python - 如何使用 django-cms Python api 创建页面？

Question

我正在尝试编写一个 CMS 内容迁移脚本，该脚本将为 django-cms 创建页面。然而，即使默认安装 Django-cms，Django-treebeard 仍然会引发异常，我不清楚为什么。

例如，当执行此行时:

api.create_page(title="Hello world",
    language='en',
    parent=None)

我的脚本总是在来自treebeard的mp_tree.py(v 4.1.0)中失败(第307-8行):

if newobj.pk:
    raise NodeAlreadySaved("Attempted to add a tree node that is "\
                "already in the database")

有人有一个关于如何使用 cms.api.create_page() 方法的非常简单的示例吗？

Answer 1

感谢 @dentemm 和 @paulo，我能够在 Python shell 中运行它，如下所示:

>>> from cms import constants
>>> from cms.constants import TEMPLATE_INHERITANCE_MAGIC
>>> from cms import api
>>> api.create_page(title="Hello World4",language='en',template=TEMPLATE_INHERITANCE_MAGIC,parent=None)

<cms.models.pagemodel.Page object at 0x102b674e0>

它失败了，因为我没有包含"template"参数和必要的导入。
