我正在尝试在用 Django 编写的简单搜索和显示应用程序中使用分页。

我已经按照 Djangoproject 的Pagination教程进行操作，但没有数据发送到服务器。

我以前pdb.set_trace()查看代码的输出，GET字典是空的。

这是模板和URLs文件中的代码：

结果.html：

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

网址.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​​：

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})

为什么没有数据发送？我也阅读了其他帖子，但那里的解决方案对我不起作用。他们建议使用 GET 字典中的 'q_word' 值，request.GET.get('q_word')或者request.GET['q_word']通过他们的答案，它应该可以工作，但对我来说不是。

我的错误在哪里？非常感谢您！

问题是提交时查询参数没有附加到 URL 的末尾。我建议您对表单使用以下语法：

<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>

?q_word=search_term这应该使您的 URL在您提交表单时以结尾。

urls.py看起来不错。
