Join my free course on the basics of Flask-SQLAlchemy: prettyprinted.com/flasksql

Man people can build a whole web app just by watching this channel keep it up.

Dude you make such amazing videos! I am a self taught programmer and your explanations are so clearly laid out and thorough I 100% appreciate it. I am working on my first webapp now with Flask and I have made so much progress thanks to you. Thank you again and keep on making great vids!

Wow, this was one of the most straight forward tutorials ever! Thank you so much!

Amazing video! Your style of teaching is great! Easy to understand, quick, and to the point. Thank you so much!

I don't speak much english but I want say to u THANK U VERY VERY MUCH! Your tutorials are useful for me!

Thank you! This video helped me a lot! I was stuck on Email sending for a while: I was using Gmail and found out that "Less secure app access" was no longer available, so I switched to Zoho email and it finally worked well.

Your are really good at what you do. This helped me integrate email validation with my flask python. Without the usual rabbit hole of issues that I run into. I really appreciate the video. Keep up the great work!

I learn a lot with your content. Great job!

You made me stuck into Flask, not Php and CodeIgnite anymore. thanks.

You made my day! Thanks

Once again a helpful video. Thank you. I ran in some difficulties, because I used views in my project and encountered the circular import problem. With current_app.app_context() I managed to get the sending of the mails working.

A very clear tutorial on a useful topic

Thank you for making this video

Very useful video! Thanks!

itsdangerous is a very good module for validating tokens but there is one major problem. As long as the token has not expired the user can validate the token over and over again. Let me give you an example. Suppose you create a token that expires in 24 hours, as long as the token is less than 24 hours old the user is able to validate the link over and over again which is not what you want. You want them to use it only once and then if they did click on it again nothing happens, maybe you can have a message stating that you have already used the token. The way I get around it is to create a field in the database called token. When I issue the token to a user I store that token in the database after the user has validated their token I set that field to none. Now when the user clicks on the token the database is called before itsdangerous function if the field is none a message displays saying to the user that there is no token to validate.

Hey Anthony, quality content as usual! I actually implemented this during the weekend, could have used your video then, but luckily I managed anyway! As a follow-up question, since I couldn't find a way to expire the token manually when a link has been clicked, I set up a table for each token which I then set to used=True after a token has been used successfully. My gut tells me it would be cleaner to completely delete the token from the DB when it's been used, but then I can't come up with a solution how to tell if it's been used unless I actually query the database instead of comparing the token from the UrlSerializer of course... Come to think of it. Anyway! So far, so good. But I was wondering if a token could actually be generated identically twice, because that could eventually become an issue with password-resets etc for my current solution (just setting the token to used). Again, many thanks for your videos!

Great one.

Thank you

Thank you for this! I have a question, is there a way to make this link only clickable once. Like a onetime link?

Thanks a lot!!

You're awesome :) Tutorial request: CRUD app with Flask + Vue JS 2 + Redis, please.

thanks! very useful ! ! !

ERROR: smtplib.SMTPNotSupportedError: STARTTLS extension not supported by server. (all data from mail server i put in code, but not works)

Hi may I have the configuration for gmail? Thanks :)

Please also make video on password reset email and also tell what is the difference between UrlSafeTimedSerializer and TimedJSONWebSignatureSerializer of itsdangerous package

how can i get mail server for my gmail?

Can I add this to my Flask Log-In app???

I tried sending mail with this statement command MAIL_USE_TLS=False but its not working. After removing this statement I'm able to send mails without any errors.

I am facing ' NameError: name 'SignatureExpired' is not defined ' during try except SignatureExpired

error a rah yeh how to solve werkzeug.routing.BuildError: Could not build url for endpoint 'confirm_email' with values ['token']. Did you mean 'contact' instead?

Hay your cheat sheet have some mistake in jason response u directly import jsonify but it is from flask import jsonify this cause lot of problem to me to figure out the error in my program and waste my time too please correct it

Thank you for the video! Unfortunately the link with the code returns 404, can you fix it? Thank you again!

thanks

I am sorry, but how to get the name/IP address and the port of your mail id (to type in the configuration file)? Or should we create an account? Did not get that part. Can you (or someone) please tell me what exactly to type in the config.py file and where to get the details ('cause I am getting a Connection Refused error)?

you said something about sharing the link for email configuration... can't see it

when it hits the confirm email link, how do you associate that with a user? basically how should one look up a user based on the url with just a token?

The following type of error is showing, could you please help me out? and How can we find out mail server name? TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

Hi, what if I put the flask-webapp onto an actual server? I put it on AWS EC2, configured with nginx, and it runs inernally at 127.0.0.1:8000 so the confirmation email link is still starts with local address 127.0.0.0.. :(

Is it safe to use the same logic to generate a link for users to reset their password?

hey guys i am a beginner but can u tell me from where can i get all the mail configuration settings of mine? thanks in advance

Hi i am a beginner can you solve me this error socket.gaierror socket.gaierror: [Errno -2] Name or service not known at the end it says socket.gaierror: [Errno -2] Name or service not known
