Form valid error caused by DateTimeField auto_now_add=True

Using Django
1

When creating a new record it fails at the form.is_valid(): bcuz of DateTimeField(auto_now_add=True). I do
not know how to deal with this. Cannot find anything in Djangoproject or the forum.

  • This field is required.
models.py (partial)

class ToLog(models.Model)
	date_time = models.DateTimeField(auto_now_add=True)

views.py (partial)

def create_turn(request): 
    if request.method == "POST":
        form = ToLogForm(request.POST)
        if form.is_valid():
            tologs = ToLog.objects.create(
                social_title= form.cleaned_data.get('social_title'),
               
            )
			form.save()	

forms.py (partial)

class ToLogForm(forms.ModelForm):
    
    date_time = forms.DateTimeField()
    completed = forms.BooleanField(required=False) # widget = forms.CheckboxInput(attrs={'class': 'form-control'})
    entrytype = forms.ChoiceField(choices=[[1, 'Control_M'],[2, 'SolarWinds'],[3, 'FYI'],[4, 'Other'],[5, 'Adhoc']],
                                  widget = forms.Select(attrs={'class': 'form-control'}))  #label = "Entrytype") # choices=EntryType.choices, blank=True, null=True)    
     #validation
    def clean(self):
        super(ToLogForm, self).clean()
        social_title = self.cleaned_data.get('social_title')
        
        
        if len(social_title)<4:
            self.add_error('title','Can not save social_title less than 4 characters long')
            self.fields['social_title'].widget.attrs.update({'class': 'form-control  is-invalid'})

        return self.cleaned_data
            
    class Meta:
        model = ToLog
        fields = '__all__'

That date_time field with auto_now_add should not be a field in your form. Change your fields attribute to not include it.

See the docs for auto_now_add to see the effects of having this field in the form.

auto_now_add and auto_add contains editable = False.

Hi Ken,
Yes, I ended up excluding in from the form and works good now.
Thank you for helping me.
