QUESTION
I don't know if it is expected to be this way but I thought it is strange since changes the query results.
When I execute the query below I get my entity with only 2 "Mensagens" entity because i'm filtering only the actives so it's right, I have 2 active entities on my database and 1 inactive.
...ANSWER
Answered 2022-Jan-25 at 07:30This is sort of explained in Filtered include documentation:
Caution
In case of tracking queries, results of Filtered Include may be unexpected due to navigation fixup. All relevant entities that have been queried for previously and have been stored in the Change Tracker will be present in the results of Filtered Include query, even if they don't meet the requirements of the filter. Consider using
NoTrackingqueries or re-create the DbContext when using Filtered Include in those situations.
So most likely your context is not clean when doing tracking tests. And even if it is clean, in case it is used for executing other queries, the navigation fixup can load some non satisfying filter entities later since it keeps track (has access) to all tracked entities.
In general you cannot rely on content of navigation property of a tracked entity since it may be updated at any time during the lifetime of the context until the context is disposed or entity detached from change tracker. If you need full control, the either use no tracking entity queries or DTO/ViewModel etc. projecting queries and select exactly what you want (no Include / ThenInclude, just plain LINQ).

QUESTION
How can I define a Doctrine property in a parent class and override the association in a class which extends the parent class? When using annotation, this was implemented by using AssociationOverride, however, I don't think they are available when using PHP 8 attributes
Why I want to:
I have a class AbstractTenantEntity whose purpose is to restrict access to data to a given Tenant (i.e. account, owner, etc) that owns the data, and any entity which extends this class will have tenant_id inserted into the database when created and all other requests will add the tenant_id to the WHERE clause. Tenant typically does not have collections of the various entities which extend AbstractTenantEntity, but a few do. When using annotations, I handled it by applying Doctrine's AssociationOverride annotation to the extended classes which should have a collection in Tenant, but I don't know how to accomplish this when using PHP 8 attributes?
My attempt described below was unsuccessful as I incorrectly thought that the annotation class would magically work with attributes if modified appropriately, but now I see other code must be able to apply the appropriate logic based on the attributes. As such, I abandoned this approach and just made the properties protected and duplicated them in the concrete class.
My attempt:

Sometimes there is a need to persist entities but override all or part of the mapping metadata. Sometimes also the mapping to override comes from entities using traits where the traits have mapping metadata. This tutorial explains how to override mapping metadata, i.e. attributes and associations metadata in particular. The example here shows the overriding of a class that uses a trait but is similar when extending a base class as shown at the end of this tutorial.
Suppose we have a class ExampleEntityWithOverride. This class uses trait ExampleTrait:

Consider a program with the following two translation units:
...ANSWER
Answered 2021-Oct-26 at 07:51This program is well-formed and prints 1, as seen. Because S is defined identically in both translation units with external linkage, it is as if there is one definition of S ([basic.def.odr]/14) and thus only one enumeration type is defined. (In practice it is mangled based on the name S or S::x.)
This is just the same phenomenon as static local variables and lambdas being shared among the definitions of an inline function:

QUESTION
There are these two entities:
...ANSWER
Answered 2021-Jul-25 at 14:31Entity Framework Core configures one to one relationships by being able to detect the foreign key property, and thereby identify which is the principal and which is the dependent entity in the relationship.
First look at the existing database and check what is the dependant table, assuming it is the Employee, it should have a foriegn key to CompanyVehicle table. (It could be other way around in your case.)
1. Using EF Core convestions.
If Employee is the depentant table, add that exact foriegn key property name (let's assume it's Vehicle_Id) to your Employee entity. Follow 2nd method if you don't want to add a property to the class.
