I am implementing search on a local Django project: Django 1.11.5, Python
3.6.3, Ubuntu 16.04. My issue is getting the search results onto the
template.
I am using standard CBV for everything else in the site, but for this one I
wrote my own. It uses the same template as my ListView, which shows all
objects fine.
def serp(request):
if request.method == 'GET' and 'searchbox' in request.GET:
q = request.GET.get('searchbox')
query = SearchQuery(q)
object_list = Entry.objects.annotate(
rank=SearchRank(F(
'search_vector'), query)).filter(
search_vector=query).order_by(
'-rank').values_list('title', 'rank')
return render(request, 'serp_list.html', {'object_list': object_list})
Django Debug Toolbar reports everything went as expected. The right
template and view were called, as well as the right db query. I had
previously tested this query in the shell, and it pulls up a 4 element
queryset, as it should.
Even though no search results show on the page, there are 4 instances of
the html that should be surrounding each result and rows=4 loops=1 in the
query plan.
One thing I found curious is that the **mere change** in the variable name
'object_list' to 'resultslist' gave me no db query! I had always thought
variable names didn't matter in Python,
but apparently 'object_list' is virtually a reserved word when it comes to
views (even FBVs) and templates in Django? Here is the template:
<blogpost start>
<article class="blogpost">
<header>
{% for object in object_list %}
<h2><ahref="{{ object.get_absolute_url }}">{{ object.title
}}</a></h2>
<div class="post-info">
<span class="post-date">
<i class="icon-calendar"></i>
<span
class="day">{{object.chron_date}}</span>
<span
class="month">{{object.clock}} </span>
</span>
<span class="submitted"><i class="icon-user-1"></i> by <a href="#"></a></span>
<span class="comments"><i class="icon-chat"></i> <a href="#">22
comments</a></span>
</div>
</header>
<div class="blogpost-content">
{{ object.content|truncatewords:30 }}</div>
<footer class="clearfix">
<div class="tags pull-left"><i
class="icon-tags"></i> <a href="#">tag 1</a>, <a href="#">tag 2</a>, <a
href="#">long tag 3</a></div>
<div class="link pull-right"><i class="icon-link"></i><a href="{{
object.get_absolute_url }}">Read More</a></div>
</footer>
</article>
<!-- blogpost end-->
{% endfor %}
Any assistance in getting the search results to show up greatly appreciated.--

Despite the 99% similarity, this is not identical to my issue in
https://groups.google.com/forum/#!searchin/django-users/template%7Csort:relevance/django-users/o4UKSTBtwyg/cU4JeRJHHgAJ
There I had the for variable 'i' but put the name of the list in the
{{regular variables}}. That is not the issue this time, but clearly I have
trouble grasping the regular and efficient use of Django context and
templates. And yes, I have looked at the docs as well as elsewhere. So if,
in addition to an answer, you can point me to a real clear, simple, step by
step primer on making these two things work together, I would gladly look
at it.
