Question

Given the following models:

User (id)
  has_many :groups
  has_many :communities

Groups (community_id (OPTIONAL) )
  belongs_to :user
  belongs_to :community

Communities (id, archived (boolean) )
  has_many :groups
  has_many :group_members, :include => :user

I can easily get a user’s groups by doing:

current_user.groups

The problem is if a community is archived, I don’t want that returned in the current_user.groups.

How can I get all of a user’s groups where the community is not archived?

Thanks

Answer 1

current_user.groups.joins(:community).where('communities.archived' => false)
