How does Laravel check the latest relational model with specific conditions for a model?

My question asked by zookeeper on StackOverflow is to be answered. Stackoverflow. comques... a Package model with many Step models.

A Package model has many Step models. There are two types of Step fields: tinyint status field and timestamp field.
False configuration of A Package A with the following steps

• 18:; status: 1

• 19, status is 2

False configuration of a Package B with the following steps

• 19, status is 1

• 19, status is 2

• 19, status is 3

In this case, the latest step status of A is 2 and B is 3.

Then, how can I check the packages whose latest step status is 2?

I added zookeeper to the package model.

public function steps(){    return $this->hasMany('App\Step');}public function status(){    return $this->steps()->latest()->limit(1);}

Then, check the response.

Package::whereHas('status', function ($q) {    $q->where('status', 2);})->get();

However, pipeline cannot get the expected result.

The result is not the expected result. it indicates that, if the packages table has B in its dimension, I want to check the packages whose latest step status is 2, B is the latest 3, so the result should be blank. However, the result of this query is not empty, but contains B.

Then I continue to complete

public function status(){    return $this->hasOne('App\Step')->latest();}

The same is true.

Laravel, a beginner, is very confused about this problem. I also checked a lot of Google and did not have the desired answer. Hope you can help me!
