使用来自“user"的 pyCharm 进行重构到“self.user" [英] Refactor with pyCharm from "user" to "self.user"

问题描述

我想将变量从局部范围移动到对象级别.新代码应该像以前一样使用 self.user 而不是 user :

I want to move a variable from local scope to object level. The new code should use self.user and not user like before:

class Foo(object):
    def test_foo(self):
        user=User()
        ...
        user.do()

新代码应如下所示:

class Foo(object):
    def test_foo(self):
        self.user=User() # I can remove this line by hand
        ...
        self.user.do()

我尝试重构>>重命名从 user 到 self.user 但 pyCharm 说:插入的标识符无效"

I tried to refactor>>rename from user to self.user but pyCharm says: "Inserted identifier is not valid"

如何使用 pyCharm 重构它?

How can I refactor this with pyCharm?

推荐答案

您要做的不是简单的重命名，而是创建一个新的实例属性.因此，您应该使用 Extract > Field 菜单项，而不是使用 Rename.或者，您可以通过 Ctrl+Alt+F 访问此重构(这取决于您选择的快捷方式.我的是 KDE 的默认设置).

What you are trying to do is not a simple rename, but creating a new instance attribute. As such, instead of using Rename you should use Extract > Field menu item. Alternatively you can access this refactoring as Ctrl+Alt+F (this depends on the shortcuts you have chosen. Mine is the default for KDE).
