问题描述
我想创建一个与另一个模型一一对应的模型。即Model1与Model2具有一对一的关系。我希望我的表单显示来自Model1以及Model2的所有字段。
还有一种在视图中显示的最佳方法。

推荐答案
您不需要创建单一形式为两个型号。使用两个django表单并将它们放在单个< form>
标签内:
You don't need to create the single form for two models. Use two django forms and place them inside the single <form>
tag:
class Model1Form(forms.ModelForm):
class Meta:
model = Model1
class Model2Form(forms.ModelForm):
class Meta:
model = Model2
exclude = ('model1_one_to_one_field', )
def create_models(request):
if request.method == 'POST':
form1 = Model1Form(request.POST)
form2 = Model2Form(request.POST)
if all([form1.is_valid(), form2.is_valid()]):
model1 = form1.save()
model2 = form2.save(commit=False)
model2.model1_one_to_one_field = model1
model2.save()
return redirect('create_models_success')
else:
form1 = Model1Form()
form2 = Model2Form()
return render(request, 'create_models.html',
{'form1': form1, 'form2': form2})
然后$ code> create_models。 html 模板:
And then the create_models.html
template:
<form action="." method="POST">
{% csrf_token %}
{{ form1.as_p }}
{{ form2.as_p }}
<button type="submit">Submit</button>
</form>
