有可能做一个双has_many:通过rails中的关联？

class CreateEnrollments< ActiveRecord::Migration[6.1]
  def change
    create_table :enrollments do |t|
      t.integer :student_id
      t.integer :course_id

      t.timestamps
    end
  end
end

class Student< ApplicationRecord
  has_many :enrollments
  has_many :courses, through: :enrollments
end

class Course< ApplicationRecord
  has_many :enrollments
  has_many :students, through: :enrollments
end

# 创建一个新的学生和课程
student = Student.create(name: "John")
course = Course.create(name: "Math")

# 将学生添加到课程中
student.courses<< course

# 获取学生的课程列表
student.courses

# 获取课程的学生列表
course.students
