python - Delete() View 和模板代码

Question

模板:

<form method="POST" action="/customer/delete/">
<div style="float: right; 
             margin: 0px; padding: 05px; ">
Name:<select  name="customer">
{% for customer in customer %}
<option value="{{ customer.name|escape }}" ></option><br />
{% endfor %}
</select>
<input type=submit value="delete">  
</div>
</form> 

浏览次数:

def delete(request, name):
       Customer.objects.get(name=name).delete()
       return HttpResponse('deleted')

网址.py

(r'^customer/delete/', 'quote.excel.views.delete'),

这不起作用，请更正代码。

Answer 1

您的 URLConf 没有捕获任何数据来传递给变量 name。您需要将其作为 URL 的一部分进行捕获，或者将其保留在 POSTed 参数中进行捕获。

作为 URL 的一部分:

(r'^customer/(?P<name>[a-z]*)/delete/', 'quote.excel.views.delete')

def delete(request, name):
    if request.method == "POST": 
        # GET requests should NEVER delete anything, 
        # or the google bot will wreck your data.
        Customer.objects.get(name=name).delete()

作为后置变量:

(r'^customer/delete/', 'quote.excel.views.delete')

def delete(request):  # No arguments passed in
    if request.method == "POST":
        name = request.POST['name']
        Customer.objects.get(name=name).delete()
