django 1.7迁移不更新数据库

Question

我运行了python manage.py makemigrations core，它在/ opt / project / core / migrations中创建了以下文件

0001_initial.py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import models, migrations
from django.conf import settings


class Migration(migrations.Migration):

    dependencies = [
        migrations.swappable_dependency(settings.AUTH_USER_MODEL),
    ]

    operations = [
        migrations.CreateModel(
            name='Customer',
            fields=[
                ('id', models.AutoField(verbose_name='ID', serialize=False, auto_created=True, primary_key=True)),
                ('company', models.CharField(max_length=100)),
                ('department', models.CharField(max_length=100)),
                ('user', models.OneToOneField(to=settings.AUTH_USER_MODEL)),
            ],
            options={
            },
            bases=(models.Model,),
        ),
    ]

然后我运行python manage.py migrate并且它什么也没做。它不是在数据库中创建表。

运行python manage.py sqlmigrate core不会返回任何内容。

我使用postgres作为我的后端数据库db1，架构是core。
