如何更改 Wagtail 的默认语言？

Question

我正在使用 headless Wagtail 并想将默认后端语言更改为葡萄牙语 (pt-pt)。 正在关注 wagtail's docs：

# settings.py

USE_I18N = True

LANGUAGE_CODE = "pt-pt"

那么为什么我尝试发布一个 wagtail 页面时出现以下错误：

有什么建议吗？我还缺少一些额外的步骤吗？

您正在关注 Wagtail 2.0 的文档，该文档已经过时了。 Wagtail 2.11 的国际化支持文档（在撰写本文时尚未发布）可在此处找到：https://docs.wagtail.io/en/latest/advanced_topics/i18n.html

As mentioned there，当您在设置文件中配置语言时，您还需要在数据库中设置区域设置记录。这可以在数据迁移中完成，或者通过启用 wagtail.locales 应用程序并通过管理中的设置 -> 区域设置来完成：

INSTALLED_APPS = [
    # ...
    'wagtail.locales',
    # ...
]
