ValueError: day is out of range for month
[02/Feb/2021 13:53:33] "GET /admin/main/vergadering/ HTTP/1.1" 500 133973

this is my model

class Vergadering(models.Model):
    kriskras = models.ForeignKey(Kriskras, on_delete=models.CASCADE)
    date = models.DateField(("Date"), default=datetime.date.today)
    extra = models.CharField(max_length=5)
    activiteit = models.CharField(max_length=500)

    def __str__(self):
        return self.activiteit
    

this is my html page

      {% for vergadering in ls.vergadering_set.all %}
            <div class="input-group mb-3">
                <input type="date", value="{{vergadering.date}}"  class="form-control col-2" name="d{{vergadering.id}}">
                <input type="text", value="{{vergadering}}" class="form-control" name="c{{vergadering.id}}">
            </div>
            
            
        {% endfor %}

and this is my view

def index(response, id):
    ls = Kriskras.objects.get(id=id)
    
    if response.method == "POST":
        print(response.POST)
        if response.POST.get("wijzig"):
            print("wijzig")
            for vergadering in ls.vergadering_set.all():
                    pass
                    

        elif response.POST.get("newVergadering"):
            txt = response.POST.get("new")
            date = response.POST.get("newdate")

            if len(txt) > 2:
                ls.vergadering_set.create(activiteit=txt, date=date)
            else:
                print("invalid")

    return render(response, "main/kriskras.html", {"ls":ls})

i cant figure out why this is raising, i think it has something to do with the date format?

Answer

try this

class Vergadering(models.Model):
    kriskras = models.ForeignKey(Kriskras, on_delete=models.CASCADE)
    date = models.DateField(("Date"), default=datetime.date.today()) # 


>>> import datetime
>>> datetime.date.today
<built-in method today of type object at 0x9e14e0>
>>> datetime.date.today()
datetime.date(2021, 2, 2)
