关于python：与postgres的Django 1.8迁移错误

Django 1.8 migration error with postgres

我是Django的新手，我正在尝试使用Django(1.8)在Postgre中创建表

以下是我的模型类

class Student(models.Model):
name = models.CharField(max_length = 50)
degree = models.CharField(max_length = 50)
numofsubs = models.IntegerField()
namesofsubs= models.CharField(max_length = 50)
details = models.CharField(max_length = 50)

class Meta:

db_table ="student"

views.py

def addStudent(request):
student = Student(name = request.name, degree = request.degree ,
numofsubs = request.numofsubs , nameofsubs = request.nameofparams , details = request.details)
student.save()
print 'data saved'

在我尝试运行python manage.py migrate之后发生这些更改后，我得到了django.db.utils.ProgrammingError: permission denied for relation django_migrations

以下是堆栈跟踪

请指导我的应用程序有什么问题。

谢谢
