Django i18n提供不完整的翻译

Question

我正面临着django翻译的问题。服务器运行时，我的.po文件的某些字符串不会出现。我的意思是一些翻译被显示，而其他翻译则没有。无论它们是否出现，它们都列在django.po文件中。这不是“模糊”标签的问题，因为我删除了它们。在很长的msgid或msgstr之后，这似乎不是空引号的问题。翻译显示错误的唯一原因是format_html（）函数，它允许输入更长的帮助文本。你对我如何解决这个案子有什么想法吗？

Answer 1

正如我所预期的那样，问题来自format_html()函数和懒惰翻译的需要。 ugettext_lazy()函数不适用于format_html()。它需要一个format_html_lazy()

核心/ utils.py

from django.utils.functional import lazy
from django.utils.html import format_html

format_html_lazy = lazy(format_html, str)

我在forms.py和models.py中更改了format_html()的调用

forms.朋友

from core.utils import format_html_lazy as format_html

而且你在那里！
