雄辩的laravel，克隆实体

Question

I'm trying to clone an entity and the OneTomany relation too. For some reason, the $entity->hasManyRelation() is not a function. :/

Here's my code.:

$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);
}

Any other idea, or what am I doing wrong?

Answer 1

The problem is here.

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

The records() is the method in the model that does the database query. The return is an eloquent relationship object. You want:

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

Or

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

Models have a replicate function , which would cut the body of your loop down quite a bit to just:

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