Django sets a default value to model input

When I load the page, the value of the input is automaticly this:

How is that possible?

views file

    if request.method == 'POST':
        form = FieldForm(request.POST, instance=Field(user=request.user))
        if form.is_valid():
            obj = form.save(commit=False)
            obj.creator_adress = get_client_ip(request)
            obj.save()
            return redirect('/dashboard')
    else:
        form = FieldForm(instance=Field)
    
    ......

forms file

class FieldForm(forms.ModelForm):
    class Meta:
        model = Field

        fields = (
            'title',
            'url'
        )

models file

class Field(models.Model):
    user = models.ForeignKey(
        settings.AUTH_USER_MODEL,
        default=None,
        null=True,
        on_delete=models.CASCADE,
    )
    title = models.CharField(max_length=255)
    url = models.CharField(max_length=255)
    creator_adress = models.GenericIPAddressField(null=True)

    def __str__(self):
        return str(self.user)

Here one input 😂
value= <django.db.models.query_utils.DeferredAttribute object at 0x000001E180304250>

>Solution :

In your view you are passing a reference to your Field model as the argument instance. Doing this places the representation of the model fields into your form fields when it is rendered. If what you are wanting is just a blank form when you load the page then just remove the instance argument and create your form in your else statment, like form = FieldForm(). The instance argument is only needed for a form if you are trying to pre-populate data into the form, for example if you made a view where you wanted to update information on an already created object you would pass an instance of your model to the instance argument.
