Django CreateView-如何调用表单类__init__？ [英] Django CreateView - How do I call form class __init__?

问题描述

我有一个django创建视图，我想调用表单类的 __ init __ ，我不知道该怎么做。

I have a django create view and I want to call the __init__ of the form class and I don't know how to do that.

class PersonCreateView(CreateView):
    model = Person
    form_class = PersonForm

在表单类中，我做了一些逻辑来重新定义一些组合的查询集。我的问题是我不知道如何调用 PersonForm 的 __ init __ 方法或任何其他方法

In the form class I made some logic to redefine the queryset of some combos. My problem is that I don't know how to call the __init__ method, or any other method, of the PersonForm

在此先感谢您的帮助。

推荐答案

您不应不要自己叫它。您可以覆盖 get_form_kwargs 提供额外的参数以传递给表单实例化。

You shouldn't call it yourself. You can override get_form_kwargs to provide extra arguments to pass to the form instantiation.

class PersonCreateView(CreateView):
    model = Person
    form_class = PersonForm

    def get_form_kwargs(self, *args, **kwargs):
        form_kwargs = super(PersonCreateView, self).get_form_kwargs(*args, **kwargs)
        form_kwargs['my_extra_queryset_param'] = get_my_extra_queryset()
        return form_kwargs
