复数形式表达可能是危险的 [英] plural forms expression could be dangerous

问题描述

我已经看过这个问题： Django ：gettext引发ValueError：'复数形式表达式可能是危险的'，而它可以帮助我理解它不能解决的问题。

I've looked at this question: Django: gettext raises ValueError: 'plural forms expression could be dangerous' and while it helps me understand the issue it doesn't solve it.

我有一个漂亮的香草 django-cms 安装，其中一个语言需要是波兰语，一个多于一个复数形式的语言。

I have a pretty vanilla django-cms install, and one of the languages needs to be Polish, a language with more than one plural form.

我一直在寻找如何解决这个问题，但是没有得到很远。 django-cms 使用一个名为 mptt 的层次树的应用程序，这是第一个（而且只有）应用程序在运行 pl 区域设置的django.mo文件时。

I've been looking at how to fix this, but haven't gotten very far. django-cms uses an app for hierarchical trees called mptt and this is the first (and only?) application it trips on, while running the django.mo file for the pl locale.

推荐答案

看起来像在0.5.1安装django-mptt中没有删除以下行：

It looks like the following line wasn't removed in the 0.5.1 install of django-mptt:

"Plural-Forms: nplurals=INTEGER; plural=EXPRESSION;\n"

可以在这里找到更改集： https://github.com / django-mptt / django-mptt / commit / 4b6a9758396450651bc2d02b2c7d49bac6cd3f25

此问题已修复为0.5.2，升级到此版本会使错误发生离开。

This issue has been fixed as of 0.5.2 and upgrading to this version makes the error go away.
