Updating instance of model in Django - django

Question

I'm a beginner and trying to make a to-do list app. I want the app to display only the tasks that have not yet been marked completed (by the user).
models.py:
class Task(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
title = models.CharField(max_length=50)
description = models.TextField(blank=True, null=True)
start_date = models.DateTimeField()
end_date = models.DateTimeField()
priority = models.BooleanField(default=True)
completed = models.BooleanField(default=False)
def __str__(self):
return self.title
View:
def task(request):
task = Task.objects.filter(user=request.user, completed=False)
queryset = task.order_by('-start_date')
context = {
'task': queryset,
}
return render(request, 'task-list.html', context)
template:
{% if request.user.is_authenticated %}
<h2>Here is the list of tasks you gotta get done:</h2>
{% if task %}
<ul>
{% for obj in task %}
<li><strong>{{ obj.title }}</strong></li>
<p>{{ obj.description }}</p>
<p>
Start at: {{ obj.start_date }}
</p>
<p>
end at: {{ obj.end_date }}
</p>
{% endfor %}
</ul>
{% else %}
<p>You dont have anything on this list yet!</p>
{% endif %}
{% else %}
<p>Hey! Please login to check your to-do list! click here!</p>
{% endif %}
I want to display an option (a link/button) for the user, which upon clicking would update the instance 'completed' to True (and so the task will no longer be displayed). I would like to use an achor tag as the button. something like
completed
I have created this view:
def task_completed(request, id):
get_task = Task.objects.filter(id=id)
get_task.instance.completed = True
return redirect('task:task-page')
The urls.py:
urlpatterns = [
path('', home, name='home-page'),
path('task', task, name='task-page'),
path('complete', task_completed, name='complete'),
]
upon loading the task-list page, it shows
Reverse for 'complete' not found. 'complete' is not a valid view function or pattern name.
any help would be appreciated!

Please try to set your url as below...
completed
And your url should be...
path('complete/<int:id>', task_completed, name='complete'),
