I have created one custom user registration form in Django as follows:
class RegistrationForm(UserCreationForm):
state = forms.ModelChoiceField(State.objects.all())
booth = forms.ModelChoiceField(Booth.objects.none())
first_name = forms.RegexField(regex=r'^\w+$', widget=forms.TextInput(attrs=dict(required=True, max_length=30)), label=_("First name"), error_messages={ 'invalid': _("This value must contain only letters") })
last_name = forms.RegexField(regex=r'^\w+$', widget=forms.TextInput(attrs=dict(required=True, max_length=30)), label=_("Last name"), error_messages={ 'invalid': _("This value must contain only letters") })
password1 = forms.CharField(widget=forms.PasswordInput(attrs=dict(required=True, max_length=30, render_value=False)), label=_("Password"))
password2 = forms.CharField(widget=forms.PasswordInput(attrs=dict(required=True, max_length=30, render_value=False)), label=_("Password (again)"))
date_of_birth = forms.DateField(widget=forms.TextInput(attrs= {'class':'datepicker'}))
sex = forms.ChoiceField(choices=(('M', 'MALE'), ('F', 'FEMALE')), label=_("Sex"))
voter_id = forms.CharField(widget=forms.TextInput(attrs=dict(required=True, max_length=30)), label=_("Voter Id"))
is_election_staff = forms.BooleanField(initial=False, required=False)
class Meta:
model = CustomUser
fields = ['state', 'booth', 'first_name', 'last_name', 'voter_id', 'date_of_birth', 'sex', 'is_election_staff']
Then in register.html I am populating dropdownlist for booth based on state she selects as follows:
$(document).ready(function() {
$('.datepicker').datepicker();
$('#id_state').on('change', function() {
alert(this.value );
$.ajax({
url: '/voting/api/booths/',
dataType: 'json',
type: 'GET',
data: {state_id : $('#id_state').val()},
success: function(data) {
$('#id_booth').empty();
for (row in data) {
$('#id_booth').append($('<option></option>').attr('value', data[row].id).text(data[row].name));
}
}
});
});
});
But the problem is that while submitting the form I am getting the following error message in UI:
Select a valid choice. That choice is not one of the available choices
Can please anyone suggest me what mistake I am doing here.
EDIT: In my views.py for handling registation form submission:
@csrf_protect
def register(request):
if request.method == 'POST':
form = RegistrationForm(request.POST)
pdb.set_trace()
if form.is_valid():
print "In register request = "+ str(request.POST)
form.save()
return HttpResponseRedirect('/voting/register/success/')
else:
form = RegistrationForm()
variables = RequestContext(request, {
'form': form
})
return render_to_response(
'registration/register.html',
variables,
)
Here in above view function I have checked form.is_valid() which is returning false. Can please anyone suggest me what mistake I am doing.
Booth value should be in queryset which you pass to the field - Booth.objects.none()
- Now it's always empty.
You can dynamically change this queryset, something like this:
class RegistrationForm(UserCreationForm):
# your fields here
def __init__(self, *args, **kwargs):
super(RegistrationForm, self).__init__(*args, **kwargs)
# check state in POST data and change qs
if 'state' in self.data:
self.fields['booth'].queryset = Booth.objects.filter(state_id=self.data.get('state'))
