Question

我的django模板中有很多按钮。每个按钮都有一个不同的名称{{transaction.id}}。如何在我的视图中参考（提交）单个按钮？

base.html文件

<h3>Open transactions</h3>
    {% for transaction in transactions_open %}
    {{ transaction.id }} {{transaction.timestamp}} {{ transaction.currency }} {{ transaction.sell_or_buy }} {{ transaction.bid }} {{ transaction.date_add }}
    <form action="" method="POST">
    {% csrf_token %}
    <button type="submit" name={{ transaction.id }} value="close">Close</button>
    </form>
    </p>
    {% endfor %}

views.py

class MainView(View):

def get(self, request):

    transactions_open = DealModel.objects.filter(open_or_closed='OPEN')
    transactions_closed = DealModel.objects.filter(open_or_closed='CLOSED')
    content_dict = {'transactions_open': transactions_open,
                    'transactions_closed': transactions_closed}
    return TemplateResponse(request, 'base.html', content_dict)

def post(self,request):

    if request.method == 'POST':
        transactions_open = DealModel.objects.filter(open_or_closed='OPEN')
        transactions_closed = DealModel.objects.filter(open_or_closed='CLOSED')

        if request.POST.get('name???') == 'close':
        content_dict['answer'] = "Closed!!!"
        return TemplateResponse(request, 'base.html', content_dict)

this is my example

Answer 1

第一

def post(self,request): 当请求方法为POST时，系统会调用它，因此您需要检查

第二

此解决方案取决于我从问题中得到的内容
您不需要表单来关闭按钮如果您想隐藏它，可以使用javascript处理它

<ul>{% for transaction in transactions_open %}
<li class="close_button" data-pk="{{ transaction.id }}">{{ transaction.id }} {{transaction.timestamp}} {{ transaction.currency }} {{ transaction.sell_or_buy }} {{ transaction.bid }} {{ transaction.date_add }}

<a type="submit"  value="close">Close</a>

</li>
{% endfor %}</ul>

使用jquery

在javascript文件中

$('.close_button a').onclick(function(){
     $(this).parent(".close_button").hide(); // something like that
$.ajax{
            url: "{% url 'app_label:view_name' %}",
            data: {'data':$(this).data("pk")},
            method: "POST",
            success: function (result,status,xhr) {

                alert('closed Successfully.');

            },

})

处理在视图处关闭交易：

class MyView(View):
    def post(self, request, *args, **kwargs):
        if request.is_ajax():
             id = request.post.get("pk")
             Transaction.objects.get(id=id).close() #develop close method at your model classes

Answer 2

感谢您的回答。以下是我解决问题的方法：

class MainView(View):

    def post(self,request):

    if 'close' in request.POST.values():
        for key, value in request.POST.items():
            if value == 'close':
                deal_id = key # deal_id is the value of {{transaction.id}} in template file.

    if request.POST.get(deal_id) == 'close':
        closing_deal = DealModel.objects.get(id=deal_id)
        closing_deal.open_or_closed = 'Closed'
        closing_deal.save()
        content_dict['answer'] = "Closed!!!"
        return TemplateResponse(request, 'base.html', content_dict)

django多个提交按钮
