I have a web page as shown below, the web page able to display the data in the form of a table, I have also implemented the search bar and the page filter and is both working, right now I am try to allow the users to sort the data in ascending order. For example, the customer name will start from A (Airasia) to Z(Zasia) and the part number will start from 1(01232) to 9(999). How do i do that and also at the same time when it is sort in ascending order, both the search bar and the filter pages is also working.
UPDATE: The Url is able to show the stuff that i click on but the data is just not sorting in order as shown in the image below.

CodePudding user response：
in your views.py there is some logic problem because if a user tries to sort your data
by unexisting fields the you will have 500 error.i remove that bugs by doing this.
views.py
@login_required()
def ViewMCO(request):
search_post = request.GET.get('q')
if (search_post is not None) and search_post:
allusername = Photo.objects.filter(Q(reception__icontains=search_post) | Q(partno__icontains=search_post) | Q(
Customername__icontains=search_post) | Q(mcoNum__icontains=search_post) | Q(status__icontains=search_post)
| Q(serialno__icontains=search_post))
if not allusername:
allusername = Photo.objects.all().order_by("-Datetime")
else:
allusername = Photo.objects.all().order_by("-Datetime")
#new important part
part = request.GET.get('sortType')
valid_sort = ["partno","serialno","receptionno","Customername","mcoNum"]
if (part is not None) and part in valid_sort:
allusername = allusername.order_by(part)
page = request.GET.get('page')
paginator = Paginator(allusername, 6)
try:
allusername = paginator.page(page)
except PageNotAnInteger:
allusername = paginator.page(1)

allusername = paginator.page(paginator.num_pages)
context = {'allusername': allusername, 'query': search_post,'order_by':part}
return render(request, 'ViewMCO.html', context)
html
in sort by there is some modification to do.i change the value to value='{{ request.GET.sortType }}' and also i put action="" this means that use the current url.
<div class="sort">
<h5 class="col-md-3">Sort By : </h5>
<div id="sortBlock" class="col-md-9">
<form class="form-inline my-2 my-lg-0" action="" method='GET' value='{{ request.GET.sortType }}'>
<div class="sort">
<input type="radio" id="partno" name="sortType" value="partno">
<label for="partno">Part Number</label>
</div>
<div class="sort">
<input type="radio" id="serialno" name="sortType" value="serialno">
<label for="serialno">Serial Number</label>
</div>
<div class="sort">
<input type="radio" id="receptionno" name="sortType" value="receptionno">
<label for="receptionno">Reception Number</label>
</div>
<div class="sort">
<input type="radio" id="mcoNum" name="sortType" value="mcoNum">
<label for="mcoNum">MCO Number</label>
</div>
<div class="sort">
<input type="radio" id="Customername" name="sortType" value="Customername">
<label for="Customername">Customer Name</label>
</div>
<div class="sort">
<input type="Submit" value="Sort"/>
</div>
</form>
</div>
</div>
now we have to work on pagination(we have to add order_by to the pagination part)
{% if allusername.has_other_pages %}
<ul class="pagination pr-3 mr-1 ml-auto">
{% if allusername.has_previous %}
<li><a href="?q={{ query|urlencode }}&sortType={{ order_by }}&page={{ allusername.previous_page_number }}">«</a></li>
{% else %}
<li class="disabled"><span>«</span></li>
{% endif %}
{% for i in allusername.paginator.page_range %}
{% if allusername.number == i %}
<li class="active"><span>{{ i }} <span class="sr-only">(current)</span></span></li>
{% else %}
<li><a href="?q={{ query|urlencode }}&sortType={{ order_by }}&page={{ i }}">{{ i }}</a></li>
{% endif %}
{% endfor %}
{% if allusername.has_next %}
<li><a href="?q={{ query|urlencode }}&sortType={{ order_by }}&page={{ allusername.next_page_number }}">»</a></li>
{% else %}
<li class="disabled"><span>»</span></li>
{% endif %}
</ul>
{% endif %}
