thank you for the great tutorial! there're couple questions if anyone can please help, I accidentally added a task without any content, it worked, thought since in class Todo() content=(nullable=False), it shouldn't let me do that, right? also changed db.String(200) to db.String(5) to test it out, but it let me add text more than 5 characters, why? thank you again in advance!

Thanks. This helped to get me started!

Hey all, I was having difficulty with my CSS not loading even after I updated it. The solution is to hard refresh because for some reason flask will save your style settings with caching. Try CTRL-Shift-R and hopefully that can solve your issue as well. 🙂

How can i run an infinite loop in the background? I want to be able to manipulate it via the flask server but with threading either flask isnt starting the server or my loop doesnt works …

Anyone got the code for the CSS page? In the video the top section was cut off and my page doesn't have the same style as in the tutorial

can you create tutorial on simple user management system in flask something like this ————————-
I have the following tables:
Table name= group Attributes:
id name
Here simply the group is created.
——————————————————————————
Table name = group permission
Attributes: id group_id Permission_id
Here simply the permission for the group is assigned
—————————————————————————–
Table name =permission
Attributes: id name code name
Here permission is created Table name =user Attributes: id username password
——————————————————————————-
Here the user is created
Table name =user_groups
Attributes: Id User_id Group_id
Here the group for the user is assigned and all the permission inside this group should also be assigned to that user
————————————————————————————————————————–
Table name =user_permission
Attributes: Id User_id Permission_id
Here the user might get more permission other than the permission assigned from the group.
For example, if the user has only access for reading and writes from it’s defined group then if the admin user wants then he/she can directly assign permission to access a certain menu to the specific user without assigning to the other user of the same group.
I haven't seen anyone on youtube have done this stuff

Really good tutorial. I am a beginner in flask and I must say the lecture is really insightful covering all the topics in one go.
Vaishali Chouhan
Really Useful. I created an app which is running successfully in my local but getting below error while running from heroku:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
Let me know if you are familiar with this.
Jacob Moore
Code: from app import db | Error: can't read /var/mail/app

Holy cow! This has been a lifesaver. I got about a quarter way through Cory Schafer's flask series and was completely lost. It's a bit hard to tell the essentials apart from stylistic design choices and I just felt like I was struggling to memorize huge chunks of code. This tutorial is way more bare bones; but that's a great advantage it has over other tutorials as I'm really getting the no-nonsense core ideas about flask out of this. Great stuff!
MusicJunkie
Struggling with this tutorial as someone who's new to Flask. He doesn't explain any of these steps and is just kind of messing about – going back and forth and figuring out an app by himself. Maybe it's entertaining to watch if you're already familiar with this stuff, but it does nothing for a beginner.
Suraj Oberai
while adding a new task , even if we leave the input field "content" empty , the task is added with empty string.Maybe "nullable=False" is not working. Could you suggest some other validation, please?
Rizal Widyananda
Why not just use
From flask import * ?
Josh Nahamkes
