Efficient Data Handling: Storing Items in Laravel Parent Tables Before Creating Parent Row

Some time we need to create items for the parent before creating the parent row creates. So you can use this formula for doing that action.

add a new column on your child table named temp_id . After that when you are going to store that item, do like this -

public function storeChildData(Request $request){
        $attribute = new ChildModel();
        $attribute->temp_id = rand(1111,9999); // Add a random value to the attribute
        ...
        ...
        $attribute->created_by = Auth::id();
        $attribute->save();

        // Store value on session as a array
        $tempArray = session('attributeTempId', []);
        $tempArray[] = $attribute->temp_id;
        session(['tempId' => $tempArray]);

       ...
       ...
    }

Then go to your parent store method and add like this -

public function storeParentData(Request $request)

        $parent = new ParentModel;
        ...
        ...
        $parent->created_by = Auth::id();
        $parent->save();

        // Add this for update parent id on child
        ChildModel::whereIn('temp_id', session()->get('tempId'))->where('created_by', Auth::id())->update(['temp_id' => null, 'parent_id'=> $parent->id]);
        session()->flash('tempId');

        ...
        ...
    }
