如何预填充Django（非模型）表单（如何将值列表从view.py传递到表单中的ChoiceField）？

我读过类似的文章，但什么也没找到。 我其余的代码工作得很好。 问题在于： 我在我的views.py中生成一个由2x元组组成的列表

list\u来预填充表单1

，并需要将该列表传递给forms.py中的表单

views.py
from django.http import HttpResponse, HttpRequest, HttpResponseRedirect
from .models import *

def n01_size_kss(request):
    if request.method == 'POST':
        form = KSS_Form(request.POST)
        context = {'form':form}

        if form.is_valid():
            filtertype, context = n01_context_cleaned_data(form.cleaned_data)

            if filtertype != "none":
                list_to_prepopulate_the_form1 = prepare_dictionary_form2(context)
                form1 = KSS_Form1(initial={'list1'=list_to_prepopulate_the_form1})
                context = {'form':form1, **context}
            return render(request, 'af/size/01_kss_size2.html', context)
    else:
        context = {'form':KSS_Form()}
        return render(request, 'af/size/01_kss_size1.html', context)

正确的方法是什么？

谢谢

将列表作为选项分配给表单字段

druckstufe

，如下所示：

views.py
from django.http import HttpResponse, HttpRequest, HttpResponseRedirect
from .models import *

def n01_size_kss(request):
    if request.method == 'POST':
        form = KSS_Form(request.POST)
        context = {'form':form}

        if form.is_valid():
            filtertype, context = n01_context_cleaned_data(form.cleaned_data)

            if filtertype != "none":
                list_to_prepopulate_the_form1 = prepare_dictionary_form2(context)
                form1 = KSS_Form1()
                
                # magic here
                form1.fields['druckstufe'].choices = list_to_prepopulate_the_form1

                context = {'form':form1, **context}
            return render(request, 'af/size/01_kss_size2.html', context)
    else:
        context = {'form':KSS_Form()}
        return render(request, 'af/size/01_kss_size1.html', context)

@太酷了！然后考虑接受这个答案。快乐编码！

views.py
from django.http import HttpResponse, HttpRequest, HttpResponseRedirect
from .models import *

def n01_size_kss(request):
    if request.method == 'POST':
        form = KSS_Form(request.POST)
        context = {'form':form}

        if form.is_valid():
            filtertype, context = n01_context_cleaned_data(form.cleaned_data)

            if filtertype != "none":
                list_to_prepopulate_the_form1 = prepare_dictionary_form2(context)
                form1 = KSS_Form1()
                
                # magic here
                form1.fields['druckstufe'].choices = list_to_prepopulate_the_form1

                context = {'form':form1, **context}
            return render(request, 'af/size/01_kss_size2.html', context)
    else:
        context = {'form':KSS_Form()}
        return render(request, 'af/size/01_kss_size1.html', context)
