迁移Django的1.11

为什么当我试图转移我的模型，每部分型号，我补充说，尽管一些错误，如：迁移Django的1.11

我不想删除并创建另一个数据库。我只想改变现有的数据库，如果我的数据库中有一些数据？

(1060, "Duplicate column name ...) 
(1054, "Unknown column 'vacina_agentmodel.phone' in 'field list'") 
(1054, "Unknown column 'created' in 'vacina_vaccinemodel'")

初始迁移

dependencies = [ 
    ('vacina', '0001_initial'), 
] 

operations = [ 
    migrations.CreateModel(
     name='PatientModel', 
     fields=[ 
      ('id', models.UUIDField(default=uuid.uuid4, editable=False, primary_key=True, serialize=False)), 
      ('complete_name', models.CharField(max_length=100, verbose_name='Nome completo')), 
      ('birthday', models.DateField(verbose_name='Data de nascimento')), 
      ('email', models.EmailField(default='', max_length=200, verbose_name='Email')), 
      ('phone', models.IntegerField(blank=True, verbose_name='Número de telefone')), 
      ('address', models.CharField(default='', max_length=200, verbose_name='Endereço')), 
      ('house_number', models.CharField(blank=True, max_length=10, verbose_name='Número da casa/apartamento')), 
      ('country', models.CharField(default='', max_length=100, verbose_name='Pais')), 
      ('province', models.CharField(default='', max_length=100, verbose_name='Estado')), 
      ('zip_code', models.IntegerField(verbose_name='CEP')), 
      ('created_at', models.DateTimeField(auto_now_add=True)), 
      ('last_modification', models.DateTimeField(auto_now=True)), 
     ], 
     options={ 
      'ordering': ('created_at',), 
     }, 
    ), 
]

有什么变化处理你的' models.py'和你正在使用哪个数据库？ – Gahan

你可以分享你的models.py文件 – viveksyngh

我会评论我的模特，py请在 –

嘿在你的应用程序文件夹中会有一个名为migrations的文件夹，尝试以001_initial.py格式删除所有文件，然后从命令提示符下运行makemigrations命令，这允许您在不删除整个数据库的情况下编辑模型。

编辑：嘿，请点击此链接：Currently using Django "Evolution", is "South" better and worth switching?尝试使用南也许这就是回答您的问题一次数据库已设置

以下，但这是临时解决方案，如果模型将被再次修改它将再次产生相同的错误 – Gahan

是的，文档说这不是一个好习惯，因为我们需要这些迁移来做一些回滚或类似的事情...... –

我的models.py
