Question

我在尝试从管理面板添加模型元素时使用django 2.0版获取完整性错误。虽然我可以从shell添加元素。

models.py

class Book(models.Model):
    name = models.CharField(max_length=30)

    def __str__(self):
        return self.name

admin.py

admin.site.register(Book)

我正在使用sqlite数据库

从管理面板添加时出现以下错误

Internal Server Error: /admin/accounts/book/add/
Traceback (most recent call last):
  File "/myproject/env/lib/python3.4/site-packages/django/db/backends/base/base.py", line 239, in _commit
    return self.connection.commit()
sqlite3.IntegrityError: FOREIGN KEY constraint failed

The above exception was the direct cause of the following exception:
