在Django中编写一个非常基本的搜索表单 [英] Writing a very basic search form in Django

问题描述

所以我试图让事情变得非常简单。我想在我的搜索框中输入一个字词，并将其显示在生成的页面上。

我的表单的HTML是

 < form method = getaction =/ results /class =navbar-form pull-right> 
< input type =textid =searchBoxclass =input-medium search-queryname =qplaceholder =Search> 
< input type =submitclass =btnvalue =Search> 
< / form> 
  

views.py如下所示：

< pre $ def search（request）：
query = request.GET ['q']
t = loader.get_template（'template / results.html'）
c = Context（{'query'：query，}）
return HttpResponse（t.render（c））


最后，结果模板包含：

 < div>您搜索的是：{{query} }< / div> 
  

这里是urls.py

  urlpatterns = patterns（''，
 url（r'^ home / $'，'search.views.home'），
 url（r'^ results / $ '，'search.views.results'），
  

{{query}} space。

解决方案

views.py 应该是 search ，但正如我在 urls.py 您不要在任何地方调用 search 方法。

您在哪里执行 search 方法？

网址应该是这样的：

  urlpatterns = patterns（''，
 url（r'^ home / $'，'search.views.home'），
 url（r'^ results / $'，'search.views.search'），
＃或者至少有一个搜索视图的网址
  

注意表单中的动作属性

它是 action =/ results /，这意味着结果视图是应该处理表单的人。您也可以将它更改为 action =/ search /，并让您的urls如下所示：

  urlpatterns = patterns（''，
 url（r'^ home / $'，'search.views.home'），
 url（r'^ results / $' ，'search.views.results'），
 url（r'^ search / $'，'search.views.search'），
  

So I'm trying to get something very simple accomplished. I want to enter a term into my search box, and display it on the resulting page.

My HTML for the form is

<form method="get" action="/results/" class="navbar-form pull-right">
<input type="text" id="searchBox" class="input-medium search-query" name="q" placeholder="Search">
<input type="submit" class="btn" value="Search" >
</form>

The views.py looks like this:

def search(request):
    query = request.GET['q']
    t = loader.get_template('template/results.html')
    c = Context({ 'query': query,})
    return HttpResponse(t.render(c))

And finally the result template contains:

<div>You searched for: {{ query }} </div>

Here's the urls.py

urlpatterns = patterns('',
url(r'^home/$', 'search.views.home'),
url(r'^results/$', 'search.views.results'),

Nothing is showing up in the {{ query }} space.

解决方案

Ok so the action handling the search in your views.py is supposed to be search but as I suspected in your urls.py you don't call the search method anywhere.

Where do you execute search method?

Urls should be like this:

urlpatterns = patterns('',
url(r'^home/$', 'search.views.home'),
url(r'^results/$', 'search.views.search'),
# or at least have a url for the search view

Note the action attribute in your form

It is action="/results/". This means result view is the one who is supposed to be handling the form. You may also change this to action="/search/" and have your urls like this:

urlpatterns = patterns('',
url(r'^home/$', 'search.views.home'),
url(r'^results/$', 'search.views.results'),
url(r'^search/$', 'search.views.search'),
