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>

查看：

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

Urls.py

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

这不起作用，请更正代码。

Answer 1

你的URLConf没有捕获任何数据传递给变量name。您需要将其作为URL的一部分捕获，或者将其留在POSTed参数中。

作为网址的一部分：

(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()

作为职位变量：

(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()

Answer 2

Customer.objects.get(name = request.POST['name']).delete()

顺便说一下，您确定模板中的action变量确实是'delete'吗？如果不是，则调用的url（因此方法）将不同。

<form method="POST" action="/customer/{{ action }}/">
