我在Django应用程序上使用登录时遇到问题。我创建了一个自定义用户模型，它可以很好地与数据库配合使用。有些登录页面不起作用，它需要Json数据。我不知道它为什么这么做。我有以下型号的
class AdminAccounts(BaseUserManager):
def create_user(self, user, password=None):
"""
Creates and saves a User with the given email and password.
"""
if not user:
raise ValueError('Users must have an email address')
user = self.model(
email=self.normalize_email(user),
)
user.set_password(password)
user.save(using=self._db)
return user
def create_staffuser(self, user, password):
"""
Creates and saves a staff user with the given email and password.
"""
user = self.create_user(
user,
password=password,
)
user.staff = True
user.save(using=self._db)
return user
def create_superuser(self, user, password):
"""
Creates and saves a superuser with the given email and password.
"""
user = self.create_user(
user,
password=password,
)
user.staff = True
user.admin = True
user.save(using=self._db)
return user
class User(AbstractBaseUser):
id = models.BigAutoField(primary_key=True)
user = models.CharField(max_length=50,unique=True,verbose_name='User name')
name = models.CharField(max_length=50,verbose_name='User name',default=None,blank=True, null=True)
email = models.EmailField(
verbose_name='email address',
max_length=255,
unique=True,
)
is_active = models.BooleanField(default=True)
staff = models.BooleanField(default=False) # a admin user; non super-user
admin = models.BooleanField(default=False) # a superuser
objects= AdminAccounts()
# notice the absence of a "Password field", that is built in.
USERNAME_FIELD = 'user'
REQUIRED_FIELDS = [] # Email & Password are required by default.
class Meta:
managed = True
db_table = 'adminaccounts'
verbose_name_plural ="Admin Accounts"
def get_full_name(self):
# The user is identified by their email address
return self.name
def get_short_name(self):
# The user is identified by their email address
return self.user
def __str__(self):
return self.user
def has_perm(self, perm, obj=None):
"Does the user have a specific permission?"
# Simplest possible answer: Yes, always
return True
def has_module_perms(self, app_label):
"Does the user have permissions to view the app `app_label`?"
# Simplest possible answer: Yes, always
return True
@property
def is_staff(self):
"Is the user a member of staff?"
return self.staff
@property
def is_admin(self):
"Is the user a admin member?"
return self.admin
def __unicode__(self):
return self.get_full_name()
以下登录视图
class LoginForm(forms.Form):
user=forms.CharField(max_length=6)
password=forms.CharField(max_length=128)
def clean(self):
self.cleaned_data = super().clean()
#print(self.cleaned_data)
return self.cleaned_data
def dologin(request):
next = ""
if request.GET:
next = request.GET['next']
if request.method == 'POST':
form = LoginForm(request.POST)
if form.is_valid():
username = form.cleaned_data['user']
password = form.cleaned_data['password']
user = authenticate(request,username=username, password=password)
if user is not None and user.is_active:
login(request, user)
request.session.create()
request.session['user']=user
request.session.set_expiry(900)
if next == "":
return redirect(dashboard)
else:
return HttpResponseRedirect(next)
else:
return render(request, 'index.html', {'invalid_authentication': True})
else:
return render(request, 'index.html', {'invalid_authentication': True})
else:
return render(request, 'index.html', {'invalid_authentication': False})
我在使用登录时收到以下错误
raise TypeError(f'Object of type {o.__class__.__name__} '
TypeError: Object of type User is not JSON serializable
[22/Dec/2021 09:51:47] "POST /dologin/ HTTP/1.1" 500 104786
如果我删除登录(请求、用户(代码，它就可以正常工作。我不知道我错过了什么。有人能帮我吗？
很抱歉这是一个拼写错误，在CCD_ 1。
它必须如下
request.session['user']=username
