    name = models.CharField(verbose_name='姓名', max_length=1024, default="",blank=True, null=True)
    age = models.CharField(verbose_name='年龄',max_length=30,blank=True, null=True,help_text='年龄')
    face = models.ImageField(upload_to='pic')
    create_time = models.CharField(max_length=30,verbose_name='时间', blank=True, null=True)

    class Meta:
        db_table = 'people'
        verbose_name = '人物信息'
        verbose_name_plural = verbose_name

• serializer.py的内容

class PeopleSerializer(serializers.ModelSerializer):
    face = serializers.ImageField(max_length=None, use_url=True)

    class Meta:
        model = People
        fields = ("__all__")
