Question

我已经定义了UserDetail模型，它与User有一对一的关系。

>>> from xlwings import Workbook, Sheet, Range, Chart
>>> wb = Workbook()
>>> Sheet(1).name
u'Sheet1'
>>> Range('A1').value = 'Foo 1'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/xlwings/main.py", line 622, in __init__
    self.row2 = self.row1 + xlplatform.count_rows(self.xl_sheet, range_address) - 1
  File "/Library/Python/2.7/site-packages/xlwings/_xlmac.py", line 145, in count_rows
    return xl_sheet.cells[range_address].count(each=kw.row)
  File "/Library/Python/2.7/site-packages/aeosa/appscript/reference.py", line 431, in __call__
    raise TypeError('Unknown keyword argument %r.' % name)
TypeError: Unknown keyword argument 'each'.

但是当我在我的视图中通过request.user尝试访问UserDetail对象时，它会引发错误，因为“用户没有用户详细信息。”。

class UserDetail(models.Model):
    user = models.OneToOneField(User)
    ....

虽然我能够在Django shell中使用 user.userdetail 。我不知道它为什么会发生，请求.user与User对象有什么不同吗？

Answer 1

没有。这是因为该特定用户没有关联的UserDetail实例。

request.user和实际的User对象有区别吗？
