Why this type of error is occured? What you need to know to give my answer?
Please help me someone. I'm a newbie to Django. Thanks in advance.

You are calling the post_save object which is not callable. Try post_save.connect().
from django.db.models.signals import post_save
from django.contrib.auth.models import Group, User
from .models import Student
def student_profile(sender, instance, created, **kwargs):
if created:
group = Group.objects.get(name = 'Student')
instance.groups.add(group)
Student.objects.create(
user = instance,
name = instance.username
)
post_save.connect(student_profile, sender= User)
Or you can also try using receiver decorator:
from django.db.models.signals import post_save
from django.contrib.auth.models import Group, User
from django.dispatch import receiver
from .models import Student
#receiver(post_save, sender=User)
def student_profile(sender, instance, created, **kwargs):
if created:
group = Group.objects.get(name = 'Student')
instance.groups.add(group)
Student.objects.create(
user = instance,
name = instance.username
).save()
Hi There actually i am creating a notes taking app using django. For better ux i have used django ckeditor for providing a good editor to write beautiful and informative notes. I have used django.ckeditor richtextfield for this purpose. Now i want to encrypt the data of this text field so it can be stored safefly. I have used djanog-cryptography package and used encrypt method.
Problem -: When i am retreiving the note_contents in my template its showing nothing.
I am attaching my views and models and settings.py
views.py
from django.shortcuts import render,redirect,get_object_or_404
from django.http import HttpResponse
from django.contrib.auth.decorators import login_required
from . models import UserCreatedNote
from . forms import AddNoteForm
# Create your views here.
#login_required
def notes(request):
if request.method=='POST':
form = AddNoteForm(request.POST)
if form.is_valid():
form_data = form.save(commit=False)
form_data.user = request.user
form_data.save()
notes = UserCreatedNote.objects.filter(user=request.user)
form = AddNoteForm()
context = {'notes': notes,'add_note_form':form}
return render(request,'usernotes.html',context)
notes = UserCreatedNote.objects.filter(user=request.user)
form = AddNoteForm()
context = {'notes': notes,'add_note_form':form}
return render(request,'usernotes.html',context)
#login_required
def edit(request,id):
note = get_object_or_404(UserCreatedNote, pk=id)
if request.method == 'POST':
form = AddNoteForm(request.POST, instance=note)
if form.is_valid():
form_data = form.save(commit=False)
form_data.user = request.user
print(form_data.id)
form_data.save()
form = AddNoteForm(instance=note)
context={'note':note,'u_form':form}
return render(request,'edit_note.html',context)
form = AddNoteForm(instance=note)
context={'note':note,'u_form':form}
return render(request,'edit_note.html',context)
#login_required
def delete(request,id):
note = UserCreatedNote(id=id,user=request.user)
note.delete()
return redirect('/user/notes/')
