Django: keep data visible in multiple individual forms - django

Question

I have three forms in three tabs respectively in a template.
I fill in the first tab, submit, fill in the second form, submit, fill in the third form, submit.
Is there a way to keep the data in each form after saving? I need to show them all together.
No, when I save the second form I lose my data on the first form.
input.html: template
<form class="tab-pane fade in active" id="demographics" method="post" >
<input type="hidden" name="form_id" value="demographics">
{%crispy frm%}
</form>
<form class="tab-pane fade" id="diagnosis" method="post">
<input type="hidden" name="form_id" value="diagnosis">
{%crispy frm_d%}
</form>
<form class="tab-pane fade" id="a_b_sickle" method="post">
<input type="hidden" name="form_id" value="a_b_sickle">
{%crispy frm_a_b_s%}
</form>
views.py
def input(request):
context = RequestContext(request)
if request.method == 'POST':
submitted = request.POST.get('form_id', '')
print submitted
if submitted == 'demographics':
# Get the Form1 instance
my_demographics = DemographicForm(request.POST)
#my_diagnosis = DiagnosisForm()
if my_demographics.is_valid():
my_demographics_object= my_demographics.save()
my_diagnosis=DiagnosisForm({'patient': my_demographics_object.patient_id, 'diagnosis_option': 'b-thalassaemia syndromes'})
my_a_b_sickle=A_b_sickle_thalForm({'patient': my_demographics_object.patient_id})
else:
my_diagnosis=DiagnosisForm()
my_a_b_sickle = A_b_sickle_thalForm()
elif submitted == 'diagnosis':
my_diagnosis = DiagnosisForm(request.POST)
my_demographics = DemographicForm()
my_a_b_sickle = A_b_sickle_thalForm()
if my_diagnosis.is_valid():
my_diagnosis_object=my_diagnosis.save()
my_a_b_sickle =A_b_sickle_thalForm({'patient': my_diagnosis_object.patient})
else:
my_demographics = DemographicForm()
my_a_b_sickle = A_b_sickle_thalForm()
elif submitted == 'a_b_sickle':
my_a_b_sickle = A_b_sickle_thalForm(request.POST)
my_demographics = DemographicForm()
my_diagnosis = DiagnosisForm()
if my_a_b_sickle.is_valid():
my_a_b_sickle.save()
else:
raise ValueError('No form specified !')
else:
my_demographics = DemographicForm()
my_diagnosis = DiagnosisForm()
my_a_b_sickle= A_b_sickle_thalForm()
return render(request,'input.html', {'frm':my_demographics, 'frm_d': my_diagnosis, 'frm_a_b_s': my_a_b_sickle})
Any ideas please?

Answer 1

You can either submit them using ajax or send them back filled in your context. If you can get the saved objects between request by any association they have you can try:
For the second way you can try something like this:
my_demographics = DemographicForm(my_demographic_object)
my_diagnosis = DiagnosisForm(my_diagnosis_object)
my_a_b_sickle= A_b_sickle_thalForm(my_a_b_sickle)
return render(request,'input.html', {'frm':my_demographics, 'frm_d': my_diagnosis, 'frm_a_b_s': my_a_b_sickle})
In fact, with that you can even make that work as an update form with a little extra using the 'instance' attribute of ModelForm.
