问题 I recently found that multiple after_commit s defined in the same model get called in reverse order. For example after_commit method1, :on => :create after_commit method2, :on => :create method2 gets called before method1 . Is it always called in FILO order? 回答1: This behaviour is still present in Rails 5.2.2.1. My solution: after_commit :after_commit_callbacks, :on => :create def after_commit_callbacks method1 method2 end 来源： https://stackoverflow.com/questions/30625790/execution-order-of

问题 Given a init date and today, what's the query to search for all "names" between that date? Thank you 回答1: MongoMapper You should be able to use MongoMapper's query operators. Suppose your have a "User" model with a "created_on" date, you could use this to get the names. (I believe MongoDB uses UTC Times to store all date/time objects): initial_date = Time.utc(2011, 5, 1) # 2011-05-01 00:00:00 UTC @users = User.where(:created_on => {:$gte => initial_date, :$lte => Time.now.utc}) @users.each do
