Question

i have a checkbox button called 'hof' in a form, if i click the checkbox in the form and sends, it works but if i uncheck it refuses to send, what i get is This field is required.

here is my model

class CreateSingleSigner(models.Model):
 firstname = models.CharField(max_length = 32)
 middlename = models.CharField(max_length = 32)
 lastname = models.CharField(max_length = 32)
 displayname = models.CharField(max_length = 32)
 era = models.CharField(max_length = 11)
 category = models.CharField(max_length = 32)
 hof = models.BooleanField()
 externallink = models.CharField(max_length = 70)
 loaprice = models.FloatField(max_length = 10)
 basiccertprice = models.FloatField(max_length = 10)
 appraisalcost = models.FloatField(max_length = 10)
 notability = models.CharField(max_length = 32)

Here if my VIEWS

def singlesigner(request):
 context = {}
 if request.method == 'POST':
 createsinglesigner_form = CreateSingleSignerForm(data=request.POST)
 if createsinglesigner_form.is_valid():
 createsinglesigner = createsinglesigner_form.save(commit=False)
 createsinglesigner.firstname = request.POST['firstname']
 createsinglesigner.middlename = request.POST['middlename']
 createsinglesigner.lastname = request.POST['lastname']
 createsinglesigner.displayname = request.POST['displayname']
 createsinglesigner.era = request.POST['era']
 createsinglesigner.category = request.POST['category']
 createsinglesigner.hof = request.POST['hof']
 createsinglesigner.externallink = request.POST['externallink']
 createsinglesigner.loaprice = request.POST['loaprice']
 createsinglesigner.basiccertprice = request.POST['basiccertprice']
 createsinglesigner.appraisalcost = request.POST['appraisalcost']
 createsinglesigner.notability = request.POST['notability']
 createsinglesigner_form.save()
 else:
 print createsinglesigner_form.errors
 else:
 # context['createsinglesigner'] = CreateSingleSigner()
 createsinglesigner_form =CreateSingleSignerForm()
 return render(request, "signer/singlesigner.html", {"createsinglesigner_form":createsinglesigner_form})

Here is my Form

class CreateSingleSignerForm(forms.ModelForm):
 firstname = forms.CharField(max_length = 32, required = True, help_text = "firstname")
 middlename = forms.CharField(max_length = 32, required = True, help_text = "middlename")
 lastname = forms.CharField(max_length = 32, required = True, help_text = "lastname")
 displayname = forms.CharField(max_length = 32, required = True, help_text = "displayname")
 era = forms.CharField(max_length = 11, required = True, help_text = "era")
 category = forms.CharField(required = True, help_text = 'category')
 hof = forms.BooleanField(required=False, help_text = 'hall of fame')
 notability = forms.CharField(max_length = 11, required = True, help_text = 'notability')
 externallink = forms.CharField(required = True, help_text = "externallink")
 loaprice = forms.FloatField(required = True, help_text = "loaprice $")
 basiccertprice = forms.FloatField(help_text = "basiccertprice $")
 appraisalcost = forms.FloatField(help_text = "appraisalcost $")
 class Meta:
 model = CreateSingleSigner
 fields = ('firstname',)

Answer 1

Try to change in form

hof = forms.BooleanField(required=False, help_text = 'hall of fame')

to

hof = forms.BooleanField(initial=False, required=False, help_text = 'hall of fame')

• uche: Still getting This field is required for the checkbox
• uche: MultiValueDictKeyError at /signer/singlesigner/ "'hof'"
• zablotski: try to change your view to: if createsinglesigner_form.is_valid(): createsinglesigner_form.save() else: print createsinglesigner_form.errors

Answer 2

You shouldn't be setting an initial value for the BooleanField on your form.

You are also using a ModelForm, it's not necessary to rewrite the logic of your model in the form.

forms.py:

class CreateSingleSignerForm(forms.ModelForm):
 class Meta:
 model = CreateSingleSigner
 fields = (
 'hof',
 ...
 )
 # Instantiate the object and override the required setting on hof field:
 def __init__(self, *args, **kwargs):
 super(CreateSingleSignerForm, self).__init__(*args, **kwargs)
 self.fields['hof'].required = True

If you would like to stick to your code, then inherit from forms.Form instead of forms.ModelForm and instruct Django to save the unchecked state of the checkbox:

hof = forms.BooleanField(required=True, help_text='Hall of Fame')

It's also good practice to set a default value for hof in your models.py for legibility.
