Question

I am doing the following:

@group_coach = GroupCoach.find(“groups_count < ‘9’” )

I have a groups_count column in my db that is being updated by a counter_cache => true method in the Group model.

I know this isn’t right. Because the error it spits out: Couldn’t find GroupCoach with ID=groups_count < ‘9’

I have reviewed the Rails Guides:

client = Client.find(10)

Client.where(“orders_count = ‘2’”)

The second option does run in the localhost but isn’t actually returning a GroupCoach… It just returns groupcoach…

What is the proper syntax for this?

Answer 1

Have you tried:

@group_coach = GroupCoach.where("groups_count < 9")

To clarify: @group_coach will be a collection of records. So you can’t call @group_coach.name because all that will do is give you “GroupCoach” (the name of the class). Instead, you would need to iterate over the items:

@group_coach.each do |group_coach|
  puts group_coach.name
end
