没有数据使用GET方法发送 [英] No data is sent with GET method

问题描述

我试图在使用Django编写的简单搜索和显示应用程序中使用分页。

我按照 Pagination from Djangoproject，但没有数据被发送到服务器。

我使用 pdb.set_trace（）来查看代码的输出，并且 GET dictionary是空的。

以下是模板中的代码和 URLs 文件：

results.html：

 < form method =GETid =searchFormaction =/ search /> 
< input type =textid =billSearchedname =q_word> 
< input type =submitvalue ={％trans寻找％}> 
< / form> 
  

urls.py：

  urlpatterns = patterns（''，
 url（r'^ $'，'ps.views.bills'，name =bills），
 url（r'^ i18n /'，include（'django.conf.urls.i18n'）），
 url（r'^ search /'，'ps.views.search'，name =search ），）
  

以及适用于此的视图， search.py​​： $ b $ pre $ def search（请求）：
导入pdb
pdb.set_trace（）
searchTerm = request.GET.get（'q_word'）
if searchTerm == None：
searchTerm =test
found_bills = Bill.objects.filter（name__icontains = searchTerm）
page = request.GET.get（'page'）
paginator = Paginator（found_bills，25）
try：
current_page = paginator.page（page）
PageNotAnInteger ：
current_page = paginator.page（1）
除了（EmptyPage，InvalidPage）：
current_page = paginator.page（paginator .nu​​m_pages）
return render（request，'results.html'，{results：current_page，term：searchTerm}）


为什么没有数据被发送？我也阅读过其他文章，但那里的解决方案并不适合我。他们建议通过 request.GET.get（'q_word'）或者使用 request.GET来访问GET字典中的'q_word' 'q_word'] 和他们的答案，它应该工作，但对我来说它不是。

我的错误在哪里？

解决方案

问题是，查询参数不会被追加到URL的末尾提交。我建议你在表单中使用这种语法：

 < form id =searchFormmethod =GETaction = /搜索/> 
< fieldset> 
< input type =textid =billSearchedname =q_word> 
< br /> 
< input type =submitvalue ={％trans寻找％}> 
< / fieldset> 
< / form> 
  

这应该使您的网址以结尾？q_word = search_term



urls.py 看起来不错。

I'm trying to use Pagination in my simple search and display application written in Django.

I've followed the tutorial on Pagination from Djangoproject but there is no data being sent to the server.

I've used pdb.set_trace() to view the output of the code, and the GET dictionary is empty.

Here is the code in the template and the URLs file:

results.html:

<form method="GET" id="searchForm" action="/search/">
        <input type="text" id="billSearched" name="q_word">
        <input type="submit" value="{% trans "Look for" %}">
</form>

urls.py:

urlpatterns = patterns('',
    url(r'^$','ps.views.bills',name="bills"),
    url(r'^i18n/', include('django.conf.urls.i18n')),
    url(r'^search/','ps.views.search',name="search"),)

and the view that works with this, search.py:

def search(request):
    import pdb
    pdb.set_trace()
    searchTerm = request.GET.get('q_word')
    if searchTerm == None:
        searchTerm = "test"
    found_bills = Bill.objects.filter(name__icontains = searchTerm)
    page = request.GET.get('page')
    paginator = Paginator(found_bills,25)
    try:
        current_page = paginator.page(page)
    except PageNotAnInteger:
        current_page = paginator.page(1)
    except (EmptyPage, InvalidPage):
        current_page = paginator.page(paginator.num_pages)
return render(request,'results.html',{"results":current_page,"term": searchTerm})

Why is there no data being sent? I have read other posts as well and the solutions there didn't work for me. They suggested to access the 'q_word' value in the GET dictionary with either request.GET.get('q_word') or with request.GET['q_word'] and by their answers it should work, but for me it doesn't.

Where is my mistake? Thank you very much in advance!

解决方案

The problem is that query parameters are not being appended to the end of the URL when you submit. I suggest you use this syntax for the form:

<form id="searchForm" method="GET" action="/search/">
<fieldset>
<input type="text" id="billSearched" name="q_word">
<br />
<input type="submit" value="{% trans "Look for" %}">
</fieldset>
</form>

This should make your URL end with ?q_word=search_term when you submit the form.

urls.py looks fine.
