VSCode Python/Pylance 扩展未在引用中列出方法的动态使用

Question

问题描述

当我使用 Pylance 作为 Python 语言服务器时，它不会向我显示使用这些方法的参考。

我将 TestClass1 对象传递给 TestClass2 对象。

如果我要转到classes1.py 文件并点击“查找所有引用”，我只是获取该文件内的引用（这是方法的定义）。

src/folder1/classes1.py:

class TestClass1():
    def __init__(self, word):
        self.word = word
        
    def print(self):
        print(f"Word: {self.word}")

src/folder2/classes2.py：

class TestClass2:
    def __init__(self, printer):
        self.printer = printer

    def testprint(self):
        self.printer.print()
        

main.py：

from src.folder1.classes1 import TestClass1
from src.folder2.classes2 import TestClass2

printer = TestClass1("Hello World")
def main():
    test = TestClass2(printer)
    test.testprint()

if __name__ == "__main__":
    main()

所有文件路径均相对于项目文件夹。

当我切换到绝地语言服务器时，它工作得很好。但另一方面，绝地武士并不是真正可用，因为我在尝试重命名符号时遇到错误。在将代码重构为新符号名称的每个文件中，它只是在代码之间添加新行。

我使用了一些设置，但无论我操作哪个设置，都不起作用。

{
    "python.languageServer": "Pylance",
    "python.analysis.autoImportCompletions": true,
    "python.analysis.typeCheckingMode": "basic"
}

Answer 1

我收到了 Pylance Devs 的回复：

Pylance 将 TestClass2 中的 self.printer.print() 调用显示为 引用 TestClass1.print() 您需要告诉它打印机 应该始终是通过类型注释的 TestClass1 的实例。 例如：

class TestClass2:
    def __init__(self, printer: TestClass1):

如果没有这个，Pylance 会将打印机视为 Any 类型。它不假设 这只是因为您对 TestClass2() 的唯一调用传递了一个 TestClass1对象，因此只能初始化TestClass2 通过传入 TestClass1 对象。

因此这不是一个错误，而是设计使然。
