将csv导入文档模型

Question

我试图使用ETL将csv文件导入Orientdb中的document Model --我不知道这作为新手是否正确，也不知道关于文档模型的文档不多，但我尝试的是：

{
  "config": {
    "log": "debug"
  },
  "begin": [],
  "source": {
    "file": {
      "path": "C:/Users/M/Desktop/files/lact.csv"
    }
  },
  "extractor": 
{ "csv": 
      {  "separator": ",", 
         "nullValue": "NULL"
      }
  },
  "transformers": [
    {
      "log": {}
    }
  ],
  "loader": {
    "orientdb": {
      "dbURL": "plocal:../databases/Model_doc",



       "dbType": "document",
      "classes": [
        {
          "name": "Annotations"
        },


      ]
    }
  },
  "end": []
}

在显示文件内容的解析后，我得到了这样的说法: orientdb调试侧弯:在类'null‘中找到了0个文档

Csv文件

"Entry","Entry_name","Status","Protein_names","Gene_names","Organism","Length","Cross_reference(STRING)"
"Q29836","1B67_HUMAN","reviewed","HLA class I histocompatibility antigen, B-67 alpha chain (MHC class I antigen B*67)","HLA-B HLAB","Homo sapiens (Human)","362","9606.ENSP00000399168;"
"P30501","1C02_HUMAN","reviewed","HLA class I histocompatibility antigen, Cw-2 alpha chain (MHC class I antigen Cw*2)","HLA-C HLAC","Homo sapiens (Human)","366",""
"P30508","1C12_HUMAN","reviewed","HLA class I histocompatibility antigen, Cw-12 alpha chain (MHC class I antigen Cw*12)","HLA-C HLAC","Homo sapiens (Human)","366",""
"Q29960","1C16_HUMAN","reviewed","HLA class I histocompatibility antigen, Cw-16 alpha chain (MHC class I antigen Cw*16)","HLA-C HLAC","Homo sapiens (Human)","366",""

Answer 1

我试过你的代码，我有同样的信息：

[orientdb] DEBUG orientdb: found 0 documents in class 'null'

但我已经能够导入所有的数据，正如你可以从我的截图中看到的。

正如RobertoFranchini所说，要做到这一点，您必须添加以下内容：

 "transformers": [
{
  "log": {}
},
{
  "field": {
    "fieldName": "@class",
    "value": "Annotations"
  }
}
],

我对你的csv文件做了个小小的修改：

Entry,Entry_name,Status,Protein_names,Gene_names,Organism,Length,Cross_reference(STRING)
Q29836,1B67_HUMAN,reviewed,HLA class I histocompatibility antigen, B-67 alpha chain (MHC class I antigen B*67),HLA-B HLAB,Homo sapiens (Human),362,9606.ENSP00000399168
P30501,1C02_HUMAN,reviewed,HLA class I histocompatibility antigen, Cw-2 alpha chain (MHC class I antigen Cw*2),HLA-C HLAC,Homo sapiens (Human),366,
P30508,1C12_HUMAN,reviewed,HLA class I histocompatibility antigen, Cw-12 alpha chain (MHC class I antigen Cw*12),HLA-C HLAC,Homo sapiens (Human),366,
Q29960,1C16_HUMAN,reviewed,HLA class I histocompatibility antigen, Cw-16 alpha chain (MHC class I antigen Cw*16),HLA-C HLAC,Homo sapiens (Human),366,
Q29865,1C18_HUMAN,reviewed,HLA class I histocompatibility antigen, Cw-18 alpha chain (MHC class I antigen Cw*18),HLA-C HLAC,Homo sapiens (Human),366,

所有的数据都是输入的。

希望能帮上忙。

致以问候。

您需要为文档分配一个类，将字段转换器添加到链中，就在日志之后。

"transformers": [
{
  "log": {}
},
{
  "field": {
    "fieldName": "@class",
    "value": "Annotations"
  }
}
],
