Pydev 不会解析动态创建的属性
你好,
我有一个奇怪的问题,我似乎无法解决:
我正在 Windows XP 上使用 pydev 插件和 eclipse Helios(如果有的话)。
我有一个包含类的模块。此类的 __init__ 接受一个参数,该参数确定此类的方法应具有的属性集。
由于我不允许显示实际代码,所以我可以给出以下类比:
class Car:
def __init__(self, attrs):
# attrs is a dictionary.
# the keys of attrs are the names of attributes that this car should have
# for example, a key of attr could be 'tires'
# the values of attrs are the values of the attributes which are the keys
# so if the key is 'tires', it's value might be 4
现在,由于我在运行时动态设置这些变量,因此当我这样做时,Pydev 无法给我建议:
c = Car()
print c.tires
当我输入“c. ” +,pydev 不提供轮胎作为建议。
我该如何获得此功能?或者说这只是 pydev 目前无法做到的事情?
我将不胜感激任何帮助
Greetings SO,
I have a weird problem that I don't seem to be able to solve:
I am working with the pydev plugin with eclipse Helios on Windows XP (if it matters).
I have a module which contains a class. The __init__
of this class takes a parameter which determines the set of attributes that a method of this class should have.
Since I am not allowed to show actual code, I can give the following analogy:
class Car:
def __init__(self, attrs):
# attrs is a dictionary.
# the keys of attrs are the names of attributes that this car should have
# for example, a key of attr could be 'tires'
# the values of attrs are the values of the attributes which are the keys
# so if the key is 'tires', it's value might be 4
Now, since I'm setting these variables dynamically at runtime, Pydev is not able to give me suggestions when I do this:
c = Car()
print c.tires
When I type in "c." +, pydev does not offer tires as a suggestion.
How might I go about getting this functionality? Or is it just not something that pydev can do at present?
I'd appreciate any help

这是所有动态语言 IDE 都会遇到的普遍问题。如果不执行您的代码,Pydev 无法知道 Car.__init__ 为 Car 实例设置了哪些属性。如果您使用类变量作为您在 __init__ 中设置的属性,Pydev 应该能够提供自动完成建议。
This is a general problem which all dynamic language IDEs suffer. Pydev has no way of knowing what attributes
Car.__init__
sets on instances of Car, without executing your code. If you use class variables for the attributes you set in__init__
, Pydev should be able to offer autocomplete suggstion.为 Imran 的解决方案+1。但是,我想到了一个更好的解决方案:
这样,虽然在自动完成中仍然建议所有属性的超集,但内存并没有浪费。
+1 to Imran for his solution. But, Ia better solution occurred to me:
This way, ene though the superset of all attributes is still suggested in the autocomplete, memory is not wasted.
