django date input format is not interpreted properly

Question

I am trying to setup a Model and a corresponding ModelForm with django containing a DateField/Input.

from django.db import models

class MyModel(models.Model):
    myDate = models.DateField()

from django import forms

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = "__all__"
        widgets = {
            'myDate': forms.DateInput(format=("%d/%m/%Y")) 
        }

But sadly, when I enter a date in the form that results out of MyModelForm, the day and the month get exchanged. E.g. 1/2/22 will result in January 2nd 2022 instead of feburary 1st 2022. What else do I need to do, so the date gets interpreted properly?

Answer 1

Specifying the format only in your widget’s form is just used as a display, you still need to pass it to specify the field myDate as a DateField in your form:

from django.db import models

class MyModel(models.Model):
    myDate = models.DateField()

from django import forms

class MyModelForm(forms.ModelForm):
    myDate = forms.DateField(input_formats=["%d/%m/%Y"])

    class Meta:
        model = MyModel
        fields = "__all__"
        widgets = {
            'myDate': forms.DateInput(format=("%d/%m/%Y")) 
        }

Another option to set this up would be to add the format inside the DATE_INPUT_FORMAT variable in settings.py. See https://docs.djangoproject.com/en/4.0/ref/settings/#date-input-formats for more
