## models代码： ##

# -*- coding: utf-8 -*-
    
    from __future__ import unicode_literals
    
    
    # Create your models here.
    import sys
    
    from django.db import models
    from django.contrib.auth.models import User
    
    from django.utils.translation import gettext_lazy as _
    
    JobTypes = [
        (0, "技术类"),
        (1, "产品类"),
        (2, "运营类"),
        (3, "设计类"),
        (4, "市场营销类")
    ]
    
    Cities = [
        (0, "北京"),
        (1, "上海"),
        (2, "深圳"),
        (3, "杭州"),
        (4, "广州")
    ]
    
    
    class Job(models.Model):
        # Translators: 职位实体的翻译
        job_type = models.SmallIntegerField(blank=False, choices=JobTypes, verbose_name=_("职位类别"))
        job_name = models.CharField(max_length=250, blank=False, verbose_name=_("职位名称"))
        job_city = models.SmallIntegerField(choices=Cities, blank=False, verbose_name=_("工作地点"))
        job_responsibility = models.TextField(max_length=1024, verbose_name=_("职位职责"))
        job_requirement = models.TextField(max_length=1024, blank=False, verbose_name=_("职位要求"))
        creator = models.ForeignKey(User, verbose_name=_("创建人"), null=True, on_delete=models.SET_NULL)
        created_date = models.DateTimeField(verbose_name=_("创建日期"), auto_now_add=True)
        modified_date = models.DateTimeField(verbose_name=_("修改日期"), auto_now=True)

### 解决办法： ###

在models中加：

reload(sys)
    sys.setdefaultencoding("utf8")

### models完整代码如下： ###

# -*- coding: utf-8 -*-
    
    from __future__ import unicode_literals
    
    
    # Create your models here.
    import sys
    
    from django.db import models
    from django.contrib.auth.models import User
    
    from django.utils.translation import gettext_lazy as _
    reload(sys)
    sys.setdefaultencoding("utf8")
    JobTypes = [
        (0, "技术类"),

    ]
    
    Cities = [
        (0, "北京"),
        (1, "上海"),
        (2, "深圳"),
        (3, "杭州"),
        (4, "广州")
    ]
    
    
    class Job(models.Model):
        # Translators: 职位实体的翻译
        job_type = models.SmallIntegerField(blank=False, choices=JobTypes, verbose_name=_("职位类别"))
        job_name = models.CharField(max_length=250, blank=False, verbose_name=_("职位名称"))
        job_city = models.SmallIntegerField(choices=Cities, blank=False, verbose_name=_("工作地点"))
        job_responsibility = models.TextField(max_length=1024, verbose_name=_("职位职责"))
        job_requirement = models.TextField(max_length=1024, blank=False, verbose_name=_("职位要求"))
        creator = models.ForeignKey(User, verbose_name=_("创建人"), null=True, on_delete=models.SET_NULL)
        created_date = models.DateTimeField(verbose_name=_("创建日期"), auto_now_add=True)
        modified_date = models.DateTimeField(verbose_name=_("修改日期"), auto_now=True)

### 问题解决： ###
