python - How do I decorate Fabric tasks with @roles when my tasks inherit from the Task class?

Question

I have a number of tasks defined as Task subclasses and I have roledefs set similar to the following:

env.roledefs = { "web": ["1.2.3.4"], "db": ["5.6.7.8"] }

class Foo(Task):
  name = "foo"

  def run(self):
    pass

foo = Foo()

With the @roles decorator I can decorate tasks if they are functions in a module but I'm not sure how to apply this to Task classes. Decorating the class or its run function doesn't seem to work.

I'm using Fabric 1.4.0

认为您应该能够像这样使用 init ：

def __init__(self):
     env.roles = ['web']

或使用执行：

execute(foo, roles='web')
