26:19 - "One of the biggest caveats to validators is if you programmatically call..." Thanks Justin! You saved me from wasting anymore time on this. I literally spent lots of days trying to figure out how to get custom validators work with object creation in codes. The official Python Document, Stack Overflow, and the whole wide Internet didn't point out this caveat but Justin did. Thanks again Justin! I very much appreciate all your videos!

Even though this video is from 2017, this really helps me with the form validation. Will keep it in mind.

alvinsampow

that explanation was quite enlightening. It was funny for me because many of the doubts that arose during the video were explained to me after a few seconds. excellent work.

Love your videos, so useful as it shows how to program. Most videos show the basics, but not practical in the programming world. Please keep making intermediate and advanced videos - everyone is doing 'beginner' videos.

This was the best explanation on validators i found on youtube!

georgesmith

97% of what you said I didn't understand! Yet again, today is the first time I've heard of validators.
The learning search continues...!

Hi Justin, a quick question, nothing to related to this video though.
I am developing a web page, where the user uploaded images are modified using PIL, and stored in the directory with the original image uploaded (in media_cdn). I want to show this algorithm-generated image to users. But I cant find a way to display this image.

Please respond, i am really stuck here.

Thanks for the amazing tutorials Justin, I just picked up Django 3 months ago and your tutorials helped out a lot :D. If you don't mind could you do a short tutorial to show how ManytoMany with through models work?

Good morning a question how could I validate that a field is unique in the form since it does not use models ? Thanks

juanmejia

Thank you for sharing, this validation way makes it much easier to dev

satorikomeiji

how can i load a form after checking if the values are in the database for the form fields of that modelform, and then view that partially parially filled form to the user to post the remaining fields which were not in database
