Python coding question

I have been playing with some extensions to the apcupsd plugin and in one case, I want to call an existing method that expects an Indigo action and device object. If I log an action received from Indigo, using

indigo.server.log('Received action: \n%s\n' % (action))

I get:

delayAmount : 900
description : plugin action
deviceId : 145579207
pluginId : com.berkinet.apcupsd
pluginTypeId : apcupsdServerEvent
props : com.berkinet.apcupsd : (dict)

actionType : commok (string)
replaceExisting : True
textToSpeak :

Now, I have added a class to create my own action object with just the fields I need for my method. The method processes the object just fine. But, when I attempt to log the object, I get

<__main__.Action object at 0xfd1c710>

I was just wondering why Indigo's object can be interpreted by a %s and mine can't?

For reference, here is the class that creates the object:

Code: Select all

class Action(object):
    def __init__(self):
        self.deviceId = 1
        self.actionType = None
        self.pluginTypeId = 'apcupsdServerEvent'
        self.props = {'actionType': 'commok'}

And here is where I actually create my object:

Code: Select all

action = Action()
action.deviceId = 145579207
action.pluginTypeId = 'apcupsdServerEvent'
action.props['actionType'] = event
action.pluginTypeId = 'apcupsdServerEvent'

Indigo python objects define the __str__ method to inspect the object (and return it as a string). You could do something similar with your Indigo action facade object. FYI, internally we are using the dir() function to inspect the object (to build the string inside __str__).

Thanks Matt, That was it.

For others who may have the same question here is my code. Warning: this is probably not the most pythonista approach, and is probably not very extensible, plus lots of other caveats. But, IWFM*

Code: Select all

class Action(object):
    def __init__(self):
        self.deviceId = None
        self.pluginTypeId = None
        self.props = {'actionType': None}
    def __str__(self):
        desc_str = "deviceId: %s \npluginTypeId: %s \nprops: %s \n" %(self.deviceId, self.pluginTypeId, self.props)
        return desc_str

and called by:

Code: Select all

        action = Action()
        action.deviceId = 145579207
        action.pluginTypeId = 'apcupsdServerEvent'
        action.props['actionType'] = event

* It Works For Me
