Django插入Oracle數據庫無效標識符

試圖用Django將數據插入到我的數據庫表中。這是我的表我想插入模式：Django插入Oracle數據庫無效標識符

class RunableFilters(models.Model): 
    equipment_id = models.BigIntegerField(null=True, blank=True) 
    filter_file_name = models.CharField(max_length=255, blank=True) 
    last_updated = models.CharField(max_length=255, blank=True) 
    class Meta: 
     db_table = 'runable_filters'

錯誤，我得到：

>>> from books.models import RunableFilters 
>>> p1 = RunableFilters(equipment_id = '123456778', filter_file_name = "test_file_name", last_updated = "2013-16-8") 
>>> p1.save()

運行32位的Python 2.7和Django的1.5.2 – shreddish

是DB通過Django的創建'syncdb'命令？如果沒有，請向我們展示您的表格架構。 –

該數據庫是一個遺留的數據庫，並創建和結構與RunableFilters表一樣，我運行inspectdb創建該表的模型..添加表 – shreddish

也就是說問題，django期望一個名爲id

Y你可以輕鬆解決它，瞭解整合遺留數據庫：https://docs.djangoproject.com/en/dev/howto/legacy-databases/。

對於您的代碼，找到主鍵並通知django它。 Le'ts supose equipment_id可以爲PK作用：

class RunableFilters(models.Model): 
    equipment_id = models.BigIntegerField(primary_key=True) #<-- here 
    filter_file_name = models.CharField(max_length=255, ...

如果你有複合PK的話，看到這篇文章：https://code.djangoproject.com/wiki/MultipleColumnPrimaryKeys

從字面上看，只是嘗試添加equipment_id作爲主鍵，它在我檢查之前正常工作。即將寫出一個答案。感謝您的幫助 – shreddish
