如何在 Jinja 中过滤字典?

["7.1.9-1+ubuntu14.04.1+deb.sury.org+1","7.1.9-1+ubuntu14.04.1+deb.sury.org+1","7.1.6-2~ubuntu14.04.1+deb.sury.org+1"]如何获取整个字典元素?有希望吗? 解决方案 With dict2items 过滤器 于 2017 年 12 月添加，可以使用本机功能:- 调试:msg: "{{ dict(pkg | dict2items | json_query('[?value.latest].[key, value.latest]')) }}"结果:"msg": {"php7.1-readline": "7.1.9-1+ubuntu14.04.1+deb.sury.org+1","php7.1-xml": "7.1.9-1+ubuntu14.04.1+deb.sury.org+1"}I have a dictionary of packages with package-name being the key and a dictionary of some details being the value:{ "php7.1-readline": { "latest": "7.1.9-1+ubuntu14.04.1+deb.sury.org+1", "origins": [ "ppa.launchpad.net" ], "version": "7.1.6-2~ubuntu14.04.1+deb.sury.org+1", "www": "http://www.php.net/" }, "php7.1-xml": { "latest": "7.1.9-1+ubuntu14.04.1+deb.sury.org+1", "origins": [ "ppa.launchpad.net" ], "version": "7.1.6-2~ubuntu14.04.1+deb.sury.org+1", "www": "http://www.php.net/" }, "plymouth": { "version": "0.8.8-0ubuntu17.1" }, ....}I'd like to reduce the above to a dictionary with only the packages, that have the latest-attribute in their values.It would seem like json_query is the filter to use, but I can't figure out the syntax. The examples out there all seem to operate on lists of dictionaries, not dictionaries of same...For example, if I "pipe" the above dictionary into json_query('*.latest'), I get the list of the actual latest versions:[ "7.1.9-1+ubuntu14.04.1+deb.sury.org+1", "7.1.9-1+ubuntu14.04.1+deb.sury.org+1", "7.1.6-2~ubuntu14.04.1+deb.sury.org+1"]How can I get the entire dictionary-elements instead?Any hope? 解决方案 With dict2items filter added in December 2017, it is possible using native functionality:- debug: msg: "{{ dict(pkg | dict2items | json_query('[?value.latest].[key, value.latest]')) }}"The result:"msg": { "php7.1-readline": "7.1.9-1+ubuntu14.04.1+deb.sury.org+1", "php7.1-xml": "7.1.9-1+ubuntu14.04.1+deb.sury.org+1"} 这篇关于如何在 Jinja 中过滤字典?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
