Please create an exact repro code on repl.it.

hi @icebob this is th repl.it:

[icebob]

I mean a working example that works on repl.it without transporter and MySQL (use sqlite)

[aheadrox]

Work with the _id field.

@aheadrox What do you mean here exactly?
I'm facing to same issue, using postgresql with this settings in the service

// membership.service
...
settings: {
  fields: ["id", "role", "userId", "communityId", "user"],
  populates: {
    "user": {
      field: "userId",
      action: "users.get",
      params: {
        fields: ["id", "name", "email", "avatar"]
      }
    }
  }
}
...

when calling it I have this piece of code

return ctx.call('membership.find', {
  query: {
    communityId
  },
  populate: ["user"]
});

[irzhywau]

@icebob I confirm this issue as stated in my previous comment
What I find weird is that when I remove the query section and only let populate in the call args it seems working. but when a query is added into the args the populate doesn't work

With query

mol $ call membership.find '{"populate":["user"], "query": {"communityId": 1}}'
>> Call 'membership.find' with params: { populate: [ 'user' ], query: { communityId: 1 } }
>> Execution time:18ms
>> Response:
[
  {
    id: 1,
    userId: 4,
    communityId: 1,
    role: 'citizen',
  }
]

Without query

mol $ call membership.find '{"populate":["user"]}'
>> Call 'membership.find' with params: { populate: [ 'user' ] }
>> Execution time:2ms
>> Response:
[
  {
    id: 1,
    userId: 4,
    communityId: 1,
    role: 'citizen',
    user: {
      id: 4,
      name: 'Tester',
      email: 'user@email.co',
      surname: null,
      avatar: null,
    }
  },
  {
    id: 2,
    userId: 1,
    communityId: 2,
    role: 'citizen',
    user: {
...

And this only works for find method, not working on list and get neither

Any idea?

[icebob]

I need a repro example (without any external tools and schemas) what I can debug to investigate the problem.

[irzhywau]

I think you can use the replit you setup, just need to define 2 different service which are related
My setup contains something else that are not really involved in this issue

[irzhywau]

@icebob here is a full reproduction https://replit.com/@irzhywau/issue-296
you can run npm run dev to run it

Im still wondering what Im doing wrong, either the library is buggy

[AndreMaz]

@irzhywau tested your repro and, after setting the userId@memberships.db to same value as _id@users.db, got the same result with both call membership.find '{"populate":["user"], "query": {"communityId": 1}}' and call membership.find '{"populate":["user"]}'

It seems that user field was properly populated, right? Can you please provide more info about the issue that you're facing?
