other ways to do it without using current.
in the module (ex. tools.py):
def regte_verwysing(regte, tabel, veld, db):
lys = db(db[tabel].article == regte).select(db[tabel][veld])
verwysings = [x[veld] for x in lys]
return verwysings
in the model (ex. db.py):
import tools.py
def regte_verwysing(regte, tabel, veld):
return tools.regte_verwysing(regte, tabel, veld, db)
If you like closures.
in the module (ex. tools.py):
def regte_verwysing(db):
def f(regte, tabel, veld):
lys = db(db[tabel].article == regte).select(db[tabel][veld])
verwysings = [x[veld] for x in lys]
return verwysings
return f
in the model (ex. db.py):
import tools.py
regte_verwysing = tools.regte_verwysing(db) #<- returns a callable
with args (regte, tabel, veld)
you can then call regte_verwysing(regte, tabel, veld) in your code
