django 使用锚标签传递数据

Question

我正在尝试使用锚标记将数据传递给 django 视图。 我的html文件：

    <div class="card-body dropdown">
      <button class="dropbtn">Pay</button>
      <div class="dropdown-content">
        <a href="{% url 'payments' data='wallet'%}">Payments Wallet</a>
        <a href="{% url 'payments' data='credit_card'%}">Payments Credit card</a>
        <a href="{% url 'payments' data='debitcard'%}">Payments Debitcard</a>
        <a href="{% url 'payments' data='bitcoin'%}">Payments Bitcoin</a>
      </div>
    </div>    
  </div>

我的 urls.py 文件

urlpatterns = [

    path('payments/<str:data>',views.payments,name="payments"),
] + static(settings.MEDIA_URL,document_root =  settings.MEDIA_ROOT)

我的views.py文件

def payments(request):
    query = request.GET.get('data')
    print(query)
    return render(request, '403.html')

错误：未找到任何参数的“付款”反向。尝试了 1 种模式：['customerspayments\/(?P[^/]+)$']

请帮忙。

Answer 1

因为您将参数传递给 url，所以您也必须将该参数添加到函数中。所以，要么只改变你的views.py，只需在函数中添加一个参数

1。最好的方法

# Edit

# Pass parameter like this, if it works or not, for all 4 anchors
<a href="{% url 'payments' wallet %}">Payments Wallet</a>


# Add data to the side of reqeust
def payments(request, data):
    # If you getting query like this, then you don't have to pass parameter to url
    # query = request.GET.get('data')
    query = data

    print(query)
    return render(request, '403.html')

或者，如果您想从 get 方法获取参数，则更改 url。因此，您从 get 方法中获取的以太币如下：

2。另一种方式

# urls.py

urlpatterns = [
    # removed data
    path('payments',views.payments,name="payments"),
] + static(settings.MEDIA_URL,document_root =  settings.MEDIA_ROOT)


# Your template where, your anchor is
<div class="card-body dropdown">
      <button class="dropbtn">Pay</button>
      <div class="dropdown-content">
        <a href="{% url 'payments' %}?data=wallet">Payments Wallet</a>
        <a href="{% url 'payments' %}?data=credit_card">Payments Credit card</a>
        <a href="{% url 'payments' %}?data=debitcard">Payments Debitcard</a>
        <a href="{% url 'payments' %}?data=bitcoin">Payments Bitcoin</a>
      </div>
    </div>    
  </div>


# views.py
# your views.py
def payments(request):
    query = request.GET.get('data')
    print(query)
    return render(request, '403.html')
