Hi,
I develop a Django project with internationalization English/French
dates have to be displayed with the dd/mm/yyyy format when user webbrowser
is FR and yyyy-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,
blank=True,)
asp_ent_dat = models.DateField("Entry date", null=True, blank=True)
asp_ent_pro_pay = models.CharField("Country of treatment origin in case of
entry", max_length=10, null=True, blank=True)
asp_ent_pro_sit = models.CharField("Processing source site in case of
entry", max_length=10, null=True, blank=True)
opr_nom = models.CharField("Input operator", max_length=10, null=True,
blank=True)
opr_dat = models.DateField("Entry date", null=True, blank=True)
log = HistoricalRecords()
class Meta:
db_table = 'pha_asp_ent'
verbose_name_plural = 'Entries'
ordering = ['asp_ent_cle']
unique_together = ['asp_ent_loc','med_num','asp_ent_dat']
*JS:*
$(function(){
if(window.navigator.language == 'fr-FR' | window.navigator.language ==
'fr'){
$("#id_asp_ent_dat").datepicker(
{
dateFormat: 'dd/mm/yy',
}
);
}
else
{
$("#id_asp_ent_dat").datepicker(
{
dateFormat: 'yy-mm-dd',
}
);});
