Hi Folks,
First time posting on here so if I violate any laws, please forgive me. I
also posted the same question
<http://stackoverflow.com/questions/29858678/reading-checkbox-in-django>on
StackOverflow but didn't get any answers so I'm hoping this place will get
more attention.
I'm having a hard time reading whether the checkbox is checked or not. I
created a formset with just the first_name and last_name since my initial
page is only asking for those 2 information. Once entered and validated,
the next page will show a checkbox next to the duplicate names.
Here are the things that I've tried:
- Changed the checkbox's name to iterate with the for-loop for
uniqueness. (Regardless if I check the box or not, the results are always
the same {'overwrite': False}.)
- Added the Boolean value with the first_name & last_name formset
(Result - 'ManagementForm data is missing or has been tampered with')
I think the problem lies with obtaining the 'POST' data. Any help is much
appreciated.
