Flask: Making my first web site

[SheeppOSU]

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

[Truman]

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

[Truman]

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.

[SheeppOSU]

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

[Truman]

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.

Can anybody please help me with this error

Error:

ImportError: DLL load failed: The specified module could not be found.

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 guess I'll have to clone the whole code_snippets repository.

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