Hi, the method is correct, in the sense that CLEANUP() actually
removes leading and trailing space.
You should use .strip() only if you need to "preserve" special
characters in the field. Actually CLEANUP removes any special
character and newlines from the field (it applies the regex "[^ \n\w]"
and then remove all the matching items).
PS: It's easy to test out validators: just go to the shell and then:
- CLEANUP()('hello world!')
- CLEANUP()(' hi this is going to be stripped ')
- CLEANUP()('£uk3 $k1Walker')
and watch for the first element of the tuple (the second one contains
the errors usually but CLEANUP validator don't return them)
- ('hello world', None) #the ! has been removed
- ('hi this is going to be stripped', None) # leading and trailing
space removed
- ('uk3 k1Walker', None) # $ and £ removed
