I am learning django version 1.11.4 through tutorial on the official documentation. I am using python 3.6.5 and mysql8 for database. I also use mysql.connector.django to connect to mysql database. I tried to do the first Django app, part 2.

这是我使用的示例的链接

一切正常，除非我运行以下命令:

everything works fine except when I run the this command:

Question.objects.all()

模型文件中使用的代码:

the code used in the models file :

import datetime

from django.db import models

from django.utils import timezone

class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

    def was_published_recently(self):
        return self.pub_date >= timezone.now() - 
        datetime.timedelta(days=1)

    def __str__(self):
        return self.question_text



class Choice(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)

    def __str__(self):
    return self.choice_text

数据库设置:

DATABASES = {
    'default': {
        'NAME': 'mysite',
        'ENGINE': 'mysql.connector.django',
        'USER': 'root',
        'PASSWORD': '********',
        'OPTIONS': {
          'autocommit': True,
        },
    }
}

任何解决此错误的线索或帮助将不胜感激.

any clue or help to fix this error will be appreciated.

推荐答案

在 @ Alasdair提供的解决方案是:

在DATABASES['default']['OPTIONS']中设置use_pure=True.
