Can a variable number of arguments be passed to a function?
..." % (k, v)
myfunc(abc=123, efh=456)
# abc = 123
# efh = 456
And you can mix the two:
def myfunc2(*args, **kwargs):
for a in args:
print a
for k,v in kwargs.iteritems():
print "%s = %s" % (k, v)
myfunc2(1, 2, 3, banan=123)
# 1

Testing modules in rspec
... module expects some behaviours to be present in the class into which it's mixed, then I'd try to implement dummies of those behaviours. Just enough to make the module happy to perform its duties.

I think you are mixing up contexts. How can you have two different EditorFor calls with each one getting its own size and maxlength values with the link you provided? If you don't want to use EditorFor, you always can use TextBox helper or...
