Show objects properly as choices in django forms choicefield - django

Question

I am working on some kind of testing application. I have two models for tests and users answers:
class TestModel(AbstractDatetimeModel):
number = models.IntegerField(unique=True)
answer_1 = models.CharField(max_length=255)
answer_2 = models.CharField(max_length=255)
class AnswerModel(AbstractDatetimeModel):
ANSWERS = (
('1', 'A'),
('2', 'B')
)
candidate = models.ForeignKey(User)
question = models.ForeignKey(TestModel)
answer = models.CharField(max_length=1, choices=ANSWERS)
And I have a form, where candidate (user) can answer each question. To implement this I use a view formset_factory:
def communicative_test(request):
questions = TestModel.objects.all()
question_formset = formset_factory(form=TestForm, extra=questions.count())
question_formset = question_formset(initial=[{'candidate': request.user, 'question': x.number,
'answer_1': x.answer_1, 'answer_2': x.answer_2} for x in questions])
return render(request, 'testing/communicative.html', locals())
On a form I need to show ChoiceField, where choices should be data from fields answer_1 and answer_2. Here is this form:
class TestForm(forms.ModelForm):
answer_1 = forms.CharField()
answer_2 = forms.CharField()
VARIANTS = (
('answer_1', answer_1),
('answer_2', answer_2)
)
variants = forms.ChoiceField(choices=VARIANTS, widget=forms.RadioSelect())
class Meta:
model = TestAnswer
fields = '__all__'
Problem is that on a page these answers displays as radio buttons with following labels:
<django.forms.fields.CharField object at 0x7f36248ef5d0>
<django.forms.fields.CharField object at 0x7f36248ef650>
I need to display it properly.

Answer 1

Well, as #Anentropic mentioned, I was not on the right way.
And he is right, because I need to submit only answer A or B. But for user on the form I need to display text for these answers from Test model. So I wrote two templatetags for this.
class TestForm(forms.ModelForm):
class Meta:
model = TestAnswer
fields = '__all__'
def communicative_test(request):
questions = TestModel.objects.all()
QuestionFormSet = formset_factory(form=TestForm, max_num=questions.count())
formset = QuestionFormSet(initial=[{'candidate': request.user, 'question': x.number} for x in questions])
return render(request, 'testing/communicative.html', locals())
Two custom templatetags for each answer (A/B):
#register.filter(name='get_answer1')
def get_answer1(question):
try:
question = TestModel.objects.get(number=question)
answer = question.answer_1
except ObjectDoesNotExist:
answer = ''
return answer
#register.filter(name='get_answer2')
def get_answer2(question):
try:
question = TestModel.objects.get(number=question)
answer = question.answer_2
except ObjectDoesNotExist:
answer = ''
return answer
And template is:
{% load test_tags %}
<form id="communicative-test-form" method="post">
{% csrf_token %}
{{ question_formset.management_form }}
{% for form in question_formset.forms %}
{% crispy form %}
{{ form.id }}
<p>{{ form.question.value }}</p>
<p><label>
<input type=radio name="form-{{ form.question.value|add:"-1" }}-answer" id='id_form-{{ form.question.value|add:"-1" }}-answer' value="1">
{{ form.question.value|get_answer1 }}
</label></p>
<p><label>
<input type=radio name="form-{{ form.question.value|add:"-1" }}-answer" id='id_form-{{ form.question.value|add:"-1" }}-answer' value="2">
{{ form.question.value|get_answer2 }}
</label></p>
{% endfor %}
<div style="text-align: right;" class="col-md-12">
<button type="submit">Save</button>
</div>
</form>
