Python WSGI + Flask render_template-500内部服务器错误? [英] Python WSGI + Flask render_template - 500 Internal Server Error?
问题描述
我有这个结构,
index.py
run.py
app/
__init__.py
routes.py
templates/
...
index.py,
import os
import sys
activate_this = os.path.dirname(__file__) + '/venv/Scripts/activate_this.py'
exec(open(activate_this).read(), dict(__file__ = activate_this))
# Expand Python classes path with your app's path.
sys.path.insert(0, os.path.dirname(__file__))
from run import app
#Initialize WSGI app object.
application = app
run.py,
from flask import Flask
app = Flask(__name__)
from app import routes
if __name__ == '__main__':
app.run()
app/routes.py,
app/routes.py,
from run import app
from flask import Flask, render_template
@app.route('/')
def hello_world():
return 'Hello World'
@app.route('/dave')
def myDave():
return 'Hello World - From Dave'
@app.route('/home')
def home():
return render_template('home.html')
@app.route('/about')
def about():
return render_template('about.html')
app/__init__.py
,
(blank)
因此,当我使用/
访问应用程序时,会得到Hello World
这是正确的,而/dave
我会得到Hello World - From Dave
So when I access the app with /
I get Hello World
which is correct, and /dave
I get Hello World - From Dave
但是使用/home
和/about
时,出现 500 Internal Server Error
日志文件根本没有提供有关该错误的太多信息,
The log file does not give much info about the error at all,

但是,似乎Flask中的模块render_template
未加载或无法正常工作.
But it seems that the module render_template
from Flask is not loaded or not working.
有什么主意我做错了吗?
Any ideas what have I done wrong?
推荐答案
Flask默认位于应用程序根目录下的"templates"文件夹中.
Flask defaults to a 'templates' folder at the root path of the application.
鉴于您现有的设置,您可以在run.py
中实例化您的Flask应用程序:
Given your existing setup, you can instantiate your Flask app like this in run.py
:
project_root = os.path.dirname(__file__)
template_path = os.path.join(project_root, 'app/templates')
app = Flask(__name__, template_folder=template_path)
