django没有返回适当的响应 [英] django not returning appropriate response

问题描述

我有一个包含复选框和一个按钮的模板。我想要，当我选择所有复选框并按下按钮时，它应该返回值并显示为httpresponse。

Index.html：

 < form method =POSTaction =/ test /> 
 {％csrf_token％} 
< div id =row-1> 
< button name =packid =pack> Pack< / button> 
< / div> 
< div id =row-2> 
< table> 
< thead> 
< tr> 
< th< input type =checkboxonClick =toggle（this，'no'）>< / th> 
< th>订单ID< / th> 
< / tr> 
< / thead> 
< tbody> 
< tr> 
< td>< input type =checkboxname =novalue =10000001> 10000001< / td> 
< / tr> 
< tr> 
< td>< input type =checkboxname =novalue =10000002> 10000002< / td> 
< / tr> 
< / tbody> 
< / table> 
< / div> 
< / form> 
  

views.py：

  from django.shortcuts import render，render_to_response 
 from django.http import HttpResponse 
 from test1 import forms 
 
 def index（request）：
 return render（request，'index.html'）
 
 def pack（request）：
 oid_list = [] 
 form = forms.PackOrders（request.POST或None） 
如果request.method =='POST'：
 for form.cleaned_data ['no']：
 oid_list.append（item）
 return HttpResponse（'，' .join（oid_list））
  

urls.py：

$ b $从django.conf.urls导入模式
从django.conf.urls导入url
从test1导入视图

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

forms.py：

 从django import for ms 
 
 class PackOrders（forms.Form）：
 order_items = forms.CharField（）
  

问题是，当我清理复选框，我返回代码，它只是重新加载index.html而不是显示复选框的值。

预期输出：

  10000001,10000002 
  

代码有什么问题？

编辑：

项目urls.py：

  from django.conf.urls import include，url 
 from django.contrib import admin 
 
 urlpatterns = [
 url（r'^ admin /'，include（admin.site.urls）），
 url（r'^ $'，include（'test1.urls '）），
 url（r'^ test /'，include（'test1.urls'）），
] 
  

解决方案

您的应用程序urlconf已经包含在您的root urlconf中。你应该只做一次但是，您应该从包含它的URL中删除$：

  url（r'^'，include（'test1。 urls'）），
  

如果您使用第二个版本，使用'test /'前缀，您将创建'/ test /'和'/ test / test /'的URL，这可能不是你想要的。

注意，如我所说评论时，您应该始终通过其名称引用URL，而不是直接引用URL。所以你的表单动作应该是{％url'pack'％}。

I have a template with checkbox and a button. I want , when i select all checkbox and press the button it should return the values and display it as a httpresponse.

Index.html:

<form method="POST" action="/test/">
    {% csrf_token %}
    <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>

views.py:

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

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

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

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'^test/', views.pack, name='pack'),)

forms.py:

from django import forms

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

The problem is that when i cleck the checkbox and i return the code it just reload the index.html instead of displaying the values of checkbox.

Expected Output:

10000001,10000002

What is wrong with the code?

EDIT :

projects urls.py:

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', include('test1.urls')),
    url(r'^test/', include('test1.urls')),
]

解决方案

You've included your app urlconf into your root urlconf twice. You should only do it once. However, you should remove the $ from the URL that includes it:

url(r'^', include('test1.urls')),

If you used the second version instead, with the 'test/' prefix, you would create URLs at '/test/' and '/test/test/', which presumably isn't what you want.

Note though that as I said in the comment, you should always reference URLs via their name, not directly. So your form action should be "{% url 'pack' %}".
