我在控制器的create方法中得到一个无效的外键错误：

ActiveRecord::InvalidForeignKey in TytsController#create
SQLite3::ConstraintException: FOREIGN KEY constraint failed
app/controllers/tyts_controller.rb:7:in `create'

我检查了我的关联和控制器，认为它们设置正确：

class TytsController < ApplicationController

  def create
    if current_user.type == 'Student'
      @tyt = Tyt.new(tyt_params)
      @tyt.student_id = current_user.id
      @tyt.save
      redirect_to root_path
    else
      redirect_to root_path
    end
  end

  private

    def tyt_params
        params.permit(
          :student_id,
          :turkish_correct,
          :turkish_incorrect,
          :math_correct,
          .
          .
          .
          :chemistry_incorrect)
      end
  end

class Student < User
    attr_accessor :teacher_id

    has_many :connections, dependent: :destroy
    has_many :teachers, through: :connections, dependent: :destroy, foreign_key: "teacher_id"
    has_many :tyts, dependent: :destroy, foreign_key: "student_id"

end

class Tyt < ApplicationRecord

  belongs_to :student

end
