Objection.js 條件插入圖

Question

我正在為我們的軟件創建導入 function，其中 Excel 文件可用於將數據導入系統。 我們使用 objection.js（創建工具），我使用 insertGraph() 插入內容。 我的問題是我只想在提供數據時導入關系。 如何使 insertGraph 有條件？

.insertGraph(
                  [
                      {
                          '#id': 'boat',
                          ...arrayList[i],
                          insertedBy: req.user.sub,
                          berthAssignments: [
                              {
                                  insertedBy: req.user.sub,
                                  from: relationsData[i].ownershipSince,
  
                                  boat: [
                                      {
                                          id: '#ref{boat.id}'
                                      }
                                  ],
                                  berth: [
                                      {
                                          id: berthId[0]?.id
                                      }
                                  ]
                              }
                          ],
                          electricMeterAssignments: [
                              {
                                  insertedBy: req.user.sub,
                                  from: relationsData[i].electricMeterSince,
  
                                  electricMeter: [
                                      {
                                          id: meterId[0]?.id
                                      }
                                  ],
                                  boat: [
                                      {
                                          id: '#ref{boat.id}'
                                      }
                                  ]
                              }
                          ],
                          winterStorageAssignments: [
                              {
                                  insertedBy: req.user.sub,
                                  from: relationsData[i].winterStorageSince,
  
                                  winterStorage: [
                                      {
                                          id: storageId[0]?.id
                                      }
                                  ],
                                  boat: [
                                      {
                                          id: '#ref{boat.id}'
                                      }
                                  ]
                              }
                          ]
  
                      }
                  ],
                  {
  
                      relate: true,
                      allowRefs: true
                  }

我還嘗試使用插入和 if 條件以傳統方式執行此操作，但這也無法正常工作：

  .insert(arrayList[i])
        .then(async insertedBoat => {
            if (relationsData[i].berthHandle) {
                console.log('berthHandle')
                await BerthAssignment
                    .query(req.dbConnection)
                    .insert({
                        bcm_berths_id: berthId[0].id,
                        bcm_boats_id: insertedBoat.id,
                        from: relationsData[i].berthSince,
                        insertedBy: req.user.sub,
                    })
                    .catch((error) => { console.log(error); throw next(error); });
            } else if (relationsData[i].electricMeters) {
                console.log('electricMeter')

                await ElectricMeterBoat
                    .query(req.dbConnection)
                    .insert({
                        bcm_electric_meters_id: meterId[0].id,
                        bcm_boats_id: insertedBoat.id,
                        from: relationsData[i].electricMeterSince,
                        insertedBy: req.user.sub,
                    })
                    .catch((error) => { console.log(error); throw next(error); });
            } else if (relationsData[i].winterStoragehandle) {
                console.log('Hallo')

                await WinterStorageAssignment
                    .query(req.dbConnection)
                    .insert({
                        bcm_winter_storages_id: storageId[0].id,
                        bcm_boats_id: insertedBoat.id,
                        from: relationsData[i].winterStorageSince,
                        insertedBy: req.user.sub,
                    })
                    .catch((error) => { console.log(error); throw next(error); });
            } else if (owner !== null) {
                console.log('asdflksdafsdaf')
                await BoatOwner
                    .query(req.dbConnection)
                    .delete()
                    .where({
                        bcm_boats_id: insertedBoat.id
                    })
                    .catch(() => null);
                await BoatOwner
                    .query(req.dbConnection)
                    .insert({
                        bcm_boats_id: insertedBoat.id,
                        bcm_persons_id: personId[0]?.id,
                        // bcm_companies_id: companyId[0]?.id,
                        isOwnerSince: relationsData[i]?.ownershipSince,
                        insertedBy: req.user.sub
                    })
                    .catch((error) => { console.log(error); throw next(error); });
            }
        })

有人可以幫助我嗎？ 非常感謝！

你的朋友會是upsertGraph

我曾經將它用於需要一些深層嵌套插入/更新的應用程序，它就像.upsertGraph(data, {insertMissing: true})一樣簡單

但是您可以從文檔中獲得更具體的選項來了解使用它時會發生什么關系：

const options = {
  // Only enable `unrelate` functionality for these two paths.
  unrelate: ['pets', 'movies.reviews'],
  // Only enable `relate` functionality for 'movies' relation.
  relate: ['movies'],
  // Disable deleting for movies.
  noDelete: ['movies']
};
