We know that embedded documents work better in MongoDB. I don’t want to lose the benefits of reference while taking advantage of this. For this, I want to apply both reference and embedded approaches together.
For example: Let’s say I have both car and engine document. I want to link them together, but not as a reference. I still want to manually update/delete at the same time.
What is the most logical way to do this? So far I’ve tried Smart Relationship and I’m looking for an easier way.
Also, should I use smart fields if I want to select from a list of engines when adding cars? this requires a lot of manual work. Because I have too many relationships in my project
Thank you.
Hey @Melis_Tekin, and welcome to our community 
I’m guessing that you are currently using forest-express-mongoose your agent, is that correct?
We do provide a feature called fields flattenner for mongoose (Documentation is available here) that may be helpful in your case.
If you are using @forestadmin/mongoose-datasource, then maybe the following documentation could lead to potential solution.
Let me know if that helps.

Thank you for your answer. I didn’t pay attention to this feature.
When adding cars with Flatten I can’t detect pre-added documents in engine collection. Is there any way to detect this?

Could you give me more details about the document itself, as well as the behavior you are having vs the behavior you are expecting?
Thanks in advance
