Question

...我试图用2种不同模型保存2个表格保存的数据，但我不知道如何保存关系。保存数据后，我需要将它们显示为一个html表单，当用户键入信息时也是一个html表单。

有了这个观点，我在两个模型中保存了信息，但是我无法保存关系。可能是POST有一个不同的工作在这个问题....我不知道

view.py

def proposeActivity(request):
if request.method == "POST":
    form_1 = ActivityProposedForm(request.POST, prefix="form_1")
    form_2 = ActivityUrl_activity(request.POST, prefix="form_2")
    if form_1.is_valid() and form_2.is_valid():
        post_1 = form_1.save(commit=False)
        post_2 = form_2.save(commit=False)
        post_1.author = request.user
        post_2.author = request.user
        post_1.save()
        post_2.save()
        return redirect('proposedActivities')
else:
    form_1 = ActivityProposedForm(prefix="form_1")
    form_2 = ActivityUrl_activity(prefix="form_2")

return render(request, 'registerActivity.html', {'form_1': form_1, 'form_2': form_2})

forms.py

class ActivityProposedForm(forms.ModelForm):

        metodologias_choices = [(metodologia.id, metodologia.methodology_name) for metodologia in Methodology.objects.all()]

然后解决方案是......

views.py

            post_2 = form_2.save(commit=False)  
            post_1 = form_1.save(commit=False)

            post_2.author = request.user
            post_1.author = request.user

            post_2.save()
            post_1.foreign_url = post_2
            post_1.save()
