模板渲染期间的 Django 错误

Question

I am trying to pass values of multiple checkbox from a html template to views.py and then show those values in response. I created a forms.py in my application and defined a class. i then passed the value to pack method of views.py.

template:

<form method="POST" action="{% url 'pack' %}">
    <div id="row-1">
        <button name="pack" id="pack">Pack</button>
    </div>
    <div id="row-2">
        <table>
            <thead>
                <tr>
                    <th><input type="checkbox" onClick="toggle(this, 'no')"></th>
                    <th>Order Id</th>
                </tr>
            </thead>
            <tbody>
                <tr>
                    <td><input type="checkbox" name="no" value="10000001">10000001</td>
                </tr>
                <tr>
                    <td><input type="checkbox" name="no" value="10000002">10000002</td>
                </tr>
            </tbody>
        </table>
    </div>
</form>
<script type="text/javascript">
    function toggle(source, text) {
        checkboxes = document.getElementsByName(text);
        for(var i=0, n=checkboxes.length;i<n;i++) {
            checkboxes[i].checked = source.checked;
            }
        }
</script>

My views.py:

from django.shortcuts import render
from django.http import HttpResponse
from test1 import forms

def index(request):
    return render(request, 'index.html')

def pack(request):
    oid_list = []
    form = PackOrders(request.POST or None)
    if request.method == 'POST':
        for item in form.cleaned_data['no']:
            oid_list.append(item)
    return HttpResponse(oid_list)

forms.py:

from django import forms

class PackOrders(forms.Form):
    order_items = forms.CharField()

urls.py:

from django.conf.urls import patterns
from django.conf.urls import url
from test1 import views

urlpatterns = patterns('', 
                    url(r'^$', views.index, name='index'),
                    url(r'^index.html', views.index, name='index1'),
                    url(r'^test/', 'views.pack', name='pack'),)

what is wrong with the code?

EDIT: It is throwing Error during template rendering

Traceback points to <form method="POST" action="{% url 'pack' %}">

Please point out errors as this is my first django project.

Answer 1

In the form's html code, simply set the action attribute to action='/test/'.

Again in views.py

if request.method == 'POST':
    list_of_ids = request.POST.getlist('no')
    for id in list_of_ids:
        oid_list.append(id)

try this, it should help
