Issue 2437 The example flaskr can't easily be run by a beginner in Flask framework https://github.com/pallets/flask/issues/2437
Issue Summary
Ran into the above error because some files are put into the wrong directory and need to be moved.Proposed solution
Better understanding of the tutorial folder structure. Here's a better diagram than the original.
flaskr/
├── MANIFEST.in
├── flaskr
│ ├── __init__.py
│ ├── flaskr.py
│ ├── schema.sql
│ ├── static
│ └── templates
└── setup.py
The indentation of the original tutorial is hard to read!
after a successful $flask run command
you will get this updated folder structure below:
flaskr/
├── MANIFEST.in
├── flaskr
│ ├── __init__.py
│ ├── __init__.pyc
│ ├── flaskr.py
│ ├── flaskr.pyc
│ ├── schema.sql
│ ├── static
│ └── templates
├── flaskr.egg-info
│ ├── PKG-INFO
│ ├── SOURCES.txt
│ ├── dependency_links.txt
│ ├── requires.txt
│ └── top_level.txt
└── setup.py
happy coding.
Background:
I found the Flaskr tutorial through Nicole White's talk about Neo4j and Flaskr. Plus Flask is a popular python web framework. I have always wanted to code a helloworld.
