Django does not add attribute to the custom ModelForm widget

Question

models.py

class MyModel(models.Model):
    pub_date = models.DateTimeField(default=timezone.now)
    title = models.CharField(max_length=255, blank=False, null=         


        

Answer 1

The widgets option is for overriding the defaults. It doesn't work for your tos field because you have declared tos = BooleanField() in your form. See the note in the widgets docs for more information about this.

You can fix the issue by passing widget when you declare the tos field:

class MyModelForm(ModelForm):
    tos = BooleanField(widget=CheckboxInput(attrs={'data-validation-error-msg': 'You have to agree to our terms and conditions'}))
    class Meta:
        model = models.MyModel
        fields = ['title', 'text', 'tos']
        widgets = {
            'title': TextInput(attrs={'class': 'form-control', 'placeholder': 'Title'}),
            'text': Textarea(attrs={'class': 'form-control', 'placeholder': 'Text'}),
        }
