Question

我正在编写一个测试用例，以确保所有关键字段（如total_interactions，shares，comments和like）都是哈希中存在的键。

不确定我为什么会遇到这个例外：

 NoMethodError: undefined method `has_key?' for ["total_interactions", {"value"=>1170.0}]:Array

以下是我签到的哈希：

{13=>{"total_interactions"=>{"value"=>1170.0}, "shares"=>{"value"=>850.0}, "comments"=>{"value"=>0.0}, "likes"=>{"value"=>320.0}}, 17=>{"total_interactions"=>{"value"=>701.0}, "shares"=>{"value"=>300.0}, "comments"=>{"value"=>0.0}, "likes"=>{"value"=>401.0}}, 12=>{"total_interactions"=>{"value"=>203.66666666666666}, "shares"=>{"value"=>100.66666666666667}, "comments"=>{"value"=>0.0}, "likes"=>{"value"=>103.0}}, 22=>{"total_interactions"=>{"value"=>11.0}, "shares"=>{"value"=>2.0}, "comments"=>{"value"=>0.0}, "likes"=>{"value"=>9.0}}}

这是应该执行此操作的方法。

def test_aggs_response_populated(aggs_results)
    aggs_results.each do |k,v|
        if(v.class == Hash)
            contains_interactions = false
            contains_shares = false
            contains_comments = false
            contains_likes = false

            v.each do |hash_item|
                contains_interactions = hash_item.has_key?("total_interactions")
                contains_shares = hash_item.has_key?("shares")
                contains_comments = hash_item.has_key?("comments")
                contains_likes = hash_item.has_key?("likes")
            end

            assert_equal(true, contains_interactions)
            assert_equal(true, contains_shares)
            assert_equal(true, contains_comments)
            assert_equal(true, contains_likes)
        end
    end
end

你循环遍历哈希两次。你不想在键/值对上使用has_key。

你应该改变

v.each do |hash_item|
    contains_interactions = hash_item.has_key?("total_interactions")
    contains_shares = hash_item.has_key?("shares")
    contains_comments = hash_item.has_key?("comments")
    contains_likes = hash_item.has_key?("likes")
end

到

contains_interactions = v.has_key?("total_interactions")
contains_shares = v.has_key?("shares")
contains_comments = v.has_key?("comments")
contains_likes = v.has_key?("likes")

无法检查ruby哈希是否包含填充的某些字段
