使用 Jbuilder 而不是下划线的 json 键中的连字符

Question

我正在尝试通过 jbuilder 制作这个 json

{
  "query": { 
    "bool": { 
      "must": [
        { "match": { "source-id":2}}
      ]
    }
  }
}

这是我的代码

query = Jbuilder.encode do |json|
                  json.query do
                    json.bool do
                      json.must do
                        json.match do
                          json.source-id source.id
                        end
                      end
                    end
                  end
                end

我收到了这个错误信息

问题在于source-id 键名中有连字符。如果source_id 用作键，请尝试这样做。

query = Jbuilder.encode do |json|
              json.query do
                json.bool do
                  json.must do
                    json.match do
                      json.source_id source.id
                    end
                  end
                end
              end
            end

更新::

否则，您可以这样做来格式化密钥：

Jbuilder.encode do |json|
  json.key_format!  ->(key) { (key=="source_id") ? "source-id" : key}
  json.query do
    json.bool do
      json.must do
        json.match do
          json.source_id source.id
        end
      end
    end
  end
end

转换所有字符串：

Jbuilder.encode do |json|
  json.key_format!  :dasherize
  json.query do
    json.bool do
      json.must do
        json.match do
          json.source_id source.id
        end
      end
    end
  end
end

或使用set! 语法，如json.set! "source-id", source.id
