如何使这个简单的方法更短？

Question

我的应用程序中有非常简单的方法.我想知道是否有办法让它更短.

def is_enough_words_to_play_game?
    if Word.verified.size > 5
        true
    else
        false
    end
end

Answer 1

你可以写:

def is_enough_words_to_play_game?
  Word.verified.size > 5
end

因为Word.verified.size > 5返回已经是布尔值.

或恕我直言更可读:

MIN_WORDS_FOR_GAME = 6

def enough_words?
  Word.verified.size >= MIN_WORDS_FOR_GAME
end
