如何在Zinnia中注册templatetag以显示特定类别的最新条目?

Here's a photo of the home template I'm integrating with Zinnia, in case it's helpful in clarifying the goal of creating the new templatetag(s).推荐答案这不是最漂亮的解决方案(主要是因为如果要保持站点地图的顺序，则必须在两个位置选择类别)，但是确实允许您根据各自的类别获取最新条目，如果其他在python方面缺乏专门知识的人希望实现此功能，我想与他人分享.This isn't the prettiest solution (mainly because you have to select your category in two places, if you want to keep your sitemap in order), but it does allow you to get recent entries based on their respective categories, and I want to share it in case somebody else who lacks thorough expertise in python is looking to implement this functionality.而且，如果您精通python，也许此解决方案会让您感到沮丧，足以发布更好的解决方案了:)And, if you are proficient with python, maybe this solution will upset you enough to post a better one :)从我可以从百日菊属的其他templatetags收集的上下文线索中，我推断出，如果"Featured = True"被"Featured"条目过滤掉，那么也许我可以将管理员中的条目模型扩展为包括其他类型的"Featured"复选框，与发布的条目的类别相对应.在这种情况下，我添加了"Featured_politics". From the context clues I could gather from Zinnia's other templatetags, I deduced that if "Featured=True" filtered by "Featured" entries, then maybe I could extend the entry model in the admin to included other types of "Featured" checkboxes, which would correspond with the categories of the entry posted. In this case, I added "Featured_politics." 然后，我对以下文件进行了更改(基本上，我在整个项目中搜索功能"，然后复制/粘贴了相应的代码，并将功能"更改为"featured_politics"):I then made changes to the following files (essentially, I searched for "featured" throughout the project, and copy/pasted the corresponding code, and changed "featured" to "featured_politics"): 百日草/admin/entry.py class EntryAdmin(admin.ModelAdmin): """ Admin for Entry model.
