Flask在移动app.py和static文件夹后无法解析静态文件 [英] Flask unable to resolve static files after moving app.py and static folder
问题描述
我正在打包Flask应用程序，并且在将app.py迁移到ship_comm模块中后，即使我在更改root_folder时正在使用新的模板路径，也无法解析静态URL.这是我的结构:
I am packaging up my Flask app and I am unable to resolve static URLs after migrating the app.py into the module ship_comm even though it is picking up the new templates path when I change the root_folder. Here is my structure:
├── README.md
├── requirements.txt
├── setup.py
└── ship_comm
├── app.py
├── config.py
├── database.py
├── db_models.py
├── devices.py
├── replay.py
├── router.py
├── routing.db
├── static
│ ├── css
│ │ └── main.css
│ └── img
│ ├── captain-ai-logo-small.png
│ ├── captain-ai-logo-square.png
│ ├── favicon.ico
│ └── screenshot.png
└── templates
├── devices.html
├── home.html
├── layout.html
├── messages.html
├── new_route.html
├── new_serial.html
├── new_udp.html
└── routes.html
这是我对Flask应用程序的初始化
And here is my initialization of the Flask app
app = Flask(__ name__，root_path ='ship_comm')
这解决了我与TemplateNotFound错误的问题，但是仍然无法找到静态文件夹，即使它应该能够在root_path中找到它也正确吗?我曾尝试明确声明 static_folder ='ship_comm/static'和 static_folder ='static'，但这也无济于事.
This fixed my issue with TemplateNotFound error, but still it's not able to find the static folder, even though it should be able to find it in the root_path right? I have tried explicitly stating static_folder='ship_comm/static' and static_folder='static' but that also didn't help.
我使用 python -m ship_comm.app
这是我的layout.html，现在缺少徽标:
Here is my layout.html that is now missing the logo:
<!doctype html lang="en">
<link rel="shortcut icon" href="{{ url_for('static', filename='img/favicon.ico') }}">
<title>Ship Comm Router</title>

推荐答案
root_path 应该是自动计算的.如果要设置它，请尝试使用绝对路径(假设您在 app.py :
root_path should be automaticaly calculated. If you want to set it, try to use absolute path (assuming you create the app in app.py:
import os
dir_path = os.path.dirname(os.path.realpath(__file__))
app = Flask(__name__, root_path=dir_path)
那么您的静态文件应该可以工作了.
Then your static files should be working.
