Rails验证发布请求

Question

Is there a gem or easy way to validate a API post request? For example I am always expecting a field to be either present or always a string and if it is not to ignore the request all together.

Or is the only way to do this is to manually check each request coming in with an IF statement?

Answer 1

一旦获得请求，请检查控制器中的参数，以及是否需要使用参数以允许发布->如果不向发布请求返回nil，则创建/更新数据库记录。

Answer 2

I think you should assign a Model to your "request". This way you could "validate" presence of any given fields
