Error : Django 'ChoiceField' object has no attribute 'use_required_attribute'

Question

Here’s my model (in models.py)

class Score(models.Model):

    ROUTINETYPE_CHOICE = (
        (0, 'R1'),
        (1, 'R2'),
        (2, 'F'),
    )

    routineType = models.IntegerField(choices=ROUTINETYPE_CHOICE)
    pointA = models.DecimalField(max_digits=3, decimal_places=1)
    pointB = models.DecimalField(max_digits=3, decimal_places=1)
    pointC = models.DecimalField(max_digits=5, decimal_places=3)

And here’s my Form (in forms.py)

class ScoreForm(forms.ModelForm):

    class Meta:
        ROUTINETYPE_CHOICE = (
            (0, 'R1'),
            (1, 'R2'),
            (2, 'F'),
        )

        model = Score
        fields = ('routineType', 'pointA', 'pointB', 'pointC')

        widgets = {
            'routineType': forms.ChoiceField(choices=ROUTINETYPE_CHOICE),
            'pointA': forms.TextInput(attrs={'placeholder': 'xx,xx', 'value': '0'}),
            'pointB': forms.TextInput(attrs={'placeholder': 'xx,xx', 'value': '0'}),
            'pointC': forms.TextInput(attrs={'placeholder': 'xx,xx', 'value': '0'}),
        }

And my view is usual:

def score_create(request):

    if request.method == 'POST':
        form = ScoreForm(request.POST)

        if form.is_valid():
            form.save()
            return HttpResponseRedirect('/score/')

    else:
        form = ScoreForm()

    context = {'form': form}
    return render(request, 'score_create.html', context)

When I try to display my form, django give me this error:

'ChoiceField' object has no attribute 'use_required_attribute'

The use_required_attribute is new in Django 1.10 and I’ve the possibility to set it to False. But it’s on the Form level, it will say that my other fields are loosing the HTML required attribute too.

I’ve only three possibilities (with no “dummy” default option selected, like “choose…”), so my ChoiceField have always an option selected and then the HTML attribute “required” is fulfilled.

Someone know an another solution (other than set use_required_attribute=False) ?

Answer 1

Thank Daniel. It was not a very detailed answer but, you’r right.

widgets = {
    'routineType': forms.Select(attrs={'class': 'form-control col-sm-2'}),
    'pointA': forms.TextInput(attrs={'class': 'form-control col-sm-2', 'placeholder': 'xx,xx', 'value': '0'}),
    'pointB': forms.TextInput(attrs={'class': 'form-control col-sm-2', 'placeholder': 'xx,xx', 'value': '0'}),
    'pointC': forms.TextInput(attrs={'class': 'form-control col-sm-2', 'placeholder': 'xx,xx', 'value': '0'}),
    }

And it’s works !

For anybody still wondering, there is an alternative to using models.IntegerField with choices argument and forms.Select inside widgets: forms.ChoiceField has to be moved from Meta class constructor to ScoreForm class constructor.

So the code will be along the lines of

class Score(models.Model):

    routineType = models.IntegerField()
    pointA = models.DecimalField(max_digits=3, decimal_places=1)
    pointB = models.DecimalField(max_digits=3, decimal_places=1)
    pointC = models.DecimalField(max_digits=5, decimal_places=3)


class ScoreForm(forms.ModelForm):

    ROUTINETYPE_CHOICE = (
        (0, 'R1'),
        (1, 'R2'),
        (2, 'F'),
    )
    routineType = forms.ChoiceField(choices=ROUTINETYPE_CHOICE)

    class Meta:

        model = Score
        fields = ('routineType', 'pointA', 'pointB', 'pointC')

        widgets = {
            'pointA': forms.TextInput(attrs={'placeholder': 'xx,xx', 'value': '0'}),
            'pointB': forms.TextInput(attrs={'placeholder': 'xx,xx', 'value': '0'}),
            'pointC': forms.TextInput(attrs={'placeholder': 'xx,xx', 'value': '0'}),
        }
