What is the best way to do a nav bar search box in Django?

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?

Solution

  • Just have the search form do a GET on your common search URL. 

    <form action="/search/" method="get">
...
</form>

    Use the URL reverse lookup facility if you don't want to hardwire the URL...

    <form action="{% url my-search-view %}" method="get">
...
</form>

    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.
