This drove me crazy for about 30 minutes.
If you’re making a heavily customized form template with Django, the newforms documentation suggests this format:
But, if you do any sort of non-field specific (form-level) validation, those validation messages won’t be returned to the user. So, instead of seeing a message like, “Both password fields must match,” the form just reloads without a explanation, confusing our poor end-users (and me for about 30 minutes)!
A quick #django IRC session later and I had the answer:
I’m no professional developer, but a lack of Google search results for this matter inspired me to make a quick post and tag it well so future Django form template customizers don’t pull their hair out.
(Sorry to post the code as images, but [hosted] WordPress doesn’t escape HTML enclosed in code blocks! Ridiculous.)
I didn’t even know IRC was still around. Nice.
Thats awesome, I never knew it before untill today. Great job. 🙂
Bit by this just this morning. Appreciate the post. I’m using Form Wizard and a custom layout to accomplish some mid wizard ajax validation. This post hit the spot on the form validation errors I was hitting.
Thanks for posting this, it helped me out 🙂
Thank you for your post.
Also documented here : http://code.djangoproject.com/browser/django/trunk/docs/ref/forms/validation.txt?rev=8511
this helped alot thanks
I am new to django .
my form renders as html code
It does not display the actual text box .
Please assist .
Thanks for the great tip. I couldn’t find this anywhere in Django’s documentation.
There is however a strange thing going on, form.non_field_errors.as_ul does add the tags (I am using Django 1.0). I used a workaround by iterating manually through the non_field_errors.
Thanks so much!
I was halfway through making a custom form and view and all sorts of mess to try and get at the __all__ errors field that the template system won’t show but contained the all-important “invalid username/password” error. Luckily your post (and shortly, a git reset) saved the day!
THANK YOU THANK YOU THANK YOU.
You are my hero!! Without this post I would have been banging my head against the wall all day!
Thanks! Just ran into the exact same issue — this was very helpful!
Thanks! This solved my problem.
