django models建立问题

Question

1.系统环境：python2.7.3 django 1.10.3 ubutu12.04 mysql 5.5.3 2.问题：在使用django的models建立表， 1)models内容： class Test(models.Model): name = models.CharField(max_length=20) score = models.IntegerField(default=0) date = models.DateField() def __unicode__(self): return u'%s %d %s' % (self.name,self.score,self.date) class User(models.Model): username = models.CharField(max_length=20) passwd = models.CharField(max_length=20) def __unicode__(self): return u'%s %s' % (self.name,self.passwd) class info(models.Model): address= models.CharField(max_length=20) phone = models.CharField(max_length=20) def __unicode__(self): return u'%s %s' % (self.address,self.phone) 2)执行建表语句后回显： root@precise32:/usr/local/frist_django# python manage.py makemigrations Migrations for 'testdb': testdb/migrations/0001_initial.py: - Create model info - Create model Test - Create model User 3）此时数据库中应该有这三张表，但是数据库中只有第一个表 mysql> show tables; Tables_in_django testdb_test 4）但是在初始化文件中也是有三张表的建立语句。 class Migration(migrations.Migration): initial = True dependencies = [ ] operations = [ migrations.CreateModel( name='info', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('address', models.CharField(max_length=20)), ('phone', models.CharField(max_length=20)), ], ), migrations.CreateModel( name='Test', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('name', models.CharField(max_length=20)), ('score', models.IntegerField(default=0)), ('date', models.DateField()), ], ), migrations.CreateModel( name='User', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('username', models.CharField(max_length=20)), ('passwd', models.CharField(max_length=20)), ], ), ] 新看django，这是怎么回事，为什么只有一个表被建了呢？求大神解释一下。
