drf-ModelSerializer 指定字段展示 和 排除字段展示 、字段替换

一、指定序列化字段

设置fields = '__all__'序列化所有字段。

class SnippetSerializer(serializers.ModelSerializer):
    class Meta:
        model = Student
        fields = '__all__'  # 序列化所有字段

class SnippetSerializer(serializers.ModelSerializer):
    class Meta:
        model = Student
        fields = ['student_no', 'student_name', 'student_sex', 'student_birthday', 'course', ]  # 表示序列化指定字段

二、排除字段

class SnippetSerializer(serializers.ModelSerializer):
    class Meta:
        model = Student
        exclude = ['student_name', 'student_sex', ]  # 指定排除的字段
