How to fix ActiveRecord::DangerousAttributeError?

Question

Ruby on Rails

Hello!
When submitting the form, this error pops up:

Here is student_controller.rb:

class StudentController < ApplicationController
  def index
  end

  def registration
    # @student = Student.new
  end

  def create
    @student = Student.new(student_params)
  end

  private def student_params
    params.require(:student).permit(:first_name)
  end
end

To be honest, I have no idea what the error is about. As I understand it, DangerousAttributeError speaks of some dangerous attributes. I translated the second line describing the essence of the problem, but did not understand it.
In general, explain to me, please, what exactly is the problem here?

Answer 1

If the student has a hash attribute, rename it.

Apparently first_name is reserved in ActiveRecord, try renaming it.
