Rails路由强制param存在

I'm fairly new to ruby api development and have created the below endpoint in my routes.rb

我对ruby api开发相当新，并在我的routes.rb中创建了以下端点

get "/users/active_users/:since"

However, when the param is not given, I want the param to default to a certain value. How do I enforce this? Also, I want to enforce that param be an integer and not alpha/alpha-numeric. Help is appreciated!

但是，当没有给出参数时，我希望param默认为某个值。我该如何执行？此外，我想强制该param是一个整数而不是alpha / alpha-numeric。感谢帮助！

#1

get "/users/active_users/:since"

By making this routes its compulsory to give the params[:since] , other wise it will throw back a error not routes matches

通过使这条路线成为强制给出params [：since]，其他方面它会抛出错误而不是路线匹配

So here by i would suggest you to make routes

所以我建议你做路线

get "/users/active_users"

Since it's get type request so its won't affect more, you can append params[:since] in query with routes like this:-

因为它是获取类型请求所以它不会影响更多，你可以在查询中添加params [：since]与这样的路由： -

/users/active_users?since=1999

And at your controller you will get params[:since] = 1999

在你的控制器你会得到params [：since] = 1999

So far as i know it can't be enforce routes to accept only integer params but it can be handle at controller side

据我所知，它不能强制路由只接受整数参数，但它可以在控制器端处理

params[:since].is_a? Integer
=> true

要么

params[:since].to_i

#1

get "/users/active_users/:since"
