CreateView中的多个表单和表单集

基于类的视图仍然是新的，因此我将其写出来。过程很简单：

首先，为您的对象创建表单。其中一种形式将重复。这里没有什么特别的。

class SonInline(ModelForm):    model = Sonclass FatherForm(ModelForm):    model = Father

然后，创建您的

formset

FatherInlineFormSet = inlineformset_factory(Father,    Son,    form=SonInline,    extra=1,    can_delete=False,    can_order=False)

现在，将其与您的集成

CreateView

class CreateFatherView(CreateView):    template_name = 'father_create.html'    model = Father    form_class = FatherForm # the parent object's form    # On successful form submission    def get_success_url(self):        return reverse('father-created')    # Validate forms    def form_valid(self, form):        ctx = self.get_context_data()        inlines = ctx['inlines']        if inlines.is_valid() and form.is_valid(): self.object = form.save() # saves Father and Children return redirect(self.get_success_url())        else: return self.render_to_response(self.get_context_data(form=form))    def form_invalid(self, form):        return self.render_to_response(self.get_context_data(form=form))    # We populate the context with the forms. Here I'm sending    # the inline forms in `inlines`    def get_context_data(self, **kwargs):        ctx = super(CreateFatherView, self).get_context_data(**kwargs)        if self.request.POST: ctx['form'] = FatherForm(self.request.POST) ctx['inlines'] = FatherInlineFormSet(self.request.POST)        else: ctx['form'] = Father() ctx['inlines'] = FatherInlineFormSet()        return ctx

最后，这是模板：

关键部分是jQuery django-dynamic-formset插件，该插件不断添加新的内联表单：

<form id="father-form" method="POST" enctype="multipart/form-data" action=".">{% csrf_token %}<div >  {% for f in form %}    <div >{{ f.label }}<br />{{ f }}      {% if f.errors %}          {% for v in f.errors %} <br /><span >{{ v }}</span>          {% endfor %}      {% endif %}    </div> {% endfor %}</div><hr /><h2>Sons:</h2><table > <table> {%  for f2 in inlines %}   <tr id="{{ f2.prefix }}-row">      {% for i in f2 %}        <td>{{ i }}{% if i.errors %}<span >{{ i.errors }}</span>{% endif %}        </td>      {% endfor %}   </tr> {% endfor %}</table>{{ inlines.management_form }}<input type="submit"  value="Go Go Gadget &rarr;"></form><script type="text/javascript">    $(function() {        $('#father-form tr').formset({ prefix: '{{ inlines.prefix }}'        });    })</script>
