Laravel - Data storing/fetching for current logged user

Question

I am trying to store and fetch the data for current logged user in laravel but I am not getting anything besides errors

[

Missing required parameters for [Route: authlyrics.show] [URI: painel/authlyrics/{authlyric}]. (View: /var/www/html/allup_lyrics_cms/resources/views/admin/userlyrics/index.blade.php)

]

I mean that I have two tables. One is users table which stores the data for login and other table is lyrics table, which stores lyrics the user will add to the site. How can I store this authenticated user lyrics and fetch the lyrics to list them in the index page? while lyrics and users are bound through user_id foreign key. My code is given here:

Lyrics Migration

**

Schema::create('lyrics', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->unsignedBigInteger('user_id')->nullable();
        $table->string('video_url');
        $table->string('title');
        $table->string('info');
        $table->string('slug');
        $table->text('lyric');
        $table->timestamps();
        $table->engine = 'InnoDB';

        $table->foreign('user_id')
            ->references('id')
            ->on('users')
            ->onDelete('cascade');
    });

Both tables, lyrics and users, are bound by foreign key but I don't seem to get to store the lyrics linking the user and feth the lyrics as well.. I need some sort of a BIIIG help please...

Answer 1

User.php

/**
 * The lyrics that belong to the user.
 *
 * @return BelongsToMany
 *
 */
public function lyrics()
{
    return $this->hasMany(Lyric::class);
}

Lyric.php

/**
 * The user that owns to the lyrics.
 *
 * @return BelongsTo
 *
 */
public function user()
{
    return $this->belongsTo(User::class);
}

Once you've got the relationships, you can get to the lyrics like this:

$user = auth()->user();  // Get the authenticated user.
$user->lyrics;

or

$lyrics = auth()->user()->lyrics;

To pass them to your view:

$lyrics = auth()->user()->lyrics;

return view('my.view', compact('lyrics');

If you are using route model binding, you can update your show() method:

public function show(Lyric $lyric)
{
    return view('admin.userlyrics.show', compact('lyric');
}

Your route might look something like:

Route::get('lyrics/{lyric}', 'LyricController@show');

In any event, you can always get the current user with auth()->user() . From there, you should have access to the relationships. Hope this helps!

UPDATE

Here's what your store method might look like. You may need to tweak it a bit to fit your needs, but this should get you going.

public function store(Request $request) {

    // Validate the request data.
    $attributes = $request->validate([
        'title' => 'required',
    ]);

    // Create a new Lyric instance and fill all of the fillable attributes.
    $lyric = new Lyric($attributes);

    // Populate anything that is not mass-assignable.
    $lyric->user_id = auth()->user()->id; // set things you want to be in control of.
    $lyric->slug = strtolower($request->title);  // example.

    ...

    $lyric->save();
}
