I am going to implement a small and simple search feature in my project.
But got a question about the scenario I have right now. So hope to get
tips from here.
First of all, this is a rails app.
There are two models, A and C.
A has_many C.
That’s to say, it might have some situation like this:
A1 related to C1, C2, C3, C4
A2 related to C2, C3, C4, C5
A3 related to C2, C3, C4, C8
A4 related to C3, C4, C8, C9
A5 related to C4, C8, C9, C20
Use C2, C3, C4 as keyword, I can get A1, A2, A3
Use C4, C8, C9 as keyword, I can get A4, A5
I consider that this can be done by using something straightforward like
But that requires an iteration of A. And I concern that it would have
Any advice or idea about this requirement ?
Thank you all, guys.
