Question

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!

Answer 1

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.
