We need to create a new model instance if we want to create a new record in the database using Laravel eloquent. Then we are required to set attributes on the model and call the save() method.
Example:
                    public functionsaveProduct(Request $request )  
                     $product = new product;  
                     $product->name = $request->name;  
                     $product->description = $request->name;  
                      $product->save();
