Hello everybody! I want to search in a ManyToManyField in the DetailView. It works fine if a user with the same query exist, but if there isn't a user, i get page not found error.

models.py:

class agents(models.Model):      agent_type = models.ForeignKey(types, on_delete=models.SET_NULL, blank=True, null=True)      name = models.CharField(max_length=100)      users = models.ManyToManyField(user_models.users, through='user_agent')

views.py:

class AgentDetailView(LoginRequiredMixin, generic.DetailView):      model = models.agents      template_name = 'agent/agent_detail.html'        def get_queryset(self):          query = self.request.GET.get('q')          if query:              return models.agents.objects.filter(Q(users__user__first_name__contains=query)                                                  | Q(users__user__last_name__contains=query)                                                  | Q(users__id_number__contains=query)                                                  | Q(users__mobile__contains=query))          else:              return models.agents.objects.all()

agent_detail.html:

<h1>name: {{ agents.name }}</h1>      <form method="GET" action="" id="searchform">          <input class="searchfield" id="searchbox" name="q" type="text" placeholder="Search..."/>          <button name="search" type="submit" value="{{ request.GET.q }}">Search</button>      </form>      {% if agents.users %}          <p><strong>Users:</strong>              <br>              {% for users in agents.users.all %}                  <li>{{ users }}</li>                  <hr>              {% endfor %}          </p>      {% else %}          <p>There are no user for this agent in database.</p>      {% endif %}
