django - 在 Django 中执行右连接

Question

这是我的模型

class Student:
    user  = ForeignKey(User)
    department = IntegerField()
    semester = IntegerField()
    ...

class Attendance:
    student = ForeignKey(Student)
    subject = ForeignKey(Subject)
    month = IntegerField()
    year = IntergerField()
    present = IntegerField() 
    total = IntegerField()

students = Student.objects.filter(semester=semester)

如何在 Student 之间执行正确的连接和 Attendance模型，这样我就可以得到
带有所有 students 的查询集和出勤率是否存在于学生，否则为空？

文档提到了左连接但没有提到右连接。

Answer 1

更改表主题的左连接

queryset.query.alias_map['subject'].join_type = "RIGHT OUTER JOIN"
