在 Django 中创建导航栏搜索框的最佳方法是什么？
我希望将一个搜索框集成到显示在每个页面顶部的导航栏中（嘿，在此 StackOverflow 页面顶部有一个我正在谈论的示例）。
也许 nav.html 可能看起来像：
<ul id="menu">
<li><a href="/products"></li>
<li><a href="/service"></li>
<li>{{ nav_search_form.as_p }}</li>
</ul>
也许 forms.py 可能包含：
class NavSearchForm(forms.Form):
query = forms.CharField(max_length=30, required=False)
根据 DRY 原则，我不希望views.py 在每个页面上寻找“查询”，例如：
def ProductsPage(request):
search_form = NavSearchForm()
if request.GET.has_key('query'):
query = request.GET['query'].strip()
# deal with 'Products' here...
def ServicePage(request):
search_form = NavSearchForm()
if request.GET.has_key('query'):
query = request.GET['query'].strip()
# deal with 'Service' here...
我已经并且可以轻松地编写一个页面，该页面将处理搜索查询并显示结果。如何最好地提取搜索词并将用户定向到该搜索页面（返回 HttpResponseRedirect('/results/?query=' + query)）而不剥离每个页面上的 request.GET？
I would like to have a search box integrated into a nav bar that appears on the top of each page (hey, there is an example of what I am talking about up there at the top of this StackOverflow page).
Perhaps the nav.html may look like:
<ul id="menu">
<li><a href="/products"></li>
<li><a href="/service"></li>
<li>{{ nav_search_form.as_p }}</li>
</ul>
Perhaps forms.py may contain:
class NavSearchForm(forms.Form):
query = forms.CharField(max_length=30, required=False)
With the DRY principle I do not want views.py to be looking for a 'query' on every page like:
def ProductsPage(request):
search_form = NavSearchForm()
if request.GET.has_key('query'):
query = request.GET['query'].strip()
# deal with 'Products' here...
def ServicePage(request):
search_form = NavSearchForm()
if request.GET.has_key('query'):
query = request.GET['query'].strip()
# deal with 'Service' here...
I have and can easily program a page that will handle the search query and show results. How do you best extract the search terms and direct the user to that search page (return HttpResponseRedirect('/results/?query=' + query)) without stripping the request.GET on every page?

只需让搜索表单对您的常用搜索 URL 执行 GET 操作即可。
如果您不想硬连线 URL，请使用 URL 反向查找工具...
除非我误解了这个问题，否则听起来您可能认为表单必须获取/发布到加载当前页面的同一 URL。
Just have the search form do a GET on your common search URL.
Use the URL reverse lookup facility if you don't want to hardwire the URL...
Unless I misunderstood the question, it sounds like maybe you were thinking that forms have to get/post to the same URL that loaded the current page.
