python类属性没有设置?

我正在编写一个支持插件扩展的聊天机器人的奇怪问题。基本扩展类具有预定义的属性和方法,这些属性和方法将被继承并可以重载和设置。这是基类:

class Ext:
    # Info about the extension
    Name    = 'Unnamed'
    Author  = 'Nobody'
    Version = 0
    Desc    = 'This extension has no description'
    Webpage = ''

    # Determines whether the extension will automatically be on when added or not
    OnByDefault = False

    def __init__(self): 
        # Overwrite me! You can use me to load files and set attributes at startup
        raise Exception('AbstractClassError: This class must be overloaded')

    def SetName(self, name):
        name = name.split(' ')
        name = ''.join(name)
        self.Name = name

    def Load(self, file): 
        # Loads a file
        return Misc.read_obj(file)

    def Save(self, file, obj): 
        # Saves a file
        return Misc.write_obj(file, obj)

    def Activate(self, Komodo):
        # When the extension is turned on, this is called
        pass

    def add_cmd(self, Komodo, name, callback, default=False, link=''):
        # Add a command to the bot
        if name in Komodo.Ext.commands:
            Komodo.logger(msg = ">> Command '{0}' was already defined, so {1}'s version of the command couldn't be added".format(
                name, self.meta.name))
        else:
            Komodo.Ext.commands[name] = callback
            if default:
                Komodo.Ext.default_commands.append(name)
            if len(link) > 0:
                Komodo.Ext.links[name] = link

    def add_event(self, Komodo, type, callback):
        # Add an event to the bot
        if type not in Komodo.Ext.trigs:
            Komodo.logger(msg = 
                ">> Could not add '{0}' to event type '{1}' from extension '{2}' because that type does not exist".format(
                str(callback), type, self.name))
        else:
            Komodo.Ext.trigs[type].append(callback)

这是扩展通常的样子:

class Extension(Ext):
    def __init__(self, K):  
        self.file = 'Storage/Extensions/AI.txt'
        self.SetName('AI')

        self.Version = 1.1
        self.Author  = 'blazer-flamewing'
        self.Desc    = 'An extension that lets you talk to an Artificial Intelligence program online called Kato.'
        self.Webpage = 'http://botdom.com/wiki/Komodo/Extensions/AI'

        try:    self.AI = self.Load(file)
        except: self.AI = {}

    def Activate(self, K):
        print(self.Version)
        self.add_cmd(K, 'ai', self.cmd_AI, False, 'http://botdom.com/wiki/Komodo/Extensions/AI')
        self.add_event(K, 'msg', self.msg_AI)


    ...more methods down here that aren't part of the base class

每个像这样写的扩展程序都有效......除了上面提到的那个。它只在设置Name属性时成功,当读取其他属性时,它们仍然是基类的设置。在启动时,我循环遍历每个扩展以打印dict条目,实际名称,版本,作者以及扩展是否已启用并获得此结果:

Responses Responses 1.2 blazer-flamewing OFF
Ai AI 0 Nobody ON
Notes Notes 1.2 blazer-flamewing OFF
Misc Misc 1.5 blazer-flamewing OFF
System System 2.2 blazer-flamewing ON
Helloworld HelloWorld 1.3 blazer-flamewing OFF
Goodbyes Goodbyes 0 blazer-flamewing OFF
Spamfilter Spamfilter 1.2 blazer-flamewing OFF
Damn dAmn 2.2 blazer-flamewing ON
Bds BDS 0.2 blazer-flamewing OFF
Fun Fun 1.6 blazer-flamewing OFF
Welcomes Welcomes 1.5 blazer-flamewing OFF
Cursefilter Cursefilter 1.7 blazer-flamewing OFF

同样,当启用AI时,Extension.Activate()不适用于AI。我认为这与同样的问题有关(没有正确设置)

关于为什么类的属性没有设置的任何想法?我已经坚持了好几个小时,扩展设置与其他扩展程序完全相同

编辑:这是另一个比较扩展。这个实际上有效,Activate()实际调用。一切都与内容完全相同

from komodo.extension import Ext
import time

class Extension(Ext):        
    def __init__(self, K):
        self.SetName('dAmn')
        self.Version = 2.2
        self.Author  = 'blazer-flamewing'
        self.Desc    = 'Module for all standard dAmn commands such as join, part, and say.'
        self.Webpage = 'http://botdom.com/wiki/Komodo/Extensions/dAmn'
        self.OnByDefault = True

    def Activate(self, K):
        self.add_cmd(K, 'action',       self.cmd_action,       False, "http://botdom.com/wiki/Komodo/Extensions/dAmn#Me_or_Action")
        self.add_cmd(K, 'ban',          self.cmd_ban,          False, "http://botdom.com/wiki/Komodo/Extensions/dAmn#Ban_and_Unban")
        self.add_cmd(K, 'chat',         self.cmd_chat,         True,  "http://botdom.com/wiki/Komodo/Extensions/dAmn#Chat")
        self.add_cmd(K, 'demote',       self.cmd_demote,       False, "http://botdom.com/wiki/Komodo/Extensions/dAmn#Demote_and_Promote")
        self.add_cmd(K, 'join',         self.cmd_join,         False, "http://botdom.com/wiki/Komodo/Extensions/dAmn#Join_and_Part")
        ...etc

4 个答案:

答案 0 :(得分:2)

你在课堂上忘记了'自我':

try:    self.AI = self.Load(self.file)

另外,也许您的打印测试不准确。你有没有尝试过单元测试?

答案 1 :(得分:1)

SetName调用下面的块是否可能实际上缩进(例如,使用制表符而不是空格)并且以下行实际上不是__init__的一部分?

答案 2 :(得分:1)

我不认为这是你的问题,因为你得到了你想要的其他类 - 但我希望你能看到你没有在继承的类上设置任何“类”属性 - 你只是设置实例属性对他们来说(因此,如果你试图获得Extension.Version - 它将从基类“Ext”中选择属性 - 只有当你有一个扩展对象时,它的Version属性才会被实例属性“Version”覆盖。

这不包括为什么“激活”不起作用。

答案 3 :(得分:0)

我解决了自己的问题。结果我有一个扩展覆盖AI,所以它不是AI扩展本身。非常感谢你们试图提供帮助,伙计们。一个人为你所有人
