javascript - 使用 Ramda 统一有关对象的信息

Question

我需要您的支持才能在 ramda 中生成以下结果。

我已经采取了一些方法，并且已经达到了这些结果，但现在我需要的是通过生成以下结果的 ProductCode 进行合并，其中 serviceType 将是一个按持续时间排序和关联的数组:

我已经尝试过编写此代码，但持续时间数组会在信息到来时随机保存它，我需要持续时间内的第一个安排是“Garantia Extendida”，第二个安排是“Robo o Furto”，并且知道如何识别它所属的持续时间安排，例如:

Duration: {GE: ['12', '24'], RF: ['24']}

> const groupByTransaction = R.groupBy(R.prop('productCode'));

> item[0]),    ...R.pickAll(['updatedAt'], item[0]),   
> pdvIntegrationStatus: R.contains(R.pluck('pdvIntegrationStatus',
> item)[0], 'INTEGRATED'),    sapIntegrationStatus:
> R.contains(R.pluck('sapIntegrationStatus', item)[0], 'INTEGRATED'),   
> serviceType: R.pluck('serviceType', item),    duration_GE:

Answer 1

首先，请求:在发布进一步问题之前，请阅读 How to create a Minimal, Reproducible Example 。问题中的数据远多于演示所请求行为所需的数据。数组中的条目数量超出了需要的数量，并且它们的属性也超出了需要的数量。在输入和所需输出之间来回滚动以尝试了解您在做什么，这非常乏味，我几乎放弃了。

在下面的示例中，我减少了属性的数量，但保留了所有条目。其他属性不应对该技术产生任何影响。

所以下次，请在询问之前创建一个最小的示例。谢谢!

<小时/>

我对你的问题不太确定，但我认为这个示例满足了你的要求:

const combineTypes = (
  {serviceType: allTypes, ... base}, 
  {id, serviceType, duration, ... rest}
) => ({
  ... rest,
  serviceType: [... allTypes, serviceType],
  ... base,
  [`duration_${serviceType.code}`]: duration
})

const transform = pipe (
  groupBy (prop ('productCode')),
  values,
  map (reduce (combineTypes, {serviceType: []}))
)

(再次注意，并非您请求中的所有属性都包含在输出中。如果它们包含在输入中，它们应该会正确显示。)

我们删除其中的id。不同条目的数据有不同的 id，并且没有明确的方法将它们组合起来。如果我们需要保留所有这些，我们可以执行与 serviceType 类似的操作。

核心位于combineTypes函数，该函数提供给transform管道中的reduce。 transform 是标准的 Ramda 代码，我认为应该相当清楚。

如果这不能满足您的要求，请在问题中或作为评论添加一些说明。
