complicated nested finds

[thoraxe]

I'm building a report using the Trello gem, which is totally awesome! I am trying to find cards in lists that have particular labels, and am having a bear of a time figuring it out. I have lists that are called "sprint" (like agile) and then some cards in those lists have the "project" label.

Finding the sprints is pretty easy:

pmm_board.lists(:filter => :all).each do |list|
  if list.name.downcase.include? "sprint"
    sprint_lists << list
  end
end

And I will iterate over each list and then try to find its cards... but there doesn't seem to be a way to "find card with label" in any easy way.

So, given the cards in a particular list, eg sprint_lists[0].cards I am trying to do something like:

sprint_lists[1].cards.find { |card| card.card_labels.any? { |label| label["id"] == "54d4de9c74d650d5671cb3c7" } }

In other words, among the sprint_lists[1].cards i want to find any card whose card_labels array contains a label with the id of 54d4de9c74d650d5671cb3c7.

The nested enum-y/find-y thing above works, but only returns the first card in the list with that label.

Is there an easier way to find cards in a list with a particular label?
