Question

我正在寻找在Django应用程序中复制以下表单结构的方法。这些已经在PHP应用程序中进行了编码。

在第一页上有两种单独的输入表单，其中顶部表单与底部表单略有不同。目前，它们是form.py下的两个单独的表单，但可以组合在一起：

forms.py：

# forms.py
from django import forms
from .models import Data2, Data3 

class ExampleEntryFormTop(forms.Form):
    example_date = forms.DateField(widget=forms.HiddenInput())
    data_top = forms.IntegerField()
    data2 = forms.ModelChoiceField(Data2.objects, to_field_name="name", empty_label=None, widget=forms.RadioSelect)
    additional = forms.MultipleChoiceField(choices=(
        ('one', 'One'),
        ('two', 'Two'),
        ('three', 'Three')),
        widget=forms.CheckboxSelectMultiple
    )
    data3 = forms.ModelChoiceField(Data3.objects, empty_label=None, widget=forms.RadioSelect)
    data4 = forms.MultipleChoiceField(choices=(
        ('alpha', 'Alpha'),
        ('beta', 'Beta'),
        ('gamma', 'Gamma')),
        widget=forms.CheckboxSelectMultiple
        )


class ExampleEntryFormBottom(forms.Form):
    example_date = forms.DateField(widget=forms.HiddenInput())
    data_bottom = forms.IntegerField()
    data2 = forms.ModelChoiceField(Data2.objects, to_field_name="name", empty_label=None, widget=forms.RadioSelect)
    additional = forms.MultipleChoiceField(choices=(
        ('one', 'One'),
        ('two', 'Two'),
        ('three', 'Three')),
        widget=forms.CheckboxSelectMultiple
    )
    data3 = forms.ModelChoiceField(Data2.objects, empty_label=None, widget=forms.RadioSelect)


class ExampleEntryFormPage2(forms.Form):
    example_date = forms.DateField(widget=forms.HiddenInput())
    data_top = forms.IntegerField()
    data_bottom = forms.IntegerField()
    data2 = forms.ModelChoiceField(Data2.objects, to_field_name="name", empty_label=None, widget=forms.RadioSelect)
    additional = forms.MultipleChoiceField(choices=(
        ('one', 'One'),
        ('two', 'Two'),
        ('three', 'Three')),
        widget=forms.CheckboxSelectMultiple
    )
    data3 = forms.ModelChoiceField(Data2.objects, empty_label=None, widget=forms.RadioSelect)

在向导的第二页上，我需要预加载接下来的三天。我一直在使用以下内容来创建表单集：

forms.py：

def get_example_set():
    initial_date = date.today()
    example_days = [initial_date + timedelta(days=x) for x in range(2, 5)]
    ExampleFormset = formset_factory(ExampleEntryFormPage2, max_num=len(example_days))
    form_set = ExampleFormset(initial=[{'example_date': x} for x in example_days])
    return form_set

但是，我能够将此表单集传递到SessionWizardView的唯一方法是使用get_context_data，它可以传入表单集，但感觉不正确：

views.py：

from formtools.wizard.views import SessionWizardView
from .forms import get_example_set
from django.shortcuts import render
from datetime import date, timedelta


class ExampleWizardView(SessionWizardView):
    template_name = 'example_entry_wizard.html'

    def done(self, form_list, **kwargs):
        return render(self.request, 'done.html', {
            'form_data': [form.cleaned_data for form in form_list],
            })

    def get_form(self, step=None, data=None, files=None):
        form = super(ExampleWizardView, self).get_form(step, data, files)
        step = step or self.steps.current
        form = get_example_set()
        return form

    def get_context_data(self, **kwargs):
        # FIXME: Make this time-zone aware
        context = super(ExampleWizardView, self).get_context_data(**kwargs)
        initial_date = date.today()
        weekday = initial_date.strftime("%A")
        day_one_example = initial_date + timedelta(days=1)
        context['initial_date'] = initial_date
        context['weekday'] = weekday
        context['day_one_example'] = day_one_example
        context['formset'] = get_example_set()
        context['formset_type'] = type(get_example_set())
        return context

    def form_valid(self, form):
        form.save_example()
        return super().form_valid(form)

我觉得我正在努力使用此工具，但我不确定如何最好地使用它。到目前为止，我所看到的示例建议修改get_form使其正常工作，但是我不确定如何针对这些类型的表单进行操作。

似乎每当我尝试使用get_example_set函数设置表单集时都会遇到问题，因为我没有FormSet类，而是有一个对象。

我也知道这里还没有第一页的代码。我仍在尝试找出将其添加到FormWizard中的最佳方法。

如何将Django表单，表单集和formwizard合并为多步骤表单
