用 Liquid 语言迭代对象数组

Question

我是 Liquid Language 的新手。我有一个用例，我想遍历对象数组并打印一些值。

可能我的语法不正确。

我有一组对象，如下所示。我从其他地方获取这些数据 api 我把它的一部分贴在这里了。

assign htd_product_ids = 
     [
        {
            "id": 113608,
            "car_name": "Maruti Suzuki Alto K10 VXi",
            "mileage": 13479,
            "make_year": 2018,
            "final_price": 345000,
            "fuel_type": "petrol",
            "full_url": "http://www.spinny.com/buy-used-cars/hyderabad/maruti-suzuki/alto-k10/vxi-kondapur-2018/113608/"
        },
        {
            "id": 113011,
            "car_name": "Maruti Suzuki Celerio VXi AMT",
            "mileage": 25257,
            "make_year": 2016,
            "final_price": 413000,
            "fuel_type": "petrol",
            "full_url": "http://www.spinny.com/buy-used-cars/hyderabad/maruti-suzuki/celerio/vxi-amt-kondapur-2016/113011/"
        },
        {
            "id": 112609,
            "car_name": "Maruti Suzuki Swift Dzire ZXI",
            "mileage": 54600,
            "make_year": 2015,
            "final_price": 541000,
            "fuel_type": "petrol",
            "full_url": "http://www.spinny.com/buy-used-cars/hyderabad/maruti-suzuki/swift-dzire/zxi-kondapur-2015/112609/"
        }
     ]

我想遍历这个数组并打印 car_name

{% for product in htd_product_ids %}
  {{forloop.index}}. {{product.car_name}}
{% endfor %}

forloop.index 工作正常但 product.car_name 没有打印车名。

如果有任何语法错误或其他问题，请指正。

您不能将 json 分配给变量。这是液体的一个已知问题。

使用液体沙箱进行测试(https://masterdatapoc.z6.web.core.windows.net/)，您使用的循环是正确的，尽管json可能是错误的：

来源Json:

{"htd_product_ids":  [
        {
            "id": 113608,
            "car_name": "Maruti Suzuki Alto K10 VXi",
            "mileage": 13479,
            "make_year": 2018,
            "final_price": 345000,
            "fuel_type": "petrol",
            "full_url": "http://www.spinny.com/buy-used-cars/hyderabad/maruti-suzuki/alto-k10/vxi-kondapur-2018/113608/"
        },
        {
            "id": 113011,
            "car_name": "Maruti Suzuki Celerio VXi AMT",
            "mileage": 25257,
            "make_year": 2016,
            "final_price": 413000,
            "fuel_type": "petrol",
            "full_url": "http://www.spinny.com/buy-used-cars/hyderabad/maruti-suzuki/celerio/vxi-amt-kondapur-2016/113011/"
        },
        {
            "id": 112609,
            "car_name": "Maruti Suzuki Swift Dzire ZXI",
            "mileage": 54600,
            "make_year": 2015,
            "final_price": 541000,
            "fuel_type": "petrol",
            "full_url": "http://www.spinny.com/buy-used-cars/hyderabad/maruti-suzuki/swift-dzire/zxi-kondapur-2015/112609/"
        }
     ]}

模板：

{% for product in htd_product_ids %}
  {{forloop.index}}. {{product.car_name}}
{% endfor %}

输出：

1. Maruti Suzuki Alto K10 VXi

2. Maruti Suzuki Celerio VXi AMT

3. Maruti Suzuki Swift Dzire ZXI
