我有以下预先存在的数据库表,其中包含id和id以及描述。我必须在我的User表之前加载它才能正确关联ForeignKey。
class QVDSSSecurityDimension(models.Model):
coid = models.CharField(db_column='CM_Data_Restriction', serialize=False, max_length=10, primary_key = True) # Field name made lowercase.
coid_name = models.CharField(db_column='CM_Company_Name', max_length=50, blank=True, null=True) # Field name made lowercase.
class Meta:
managed = False
db_table = 'QV_DSS_Security_Dimension'
我的自定义用户模型基于以下内容构建:
class User(AbstractBaseUser, PermissionsMixin):
email = models.EmailField(unique=True)
username = models.CharField(max_length=7, unique=True)
formattedusername = models.CharField(max_length=11, unique=True, primary_key = True)
first_name = models.CharField(max_length=40)
last_name = models.CharField(max_length=140)
date_joined = models.DateTimeField(default=timezone.now)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
is_cfo = models.BooleanField(default=False)
facility = models.CharField(max_length=140)
officename = models.CharField(max_length=100)
jobdescription = models.CharField(max_length=140)
positioncode = models.CharField(max_length = 100)
positiondescription = models.CharField(max_length=140)
coid = models.ForeignKey(QVDSSSecurityDimension, null=True, blank = True, db_constraint=False)
streetaddress = models.CharField(max_length=140)
title = models.CharField(max_length=100)
USERNAME_FIELD = 'username'
class Meta:
app_label = 'accounts'
db_table = "user"
def save(self, *args, **kwargs):
self.formattedusername = '{domain}\{username}'.format(
domain='HCA', username=self.username)
super(User, self).save(*args, **kwargs);
def get_short_name(self):
return self.username
# REQUIRED_FIELDS = "username"
def __str__(self):
return '%s - %s %s' % (self.username, self.first_name, self.last_name)
所有内容都适用于makemigrations并进行迁移,但如果数据库中不存在User.coid,则在尝试登录时会出现以下错误:
ValueError: Cannot assign "'08732'": "User.coid" must be a "QVDSSSecurityDimension" instance.
我确认QID确实存在于QVDSSSecurityDimension中,但由于表中没有带有coid的用户,因此它会抛出该错误。如果用户使用AD验证并且自定义用户表中不存在其coid,如何使登录仍能正常运行?
我尝试使用db_constraint = True时Null = True和Blank = True,似乎没有任何效果。用户存储到数据库后,coid将存在,但此错误发生在此之前。

我可以从没有DSSSecurityDimension的我的formattedusername获取coid,因为它从AD中提取它,但是我需要来自DSSSecurityDimension的描述,这就是我在配置文件模板上引入coid的原因,但是来自User.coid不是DSSSecurityDimension.coid。
我的模板中的Coid使用以下li
进行渲染<li>Coid: {{ user.coid }}</li>
代码行在python库中,而不是我的视图,这告诉我它的模型存在问题:

答案 0 :(得分:1)
我想我看到了问题。您希望User
的{{1}}字段包含相关coid
对象的实际ID,但这不是QVDSSSecurityDimension
默认情况下的工作方式。
ForeignKey
的{{1}}字段实际上是仅存在于Python逻辑中的属性。在数据库级别,User
表中没有coid
列。这是因为Django创建了另一个未在模型中显式声明的字段,名为coid
,用于保存相关对象的ID。 那是数据库中实际存在的列和值。
换句话说,如果列出User
对象的属性,您会看到它有两个字段:coid_id
和User
。 coid
将检索coid_id
的实例,而coid
将保留您尝试设置的实际值。
检查Django's documentation。 This post还可以帮助您了解QVDSSSecurityDimension
和coid_id
的工作方式。
这是我认为您正在寻找的:
coid
我将coid_id
重命名为class User(AbstractBaseUser, PermissionsMixin):
...
co = models.ForeignKey(QVDSSSecurityDimension, null=True, blank=True)
...
以使其更直观,因为它不会保留实际ID。我还删除了coid
,因为默认co
应该可以正常工作。
当您尝试将db_constraint=False
设置为您的用户时,您可以执行以下操作:
db_constraint=True
或:
QVDSSSecurityDimension
或:
some_user = User.objects.first()
some_dimension = QVDSSSecurityDimension.objects.get(coid='08732')
some_user.co = some_dimension
some_user.save()
看到区别?我希望这有助于澄清一些事情。 :)
修改强>
具体来说,问题出在设置变量some_user = User.objects.first()
some_dimension = QVDSSSecurityDimension.objects.get(coid='08732')
some_user.co_id = some_dimension.coid
some_user.save()
中,它试图将some_user = User.objects.first()
some_dimension_id = '08732'
some_user.co_id = some_dimension_id
some_user.save()
内的ID(从LDAP_AUTH_USER_FIELDS
收到的数据)映射到extensionAttribute10
&# 39; s LDAP
字段,它预期User
个实例。解决方案是将coid
中的密钥从QVDSSSecurityDimension
更改为LDAP_AUTH_USER_FIELDS
。
