django widget radio button error save is not touch

[carlos]

Hi, i have a problem when save a field in radio button

in my models have this

CHOICES_OPTIONS = (

 (1, 'Yes'),

(2, 'No'),

)

class MyModels(...):

   myfield = models.IntegerField(choices=CHOICES_OPTIONS, null=True, blank=True)

   ....

class MyModelsForm()

   myfield = forms.ChoiceField(widget=forms.RadioSelect, choices=CHOICES_OPTIONS,

   required=False)

but when save the forms in my views this sends this error:

Field 'myfield' expected a number but got ''.

sometimes the user does not select anything neither yes nor no, the radio button they won't touch it

How can I make that null field be saved without any value and it does not throw me that error

Build your class like this one:

class Card(models.Model): 

  class Suit(models.IntegerChoices): 

  DIAMOND = 1 

  SPADE = 2 

  HEART = 3 

  CLUB = 4 

  suit = models.IntegerField(choices=Suit.choices)
