Question

我想从form2向我的数据库插入多行。以下是我的代码

首先是model.py

class DataPribadiSiswa(models.Model):
   SiswaID = models.AutoField(primary_key=True)
   WaliKelasID=models.CharField(max_length=5,blank=True,null=True)

第二个model.py

class RiwayatSekolah(models.Model):
   SekolahID=models.AutoField(primary_key=True)
   SiswaID_FK=models.ForeignKey(DataPribadiSiswa,blank=True, null=True)
   SekolahNama=models.CharField(max_length=50,blank=True,null=True)
   SekolahThMasuk=models.CharField(max_length=4,blank=True,null=True)
   SekolahThKeluar=models.CharField(max_length=4,blank=True,null=True)
   SekolahKet=models.TextField(blank=True,null=True)

views.py

def tambah_siswa(request):
   form = datasiswa(request.POST)
   form2 = riwayatsekolah(request.POST)
   FormSet2 = inlineformset_factory(DataPribadiSiswa, RiwayatSekolah, extra=2, fields=('SekolahID','SiswaID_FK','SekolahNama','SekolahThMasuk','SekolahThKeluar','SekolahKet'))
   if request.method == 'POST':
       if form.is_valid():
           siswa_instance = form.save()
           form2 = FormSet2(request.POST, instance=siswa_instance)
           if form2.is_valid():
               form2.save()
           return redirect('index')
   else:
       formall={}
       formall['form'] = datasiswa()
       formall['form2'] = riwayatsekolah()
   return render(request, 'siswa/tambah_siswa.html', formall)

这是我的模板

<form action="" method="post">
{% csrf_token %}
<table >
    {{ form2.management_form }}
    {{ form2.as_table }}
</table>
</form>

如何将form2中的多行插入数据库？当我运行此代码时，它只插入一行。

为了简化对相关对象的处理，您可以使用Inline formsets

您可以这样实现：

from django.forms import inlineformset_factory
FormSet2 = inlineformset_factory(DataPribadiSiswa, RiwayatSekolah, extra=2)

现在查看试试这个：

def tambah_siswa(request):
    form = datasiswa(request.POST or None)
    FormSet2 = inlineformset_factory(DataPribadiSiswa, RiwayatSekolah, extra=2, fields=('SekolahID','SiswaID_FK','SekolahNama','SekolahThMasuk','SekolahThKeluar','SekolahKet'))
    if request.method == 'POST':
        if form.is_valid():
            siswa_instance = form.save()
            form2 = FormSet2(request.POST or None, instance=siswa_instance) 
            if form2.is_valid():
                form2.save()
            return redirect('index')
    form2 = FormSet2(request.POST or None) 
    formall={}
    formall['form'] = form
    formall['form2'] = form2
    return render(request, 'siswa/tambah_siswa.html', formall)

在模板中：

{{ form2.management_form }}
{{ form2.as_table }}

或

{{ form2.management_form }}    
{% for frm in form2 %}
    {{ frm.as_table }}
{% endfor %}
