Question

我在模板中分别在三个标签中有三个表单。

我填写第一个标签，提交，填写第二个表格，提交，填写第三个表格，提交。

有没有办法在保存后保留每个表单中的数据？我需要一起展示它们。

不，当我保存第二张表格时，我会丢失第一张表格上的数据。

input.html ：模板

<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})

有什么想法吗？

您可以使用ajax提交它们，也可以在上下文中填写它们。如果您可以通过任何关联在请求之间获取保存的对象，您可以尝试：

对于第二种方式，你可以尝试这样的事情：

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})

事实上，通过这种方式，您甚至可以使用＆＃39;实例＆＃39;作为更新表单。 ModelForm的属性。
