Question

如果我使用SQL语句在下拉列表中填充数据，则会收到此错误消息。

错误消息

'RawQuerySet' object has no attribute 'all'

Answer 1

正如第一条评论所说，您似乎在查询集上调用all（）。如果要将其分配给变量，则不必在执行原始sql查询后调用.all（），因为该变量已包含查询提取的所有对象。

In [6]: t = Team.objects.raw('SELECT * FROM core_team')

In [7]: t
Out[7]: <RawQuerySet: SELECT * FROM core_team>

In [8]: t[0]
Out[8]: <Team: test>
In [9]: [x for x in t ]
Out[9]: [<Team: test>, <Team: team2>, <Team: adminTeam>, <Team: team4>]

如果你打电话给t.all（）

In [11]: t.all()
    ---------------------------------------------------------------------------
    AttributeError                            Traceback (most recent call last)
    <ipython-input-11-2ce0015f044f> in <module>()
    ----> 1 t.all()

    AttributeError: 'RawQuerySet' object has no attribute 'all'

    In [12]:

因此，在执行sql raw查询后，您似乎正在调用all()。删除那段代码，它将被解决。如果您想使用更好的方法来执行SQL查询，可以参考to this section of django docs。

修改

尝试将form.fields["set_auto_reply_for_fan_page"].query更改为form.fields["set_auto_reply_for_fan_page"].queryset

Answer 2

您可以在sql中创建视图或选择查询然后您可以使用原始sql操作此查询例如，您想使过滤器具有类似竞争性。第一个选择带有视图的所有联接表或选择查询是第一个查询新查询是原始处理的查询。不是：为postgressql选择语法

|> aggregateWindow(every: 15m, fn: count)

Answer 3

form.fields["set_auto_reply_for_fan_page"].choices = [(None, '---'),] + [ (x.id, x.name ,) for x in FacebookFanPage.objects.raw('''select id, name from dual''')]

Django错误'RawQuerySet'对象没有属性'all'
