Example Code

# parse selections and generate a lookup query
        for sel in selection:
            if sel[1] and not sel[1] == "all":
                name = sel[0].replace("sel_", "")
                val = sel[1]
                if name == "customer":
                    query = query.filter(Xconnect.customer == int(val))
                if name == "region":
                    query = query.filter(Xconnect.region == int(val))
                if name == "lvc":
                    query = query.filter(Xconnect.lvc == str(val))
                if name == "id":
                    query = query.filter(Xconnect.id == int(val))
                if name == "conn_status":
                    query = query.filter(Xconnect.conn_status == int(val))
                if name == "environment":
                    query = query.filter(Xconnect.environment == int(val))
                if name == "client_type":
                    query = query.filter(Xconnect.client_type == int(val))
                if name == "vendor":
                    query = query.filter(Xconnect.vendor == int(val))
                if name == "comp_id":
                    query = query.filter(Xconnect.comp_id == int(val))

Description

Hello, I have a select field to search for DB records based on some fields, table is called Xconnect,

how do I translate a lookup string into a SQLModel object w/o using constant If/Then blocks?

is there a better way to do this than explicit if/then statements?

for example if someone searches Xconnect table where client_type == "abc"

how can I translate this into a SQL model query w/o using explicit if/then mapping, ie

              if name == "client_type":
                    query = query.filter(Xconnect.client_type == int(val))
