Python 内联表单集无效错误：列表索引超出范围

尊敬的Django专家

通过将内联表单集与基于类的视图合并，通过列表索引超出范围的异常，该表单集是有效的

我的代码很简单（我猜）

回溯： get_响应中的文件“/usr/local/lib/python2.7/dist packages/django/core/handlers/base.py” 114响应=包装的回调（请求，*回调参数，**回调参数） 视图中的文件“/usr/local/lib/python2.7/dist-packages/django/views/generic/base.py” 69返回自调度（请求，*args，**kwargs） 文件“/usr/local/lib/python2.7/dist-packages/brages/views.py”在分派中 140请求，*args，**kwargs） 分派中的文件“/usr/local/lib/python2.7/dist packages/django/views/generic/base.py” 87返回处理程序（请求、*args、**kwargs） post中的文件“/home/ramez/code/eventsrun project/eventsrun/eventsrunpa/views.py” 483如果form.is\u valid（）和URL\u form.is\u valid（）： 中的文件“/usr/local/lib/python2.7/dist packages/django/forms/formsets.py”有效 292err=自我错误 文件“/usr/local/lib/python2.7/dist packages/django/forms/formsets.py”出现错误 267self.full_clean（） 文件“/usr/local/lib/python2.7/dist packages/django/forms/formsets.py”的完整格式 314形式=自我。形式[i] 文件“/usr/local/lib/python2.7/dist packages/django/utils/functional.py”__ 49res=instance.\uuuuu dict\uuuuu[self.func.\uuuuuu name\uuuuuuu]=self.func（实例） forms中的文件“/usr/local/lib/python2.7/dist packages/django/forms/formsets.py” 133forms=[self.\u construct\u form（i）表示x范围内的i（self.total\u form\u count（））] 文件“/usr/local/lib/python2.7/dist packages/django/forms/models.py”，格式为 848形式=超级（BaseInlineFormSet，self）。\u构造\u形式（i，**kwargs） 文件“/usr/local/lib/python2.7/dist packages/django/forms/models.py”，格式为 572kwargs['instance']=self.get_queryset（）[i] 文件“/usr/local/lib/python2.7/dist-packages/django/db/models/query.py”位于__ 115返回self.\u结果\u缓存[k] 异常类型：索引器位于/places/Place formset/edit/ 异常值：列表索引超出范围 知道这是什么吗

提前谢谢

我还试图跳过验证（is_valid（）），但仍然在.save（）中出现了相同的错误。

结果是我向inlineformset发送了一个空实例。。。不是很聪明，但出于某种原因，我认为表单（request.POST）实际上会知道这是一个现有记录

工作执行：

class EntityUpdate(updateView):
    def post(self, request, *args, **kwargs):
        form_class = self.get_form_class() 
        form = self.get_form(form_class)
        p = get_object_or_404(Entity, slug=kwargs['slug'])
        urls_form = myforms.url_formset(self.request.POST , instance = p) #Loading the formset with the appropriate instance parameter
        if form.is_valid() and urls_form.is_valid():
            return self.form_valid(form , urls_form)
        else:
            return self.form_invalid(form, urls_form)

内联表单集在CBV中不受直接支持。也许这会有帮助：两个问题：你在用self.object=None行做什么，看起来就像你在分配“form”两次，在第二次之前对你创建的两行表单什么都不做！很抱歉迟了答复。1） self.object=None是一种黑客行为，因为在CBV执行之后，它会检查self.object 2）您完全正确。这个片段很老了，我以前“更”是个新手现在。。。因此，这段代码包含了很多黑客，我应该修改，因为我现在比较了解了。对答案进行了编辑。非常感谢。 Traceback: File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py" in get_response 114. response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/usr/local/lib/python2.7/dist-packages/django/views/generic/base.py" in view 69. return self.dispatch(request, *args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/braces/views.py" in dispatch 140. request, *args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/django/views/generic/base.py" in dispatch 87. return handler(request, *args, **kwargs) File "/home/ramez/code/eventsrun-project/eventsrun/eventsrunapp/views.py" in post 483. if form.is_valid() and urls_form.is_valid(): File "/usr/local/lib/python2.7/dist-packages/django/forms/formsets.py" in is_valid 292. err = self.errors File "/usr/local/lib/python2.7/dist-packages/django/forms/formsets.py" in errors 267. self.full_clean() File "/usr/local/lib/python2.7/dist-packages/django/forms/formsets.py" in full_clean 314. form = self.forms[i] File "/usr/local/lib/python2.7/dist-packages/django/utils/functional.py" in __get__ 49. res = instance.__dict__[self.func.__name__] = self.func(instance) File "/usr/local/lib/python2.7/dist-packages/django/forms/formsets.py" in forms 133. forms = [self._construct_form(i) for i in xrange(self.total_form_count())] File "/usr/local/lib/python2.7/dist-packages/django/forms/models.py" in _construct_form 848. form = super(BaseInlineFormSet, self)._construct_form(i, **kwargs) File "/usr/local/lib/python2.7/dist-packages/django/forms/models.py" in _construct_form 572. kwargs['instance'] = self.get_queryset()[i] File "/usr/local/lib/python2.7/dist-packages/django/db/models/query.py" in __getitem__ 115. return self._result_cache[k] Exception Type: IndexError at /places/Place-formset/edit/ Exception Value: list index out of range
