一  vue前端代码

实现的内容,通过对课程的分类,在每个不同的课程分类下显示相应的内容

序列化

class CourseCategorySerializer(serializers.ModelSerializer):    class Meta:        model = models.CourseDetail        fields = '__all__'    course_name = serializers.CharField(source='course.name')    recommend_courses = serializers.SerializerMethodField()    def get_recommend_courses(self, obj):        return [{
   'id': course.pk, 'name': course.name} for course in obj.recommend_courses.all()]
