将初始化传递给Django的ModelFormSet [英] Passing initial into Django's ModelFormSet

问题描述

我有一个模型表单，我需要将关键字初始化传递给（在表单集中有一些初始值，例如日期设置为今天）。据我所知，查询参数（默认为YourModel.objects.all（））将覆盖此初始空表单的创建能力。我将查询器指定为：YourModel.objects.none（），它阻止它使用数据库中的条目填写表单集，但是我仍然无法弄清楚如何有效地传递初始化。我需要从ModelForm中子类化一个方法吗？

解决方案

Django 1.4中的新增功能...如果在modelformset上设置初始化现在只适用于额外表单，而不适用于那些绑定到查询器实例的表单：

https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#providing-initial-values

所以上面的各种hack不再是必需的，使用initial是答案。

I have a model formset that I need to pass the keyword initial in to (to have some initial values in the formset, such as date set to today). As far as I can tell, the queryset argument (which defaults to YourModel.objects.all()) overrides this ability for initial empty forms to be created. I specified the queryset as: YourModel.objects.none(), which prevents it from filling in the formset with entries from the database, but I still can't figure out how to pass initial in effectively. Do I need to subclass a method from ModelForm?

解决方案

New in Django 1.4 ...if you set initial on a modelformset it now only applies to the 'extra' forms, not those bound to instances from the queryset:

https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#providing-initial-values

So the various hacks above are no longer necessary and using initial is the answer.
