import factory
from .models import Student, Course

class StudentFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = Student

    name = factory.Faker('name')

class CourseFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = Course

    name = factory.Faker('word')

    @factory.post_generation
    def students(self, create, extracted, **kwargs):
        if not create:
            return

        if extracted:
            for student in extracted:
                self.students.add(student)

# 创建一个学生
student = StudentFactory()

# 创建一个课程，并将其与学生关联
course = CourseFactory(students=[student])

# 创建多个学生并将它们与课程关联
students = StudentFactory.create_batch(size=5)
course = CourseFactory(students=students)
