如何在Django中使用URL接收/发送数据？

Question

我是刚到django的。我需要写一个应用程序，读，写数据使用服务链接。你知道吗

例如，我有如下URL：

http://site.com/something/LoadProducts/

http://site.com/something/DeleteProductById/等等。你知道吗

有没有人能给我举个例子，让我用GET，POST来处理CRUD操作的url。谢谢

from django.shortcuts import render, get_object_or_404
# form imports here
# model imports here

# get all objects
def get_view(request):
    objects = YourModel.objects.all()
    return render(request, 'all-objects.html', {'objects': objects}

# make a new object
def make_new_obj(request):
    form = YourForm(request.POST or None)
    if request.method == 'POST':
        if form.is_valid():
            form.save()
    return render(request, 'make-new-obj.html', {'form': form}

# get an object by id
def get_single_object_view(request, id):
    obj = get_object_or_404(YourModel, pk=id)
    return render(request, 'obj-detail.html', {'obj': obj}

# update an object
def update_obj(request, id):
    obj = get_object_or_404(YourModel, pk=id)
    form = YourForm(request.POST or None, instance=obj)
    if request.method == 'POST':
        if form.is_valid():
            form.save()
    return render(request, 'update-obj.html',
        {'obj': obj, 'form': form}

# delete an object
def delete_obj(request, id):
    obj = get_object_or_404(YourModel, pk=id)
    obj.delete()
    # do something else like redirect to the object index, etc
    # you'll probably want to make this a two-step process

显然，这里有很多代码可以组合，所以可以根据需要进行混合和匹配。所有这些代码在Django文档中都有很好的介绍。。。你知道吗
