How to pass foreign key id as parameter while calling create form in rails 4.x

My user interface needs to be such that a student record can be created:

1) by a student if he/she is over 18 years
OR
2) has to be created by parent if the student is <18 years.

In the student form, I have the Date of birth field, which I can use for that isadult validation, but I'm a little confused how to go about the logic above in general.

I am guessing it can be implemented as passing a parent_id parameter value to the http://localhost:3000/student/new form call. When the user indicates that he is an adult, the parent_id parameter value wont be included, otherwise, if the user is already logged in as a parent, then that parent_id would be passed to http://localhost:3000/student/new?parent_id=1 (say).

Im struggling to understand how this is going to be implemented. Need some sample code for implementation. Please Feel free to ask questions.

As Iceman suggests, you don't need to pass the parent_id as a parameter. In the controller's create, you can do something like

@student = Student.new(params)
@student.parent_id = @current_user.id if @current_user.isadult?

In the Student model you can add a validation that the current user is over 18 or has a parent id
