Hi,
I've post my issue on Stackoverflow and do not have any ansewer so far.
Hope some Django dev could me here ;)
I try using FBV (logic more easy to understand for me).
Maybe I should have used inlineformset_facory to deal with FK but for
conception concerns patient is passed in context.
I faced many issues I've tried to solved but it is more "hack" and I would
like to find a proper way to do the same:
1.
empty_forms was submitted and create a record in database; normally,
default formset behavior is not to submit empty formset I manage this case
using condition form.cleaned_data != {}. It is maybe cause
2.
I define unique_together in my model Traitement. But it seems this is
not manage by Django in form validation. When submitting a form with
duplicates, IntegrityError is raised. I manage this case using a try-catch
bloc. I also tried to define a form validation with clean() method in
TraitementForm but doesn't seems to works.
3.
With traitement_create() code below, all errors can not be displayed at
the same time: forma validation will be displayed but not the
IntegretyError if any.
I have read many documentation and tutorial but could not find answer.
Don't know how I can post code here so I attached txt doc with part of my
code.
Jérôme
