Saving Data in Multiple Selected Checkbox for Voting System

[Genaro Lubong]

Hello, newbie here, I am currently making our capstone project as a requirement to our course subject, and it is a major subject, while I was in the part of retreiving the selected candidates, I was not about to iterate the vote for those selected on the upper part, just the last selected item/object/candidate, and since it is the major objective of our project, and I am stucked with it and our team will be screwed if I didn't finished it As Soon As Possible, here are my codes:

#views.py

def vote(request):

     selected_candidate = Candidate.objects.get(pk=request.POST.get('candidate'))

     selected_candidate.totalvotes += 1

      selected_candidate.save()

      return redirect('vs:index')

#voting.html

{% if all_candidates %}

     <form action="{% url 'vs:vote' %}" method="post">

         {% csrf_token %}

         {% for organization in all_organizations %}

             {% if all_positions %}

                 <h1>{{ organization.organization }}</h1>

                 {% for position in all_positions %}

                     {% if organization == position.organization %}

                         <h3>{{ position.position }}</h3>

                         <div class="row">

                             {% for candidate in all_candidates %}

                                 {% if position == candidate.position %}

                                     <div class="column">

                                         <div class="col-md-4 col-sm-6 portfolio-item">

                                             <div class="portfolio-link" data-toggle="modal">

                                                 <div class="portfolio-hover">

                                                     <div class="portfolio-hover-content">

                                                             <input type="checkbox" id="candidate{{ forloop.counter }}" class="candidate{{ position.id }} fa fa-check fa-3x"  name="candidate" value="{{ candidate.id }}" />

                                                     </div>

                                                 </div>

                                                 <img src="{{ candidate.picture.url }}" class="img-responsive" />

                                             </div>

                                              <div class="portfolio-caption">

                                                 <h4>{{ candidate.studentid.firstname }} {{ candidate.studentid.middlename }} {{ candidate.studentid.lastname }} {{ candidate.studentid.suffix }}</h4>

                                                 <p class="text-muted">{{ candidate.position }} - {{ candidate.party }}</p>

                                             </div>

                                         </div>

                                     </div>

                                 {% endif %}

                             {% endfor %}

                         </div>

                     {% endif %}

                 {% endfor %}

             {% endif %}

         {% endfor %}

     <div class="intro-text">

             <input type="submit" value="VOTE" class="page-scroll btn btn-xl">

     </div>

      </form>

 {% else %}

     <h2>No Candidates Yet</h2> {% endif %}

#models.py

class Candidate(models.Model):

    studentid = models.OneToOneField(Student, on_delete=models.CASCADE)

    position = models.ForeignKey(Position, on_delete=models.CASCADE)

    party = models.ForeignKey(Party, on_delete=models.CASCADE)

    picture = models.ImageField()

    totalvotes = models.IntegerField(default=0)

    casvotes = models.IntegerField(default=0)

    citvotes = models.IntegerField(default=0)

    coevotes = models.IntegerField(default=0)

    ctevotes = models.IntegerField(default=0)

You provided vote from views.py but vote redirect the user. It does
not use the provided voting.html template.

Also, in my opinion, they are way too many if and for. You have three,
nested, loops. And you are using only a subset of each loop data.
I assume position.organization is a foreign key. So you should be able
to do "{% for position in organization.position_set %}" instead of "{%
if all_position %}{% for position in all_position %}{% if organization
== position.organization %}"
Just the same, you should have a position.candidate_set, with the list
of all candidate in a position.

I hope that help.
