地図表示への投稿の制限

Question

私は現在ウェブアプリケーションを構築しており、いくつかの問題が発生しています。 プッシュされている地図の表示記事が必要です（プッシュ== true）。そのために、私は多くの条件を試してみたいと思いますが、決してうまく動作しません。私は目標から遠くないと感じていますが、今のところマップは参照点がありません。

この段階のためにあなたが

def index 
@posts = Post.push #this will fetch the post with push true and sort it 
@hash = Gmaps4rails.build_markers(@posts) do |post, marker| 
#rest of your code 
end
