That's not a call, that's a URL. It's also a link to localhost, which is
*your* computer and not visible to us.
How about actually showing us the *actual call* you make? Cut and paste
the line of code that calls cmseditorlinemethod, showing the arguments.
My *guess* is that you're calling it without providing any arguments:
instance.cmseditorlinemethod()
Python automatically injects the `self` argument, but it requires two:
self and ssn:
> def cmseditorlinemethod(self, ssn):
[...]
An alternative explanation: you don't use `self` in the body of
cmseditorlinemethod. Possibly cmseditorlinemethod is actually a stand-
alone function rather than a method, and you are calling it like this:
cmseditorlinemethod(ssn)
but you have mistakenly declared the function to take two arguments.
Really, the error message is quite explicit in your problem: you have one
argument given, but two arguments are required. The only subtlety is that
for method calls, the `self` argument is automatically provided rather
than manually, but once you've learned that quirk of Python, what else do
you need to know to solve this problem?
By the way, I know this is unsolicited advice, but I'm going to give it
anyway. Look at your function:
def cmseditorlinemethod(self, ssn):
c.details = Session.query(MSPResponse).filter(
MSPResponse.beneficiaryssn == ssn).all()
content = render('/cmseditorline.mako')
return content
It looks to me like this function relies on no fewer than three global
variables, two that you read from and one which you write to:
c
Session
MSPResponse
This is almost certainly poor design. Using global state is almost always
harmful and should be avoided.
(I don't include `render` in this, as using global functions is normally
harmless.)
