Rails 只从另一个数组中获取数组元素

Question

我得到了以下查询的结果：

query

class SyncResult
  def self.query(products)
    Imports::Product
      .order(:last_sync_at)
      .pluck(:id, :name, :code, :sync_result, :last_sync_at)
      .map do |id, name, code, result, last_sync_at|
        {
          id: id,
          name: name,
          code: code,
          result: result,
          last_sync_at: last_sync_at
        }
      end
  end
end

query result

=> [{:id=>"611ea9a7392ab50013cf4713", :name=>"2-Tone Hoodie", :code=>"SS22CH013", :result=>nil, :last_sync_at=>nil},
     {:id=>"60ec84062f25d400150b351c", :name=>"5-Pocket Denim", :code=>"SS22WP014", :result=>nil, :last_sync_at=>nil},
     {:id=>"61966dc83e81dd001731ccd7", :name=>"Zip Shirt Jacket", :code=>"FW22WT001", :result=>nil, :last_sync_at=>nil},
     {:id=>"61d5cab6b41408001b0e9376", :name=>"Yankees Satin Varsity Jacket", :code=>"FW22WJ021", :result=>nil, :last_sync_at=>nil}]

products = ['SS22CH013', 'FW22WJ021']

现在我只想获取这些包含来自 products 数组的代码的数组哈希元素。最终结果应该是：

=> [{:id=>"611ea9a7392ab50013cf4713", :name=>"2-Tone Hoodie", :code=>"SS22CH013", :result=>nil, :last_sync_at=>nil},
{:id=>"61d5cab6b41408001b0e9376", :name=>"Yankees Satin Varsity Jacket", :code=>"FW22WJ021", :result=>nil, :last_sync_at=>nil}]

Answer 1

您可以通过以下方式达到预期的效果。

正在更新查询以获取给定代码的产品

products = ['SS22CH013', 'FW22WJ021']

Imports::Product
  .where(code: products)
  .order(:last_sync_at)
  .pluck(:id, :name, :code, :sync_result, :last_sync_at)
  .map do |id, name, code, result, last_sync_at|
    {
      id: id,
      name: name,
      code: code,
      result: result,
      last_sync_at: last_sync_at
    }

正在更新查询以获取给定代码的产品（无需 pluck）

products = ['SS22CH013', 'FW22WJ021']

Imports::Product
  .where(code: products)
  .order(:last_sync_at)
  .select(:id, :name, :code, :sync_result, :last_sync_at)
  .map(&:attributes)

对查询结果使用 select

 query_result = [{:id=>"611ea9a7392ab50013cf4713", :name=>"2-Tone Hoodie", :code=>"SS22CH013", :result=>nil, :last_sync_at=>nil},
 {:id=>"60ec84062f25d400150b351c", :name=>"5-Pocket Denim", :code=>"SS22WP014", :result=>nil, :last_sync_at=>nil},
 {:id=>"61966dc83e81dd001731ccd7", :name=>"Zip Shirt Jacket", :code=>"FW22WT001", :result=>nil, :last_sync_at=>nil},
 {:id=>"61d5cab6b41408001b0e9376", :name=>"Yankees Satin Varsity Jacket", :code=>"FW22WJ021", :result=>nil, :last_sync_at=>nil}]

 products = ['SS22CH013', 'FW22WJ021']
 query_result.select{ |product| products.include?(product[:code]) }

Rails get only array elements from another array
