带有表单的基于 Django 类的视图 ListView [英] Django class based view ListView with form

问题描述

主视图是一个简单的分页 ListView，我想向其中添加一个搜索表单.

The main view is a simple paginated ListView and I want to add a search form to it.

我认为这样的事情可以解决问题:

I thought something like this would do the trick:

class MyListView(ListView, FormView):
    form_class = MySearchForm
    success_url = 'my-sucess-url'
    model = MyModel
    # ...

但显然我弄错了..而且我在官方文档中找不到如何做.

But apparently I got it wrong .. and I can't find how to do it in the official documentation.

建议?

对于我的实现，我需要一个在 get 和 post 上都返回 ListView 的表单视图.我不喜欢重复 get 函数的内容，但它需要进行一些更改.现在也可以从 get_queryset 使用 self.form 获取该表单.

For my implementation I needed a form view that returned a ListView on both get and post. I don't like having to repeat the contents of the get function but it needed a couple of changes. The form is now available from get_queryset now too with self.form.

from django.http import Http404
from django.utils.translation import ugettext as _
from django.views.generic.edit import FormMixin
from django.views.generic.list import ListView

class FormListView(FormMixin, ListView):
    def get(self, request, *args, **kwargs):
        # From ProcessFormMixin
        form_class = self.get_form_class()
        self.form = self.get_form(form_class)

        # From BaseListView
        self.object_list = self.get_queryset()
        allow_empty = self.get_allow_empty()
        if not allow_empty and len(self.object_list) == 0:
            raise Http404(_(u"Empty list and '%(class_name)s.allow_empty' is False.")
                          % {'class_name': self.__class__.__name__})

        context = self.get_context_data(object_list=self.object_list, form=self.form)
        return self.render_to_response(context)

    def post(self, request, *args, **kwargs):
        return self.get(request, *args, **kwargs)


class MyListView(FormListView):
    form_class = MySearchForm
    model = MyModel
    # ...
