Suppress warning Eclipse when developing with Pydev

Question

I want to suppress Eclipse warnings when defining decorators.

For example:

def tool_wrapper(func):
   def inner(self):
      cmd="test"
      cmd+=func(self)
   return inner

@tool_wrapper
def list_peer(self):
   return "testing "

I get warning on a decorator definition: "Method 'tool_wrapper' should have self as first parameter

I define the decorator inside a class, so this is the only way it's working properly.

Thanks

Answer 1

Just define your decorator outside the class and pass the instance as an argument, it will work just as fine.

def tool_wrapper(func):
    def inner(inst):  # inst : instance of the object
        cmd="test"
        cmd+=func(inst)
        return cmd
    return inner


class Test():

    def __init__(self):
        pass

    @tool_wrapper
    def list_peer(self):
        return "testing "


if __name__ == '__main__':
    t = Test()
    print t.list_peer()

This script prints testtesting
