Noes not include through properties when querying at a 2nd level

[frankorama]

we have a Team model linked to a Member model though a TeamRole model. In the TeamRole we define "canCreate", "canUpdate", etc. permissions. This is a hasManyThrough relation.

Team <--> TeamRole <--> Member

Next we have a document model, where the author property is a relation (belongsTo) Members, and the team property (belongsTo) Team.

Document.team --> Team
Document.author --> Membe

To query the documents and get the author and team, I perform the following include:
{"include":["author","team"]}
Works great.

Now i want to get the team members at the same time:
{"include":["author",{"team":"members"}]}
Now I have the team with a list of members, but I don't have any data from the TeamRole model.

I tried using the mixin, but without success. Is there a different syntax that I'm not aware of?

attempt 1:
{"include":["author",{"team": "members", "includeThrough":true}]}

attempt 2:

{
  "include":{
    "relation":"team",
    "scope":{
      "include":{ 
        "relation":"members"
        },
      "includeThrough":true
    }
  }
}

Is your mixing meant to perform this way? Is it possible to get the member roles when including team from another model?

Looked through the code and saw that the properties are being added using the 'afterRemote' remote hook, and an include 2 levels down is not using a remove method to add the data, so to answer my own questions: no, this mixin will only work when calling the Team model with an include. not the Document model.

Yes that is exactly right.

Should be possible to make it work for your use case though.
Do you want to give it a try and create a PR for it? I am a bit busy this week.

Unfortunately I'm not a JS black-belt. I think i'll need to override the loopback functions that handle the include parameters and I don't know where to find them.
