Investigate issues with includes

[glacials]

It seems this code is returning no record:

@race = Race.includes(entries: [:runner]).find(params[:id])

whereas this code is correctly returning a record:

@race = Race.find(params[:id])

Discovered while going through strict_loading audits in Rails 6.1.

@glacials: I can take a look at this 👍 Regarding the above, is your setup something like the following?

class Race
  has_many :entries
end

class Entry
  belongs_to :race
  belongs_to :runner
end

class Runner
  has_many :entries
end

race = Race.create
runner = Runner.create
entry = Entry.create(race: race, runner: runner)

[glacials]

Yep, exactly! Thanks for volunteering to take a look at this.

Sure thing! I should have included this above, but all three models mixing in FriendlyUUID? I.e.,

class Race
  include FriendlyUUID

  has_many :entries
end

class Entry
  include FriendlyUUID

  belongs_to :race
  belongs_to :runner
end

etc

@glacials, I'm not able to reproduce the error you're seeing. Can you take a look at my WIP PR and let me know if there's something I'm missing about the setup required to do so? Thanks!

Re-ping for @glacials in case you missed the above 🙇

Sorry for awol, have not had much free time. In my example actually only Race uses FriendlyUUID, the others use standard auto-incrementing integer IDs with no gems involved.

The link I provided above is the actual code base I encountered this in, if you're still having trouble with the test and interested enough to try to repro there. Thanks for all the effort, I really appreciate it!
