我有一个 django 项目，我在其中使用 django-rest-auth 对用户进行身份验证。我的设置.py：

INSTALLED_APPS = (
 'django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'django.contrib.sites',
 'rest_framework',
 #following was added to allow cross domain requests
 'corsheaders',
 #following were added for ssl thing
 'djangosecure',
 'sslserver',
 #following were added for authentication
 'rest_framework.authtoken',
 'rest_auth',
 'allauth',
 'allauth.account',
 'rest_auth.registration',
 'demo',
)

我有两个模型：运动和评级。我没有创建用户模型，因为它必须由 django-rest-auth / django.contrib.auth 提供。用户可以对特定练习给出多个评级。

我的 models.py 如下所示：

class Exercise(models.Model):

#Field for storing exercise type
EXERCISE_TYPE_CHOICES = (
    (1, 'Best stretch'),
    (2, 'Butterfly reverse'),
    (3, 'Squat row'),
    (4, 'Plank'),
    (5, 'Push up'),
    (6, 'Side plank'),
    (7, 'Squat'),
)
exercise_type = models.IntegerField(choices=EXERCISE_TYPE_CHOICES)

#Field for storing intensity level
INTENSITY_LEVEL_CHOICES = (
    (1, 'Really simple'),
    (2, 'Rather Simple'),
    (3, 'Simple'),
    (4, 'Okay'),
    (5, 'Difficult'),
    (6, 'Rather Difficult'),
    (7, 'Really Difficult'),
)

intensity_level = models.IntegerField(choices=INTENSITY_LEVEL_CHOICES)
#Field for storing video url for a particular exercise
video_url = models.URLField()
#Field for storing description of the exercise
description = models.CharField(max_length=500)


class Rating(models.Model):

#Field for storing exercise type
exercise = models.ForeignKey(Exercise, related_name='ratings', blank=True, null=True)
#Field for storing rating
RATING_CHOICES = (
    ('H', 'Happy'),
    ('N', 'Neutral'),
    ('S', 'Sad'),
)
value = models.CharField(max_length=1,choices=RATING_CHOICES)

根据上面的描述，我的Rating模型还应该包含userid作为外键以及exerciseid，对吧？

我怎样才能做到这一点？如何修改我的评分模型？我需要导入什么？

from django.contrib.auth.models import User

class Rating(models.Model):
    user = models.ForeignKey(User)
    # other fields

我想这就是你要找的。 这是我认为与您的问题有关的示例
