Ruby on rails rake db:seed错误：缺少关键字：from、to

我准备了一个数据库来测试我的代码。当我运行rakedb:seed对数据库进行种子设定时，我得到以下错误

我希望控制台是空的：这意味着数据已经被植入种子

错误：

看起来你在用Faker的旧语法。它最近更改为需要关键字参数而不是位置参数

您需要遵循更新的语法：

Faker::Date.between(from: 2.days.ago, to: Date.today) #=> "Wed, 24 Sep 2014"

注意指定参数的关键字from:和to:。参数的顺序并不重要，相反的顺序也同样适用：

Faker::Date.between(to: Date.today, from: 2.days.ago) #=> "Wed, 24 Sep 2014"
