CodePudding user response：

The developer_id is nested under project just like the other params.

developer_id = params[:project][:developer_id]

developer_id = params.dig(:project, :developer_id)

When you are unsure where to find certain params or if they even exist then the easiest way is certainly to look into your applications log file. There you should see the incoming request and all the params and how they are nested.
