Django 中的 db_type（尝试使用 mysql 安装 pootle）

Question

在此处提出的类似查询：Getting db_type() error while using django-facebook connect for DjangoApp

我正在尝试在 CentOS 机器上安装 Pootle，并提供以下详细信息：

[root@localhost pootle]# cat /etc/redhat-release<br>
CentOS release 6.2 (Final)
<br>
[root@localhost pootle]# PootleServer --version<br>
Pootle 2.1.6<br>
Translate Toolkit 1.9.0<br>
Django 1.4<br>
[root@localhost pootle]# python -V<br>
Python 2.6.6

我收到以下错误：

Creating tables ...
Traceback (most recent call last):
  File "/usr/lib64/python2.6/wsgiref/handlers.py", line 94, in run
    self.finish_response()

    chunk = self._iterator.next()

    col_type = f.db_type(connection=self.connection)
TypeError: db_type() got an unexpected keyword argument 'connection'

在我将 /usr/lib/python2.6/site-packages/django/db/backends/creation.py 编辑为我认为可以纠正问题的方式后，我仍然得到当我尝试加载网页时，来自我的 PootleServer 屏幕的以下输出：

Creating tables ...

  File "/usr/lib/python2.6/site-packages/django/db/backends/creation.py", line 45, in sql_create_model
    col_type = f.db_type(self.connection)
TypeError: db_type() takes exactly 1 argument (2 given)

网页显示：

Error: "(1146, "Table 'p2.siteconfig_siteconfiguration' doesn't exist")" while attempting to access the Pootle database, will try to initialize database.

有问题的行是第 44 行，如下所示：

    col_type = f.db_type(connection=self.connection)

我已将其注释掉，并在其下方添加了一行，如下所示：

    #col_type = f.db_type(connection=self.connection)
    col_type = f.db_type(self.connection)

之前运行服务器呈现了这个错误，但是它之前有一些成功的创建通知，我们可以在这里看到：

很抱歉，如果这是一个冗长的问题，但我正在尝试提供尽可能多的相关信息，以便让您对正在发生的事情有一个很好的了解。

如果您知道解决此问题的方法，请告诉我，因为互联网似乎相当缺乏与 Pootle 相关的修复。

编辑： 看到了这个：How to fix django's db_type deprecation warning?

将 settings.py 文件更改为包含以下内容：

    col_type = f.db_type(connection=connection)
    #col_type = f.db_type(connection=self.connection)
    #col_type = f.db_type(self.connection)

收到此错误：

NameError: global name 'connection' is not defined

Answer 1

Pootle 似乎不支持 Django 1.4 卸载 Django 1.4 并安装较旧的 1.3.1 版本。
