Question

我正在尝试在同一视图中使用多个表单集，并使用列表对其进行缩放。但是，它不起作用。我基于documentation为该代码建模。但是，它会给管理表单篡改带来确认错误。

from django.shortcuts import render
from .forms import modelformset_factory, AssumptionsForm
from .models import Assumptions

model_names = ['A', 'B', 'C', 'D', 'E', 'F', 'G']

def get_assumptions(request):

    AssumptionsFormset = modelformset_factory(
    Assumptions, form=AssumptionsForm, extra=5)

    if request.method == 'POST':

        formsets = [AssumptionsFormset(request.POST, prefix=thing) for thing in model_names]

        if all([formset.is_valid() for formset in formsets]):

            for formset in formsets:

                for form in formset:

                    form.save()

    else:

        formsets = [AssumptionsFormset(request.POST, prefix=thing) for thing in model_names]

    return render(request, 'assumptions.html', {'formsets': formsets})

class Assumptions(models.Model):

    Worst = models.FloatField(null=True, blank=True, default=None)
    Base = models.FloatField(null=True, blank=True, default=None)
    Best = models.FloatField(null=True, blank=True, default=None)
