Question

Hospital Table
id | name | address
-----------------------

Hospital_Key Table
id | hospital_id(fk of Hospital Table) | type
-----------------------------------------------

Hospital_Column Table
id | hospital_id(fk of Hospital Table) | name
---------------------------------------------------------

Hospital_fields Table

id | Hospital_Key_id(fk of Hospital_Key Table) | Hospital_col_id(fk of Hospital_Column Table) | data
------------------------------------------

---------------------------------------------------------------

我想复制/克隆任何记录和子记录的所有数据例如医院表的一条记录从医院获取数据，Hospital_Key，Hospital_Column 并使用新的主键复制同一表中的所有数据。

    $input = $request->all();

    $library = Library::with('key', 'col','key.field')->findOrFail($input['lib_id']);
    $new = $library->replicate();
    $new->user_id = Auth::id();
    $new->privacy_setting = 'Private';
    $new->push();

    $library->relations = [];

    $library->load('key', 'col','key.field');
    $relations = $library->getRelations();

    foreach ($relations as $relation => $items) {

        foreach ($items as $item) {

            $newfield = $new->{$relation}()->create($item->toArray());
        }
    }

上面的代码确实复制了Hospital，Hospital_Key，Hospital_Column的记录上面的代码不会复制Hospital_fields（grandchild）的记录
