我有两个模型类用户和帐户一起链接或由另一个名为useraccounts的表连接。
我想要的是,当我向他们提交数据(用户和帐户)时,useraccounts表也会自动填充用户和帐户表的ID。
class Account(models.Model):
# fields
id = models.IntegerField(primary_key=True)
t_stamp = models.DateField(default=datetime.datetime.now())
acctno = models.TextField(null=False, unique =True)
acctname = models.TextField(null=False)
status = models.TextField(null=False, choices=STATUS)
accttype = models.TextField(null=False,choices=ACCT_TYPE)
acctclass = models.TextField(null=False, choices=ACCT_CLASS)
min_balance = models.FloatField(default=0)
cur_balance = models.FloatField(default=0)
ava_balance = models.FloatField(default=0)
#fundingsources = models.ManyToManyField(FundingSource)
class Meta:
managed = False
db_table = 'accounts'
def save(self, *args, **kwargs):
super(Account, self).save(*args, **kwargs)
try:
self.useraccount_set.all()[0]
except:
UserAccount.objects.bulk_create([UserAccount(account_id=self,user_id=user) for user in User.objects.all()])
class User(AbstractBaseUser, PermissionsMixin):
id = models.AutoField(primary_key=True)
username = models.TextField(unique=True, null=True)
fullname = models.TextField(null=False)
country = models.TextField(null=True)
email = models.EmailField( unique=True, db_index=True)
phone = models.TextField()
address = models.TextField()
activation_key = models.CharField(max_length=40)
key_expires = models.DateTimeField(null=True)
date_joined = models.DateTimeField(default=timezone.now)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=True)
#accounts = models.ManyToManyField(Account, through='UserAccount')
class Meta:
db_table = "users"
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['username']
objects = UserManager()
def get_short_name(self):
return self.fullname
def get_username(self):
return self.email
def is_authenticated(self):
return True
@property
def is_staff(self):
"Is the user a member of staff?"
# Simplest possible answer: All admins are staff
return self.is_admin
signals.post_save.connect(create_auth_client, sender=User)
User._meta.get_field_by_name('email')[0]._unique=True
class UserAccount(models.Model):
user_id = models.ForeignKey(User)
account_id = models.ForeignKey(Account)
class Meta:
managed = False
db_table = 'useraccounts'
class UserAccount(models.Model):
user_id = models.ForeignKey(User)
account_id = models.ForeignKey(Account)
class Meta:
managed = False
db_table = 'useraccounts'

您必须在模型保存方法中执行此操作:
class Account(models.Model):
id = models.IntegerField(primary_key=True)
def save(self, *args, **kwargs):
super(Account, self).save(*args, **kwargs)
try:
self.useraccount_set.all()[0]
except:
UserAccount.objects.bulk_create([UserAccount(account_id=self,user_id=user) for user in User.objects.all()])
class User(AbstractBaseUser, PermissionsMixin):
id = models.AutoField(primary_key=True)
def save(self, *args, **kwargs):
super(User, self).save(*args, **kwargs)
try:
self.useraccount_set.all()[0]
except:
UserAccount.objects.bulk_create([UserAccount(user_id=self,account_id=account) for account in Account.objects.all()])
