SoftDelete cause relationship chaining query misplacement

[fzhan]

Class Address extends SoftDeletes() {
public function addressable()
{
return $this->morphTo();
}
public function scopeSpace($query) {
return $query->where('addressable_type' ,'spaces');
}
}

Address::space()->has('addressable');
Result in "
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'self_16c3ee36946631a2bc5bd5c263214040.deleted_at' in 'where clause' (SQL: select * from address where addressable_type = spaces and exists (select * from address as self_16c3ee36946631a2bc5bd5c263214040 where self_16c3ee36946631a2bc5bd5c263214040.id = self_16c3ee36946631a2bc5bd5c263214040.addressable_id and self_16c3ee36946631a2bc5bd5c263214040.deleted_at is null) and self_16c3ee36946631a2bc5bd5c263214040.deleted_at is null)

Where the last self_16c3ee36946631a2bc5bd5c263214040.deleted_at is null should have been address.deleted_at is null

Which Laravel version? Please include minor version too.

[fzhan]

@acasar version 5.2.31

[acasar]

Can you first update to the latest and then paste the query it gives you? Because the has query was changed a little in 5.2.35.

[fzhan]

@acasar
I've updated to 5.2.35 here's the new result:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'laravel_reserved_0.deleted_at' in 'where clause' (SQL: select * fromaddresswhereaddressable_type= spaces and exists (select * fromaddressaslaravel_reserved_0wherelaravel_reserved_0.id=laravel_reserved_0.addressable_idandlaravel_reserved_0.deleted_atis null) andlaravel_reserved_0.deleted_atis null)

It's a matter of softdelete, which the last bit should not be 'laravel_reserved_0', rather should be 'address'.

@fzhan does this issue still exist in the latest version of 5.2?

[GrahamCampbell]

Or indeed 5.3. 5.2 is technically closed for fixes now.

[orottier]

FYI it's still present in v5.3.29

[cansozeri]

it's still present in 5.4. Any solution ??

[meness]

I'm using v5.4.23 and the issue still exists.

The Model

class Request extends Model {

    /**
     * @var array
     */
    protected $dates = [
        'created_at',
        'deleted_at',
    ];

    use SoftDeletes;

    /**
     * @var array
     */
    protected $guarded = [
        'id',
        'created_at',
        'deleted_at',
    ];

    /**
     * @Relations
     * @return \Illuminate\Database\Eloquent\Relations\MorphTo
     */
    public function owner(): MorphTo {

        return $this->morphTo();
    }
}

The Scope

 * @param \Illuminate\Database\Eloquent\Builder $builder
 * @param \Illuminate\Support\Collection        $skills
 *
 * @return \Illuminate\Database\Eloquent\Builder
 */
public function scopeRelatedCollaborations(Builder $builder, Collection $skills) {
    return $builder->whereHas('owner', function (Builder $builder) use($skills)
    {
        // empty
    });
}

The Query Exception

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'laravel_reserved_0.deleted_at' in 'where clause' (SQL: select * from requests where exists (select * from requests as laravel_reserved_0 where laravel_reserved_0.id = laravel_reserved_0.owner_id and laravel_reserved_0.deleted_at is null) and laravel_reserved_0.deleted_at is null)

I'm using v5.4.23 and the issue still exists.

We're open to pull requests.

Just came across this too. Don't think I know it well enough to do a PR though.

Workaround was to use the local key instead of going into the polymorphic relationship.

$query->whereHas('periodical', function ($query) use ($type_id) {
    $query->where('typeable_id', $type_id);
});

Instead of

$query->whereHas('periodical.typeable', function ($query) use ($type_id) {
    $query->where('id', $type_id);
});

[staudenmeir]

Using SoftDeletes is not the problem. Queries like this can't work because Laravel doesn't support whereHas() on MorphTo relationships (#5429, #18523).

@laurencei This can be closed.

Just in case somebody stumbles with this issue, I've found a nice workaround here:

https://medium.com/better-through-code/using-wherehas-in-laravel-polymorphic-relations-2894f43217e4

[staudenmeir]

Laravel 5.8.27 added whereHasMorph(): #28928
