I don't remember exactly but you might have to type "string" rather than "str"

Correct. Wondering why is standard 'str' not set.

By the way, the author of the course mentioned that he added this json with posts
https://github.com/CoreyMSchafer/code_sn...posts.json
Could anyone tell me how to actually add it? Never had any business with json.

I think this is what you're looking for - https://realpython.com/python-json/

I created a list json_data ( had to use raw github link )

import requests
import json

raw_json = requests.get("https://raw.githubusercontent.com/CoreyMSchafer/code_snippets/master/Python/Flask_Blog/snippets/posts.json")
json_data = json.loads(raw_json.content)

now just to figure out where to put this. Huh

Can anybody please help me with this error

The mess started when I decided to change the name of my root folder from 'Environments' to more suitable 'Projects'. So now I have Projects/Flask_blog and within Flask_blog have run.py and flaskblog subfolder with all the code for the web site.

now ran run.py again and got this:

You have not set to SQLALCHEMY_TRACK_MODIFICATIONS to False as you metion before in post.
Add line 2.

app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite://site.db'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False

Just clone from GitHub as Corery has all step in blog tutorial there.

I added app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False but it didn't give me desired outcome. Still the same problem. I guess I'll have to clone the whole code_snippets repository.
Thank you.

After cloning to my project folder starting run.py and trying to open a web site leads to this error

Error:
AttributeError: 'NoneType' object has no attribute 'drivername'

I told in in post #2 about DownGit or cooler GitZip where can download individual files and folder.
