list
List has_many tasks

I’m essentialy trying to see if the last task.planned_for date in @list.tasks is past @list.deadline.

Both list.deadline and task.planned_for are :date types.

So in my view I’m looking for something like:

- if @last_task.planned_for > @list.deadline

Where

@tasks = @list.tasks.todo
@last_task = @tasks.last

Any ideas on how to best do this. This (obviously) isn’t working.

Answer 1

Your @tasks.last doesn’t grab the latest one, it grabs the last one in the database, not in any particular order. You probably want to get it with

@last_task = @list.tasks.order('planned_for DESC').first`  

(by ordering it descending, the first date is latest)
