Question

我有2个csv文件。

Person.csv

ID,PetID,Jumps
1,101,Yes
2,102,No
3,103,Yes

Pet.csv

ID,Name
101,Dog
102,Cat
103,Rabbit

我正在编写ETL以使用这两个实体填充我的图表。我想在Person和Pet之间添加一个HAS_PET边。我也希望这个边缘有一个名为Jumps的属性。我怎样才能做到这一点？

我尝试了如下，

{
    "source":{
        "file":{
            "path":"C:/Users/60886/Project/person.csv"
        }
    },


    "extractor":{
        "row":{

        }
    },


    "transformers":[
        {
            "csv":{

            }
        },
        {
            "vertex":{
                "class":"Person"
            }
        },
        {
            "edge":{
                "class":"HAS_PET",
                "joinFieldName":"PETID",
                "lookup":"PET.ID",
                "direction":"out",
                "unresolvedLinkAction":"NOTHING"
            }
        }
    ],
    "loader":{
        "orientdb":{
            "dbURL":"remote:localhost/GratefulDeadConcerts",
            "dbType":"graph",
            "wal":false,
            "tx":false,
            "batchCommit":1000
        }
    }
}

在边缘变换器中使用<form action="" method="POST" id="payment-form"> <span class="payment-errors"></span> <div class="form-row"> <label> <span>Card Number</span> <input type="text" size="20" data-stripe="number"/> </label> </div> <div class="form-row"> <label> <span>CVC</span> <input type="text" size="4" data-stripe="cvc"/> </label> </div> <div class="form-row"> <label> <span>Expiration (MM/YYYY)</span> <input type="text" size="2" data-stripe="exp-month"/> </label> <span> / </span> <input type="text" size="4" data-stripe="exp-year"/> </div> <button type="submit">Submit Payment</button> </form> <?php require '../stripe-php/init.php'; //this next line is very wrong $post = 'client_secret=['sk_07C5ukIdqx'].'&grant_type=authorization_code&code='.$_GET['code']; $ch = curl_init(); curl_setopt($ch,CURLOPT_URL, $system['stipe']['token_url']); curl_setopt($ch,CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $result = curl_exec($ch); curl_close($ch); $decode = json_decode($result); \Stripe\Stripe::setApiKey("my_secret"); \Stripe\Charge::create(array( "amount" => 500, "currency" => "usd", "source" => $decode[2], // I am totally guessing the value will be in element #2 "description" => "Charge for test@example.com" ));来绑定边缘中的属性。例如：

edgeFields

请记住在边缘变换器之后从顶点删除“跳转”，使用：

"edge":{
   "class":"HAS_PET",
   "joinFieldName":"PETID",
   "lookup":"PET.ID",
   "direction":"out",
   "edgeFields": { "Jumps": "${input.Jumps}" },
   "unresolvedLinkAction":"NOTHING"
}

通过Orientdb ETL添加边缘属性
