Question

我正在使用Django 2.2，MySQL 8.0。定义模型时，我会创建一些类属性及其字段。保存操作后，PyCharm未报告错误。

from django.db import models
from django_mysql.models import JSONField
class Activity(models.Model):
    sponsor               = models.IntegerField
    certificateOrNot      = models.BooleanField
    sponsorWay            = models.SmallIntegerField
    activityName          = models.CharField(max_length=60)
    activityPhoto         = models.URLField(max_length=255)
    prizeInfo             = JsonField
    activityDetails       = models.IntegerField
    startTime             = models.DateField
    endTime               = models.DateField
    conditionType         = models.SmallIntegerField
    conditionInfo         = models.SmallIntegerField
    sponsorPhoneNumber    = models.CharField(max_length=20)
    sponsorNickName       = models.CharField(max_length=40)
    sponsorWechatNumber   = models.CharField(max_length=255)
    participantAttention  = models.BooleanField
    shareJurisdiction     = models.BooleanField
    allowQuitOrNot        = models.BooleanField
    inviateFriends        = models.BooleanField
    inputCommandOrNot     = models.BooleanField
    participateWay        = models.BooleanField
    winnerList            = models.BooleanField
    participantDrawNumber = models.SmallIntegerField

def __str__(self):
    return self.activityName

然后我同步数据库。

python3 manage.py makemigrations luckyDraw_1
python3 manage.py migrate

这时MySQL可以成功创建表，但是表中的字段不符合我的期望。

+---------------------+--------------+------+-----+---------+----------------+
| Field               | Type         | Null | Key | Default | Extra          |
+---------------------+--------------+------+-----+---------+----------------+
| id                  | int(11)      | NO   | PRI | NULL    | auto_increment |
| activityName        | varchar(60)  | NO   |     | NULL    |                |
| activityPhoto       | varchar(255) | NO   |     | NULL    |                |
| sponsorPhoneNumber  | varchar(20)  | NO   |     | NULL    |                |
| sponsorNickName     | varchar(40)  | NO   |     | NULL    |                |
| sponsorWechatNumber | varchar(255) | NO   |     | NULL    |                |
+---------------------+--------------+------+-----+---------+----------------+

那么，怎么了？

Answer 1

数据库表中缺少某些字段，因为最后缺少某些字段中的括号，例如，第一个字段应为sponsor = models.IntegerField()而不是sponsor = models.IntegerField

Django定义了一个模型，但是该模型的某个字段不起作用
