Why when the id becomes two-digit when filling the rows of the table, I get the error keyword arguments '{'pk': 12}' not found?

Question

Django

The following error takes off from the moment when the 10th record appears in the table. The table looks something like this

I'm going from my html page 'executor.html'

<tbody>
    {% for us in users %}
        <tr>
            <th>{{ us.id }}</th>
            <th>
                {% ifequal us request.user %}
                <a href={% url 'projects' pk=us.id name=us.username %}> {{ us.username }}</a>
                {% else %} {{ us.username }}
                {% endifequal %}
            </th>
            <th>{{ us.email }}</th>
        </tr>
    {% endfor %}
    </tbody>

View for this html

class ExecutorView(TemplateView):
    template_name = 'executor.html'
    context_object_name = 'executors'

    def get_context_data(self, **kwargs):
        context = super(ExecutorView, self).get_context_data(**kwargs)
        users = User.objects.all()
        context['users'] = users
        return context

GO to project.html view which

class ProjectsView(DetailView):
    # model = User
    model = ModuleWork
    template_name = 'projects.html'

    def get_context_data(self, **kwargs):
        context = super(ProjectsView, self).get_context_data(**kwargs)
        modules = ModuleWork.objects.filter(executor=self.kwargs['pk']).order_by('-module_work_data')
        context['name'] = self.kwargs['name']
        context['modules'] = modules
        return context

HTML code

{% block table %}
    <div class="scrollable">
        <table>
            <thead>
            <tr>
                <th>#</th>
                <th>Code project</th>
                <th>Type module</th>
                <th>Data</th>
                <th>Engineer</th>
                <th>Description</th>
                <th>Is produced?</th>
            </tr>
            </thead>
            <tbody>
            {% for module in modules %}
                <tr>
                    <th>{{ module.pk }}</th>
                    <th><a href={% url 'project_module' pk=module.id %}>{{ module.project }}-{{ module.room }}{{ module.room_number }}-
                        {{ module.module.module_symbol }}{{ module.module_number }}</a></th>
                    <th>{{ module.module.module_name }}</th>
                    <th>{{ module.module_work_data }}</th>
                    <th>{{ module.executor }}</th>
                    <th>{{ module.project }}</th>
                    <th>{{ module.module_work_is_produced }}</th>
                </tr>
            {% endfor %}
            </tbody>
        </table>

    </div>

{% endblock %}

And when switching from executor to project, it knocks out an error when clicking on the conditional execotora, which includes lines
with id 10 and higher

In the picture above, for example, if I switch to one author, where lines up to 10 everything works, and where lines above 10 - an error.

Answer 1

url(r'^projects/module/(?P<pk>\d+)/$', 
          ModuleView.as_view(), name='project_module'),
