Django不翻译过滤器标签

Question

我使用django过滤器在我的网站上进行过滤，过滤器标签在每一页上都被正确翻译，除了两页。我检查了所有常见的问题，如确保il8n加载到两个页面、测试locale文件夹的路径、重新启动服务器、检查中间件和其他设置、检查翻译文件中的模糊标记等。我能想到的唯一相似之处是，它们都使用Django的内置Paginator，而没有在网站上的其他网页做。这足以破坏翻译吗？我把其中一页的代码包括进来，希望有人能告诉我发生了什么。如果有人想看到其他代码片段，github就是here

我已经解决了这个问题，但我会把答案贴在这里，以防其他人遇到同样的问题。你知道吗

我没有找出问题的根源（尽管我现在怀疑这是因为我定义了自定义过滤器，而不是让它们自动生成）；但是我发现最有效的解决方案是在过滤器的init函数中分别定义每个过滤器的标签，如下所示：

    def __init__(self, *args, **kwargs):
        super(StudentFilter, self).__init__(*args, **kwargs)

        # Adding custom translatable labels to autogenerated filters
        self.filters['year'].label = _("Year:")

希望这对别人有帮助。你知道吗
