Django編程錯誤關係不存在

Question

在我的應用程序中，一切似乎都能順利運行，直到我嘗試從管理站點訪問這些模型時，那就是當我收到我提到的錯誤時，我安裝了Allauth並已做好了所有必要的準備遷移，但無論我做什麼，我都會收到同樣的錯誤。

任何想法？

下面是型號：

class Cuentas(models.Model): 
    idCuenta = models.AutoField(primary_key=True, null=False, max_length=15) 
    user = models.OneToOneField(User) 
    Saldo = models.CharField(max_length=50) 

    class Meta: 
     managed = False 
     db_table = 'cuentas' 

class Depositos(models.Model): 
    idDeposito = models.AutoField(primary_key=True, null=False, max_length=15) 
    idCuenta = models.ForeignKey(Cuentas) 
    Tipo = models.CharField(max_length=200) 
    Monto = models.CharField(max_length=50) 
    Fecha = models.DateField() 

    class Meta: 
     managed = False 
     db_table = 'deposits'

Exception Type: ProgrammingError at /admin/DraftFantasy/cuentas/ 
Exception Value: relation "cuentas" does not exist 
LINE 1: SELECT COUNT(*) FROM "cuentas" 

這是最初的移民在其內部產生兩種型號

class Migration(migrations.Migration): 

dependencies = [ 
    migrations.swappable_dependency(settings.AUTH_USER_MODEL), 
] 

operations = [ 
    migrations.CreateModel(
     name='Cuentas', 
     fields=[ 
      ('idCuenta', models.AutoField(max_length=15, serialize=False, primary_key=True)), 
      ('Saldo', models.CharField(max_length=50)), 
      ('user', models.OneToOneField(to=settings.AUTH_USER_MODEL)), 
     ], 
     options={ 
     }, 
     bases=(models.Model,), 
    ), 
    migrations.CreateModel(
     name='Depositos', 
     fields=[ 
      ('idDeposito', models.AutoField(max_length=15, serialize=False, primary_key=True)), 
      ('Tipo', models.CharField(max_length=200)), 
      ('Monto', models.CharField(max_length=50)), 
      ('Fecha', models.DateField()), 
      ('idCuenta', models.ForeignKey(to='DraftFantasy.Cuentas')), 
     ], 
     options={ 
     }, 
     bases=(models.Model,), 
    ), 

感謝代碼！

我不確定，不管這是否是同一個問題，但我只是通過捕獲這個ProgrammingError異常來修復我自己的類似問題 - 看看here。

從我從調查中得知的情況來看，在第一次運行python manage.py migrate之前，似乎從admin.py的配置已加載。這在開發過程中可能會非常棘手，因爲如果您首先創建模型，然後在本地進行遷移並稍後在取決於新模型的admin.py中進行一些更改，則無法注意到此問題。

因此請確保您的admin.py文件不依賴於型號，或者在遷移數據庫之前首先運行。
