Error Missing required parameters for [Route] after upgrading Laravel 5.8 to 6.0-CodePudding

The

I have tried to find error and update route using _ or - but still can't solve this error:

any idea to solve this issue?

Thank You in Advance...

===Update

I suspect error here:

$datatables = app('datatables')->of($model) ->addColumn('action', function ($model) { return "<a href='". route('playlist-song.show', ['id' => $model->id]) ."' class='btn btn-success btn-sm'></a>" . " <a href='". route('playlist-song.edit', ['id' => $model->id]) . "' class='btn btn-primary btn-sm'></a>" . " <a href='#' onClick='modalDelete(".$model->id.")' class='btn btn-sm btn-danger'></a>"; });

Update the URL like below still can not solve the problem:

href='". {{ route('playlist-song.show', ['playlist-song' => $model]) }}."'

href="{{ route('playlist-song.show', ['playlist-song' => $model]) }}"

CodePudding user response：

Your error tells you that your playlist_song parameter is missing. You will need to specify its value. A try would be

$datatables = app('datatables')->of($model) ->addColumn('action', function ($model) { return "<a href='". route('playlist-song.show', ['playlist_song' => $model->id]) ."' class='btn btn-success btn-sm'></a>" . " <a href='". route('playlist-song.edit', ['playlist_song' => $model->id]) . "' class='btn btn-primary btn-sm'></a>" . " <a href='#' onClick='modalDelete(".$model->id.")' class='btn btn-sm btn-danger'></a>"; });

This specifies the parameter. If you still have problems, then let me know what your new error message/problem is.
