"RuntimeError: working outside of application context" for config module
"RuntimeError: working outside of application context" for config module
我有一个从主文件调用的 config.py 模块，它有多种 app.configs 用于 jinja2filters 和我正在使用的一些其他插件：
config.py 的摘录：
from flask import current_app as app
#imports go here
def function1:
print("hello")
app.config['PROPERTY_1'] = 'configgoeshere'
#jinja2 functions and configs would go here like
app.jinja_env.filters['datetime'] = datetimeformat
来自 index.py 的电话：
from flask import Flask, flash, render_template, jsonify, request, json, request, redirect, url_for, Response, send_from_directory
app = Flask(__name__)
app.config['DEBUG'] = False
app.config.from_object('config') #config file
############################################################################################################################
# MAIN ROUTES
############################################################################################################################
# The route for the homepage
@app.route('/')
def index():
returns错误：
RuntimeError: working outside of application context
更新
我现在正在尝试传递应用程序上下文，这里是 index.py:
from flask import Flask, flash, render_template, jsonify, request, json, request, redirect, url_for, Response, send_from_directory
import time, datetime, os, urllib, urllib2, urlparse, requests, json, string
from urllib2 import Request, urlopen, URLError, HTTPError, urlparse
app = Flask(__name__)
app.config['DEBUG'] = False
app.config.from_object('config')
############################################################################################################################
# MAIN ROUTES
############################################################################################################################
# The route for the homepage
@app.route('/')
def index():
这是更新后的摘录 config.py：
from index import app
#imports go here
def function1:
print("hello")
app.config['PROPERTY_1'] = 'configgoeshere'
#jinja2 functions and configs would go here like
app.jinja_env.filters['datetime'] = datetimeformat
返回的错误是：
$ python index.py
Traceback (most recent call last):
File "index.py", line 8, in <module>
app.config.from_object('config')

raise RuntimeError('working outside of application context')
RuntimeError: working outside of application context
注意 - config.py 中的第 162 行没有代码，就像错误提示的那样
查看 Flask 对 Application Contexts 的解释。
在您的 config.py 文件中，from flask import current_app as app 使得对 app.config['PROPERTY_1'] = 'configgoeshere' 的调用实际上尝试在 current_app 上设置配置，尽管没有应用程序上下文默认情况下，直到收到请求（因此出现错误）。由于该调用不在函数内，因此它会在其他任何事情（如请求）发生之前立即执行。
我建议在索引中的 app 实例上进行配置，而不是在 current_app.
上进行配置
我最终使用的正是 karin 描述的内容。
index.py

app = Flask(__name__)
