AtributeError: 'MyForm' object has no attribute 'reset_csrf'
I am getting the same error - blankData = MultiDict([ ('csrf', self.reset_csrf() ) ])
AttributeError: 'xxx' object has no attribute 'reset_csrf'
def reset(self): blankData = MultiDict([ ('csrf', self.generate_csrf_token() ) ]) self.process(blankData)
just replace "reset_csrf()" with "generate_csrf_token()" ....

I can't seem to find documentation on the reset_csrf() function. Do you know if this solution works with the current version of flask?
