之前我创建了两个字段并迁移了所有内容.之后,我试图添加三个字段title,about,birthdate到模型中.我创建了一个这样的模型:

from __future__ import unicode_literals
from django.utils import timezone
from django.db import models

# Create your models here.

class APP1Model(models.Model):
    name = models.CharField(max_length=120)
    percentage = models.CharField(max_length=120)
    title = models.CharField(max_length=100,default='Title')
    birth_date = models.DateTimeField(blank=True, null=True)
    about = models.TextField(max_length=100,null=True,default='About Yourself')

    def __unicode__(self):
        return self.name

但是当我尝试在python shell中迁移时,它会显示如下的验证错误:

我想卸载Odoo 9并在我的linux系统中重新安装.谁能帮帮我吗？
