Hi,
i'm trying to figure out how to implement sorting into the DataGrid using
MongoDB with ming.
Basically i took the example in the DataGrid documentation and tried to
change it for Ming.
ordering = kw.get('ordercol')
if ordering and ordering[0] == '+':
places = places.sort(ordering[1:], ming.DESCENDING) # Descending
elif ordering and ordering[0] == '-':
places = places.sort(ordering[1:], ming.ASCENDING) # Ascending
But for some reason it doesn't work. It crashes with the following error
message:
TypeError: must use keyword argument for key function
I also tried to enter the keyword instead of "ordering[1:]", but i get the
same error. Any idea what's wrong?
