一个模板 Django 中的 ListView 和 CreateView [英] ListView and CreateView in one template Django

问题描述

我正在设计一个页面，人们可以在其中查看和创建某种类型的对象(这些对象是模型 Project 的实例).

据我所知，如果没有非常混乱的代码，我无法在一个视图中完成，所以我试图了解如何使用一个模板来显示两个视图(ProjectCreateView 和 ProjectListView).

现在，这就是我的工作:

views.py:

class ProjectCreateView(CreateView):模型 = 项目template_name = "文件上传/project_list.html"字段 = [名称"]def get_context_data(self, **kwargs):context = super(ProjectCreateView, self).get_context_data(**kwargs)返回上下文类 ProjectListView(ListView):模型 = 项目def get_context_data(self, **kwargs):context = super(ProjectListView, self).get_context_data(**kwargs)返回上下文类项目视图(视图):模型 = 项目def get(self, request, *args, **kwargs):视图 = ProjectListView.as_view()返回视图(请求，*args，**kwargs)def post(self, request, *args, **kwargs):视图 = ProjectCreateView.as_view()返回视图(请求，*args，**kwargs)

urls.py

urlpatterns = patterns('',url(r'^projects/$', ProjectView.as_view(), name="projects"),)

models.py

class Project(models.Model):name = models.CharField(max_length=200)def get_absolute_url(self):返回反向(项目")

表单代码

<div class="row fileupload-buttonbar"><div class="span7"><span class="btn btn-primary fileinput-button"><i class="icon-plus icon-white"></i><span>新项目</span><输入类型=提交"名称=创建"></span><button type="button" class="btn btn-danger delete"><i class="icon-trash icon-white"></i><span>删除项目</span><input type="checkbox" class="toggle">

{{ form.as_p }}

<table class="table table-striped"><tbody class="files"></tbody></table></表单>

但是，使用此配置，表单仅在按下按钮后显示名称"字段，输入名称后，我得到:

NoReverseMatch at/upload/projects/未找到带有参数()"和关键字参数{}"的项目"的反转.

正因如此，我猜测有一种比我正在做的更容易实现的方法.我很感激任何帮助.

解决方案

一个整洁的基于函数的视图来列出和创建对象...

from django.shortcuts 导入渲染# 模型和表单导入def list_and_create(request):form = YourModelForm(request.POST or None)如果 request.method == 'POST' 和 form.is_valid():表单.save()# 注意这是在保存表单以获取新对象之后出现的对象 = YourModel.objects.all()return render(request, 'your-template.html', {'objects': objects, 'form': form})

I'm designing a page in which people can view and create objects of a certain sort (the objects are instances of the model Project).

As I understand it, I can't do it in one view without horribly messy code, so I am trying to understand how I can use one template to show two views (the ProjectCreateView and the ProjectListView).

Right now, this is what I am working with:

views.py:

class ProjectCreateView(CreateView):
    model = Project
    template_name = "fileupload/project_list.html"
    fields = ["name"]

    def get_context_data(self, **kwargs):
        context = super(ProjectCreateView, self).get_context_data(**kwargs)
        return context

class ProjectListView(ListView):
    model = Project

    def get_context_data(self, **kwargs):
        context = super(ProjectListView, self).get_context_data(**kwargs)
        return context

class ProjectView(View):
    model = Project
    def get(self, request, *args, **kwargs):
        view = ProjectListView.as_view()
        return view(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
        view = ProjectCreateView.as_view()
        return view(request, *args, **kwargs)

urls.py

urlpatterns = patterns('',
    url(r'^projects/$', ProjectView.as_view(), name="projects"),
)

models.py

class Project(models.Model):
    name = models.CharField(max_length=200)

    def get_absolute_url(self):
        return reverse("projects")

Code for the form

<form id="fileupload" method="post" action="." enctype="multipart/form-data">
    <div class="row fileupload-buttonbar">
        <div class="span7">
            <span class="btn btn-primary fileinput-button">
                <i class="icon-plus icon-white"></i>
                <span>New Project</span>
                <input type="submit" name="Create">
            </span>
            <button type="button" class="btn btn-danger delete">
                <i class="icon-trash icon-white"></i>
                <span>Delete Project</span>
            </button>
            <input type="checkbox" class="toggle">
        </div>
        {{ form.as_p }}
    </div>
    <table class="table table-striped"><tbody class="files"></tbody></table>
</form>

However, with this configuration the form only shows the "name" field after the button has been pressed, and after entering in a name I get this:

NoReverseMatch at /upload/projects/
Reverse for 'projects' with arguments '()' and keyword arguments '{}' not found.

Because of that, I'm guessing that there's a much easier way of implementing this than what I am doing. I'd appreciate any help.

解决方案

One un-messy function-based view to list and create objects...

from django.shortcuts import render
# model and form imports

def list_and_create(request):
    form = YourModelForm(request.POST or None)
    if request.method == 'POST' and form.is_valid():
        form.save()

    # notice this comes after saving the form to pick up new objects
    objects = YourModel.objects.all()
    return render(request, 'your-template.html', {'objects': objects, 'form': form})
