Exception Type: NoReverseMatch - Django - html

Question

after researching for hours I cannot get rid of this error, I hope someone can help me.
Models:
class Puja(models.Model):
seller = models.OneToOneField(Seller, on_delete=models.CASCADE)
user = models.OneToOneField(User, on_delete=models.CASCADE, blank=True,null=True)
title = models.CharField(max_length=100)
video = models.FileField(blank=True)
photo = models.ImageField(blank=True)
published_date = models.DateTimeField("Published: ",default=timezone.now())
bidding_end = models.DateTimeField()
starting_price = models.IntegerField(default=1)
#slug = models.SlugField(null=True)
def __str__(self):
return str(self.title)
#def get_absolute_url(self):
# return reverse('bidding_list_detail', args=[str(self.id)])
#slug time
def get_absolute_url(self):
return reverse('bidding_list_detail',args={'id': self.id})
Views:
class bidding_list(ListView):
model = Puja
template_name = 'bidding_templates/bidding_list.html'
"""return render(request= request,
template_name='bidding_templates/bidding_list.html',
context = {"Pujas": Puja.objects.all})"""
class bidding_list_detail(DetailView):
model = Puja
template_name = 'bidding_templates/bidding_list_detail.html'
urls:
path('admin/', admin.site.urls),
path("bidding_list/", bidding_list.as_view(), name="bidding_list"),
path('<int:pk>', bidding_list_detail.as_view(), name='bidding_list_detail'),
admin:
class PujaAdmin(admin.ModelAdmin):
list_display = ('seller','title','video','photo','published_date','bidding_end','starting_price')
admin.site.register(Puja,PujaAdmin)
template 1:
{% extends 'header.html' %}
{% block content %}
<h1>Pujas</h1>
{% for Puja in object_list %} <!--object_list-->
<ul>
<li> {{ Puja.title }} </li>
</ul>
{% endfor %}
{% endblock %}
template 2:
{% extends 'header.html' %}
{% block content %}
<div>
<h2>{{ object.title }}</h2>
<p>{{ object.seller }}</p>
</div>
{% endblock %}
Note that, whenever I remove <a href="{{ Puja.get_absolute_url }}"> from the first template, the objects "puja" in the model get properly displayed on the template, but I cannot access them. They normally exist on the admin panel, but not displayed on the website directly.
Thank you very much on advance and stay healthy.
edit 1: Here is the urls.py directly from the app created by django. To be more specific, I created after the project a new app called "main" in which I programmed all the project, including all the code on this question except the edit.
from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
#from django.config import settings
#from django.config.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('main.urls')),
#path('', include('model.urls')),
#path('', include('blog.urls')),
#path('', include('photo.urls')),
#path('', include('video.urls')),
] # +static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += staticfiles_urlpatterns()
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Answer 1

I guess the problem is this line - return reverse('bidding_list_detail',args={'id': self.id}), you are passing id as a string but trying to match with int in url.Try following return reverse ('bidding_list_detail',args=[self.id])
