How to set userkey_id with @setter and token in django?
问题
Views.py
class CreatePost(generics.CreateAPIView):
serializer_class = PostSerializer
permission_classes = [permissions.IsAuthenticated]
def perform_create(self, serializer):
serializer.save(userkey=self.request.user)
Post model.py
from django.db import models
from accounts.models import CustomUser
class Post(models.Model):
# Foreign key
userkey = models.ForeignKey(CustomUser, on_delete=models.CASCADE)
# Properties
title = models.CharField(max_length=100, blank=True)
image = models.FileField(upload_to='files/', null=True, verbose_name="", blank=True)
price = models.IntegerField(default=0, blank=True)
description = models.TextField(blank=True)
likes = models.IntegerField(default=0)
tags = models.CharField(max_length=30, blank=True, default="tag1,tag2,...") # SQLite doesn't support arrays
date_modified = models.DateTimeField(auto_now=True, blank=True)
created = models.DateTimeField(auto_now_add=True, blank=True)
sold = models.BooleanField(default=False, blank=True)
@property
def user(self):
return self.userkey.username
@user.setter
def user(self, custom_user):
self.userkey = custom_user
@property
def datejoined(self):
return self.userkey.date_joined
def __str__(self):
return self.title
上述是代码的翻译，已经修正了@user.setter的问题，它接受一个custom_user参数，并将userkey设置为传入的用户对象。这应该解决你在客户端前端创建帖子时遇到的问题。希望这对你有所帮助。

I have created a client frontend and have tested the url using cUrl and it works, sending the auth token via axios headers allows me in to call the api. The problem is that I get a NOT NULL constraint failed: post_post.userkey_id error and have narrowed it down that the @user.setter is not getting the CustomUser from the Auth Token. How can I correctly use the @user.setter to set the user that has the corresponding auth token/created the post from the client frontend.
Views.py
class CreatePost(generics.CreateAPIView):
serializer_class = PostSerializer
permission_classes = [permissions.IsAuthenticated]
def perform_create(self,serializer):
serializer.save(user = self.request.user)
Post model.py
from django.db import models
from accounts.models import CustomUser
class Post(models.Model):
#foriegn keys
userkey = models.ForeignKey(CustomUser, on_delete=models.CASCADE)
#properties
title = models.CharField(max_length=100,blank=True)
image= models.FileField(upload_to='files/', null=True, verbose_name="",blank=True) #image field
price = models.IntegerField(default=0,blank=True)
description = models.TextField(blank=True)
likes = models.IntegerField(default=0)
tags = models.CharField(max_length=30,blank=True,default="tag1,tag2,...") #sqlite doesnt support arrays
date_modified = models.DateTimeField(auto_now=True,blank=True)
created = models.DateTimeField(auto_now_add=True,blank=True)
sold = models.BooleanField(default=False,blank=True)
@property
def user(self):
return self.userkey.username
@user.setter
def user(self):
return models.ForeignKey(CustomUser,on_delete=models.CASCADE)
@property
def datejoined(self):
return self.userkey.date_joined
def __str__(self):
return self.title
The userkey is to get data from the user thus I have a @property def user function to collect data from another object. The userkey and @property def user work fine from the admin panel. The @user.setter is used in order to allow the user to be changed from the views.py otherwise I get a "cannot change attribute 'user'" error. Thus I know that the problem is specifically from the @user.setter, I just don't know what I am doing wrong, everything seems fine. Post creation only seems to work from the Admin panel.

已修复，错误在 views.py 中：
class CreatePost(generics.CreateAPIView):
serializer_class = PostSerializer
permission_classes = [permissions.IsAuthenticated]
def perform_create(self, serializer):
serializer.save(userkey=self.request.user)
应该更改 'userkey' 而不是 'user'。
同时删除了 user.setter。我试图更改用户，但应该更改用户键，因为那是字段，而用户是一个属性。
英文:
Fixed, the error was in the views.py
class CreatePost(generics.CreateAPIView):
serializer_class = PostSerializer
permission_classes = [permissions.IsAuthenticated]
def perform_create(self,serializer):
serializer.save(userkey = self.request.user)
Should be changing the 'userkey' not the 'user'.
Also removed the user.setter. I was trying to change the user but it should have been the userkey as that is the field and user is a property.
