get() got an unexpected keyword argument 'title' - django

Question

i want to fetch a blog with a model field which is unique and but when i click on a perticular blog it throw me above mentioned error
here is my views
class Blogs(View):
def get(self, request):
blog_list = Blog.objects.order_by('-joined_date')
return render(request, 'blogs.html',{'blog_list':blog_list})
class ReadBlogs(View):
def get(self, request, title):
readblog = Blog.objects.filter(title=title)
return render(request,'blogs_read.html', {'readblog':readblog})
my model
class Blog(models.Model):
title = models.CharField(max_length=48, blank=False)
urltitle = models.SlugField(max_length=48, blank=False, unique=True)
title_image = models.ImageField(upload_to='blog',blank=True, null=True)
subone = models.CharField(max_length=80, blank=False)
subone_image = models.ImageField(upload_to='blog',blank=True,null=True)
onedes = models.TextField(blank=False)
my html for fetching right blog
<div class="blogs">
{% for blogs in blog_list %}
<a class="products" href="{% url 'blogs:readblog' title=blogs.urltitle %}">
<div class="blog col-4" style="width: 18rem; height:350px">
<img class="img" src="{{ blogs.title_image.url }}" alt="" height="250px" width="100%">
<div class="detail">
<h4 class="title text-center" style="color: #025; font-family:cursive;">{{blogs.title}}</h4>
</div>
</div>
</a>
{% endfor %}
</div>
my url.py
urlpatterns = [
path('blogs/',Blogs.as_view(),name="Blogs"),
path('<slug:title>/',ReadBlogs.as_view(),name="readblog")
]
as you can see mu urltitle is unique slug field so but when i clicked on a particular blog i got above mentioned error any idea what causing error
my template for showing realated field of that blog
<div class="col-11 card">
<div class="blogs">
{% for blog in readblog %}
<h1 class="text-center" style="color: #025; font-family:cursive; margin-top:20px;">{{read.title}}</h1>
{% endfor %}
</div>
</div>

Answer 1

The URL parameter is named title, not url_title:
path('<slug:title>/',ReadBlogs.as_view(),name='readblog')
therefore the .get(…) method should work with title as parameter:
class ReadBlogs(View):
# title &downarrow;
def get(self, request, title):
blog = Blog.objects.filter(title=title)
return render(request,'blogs_read.html',{'blog':blog})
Here blog is a collection of zero, one, or more blogs. If you want to pass a single Blog object, you should fetch a single object, for example with get_object_or_404:
from django.shortcuts import get_object_or_404
class ReadBlogs(View):
def get(self, request, title):
blog = get_object_or_404(Blog, title=title)
return render(request,'blogs_read.html',{'blog':blog})
It might also make more sense to work with a DetailView [Django-doc] to automatically render the item properly:
from django.shortcuts import get_object_or_404
from django.views.generic.detail import DetailView
class ReadBlogs(DetailView):
model = Blog
template_name = 'blogs_read.html'
def get_object(self, *args, **kwargs):
return get_object_or_404(Blog, title=self.kwargs['title'])

Answer 2

template
{% url 'blogs:readblog' title=blogs.urltitle %}
here, you pass title=urltitle, so you actually pass urltitle!
views
# your-code | wrong
class ReadBlogs(View):
def get(self, request, title):
# ======== HERE, TITLE IS ACTUALLY urltitle! ==================
readblog = Blog.objects.filter(title=title)
return render(request,'blogs_read.html', {'readblog':readblog})
# correct
class ReadBlogs(View):
def get(self, request, title):
readblog = Blog.objects.filter(urltitle = title)
return render(request,'blogs_read.html', {'readblog':readblog})
