如何从Flask中的配置文件导入？

I have followed the layout of my Flask project from http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world.

我从http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world上了解了我的Flask项目的布局。

I have the following structure:

我有以下结构:

app/
    __init__.py
    views.py
    forms.py
    myFile.py
run.py
config.py

In views.py, forms.py I am able to use

在views.py中,我可以使用forms.py

from config import basedir

However I cannot use that in myFile.py

但是我不能在myFile.py中使用它

I added

import Flask

and when I modify it, the Flask web server restarts, but it doesn't say found changes in app/myFile.py restarting it just restarts.

当我修改它时,Flask Web服务器重新启动,但它没有说app / myFile.py中发现的更改重新启动它只是重新启动。

What do I need to do to be able to use

我需要做什么才能使用

from config import basedir

in my python file. I don't see anything special being done in __init__.py for forms.py.

在我的python文件中。我没有看到在__init__.py中为forms.py做了什么特别的事情。

EDIT: This is my __init__.py file:

编辑:这是我的__init__.py文件:

from flask import Flask
from config import basedir

app = Flask(__name__)
app.config.from_object('config')
from app import views

When people talk about configs in Flask, they are generally talking about loading values into the app's configuration. In your above example you could have something like app.config.from_object('config') in your init.py file. Then all the configuration values will be loaded into the app.config dictionary.

当人们谈论Flask中的配置时,他们通常都在谈论将值加载到应用程序的配置中。在上面的示例中,您可以在init.py文件中使用app.config.from_object('config')。然后,所有配置值都将加载到app.config字典中。

Then in any of your files you could just import the app object to gain access to that dictionary. I tend to access that app object by doing from flask import current_app as app then just app.config['MY_SETTING'] to get the value I care about. Read up more in the documenation.

然后在您的任何文件中,您只需导入应用程序对象即可访问该字典。我倾向于通过使用flask import current_app作为app然后只是app.config ['MY_SETTING']来访问该app对象,以获得我关心的值。阅读文档中的更多内容。

After a little bit of fiddling (and a little help from the 'net), I could improve this further, by changing the code to include the config to:

经过一点点摆弄(以及来自'net的一点帮助)后,我可以通过更改代码以包含配置来进一步改进这一点:

app.config.from_object('config.ProductionConfig')

This enables this cool pattern for configurations:

这为配置提供了这种酷炫的模式:

class Config(object):
    DEBUG = True
    DEVELOPMENT = True
    SECRET_KEY = 'do-i-really-need-this'
    FLASK_HTPASSWD_PATH = '/secret/.htpasswd'
    FLASK_SECRET = SECRET_KEY
    DB_HOST = 'database' # a docker link

class ProductionConfig(Config):
    DEVELOPMENT = False
    DEBUG = False
    DB_HOST = 'my.production.database' # not a docker link

What's left now is to see how to integrate testing configs into this, but at least it feels less clumsy.

现在剩下的就是看看如何将测试配置集成到这里,但至少它感觉不那么笨拙。
