why my django slug is not working properly - django

Question

I want to allow user to search in database for the topic. and show the topic name in url.
I already created slug field in database but when i am trying to fetch the data from the database the url is not showing correctly.
url is showing:
http://127.0.0.1:8000/topic/<slug:topicname>/
what I want to show:
http://127.0.0.1:8000/topic/introduction-to-python/
My urls.py file
from django.urls import path
from . import views
urlpatterns = [
path('', views.apphome),
path('topic/<slug:topicname>/', views.searchtopic, name = 'searchtopic'),
]
My model for the project
class blogposts(models.Model):
topic = models.CharField(max_length = 200)
slug = models.SlugField(max_length = 150, null=True, blank = True)
post = models.TextField(max_length = 500)
def __str__(self):
return self.topic
This is my view
def searchtopic(request,topicname):
if request.method == 'POST':
topicname = request.POST.get('searchtopicname')
mypost = mypostlist.objects.filter(slug = topicname)
context = {
'mypost':mypost,
}
return render(request, 'blog/result.html',context)
My form for searching topic
<form action="topic/<slug:topicname>/" method="POST">
{% csrf_token %}
<input type="search" placeholder="Search topics or keywords" name="searchtopicname">
<button type="submit">Search</button>
</form>

Answer 1

You can use 'GET' method insted of 'POST'
replace form with:
<form action="{%url 'searchtopic' %}" method="GET">
{% csrf_token %}
<input type="search" placeholder="Search topics or keywords" name="searchtopicname">
<button type="submit">Search</button>
</form>
replace urls.py:
urlpatterns = [
path('', views.apphome),
path('topic/', views.searchtopic, name = 'searchtopic'),
]
replace views:
def searchtopic(request):
if request.method == 'GET':
topicname = request.GET['searchtopicname']
mypost = mypostlist.objects.filter(slug = topicname)
context = {
'mypost':mypost,
}
return render(request, 'blog/result.html',context)
