__init__() got an unexpected keyword argument 'hints'
Request Method: GET
Request URL:    http://localhost/
Django Version: 1.7.4
Exception Type: TypeError

class Tier(models.Model):
    id = models.IntegerField(primary_key=True)
    name = models.CharField(max_length=100)

class Recipe(models.Model):
    id = models.UUIDField(auto_add=True, primary_key=True, default=uuid.uuid4)
    name = models.CharField(max_length=100)

EDIT: I ended up just saying screw it and converted my project over to mysql and everything works fine. If someone comes up with an valid answer I will test it on a new formed project and mark it as correct.

编辑:最后我只是说，把我的项目转换成mysql，一切都很好。如果有人提出一个有效的答案，我会在一个新形成的项目上测试它，并把它标记为正确。

Install the latest version of django-pgfields from git. It fixed it for me.

从git安装django-pgfields的最新版本。它帮我修好了。

If you install from requirements file then remove 'django-pgfields' and add

如果从需求文件安装，则删除“django-pgfields”并添加
