Hello hope all of you are well i want to select motherboard on the basis of socket and chipset supported by CPU but it can fetch all motherboard

1. **basically, i want to develop a website like pc part picker in Django I want to select a motherboard on the basis of socket and chipset supported by CPU problem is it can fetch all motherboard I want to select only those motherboard having the same socket and chipset stored in session problem in build_mobo

   **here are models****
