雄辯的laravel，克隆實體

Question

我也在嘗試克隆一個實體和OneTomany關系。 由於某些原因，$ entity-> hasManyRelation（）不是函數。 ：/

這是我的代碼：

$clonedWorksheet = Worksheet::where('id', $id)->get()->load('records');

$worksheet = new Worksheet;

$worksheet->employee_id = $request->employee;
$worksheet->workday = $request->workday;

$worksheet->save();

foreach ($clonedWorksheet->records() as $clonedRecord) {
  $record = new Record;

  $record->from = $clonedRecord->from;
  $record->to = $clonedRecord->to;
  $record->estimated = $clonedRecord->estimated;
  $record->place_id = $clonedRecord->place_id;
  $record->worksheet_id = $worksheet->id;
  $record->vehicle_id = $clonedRecord->vehicle_id;
  $record->tool_id = $clonedRecord->tool_id;
  $record->job_id = $clonedRecord->job_id;
  $record->comment = $clonedRecord->comment;

  $worksheet->records()->save($record);
}

還有其他想法，或者我做錯了什么？

Answer 1

問題在這里。

foreach ($clonedWorksheet->records() as $clonedRecord) {

records（）是模型中執行數據庫查詢的方法。 回報是雄辯的關系對象。 你要：

foreach($clonedWorksheet->records as $clonedRecord) {

要么

foreach ($clonedWorksheet->records()->get() as $clonedRecord) {

模型具有復制函數 ，該函數會將循環的主體縮減為：

$record = $cloneRecord->replicate();
$record->worksheet_id = $worksheet->id;
$record->save();
