从Flask中的配置更改静态文件夹 [英] Change static folder from config in Flask

问题描述

有人尝试过基于烧瓶配置的静态文件夹代码片段吗?

代码:

import flask
class MyFlask(flask.Flask):
    @property
    def static_folder(self):
        if self.config.get('STATIC_FOLDER') is not None:
            return os.path.join(self.root_path, 
                self.config.get('STATIC_FOLDER'))
    @static_folder.setter
    def static_folder(self, value):
        self.config.get('STATIC_FOLDER') = value

# Now these are equivalent:
app = Flask(__name__, static_folder='foo')

app = MyFlask(__name__)
app.config['STATIC_FOLDER'] = 'foo'

在我的情况下，抱怨此行:

In my case in complains about this line:

self.config.get('STATIC_FOLDER') = value

错误消息:Can't assign to function call

有人可以从Flask的config.py文件中设置static_folder吗?

Does anyone how to set the static_folder from the config.py file in Flask?

推荐答案

我对该代码段一无所知，但是

I don't know anything about that snippet, but

some_function(...) = some_value

永远不是有效的Python(Python没有 l值).看起来config具有类似dict的界面，所以令人反感的行可能应该只是

is never valid Python (Python doesn't have l-values). It looks like config has a dict-like interface, so the offending line should probably just be

self.config['STATIC_FOLDER'] = value

setter上方的getter定义可能存在复制和粘贴错误.

Probably a copy-and-paste error from the getter definition above the setter.
