问题

I am converting a survey from a Form to a ModelForm in Django 1.6.2.

Can anyone tell me what is the equal of forms.ChoiceField(widget=forms.Select(), and forms.ChoiceField(widget=forms.RadioSelect() using ModelForm?

I have tried widget=models.Select() or widget=models.RadioSelect() but it keeps giving the error

AttributeError: 'module' object has no attribute 'Select'

AttributeError: 'module' object has no attribute 'RadioSelect'

Old Code

forms.py

class SurveyFormB(forms.Form): 

    #Do you own a Smartphone?   
    YES_SMARTPHONE = 'Yes'
    NO_SMARTPHONE = 'No'    

    SMART_PHONE_OWNERSHIP = (
        (YES_SMARTPHONE, 'Yes'),
        (NO_SMARTPHONE, 'No'),
               )    
    smart_phone_ownership = forms.ChoiceField(widget=forms.RadioSelect(), choices=SMART_PHONE_OWNERSHIP, initial= "", label='Do you own a Smartphone?', required = False)


    #If 'Yes' How many hours a day do you access the Internet on it?
    SMART_PHONE_LESS_THAN_ONE_HOUR_A_DAY = 'Less than one hour  day'
    SMART_PHONE_ONE_TO_TWO_HOURS_A_DAY = '1 - 2 Hours a day'
    SMART_PHONE_TWO_TO_FOUR_HOURS_A_DAY = '2 - 4 hours a day'
    SMART_PHONE_FOUR_TO_SIX_HOURS_A_DAY = '4 - 6 hours a day'
    SMART_PHONE_SIX_TO_EIGHT_HOURS_A_DAY = '6 - 8 hours a day'
    SMART_PHONE_EIGHT_PLUS_HOURS_A_DAY = '8 + hours a day'


    SMART_PHONE_USAGE = (
        ("", "----------"),
        (SMART_PHONE_LESS_THAN_ONE_HOUR_A_DAY, 'Less than one hour a day'),
        (SMART_PHONE_ONE_TO_TWO_HOURS_A_DAY, '1 - 2 Hours a day'),
        (SMART_PHONE_TWO_TO_FOUR_HOURS_A_DAY, '2 - 4 hours a day'),
        (SMART_PHONE_FOUR_TO_SIX_HOURS_A_DAY, '4 - 6 hours a Day'),
        (SMART_PHONE_SIX_TO_EIGHT_HOURS_A_DAY, '6 - 8 hours a day'),
        (SMART_PHONE_EIGHT_PLUS_HOURS_A_DAY, '8 + hours a day'),
               )

    smart_phone_usage = forms.ChoiceField(widget=forms.Select(), choices=SMART_PHONE_USAGE, initial= "", label='If Yes, How many hours a day do you access the Internet on it?', required = False)

New Code (not working)

modules.py

#Do you own a Smartphone?   
    YES_SMARTPHONE = 'Yes'
    NO_SMARTPHONE = 'No'


    SMART_PHONE_OWNERSHIP = (
        (YES_SMARTPHONE, 'Yes'),
        (NO_SMARTPHONE, 'No'),
               )    
    smart_phone_ownership = models.CharField(null=True, max_length=1, widget=models.RadioSelect(), choices=SMART_PHONE_OWNERSHIP, verbose_name='Do you own a Smartphone?')



#If 'Yes' How many hours a day do you access the Internet on it?
    SMART_PHONE_LESS_THAN_ONE_HOUR_A_DAY = 'Less than one hour  day'
    SMART_PHONE_ONE_TO_TWO_HOURS_A_DAY = '1 - 2 Hours a day'
    SMART_PHONE_TWO_TO_FOUR_HOURS_A_DAY = '2 - 4 hours a day'
    SMART_PHONE_FOUR_TO_SIX_HOURS_A_DAY = '4 - 6 hours a day'
    SMART_PHONE_SIX_TO_EIGHT_HOURS_A_DAY = '6 - 8 hours a day'
    SMART_PHONE_EIGHT_PLUS_HOURS_A_DAY = '8 + hours a day'


    SMART_PHONE_USAGE = (
        (SMART_PHONE_LESS_THAN_ONE_HOUR_A_DAY, 'Less than one hour a day'),
        (SMART_PHONE_ONE_TO_TWO_HOURS_A_DAY, '1 - 2 Hours a day'),
        (SMART_PHONE_TWO_TO_FOUR_HOURS_A_DAY, '2 - 4 hours a day'),
        (SMART_PHONE_FOUR_TO_SIX_HOURS_A_DAY, '4 - 6 hours a Day'),
        (SMART_PHONE_SIX_TO_EIGHT_HOURS_A_DAY, '6 - 8 hours a day'),
        (SMART_PHONE_EIGHT_PLUS_HOURS_A_DAY, '8 + hours a day'),
               )

    smart_phone_usage = models.CharField(null=True, blank=True, max_length=1, widget=models.Select(), choices=SMART_PHONE_USAGE, verbose_name='If Yes, How many hours a day do you access the Internet on it?')

I have also tried overwriting it in the forms.py as was necessary for SelectDateWidget but did not get it

Any help is as always much appreciated

Thanks

Django model doesn’t provide RadioSelect or Select widget. You need to add this in Model form.

forms.py

class SmartPhoneForm(forms.ModelForm):
    class Meta:
        model = Phone
        fields = ['smart_phone_ownership', 'smart_phone_usage']
        widgets = {
            'smart_phone_ownership': forms.RadioSelect,
            'smart_phone_usage': forms.Select,
        }

models.py

class SmartPhone(models.Model):
    # Do you own a Smartphone?
    YES_SMARTPHONE = 'Yes'
    NO_SMARTPHONE = 'No'


    SMART_PHONE_OWNERSHIP = (
        (YES_SMARTPHONE, 'Yes'),
        (NO_SMARTPHONE, 'No'),
               )    
    smart_phone_ownership = models.CharField(
        null=True, max_length=1,
        default=None, 
        choices=SMART_PHONE_OWNERSHIP, verbose_name='Do you own a Smartphone?')



#If 'Yes' How many hours a day do you access the Internet on it?
    SMART_PHONE_LESS_THAN_ONE_HOUR_A_DAY = 'Less than one hour  day'
    SMART_PHONE_ONE_TO_TWO_HOURS_A_DAY = '1 - 2 Hours a day'
    SMART_PHONE_TWO_TO_FOUR_HOURS_A_DAY = '2 - 4 hours a day'
    SMART_PHONE_FOUR_TO_SIX_HOURS_A_DAY = '4 - 6 hours a day'
    SMART_PHONE_SIX_TO_EIGHT_HOURS_A_DAY = '6 - 8 hours a day'
    SMART_PHONE_EIGHT_PLUS_HOURS_A_DAY = '8 + hours a day'


    SMART_PHONE_USAGE = (
        (SMART_PHONE_LESS_THAN_ONE_HOUR_A_DAY, 'Less than one hour a day'),
        (SMART_PHONE_ONE_TO_TWO_HOURS_A_DAY, '1 - 2 Hours a day'),
        (SMART_PHONE_TWO_TO_FOUR_HOURS_A_DAY, '2 - 4 hours a day'),
        (SMART_PHONE_FOUR_TO_SIX_HOURS_A_DAY, '4 - 6 hours a Day'),
        (SMART_PHONE_SIX_TO_EIGHT_HOURS_A_DAY, '6 - 8 hours a day'),
        (SMART_PHONE_EIGHT_PLUS_HOURS_A_DAY, '8 + hours a day'),
               )

    smart_phone_usage = models.CharField(
        null=True, blank=True, max_length=1,
        choices=SMART_PHONE_USAGE,
        # default=None,
        verbose_name='If Yes, How many hours a day do you access the Internet on it?'
        )
