Django formset: unicity constraint pass form_valid()
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.

Django selenium (StaticLiverServerTestCase): tests run together fail but pass if run individually
write tests with *StaticLiverServerTestCase* for my Django application. *My issue: tests runs together fail while pass when run individually.* I have read much about this behavior on SO but none of answer/comments help. It seems that issue may come from shared files/fields/data. I have tried using setUpClass/tearDownClass class methods as well as setUp/tearDown methods. Using fixture did not resolve anymore. I also tryed to make individual class for each test instead of one class with many test ethods but doesn't work anymore. My tests involve Ajax calls and I think this is related.

Django: date format management and unique_together -> “20/03/2020” value has an invalid date format. It must be in YYYY-MM-DD format.”]
Hi,
I develop a Django project with internationalization English/French
dates have to be displayed with the dd/mm/ format when user webbrowser
is FR and -mm-dd when user webbrowser is EN
to do that, I use JS that test webbrowser user favorite language and
display format accordingly
That works fine until I change my model to add *unique_together* constraint
with this date
Now, I got the error when webbrowser is in french and I try to register
date (*asp_ent_dat*)
date format "20/03/2020" is invalid. Correct format is "yyy-mm-dd".
>
>
Reading Django documentation about validation, I 'understand' that
*unique_together* is the model validation that seems to fail because of
date format
I try adding DATE_INPUT_FORMATS = ['%Y-%m-%d', '%d-%m-%Y', ] in
settings.py, the second format corresponding to the french format I need,
but it does'nt works
*I can I fix my problem:*
*Have unique_together constraint on 3 fields including asp_ent_dat and
display date in french format in my form?*
*models.py:*
class Entree(models.Model):
asp_ent_cle = models.AutoField(primary_key=True)
asp_ent_loc = models.CharField("Site concerned by the operation",
max_length=10, null=True, blank=True)
med_num = models.CharField("Trial batch number", max_length=3, null=True,

Django: how to make queries between 2 tables that are not related in the model?
Hi,
I have 2 models that are not related (maybe it should...)
I need to make a query that select all records of my table Stock WITH
related rows in Parametrage based on asp_sto_loc=asp_par_loc
Something like SQL: select * from pha_asp_sto left join pha_asp_par on
pha_asp_par.asp_par_loc=asp_sto_loc;
How can I make such a query in Django?
I have see extra() but seems to be deprecated...
Another option would be to use raw() but not recommended...
class Stock(models.Model):
asp_sto_cle = models.AutoField(primary_key=True)
asp_sto_loc = models.CharField("Site concerned", max_length=10, null=True,
blank=True)
asp_sto_pla = models.IntegerField("Quantity of placebos available",
null=True, blank=True,)
asp_sto_asp = models.IntegerField("Quantity of aspirin available",
null=True, blank=True)
class Parametrage(models.Model):
asp_par_cle = models.AutoField(primary_key=True)
asp_par_loc = models.CharField("Site concerned by settings", max_length=10,
null=True, blank=True)
asp_par_ale = models.IntegerField("Site alert value for the site",
null=True, blank=True,)
asp_par_con = models.IntegerField("Site confort value for the site",
null=True, blank=True,)
thanks for your help

form_add with pre-filled fields
Hi,
I have a models with 3 classes: Visite, Inclusion, BilanBiologique and
ExamenBiologique
- Inclusion is linked to Visite (OneToOne)
- BilanBiologique is linked to Visite (ForeignKey)

- ExamenBiologique is a subform of BilanBiologique
I use Django admin form

- have a link that redirect user to BilanBiologique

- I would like the "vis" field (which is the ForeignKey) to be pre-filled
with the corresponding value (I can retrieve this value from Inclusion)

I've read and read again the Django documentation but for now, some concept

subform, empty record is stored in the table corresponding to the subform in
the database
how to prevent this?

Problem with safedelete implementation
Hi
I am new on this forum and very, very new user of Django so hope you will
be uncensorious
I need to implement the safedelete application
(https://buildmedia.readthedocs.org/media/pdf/django-safedelete/latest/django-safedelete.pdf)
for my project but I should have miss something in the documentation
because I did non manage tu use it correctly
I will expose you briefly my problem
I have 2 classes BiologyAssessment and BiologyExam linked with a
foreignKey: a biologicalassessment is linked with multiple biologicalexam
When I delete a biologicalassessment, I want related biologicalexamn to be
'delete' (but soft delete)
When I delete a biologicalexam, I want biologicalexam to be delete (soft
delete)
I have implemented in my project but unfortunetly, when I delete a
biologicalexam, the linked biologicalasessment is also delete
I have try different to use _safedelete_policy = SOFT_DELETE for my
BiologicalExam class but it does not chage anything
could you help me ?
models.py
class BiologicalAssessment(SafeDeleteModel):
_safedelete_policy = SOFT_DELETE_CASCADE
ide = models.AutoField(primary_key=True)
vis_ref = models.ForeignKey(Visite, verbose_name='Visite',
