【问题描述】：
我在下面有这段代码。我使用 formset 多次添加相同的表单。但是如果我把这两个表单集放在一起，就像在我看来，每个表单的第一个数据都会被保存。如果我在我的 def 中只放了 1 个表单集，它就可以工作，我放入表单的所有数据都会被保存。有人知道为什么会这样吗？ （对不起我的英语）
Forms.py
class InsereIdioma(forms.ModelForm):
class Meta:
model = Idioma
fields = '__all__'
exclude = ['usuario']
InsereIdiomaFormset = formset_factory(InsereIdioma, extra=1)
class InsereTecnologia(forms.ModelForm):
class Meta:
model = Tecnologia
fields = '__all__'
exclude = ['usuario']
InsereTecnologiaFormset = formset_factory(InsereTecnologia, extra=1)
Views.py
def cadastro_curriculo(request):
if request.method == 'GET':
formset_idioma = InsereIdiomaFormset(request.GET or None)
formset_tecnologia = InsereTecnologiaFormset(request.GET or None)
elif request.method == 'POST':
formset_idioma = InsereIdiomaFormset(request.POST)
formset_tecnologia = InsereTecnologiaFormset(request.POST)
if formset_idioma.is_valid():
for form in formset_idioma:
idioma = form.cleaned_data.get('idioma')
fluencia = form.cleaned_data.get('fluencia')
if idioma and fluencia:
Idioma(
idioma=idioma,
fluencia=fluencia,
usuario=request.user
).save()
if formset_tecnologia.is_valid():
for form in formset_tecnologia:
sistema = form.cleaned_data.get('sistema')
nivel = form.cleaned_data.get('nivel')
if sistema and nivel:
Tecnologia(
sistema=sistema,
nivel=nivel,
usuario=request.user
).save()
return render(request, "personal/curriculo.html", {
'formset_idioma': formset_idioma,
'formset_tecnologia': formset_tecnologia,})

【问题讨论】：
-
查看 POST 参数 onSubmit。也许你只发送一份表格。
-
但是如果我只发送一个表格，这个表格的所有数据都会被保存，第二个表格会被忽略，对吧？这没有发生@Zartch
-
我不确定您的问题是什么。也许如果你向我们展示帖子参数，它会带来一些线索。
-
如果你想使用多个表单集，你应该使用prefix。
