I use MultipleChoiceField in form. It shows me REQUIREMENTS_CHOICES list with checkboxes where user can select and add new requirements to database. Is it possible to disable checkboxes (in my case requirements) which is already in the database? Lets say I have A and C in database so I dont need them.
First value in tulpe is symbol of requirement, second value is the name of requirement.
models.py:
class Requirement(models.Model):
code = models.UUIDField(_('Code'), primary_key=True, default=uuid.uuid4, editable=False)
symbol = models.CharField(_('Symbol'), max_length=250)
name = models.CharField(_('Name'), max_length=250)
forms.py:
REQUIREMENTS_CHOICES = (
('A', 'Name A'),
('B', 'Name B'),
('C', 'Name C'),
('D', 'Name D'),
)
class RequirementAddForm(forms.ModelForm):
symbol = forms.MultipleChoiceField(required=False, widget=forms.CheckboxSelectMultiple, choices=REQUIREMENTS_CHOICES,)
class Meta:
model = Requirement
fields = ('symbol',)
views.py:
def requirement_add(request):
data = dict()
if request.method == 'POST':
form = RequirementAddForm(request.POST)
if form.is_valid():
list = dict(REQUIREMENTS_CHOICES) # {'C': 'Name C', 'A': 'Name A', 'B': 'Name B'}
symbols = form.cleaned_data.get('symbol') # ['A', 'B', 'C']
requirement = form.save(commit=False)
for symbol in symbols:
requirement.symbol = symbol
requirement.name = list[symbol]
requirement.save()
data['form_is_valid'] = True
requirements = Requirement.objects.filter()
context = {requirement': requirement, 'requirements': requirements}
data['html_requirement'] = render_to_string('project/requirement_list.html', context)
else:
data['form_is_valid'] = False
else:
form = RequirementAddForm()
context = {'form': form}
data['html_requirement_form'] = render_to_string('project/requirement_add.html', context, request=request)
return JsonResponse(data)
