Re: [Zope] Sorting Zope objects in python scripts
Hi Ron, it's not clear to me if you want to dynamically give the property on which to sort or if this can be static.
Oliver: As it turned out, it was a static property (attribute).
I don't know how to do the first in an elegant way, but here is the second:
def compare_integers(a,b): return cmp(a.element_number, b.element_number)
myList.sort(compare_integers)
That did the trick. Your help is greatly appreciated. Thanks! Ron
i.e. you handle the objects to your custom compare method and it gets the attribute it wants to compare from the objects.
Oh, and if the object itself knows on what it wants to be sorted, you could use
def compare_integers(a,b): return cmp(getattr(a,a.what_to_sort), getattr(b,b.what_to_sort))
i.e. a.what_to_sort would be a string property holding the name of the property on which a and b want to be sorted. You could also use some global variable which you set in your script, and your compare method would retrive it.
HTH, oliver
