您好，函数是这样的

@python_2_unicode_compatible
class ArticleQuerySet(models.query.QuerySet):
   """自定义QuerySet，提高模型类的可用性"""

   def get_published(self):
       """返回已发表的文章"""
       return self.filter(status="P").select_related('user')

my.cnf文件是这样的，默认设置

[zanhu@zanhu ~]$ cat /etc/my.cnf

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/8.0/en/server-configuration-defaults.html

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

# innodb_buffer_pool_size = 128M

#

# Remove the leading "# " to disable binary logging

# Binary logging captures changes between backups and is enabled by

# default. It's default setting is log_bin=binlog

# disable_log_bin

#

# Remove leading # to set options mainly useful for reporting servers.

# The server defaults are faster for transactions and fast SELECTs.

# Adjust sizes as needed, experiment to find the optimal values.

# join_buffer_size = 128M

# sort_buffer_size = 2M

# read_rnd_buffer_size = 2M

#

# Remove leading # to revert to previous value for default_authentication_plugin,

# this will increase compatibility with older clients. For background, see:

# https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_default_authentication_plugin

# default-authentication-plugin=mysql_native_password

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

创建数据库的时候是 CREATE DATABASE zanhu charset utf8;
