Error when trying to use eloquent relationships

Question

I am trying to get this problem fixed for hours now and I just don't get what I am doing wrong.

I want to get all entries of my tables where my id of posts equals the id of tables bewerbungens.

So I get all applications of every user existing with the corresponding title of the post the user applied to.

I asked a question here before and got resources to add relationships, which I did, as seen here:

Bewerbungen Model:

protected $fillable = [
    'bewerber_email',
    'Stellenanzeigen_ID',
    'is_Accepted',
    'accept_Date',
    'is_Canceled',
    'cancel_Date',
    'is_Received',
    'receive_Date',
    'is_Canceled_Bewerber',
    'cancel_Date_Bewerber',
    'lebenslauf_File',
    'zeugnis_File',
    'anschreiben_File',
    'weitere_Doks',
];

public function post() {
    return $this->belongsTo('Post', 'Stellenanzeigen_ID', 'Bewerbung_ID');
}

and here in my Post model:

protected $fillable = [
        'titel',
        'startdate',
        'enddate',
        'beschreibung',
        'standort',
        'type_name',
        'abteilung_name',
        'kontakt',
        'isActive',
        'lebenslauf',
        'zeugnisse',
        'anschreiben',
        'weitere_Doks',
        'is_Permitted',
        'job_start',
    ];

    public function bewerbungen() {
        return $this->belongsToMany(Bewerbungen::class);
    }

Here is my Controller code where I try to get the entries:

   $dummy = Post::with('Bewerbungen.post')->get();

But I get the error: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'portal.bewerbungen_post' doesn't exist (SQL: select bewerbungens .*, bewerbungen_post . post_id as pivot_post_id , bewerbungen_post . bewerbungen_id as pivot_bewerbungen_id from bewerbungens inner join bewerbungen_post on bewerbungens . id = bewerbungen_post . bewerbungen_id where bewerbungen_post . post_id in (1, 2, 3, 4))

I also tried this instead:

    $dummy = Post::where('id', 'Stellenanzeigen_ID')->get();

But it just returns an empty set.

How can I fix this?

Answer 1

The SQL Error said that there's no bewerbungen_post table, since you use belongsToMany with only one argument. As mentioned here , if your relationship's intermediate table name is different with the Laravel Behavior, then add the relationship's intermediate table name to the second argument, or Laravel will join the two table for the relation table's name. For example:

public function bewerbungen() {
    return $this->belongsToMany(Bewerbungen::class, 'bewerbungen_post');
}

I've checked your previous question, and I think that the Post model joined directly to the Bewerbungen model, so the relation in the Post Model should looks like this:

public function bewerbungens(): HasMany
{
    // It's mean that `Post` has many `Bewerbungen` where `Stellenanzeigen_ID` = `posts.id`
    return $this->hasMany(Bewerbungen::class, 'Stellenanzeigen_ID', 'id'); 
}

And in the Bewerbungen model:

public function post(): BelongsTo
{
    // It's mean that `Bewerbungen` owned by Post as `Stellenanzeigen_ID` = `posts.id`
    return $this->belongsTo(Post::class, 'Stellenanzeigen_ID', 'id');
}

If you want to get Post with all Bewerbungen owned by Posts :

// You will get All Post with all Bewerbungen each Post
$posts = Post::with('bewerbungens')->get();

Vice versa:

// You will All Bewerbungen and One Post for every Bewerbungen
$bewerbungen = Bewerbungen::with('post')->get();

All details about relationship could be found in Laravel Documentation .
