输入命令：

在编写models之前，先声明utf-8编码：

# _*_ encoding:utf-8 _*_

# _*_ encoding:utf-8 _*_
from __future__ import unicode_literals

from datetime import datetime  # python自带的

from django.db import models  # django的

from users.models import UserProfile
from courses.models import Course

# Create your models here.


class UserAsk(models.Model):
    name = models.CharField(max_length=20, verbose_name=u"姓名")
    mobile = models.CharField(max_length=11, verbose_name=u"手机")
    course_name = models.CharField(max_length=50, verbose_name=u"课程名")
    add_time = models.DateTimeField(default=datetime.now ,verbose_name=u"添加时间")

    class Meta:
        verbose_name = u"用户咨询"
        verbose_name_plural = verbose_name


class CourseComments(models.Model):
    "课程评论"
    user = models.ForeignKey(UserProfile, verbose_name=u"用户")
    course = models.ForeignKey(Course, verbose_name=u"课程")
    comments = models.CharField(max_length=200, verbose_name=u"评论")
    add_time = models.DateTimeField(default=datetime.now ,verbose_name=u"添加时间")

    class Meta:
        verbose_name = u"课程评论"
        verbose_name_plural = verbose_name


class UserFavorite(models.Model):
    user = models.ForeignKey(UserProfile, verbose_name=u"用户")
    fav_id = models.IntegerField(default=0, verbose_name=u"数据id")
    fav_type = models.IntegerField(choices=((1, "课程"),(2, "课程机构"),(3, "讲师")), default=1, verbose_name=u"收藏类型")
