你能在指定液体标签中使用两个where条件吗

Question

能否在assignLiquid标签中使用两个where条件？

我在尝试bundle exec jekyll serve --trace:时遇到此构建错误

Liquid Exception: Liquid error (line 7): wrong number of arguments (given 4, expected 3) in party/democratic/index.md
Error: Liquid error (line 7): wrong number of arguments (given 4, expected 3)

这是有问题的液体标签：

{% assign people = site.data.people |  where: election_2020.office, 'U.S. President' and election_2020.party, 'Democratic' | sort: 'last_names' %}

无论在一个assign标签中是否可以有两个where过滤器，我都找不到文档。

附言：这是people.yml文件的示例：

-
id: 'julian-castro'
first_names: 'Julián'
last_names: 'Castro'
full_name: 'Julián Castro'
image: '/images/people/julian-castro-wikipedia.jpg'
gender: 'male'
image: '/images/people/julian-castro-wikipedia.jpg'
election_2020:
office: 'U.S. President'
address: 'P.O. Box 501'
latitude: '29.430018'
longitude: '-98.4987548'
city: 'San Antonio'

过滤器只允许将一个键值与另一个值进行比较。如果你想使用复杂的过滤，你可以使用where _exp过滤器。

{% assign people = site.data.people | where_exp: "someone", "someone.election_2020.office == 'U.S. President' and someone.election_2020.party == 'Democratic'" | sort: "last_names" %}
