我正在尝试在模型序列化器中添加一个新字段，该字段将向另一个模型显示该模型的所有相关值。

models.py

from django.db import models

class University(models.Model):
    name = models.CharField(max_length=50)

    def __unicode__(self):
        return self.name

class Student(models.Model):

    last_name = models.CharField(max_length=50)
    university = models.ForeignKey(University)

    def __unicode__(self):
        return '%s %s' % (self.first_name, self.last_name)

views.py

from rest_framework import viewsets
from .models import University, Student
from .serializers import UniversitySerializer, StudentSerializer

class StudentViewSet(viewsets.ModelViewSet):
    queryset = Student.objects.all()
    serializer_class = StudentSerializer

class UniversityViewSet(viewsets.ModelViewSet):
    queryset = University.objects.all()
    serializer_class = UniversitySerializer

serializers.py

from rest_framework import serializers
from .models import University, Student

class UniversitySerializer(serializers.ModelSerializer):
    class Meta: …
