Redefine html properties in widget

[Denis Makarov]

Hello!

I have my own ModelForm with widgets in Meta class.

class Meta:

 model = Foods

 fields = '__all__'

 widgets = {

 'quantity': NumberInput(attrs={'min': 1, 'max': 10, 'name': "quantity2"}),

 'comment': TextInput(),

 }

My quantity field have NumberInput as standard.

I want to redefine html properties such name and min value.

But when I did this (code above), my fiend quantity have old values (name and min value). Max value correct.

<p><label for="id_quantity">Quantity:</label> <input id="id_quantity" max="10" min="0" name="quantity" type="number" value="1" /></p>

Django (1.9.4)

What's wrong?

Some attributes such as IntegerField.min_value need to be customized on the field rather than the widget. This will ensure that validation is also done server-side. (see https://github.com/django/django/blob/f3595b25496691966d4ff858a3b395735ad85a6e/django/forms/fields.py#L278-L285 for example)

On the server-side I use validators for controlling valid values.

But if I use TextInput, such:

'quantity': TextInput(attrs={'min': 1}),

It works fine in html source code.

Full source code you can find below:

class Foods(models.Model):

        def __str__(self):

                return self.name

        name = models.CharField(max_length=200)

        quantity = models.PositiveSmallIntegerField(default=1, validators=[

        MinValueValidator(1)])

        quandesc = models.CharField(max_length=3, choices=(('Item', 'Qty'),

        ('Kilo', 'Kg.'), ('Litr', 'L.')), default='Item')

        comment = models.TextField(blank=True)

        to_ods = models.BooleanField(default=False)

        to_email = models.BooleanField(default=False)

        foodlist = models.ManyToManyField('FoodList')

class FoodForm(ModelForm):

        class Meta:

                model = Foods

                fields = '__all__'

                widgets = {

                        'quantity': NumberInput(attrs={'min': 1}),

                        'comment': TextInput(),

                }

Can you write me simple example how I must use min. value for html form?
