示例

过滤器

此示例将find过滤器添加到Liquid环境中。您可以将find视为标准map和where过滤器的先进替代品。它接受一个JSONPath字符串参数，并将其应用于过滤器的左侧值。

from liquid import Environment
from liquid_jsonpath import Find

env = Environment()
env.add_filter("find", Find())

data = {
    "users": [
        {
            "name": "Sue",
            "score": 100,
        },
        {
            "name": "John",
            "score": 86,
        },
        {
            "name": "Sally",
            "score": 84,
        },
        {
            "name": "Jane",
            "score": 55,
        },
    ]
}

template = env.from_string("{{ data | find: '$.users.*.name' | join: ' ' }}")
print(template.render(data=data))  # Sue John Sally Jane

标签

此示例用支持通过JSONPath表达式管道化可迭代对象的标签替换了标准的{% for %}标签。

from liquid import Environment
from liquid_jsonpath import JSONPathForTag

env = Environment()
env.add_tag(JSONPathForTag)

data = {
    "users": [
        {
            "name": "Sue",
            "score": 100,
        },
        {
            "name": "John",
            "score": 86,
        },
        {
            "name": "Sally",
            "score": 84,
        },
        {
            "name": "Jane",
            "score": 55,
        },
    ]
}

template = env.from_string(
    "{% for name in data | '$.users.*.name' %}"
    "{{ name }}, "
    "{% endfor %}"
)
print(template.render(data=data))  # Sue, John, Sally, Jane,
