HasManyThrough, fails to detect missing relation, when aquired by mapper->all()

[omegasteffy]

My setup for HasManyThrough
Vessel_entity <-> xTable <-> Vdr_entity

I can get a list of vdrs like this
$all_vdrs= $mapper->all('Entity\Vdr_entity')->with('vessels');
relations should be loaded

Now i create a foreach-loop to iterate.Within this a access $one_vdr->vessels
foreach ($all_vdrs as $one_vdr){
$cnt= $one_vdr->vessels->count(); //return 0, even if one or more vessels are present
$one_ves= $one_vdr->vessels->first();// works ok if there is a relation in the crosstable. It fails otherwise. I have no way of checking (exception handling could be a possibility)
}

I have tried $mapper->get(Entity\Vdr_entity,array('id =>1'));
in this case i can actually use the count() method

I see. This may be a problem with the with method not properly loading relations and getting them ready for use. I will have to take a look at this in further detail.

[vlucas]

Can you verify that it works properly without using the with method? I know it's not ideal since it generates many more queries, but I just want to see if we can at least get a working baseline.

[omegasteffy]

(not certain)
I believe it works if i leave out the with(), will verify next time i get to the code.

ok some protocode
$matching_ves= $mapper->all('Entity\Vessel_entity');
foreach($matching_ves as $one_ves){
//var_dump($one_ves);
echo 'id:'.$one_ves->id.", vdrs cnt".$one_ves->vdrs->count().'
';
}
id:78, vdrs cnt0
id:79, vdrs cnt0
id:80, vdrs cnt0
id:81, vdrs cnt0
id:82, vdrs cnt0
id:83, vdrs cnt0
id:84, vdrs cnt0
id:85, vdrs cnt0
id:86, vdrs cnt0
id:87, vdrs cnt0
id:88, vdrs cnt0
id:89, vdrs cnt0

---

leaving out the with('vdrs')
id:78, vdrs cnt0
id:79, vdrs cnt0
id:80, vdrs cnt1
id:81, vdrs cnt1
id:82, vdrs cnt1
id:83, vdrs cnt1
id:84, vdrs cnt1
id:85, vdrs cnt1
id:86, vdrs cnt1
id:87, vdrs cnt1
id:88, vdrs cnt0
id:89, vdrs cnt0

So the problem seems to be the eager loading fails.
or perhabs rather the count() can not be trusted.

I am currently trying to create a test scenario to reproduce this issue.

[omegasteffy]

Great to hear. Reply if you have difficulties reproducing.

[vlucas]

There is definitely an issue with the with eager-loading method and HasManyThrough relations. I will take a deeper look and get it sorted out.

This has been solved with the release of Spot v2. Due to poor architecture that will lead to invariable replication of code, this will not be solved in this version of Spot.
