Call to a member function wrap() on null

[blackakula]

When trying to use static method whereHas of the Model, Call to a member function wrap() on null fatal error appears.

Reason: Jenssegers\Mongodb\Query\Builder class has no grammar property set.

Call stack:

in Relation.php line 282
at FatalErrorException->__construct('message' => '???', 'code' => '???', 'severity' => '???', 'filename' => '???', 'lineno' => '???', 'traceOffset' => '???', 'traceArgs' => '???', 'trace' => '???') in HandleExceptions.php line 133
at HandleExceptions->fatalExceptionFromError('error' => '???', 'traceOffset' => '???') in HandleExceptions.php line 118
at HandleExceptions->handleShutdown() in HandleExceptions.php line 0
at Relation->wrap('value' => '???') in BelongsTo.php line 94
at BelongsTo->getRelationCountQuery('query' => '???', 'parent' => '???') in Builder.php line 583
at Builder->has('relation' => '???', 'operator' => '???', 'count' => '???', 'boolean' => '???', 'callback' => '???') in Builder.php line 644
at Builder->whereHas('relation' => '???', 'callback' => '???', 'operator' => '???', 'count' => '???') in Model.php line 3459

Is there any workaround?

What version are you using?

I'm using ^2.2 in composer.json and can't use whereHas on a belongsTo relation. I need to select that users that has a category which has some text in the title, but no idea how to do this without whereHas. Any clue?

Thanks for your work on this plugin

@jenssegers
v2.2.4 in my composer.lock

[jenssegers]

Fixed in last version.

I've tried to update to v2.3.2
It still fails with Call to undefined method Jenssegers\Mongodb\Query\Builder::getHasCompareKey() (I see it's already existing #730 issue).

Implementation of \Jenssegers\Mongodb\Eloquent\Builder::addHasWhere has call to $relation->getHasCompareKey(), where $relation is instance of \Jenssegers\Mongodb\Relations\BelongsTo.

Take into account, that parent implementation of this method (\Illuminate\Database\Eloquent\Builder::addHasWhere) doesn't have call to getHasCompareKey and that's why works.
So, it's still not possible to use static::whereHas like original one.

@blackakula have you solved this? I need to use whereHas on my application but don't know how.

Thanks

[blackakula]

@Lloople Nope. I have no idea how to overcome this. Waiting for #730 to be solved.

Anyone got this resolved?

[Lloople]

Nope, no news. I ended up filtering the collection...

Still an issue in v3.0.2, I understand it's complicated.

Like mentioned above filtering collections works as a alternative in my scenario as well.
People getting this as a google result: I would recommend working on the collection directly and use the where method.

Only issue I've had so far though, great work! :)
