How to update multiple record in angular 5. 

 

 

below code for single row update. 

editCustomTableRecord(index, record) {
    debugger;
    let filteredArray = this.CustomTables.customTableFieldList.filter(i => i.isKey == true);
    if (filteredArray.length > 0) {
      if (this.customTableRecordIds == null) {
        this.customTableRecordIds = index + ",";
      }
      else {
        this.customTableRecordIds += index + ",";
      }
      this.editCustomRecord = record;
      this.editRecord[index] = true;
    }
    else {
      swal();
    }
  }

 and now below code for multiple record save:

saveAllCustomTableRecord() {
    debugger;
    this.customTableRecordIds.forEach(customTableRecordId => {
      if (customTableRecordId != ',') {
        this.clixzService.customtablerecordService.putCustomTableRecord(this.customTableId, this.CustomTableRecords[customTableRecordId]).then(customeRecord => {
          this.responseModel.createObject(customeRecord);
          if (this.responseModel.isError == false) {
            this.editRecord[customTableRecordId] = false;
          }
          else {
            swal('Opps...', '', 'error');
          }
        });
      }
    });
  }

 

but does not save data. already get  customTableRecordIds.
