I have created a forum website in Django where users can post Questions/Answers and edit them.
After editing the reply I want to redirect the user to the currently edited post page. like if user
edit reply which has been posted on the question with id 4 (which url is (http://127.0.0.1:8000/discussion/4)) then after edited it should redirect to the same URL. After editing, and deleting the reply I am redirecting the user to the forum homepage but I want to redirect to the /discussion/{post_id} URL(which is URL of the particular post on which reply being edited and deleted)
urls.py
app_name = "dashboard"
urlpatterns = [
path('', views.index, name="index"),
path('user_home', views.user_home, name="user_home"),
path('admin_home', views.admin_home, name="admin_home"),
path("forum", views.forum, name="forum"),
path("discussion/<int:myid>", views.discussion, name="discussion"),
path("showallusers", views.show_all_users, name="showallusers"),
path('delete_user/<int:pk>', views.delete_user, name="delete_user"),
path('delete_post/<int:pk>', views.delete_post, name="delete_post"),
path('delete_reply/<int:pk>', views.delete_reply, name="delete_reply"),
path('upload_notes', views.upload_notes, name='upload_notes'),
path('view_mynotes', views.view_mynotes, name='view_mynotes'),
path('delete_mynotes/<int:pk>/', views.delete_mynotes, `name='delete_mynotes'), `

After deleting a reply from a post I want to redirect to the same post.

Currently, after editing the reply, I am redirecting the user to the post home page but I want to redirect to /discussion/{post_id}.
Template code:

{% load crispy_forms_tags %}

<form method="POST">
<div class="form-group">
{% csrf_token %}
<fieldset class="form-group">

<label style="font-size:1rem; font-weight:bold;">Reply Content</label>
{{form|crispy}}
<input type="hidden" name="post_id" value="{{post_id}}">
<div class="form-group">
<button href="" class="btn btn-primary" type="Update">

</button>
</div>
</div>
</form>
</div>
{% endblock body %}
You can redirect it to discussion view with its pk by passing args=[reply.post.id] in edit_reply view.
Try this:
views.py
from django.shortcuts import render, redirect
from django.urls import reverse
def edit_reply(request, pk):
reply = Replie.objects.get(id=pk)
if request.method == 'POST':
form = UpdateReplyForm(request.POST, instance=reply)
if form.is_valid():
form.save()
messages.success(request, "Reply updated successfully!")
return redirect(reverse('dashboard:discussion', args=[reply.post.id]))
else:
form = UpdateReplyForm(instance=reply)
context = {
'form': form
}
return render(request, 'home/edit_reply.html', context)
Note: Forms in django required Form to be the suffix, so it will be better if it changed to PostContentForm and ReplyContentForm from PostContent and ReplyContent respectively.
It must be return f'{self.user} Post' not
return f'{self.user`} Post'
As it is not any field in Replie model.
Note: ForeignKey's names are generally written in its own name and that too in snake_case, it will be better if you change user1 to user in Post model.
For better understanding:
If table name is PizzaTopingCategory so while creating ForeignKey you should name it as pizza_toping_category=models.ForeignKey(PizzaTopingCategory, on_delete=models.CASCADE)
Edit:
You need to find out post_id, so you can send it through:
Try this in the delte_reply view:
def delete_reply(request, pk=None):
reply = Replie.objects.filter(id=pk)
reply_instance = get_object_or_404(Replie,id=pk)
post_pk=reply_instance.post.id
reply.delete()
return redirect(reverse('dashboard:discussion', args=[post_pk]))
For passing pk in discussion view, you should write return redirect(reverse('dashboard:discussion', args=[reply.post.id])) in edit_post view:
views.py
def edit_post(request, pk):
post = Post.objects.get(id=pk)
if request.method == 'POST':
form = UpdatePostForm(request.POST, instance=post)
if form.is_valid():
form.save()
messages.success(request, "Post updated successfully!")
return redirect(reverse('dashboard:discussion', args=[post.id]))
else:
form = UpdatePostForm(instance=post)
context = {
'form': form
}
return render(request, 'home/edit_post.html', context)
I made a model called Annoucement in my models.py file as well as the form for it in my forms.py file. I then made the simple create view for it in my my views.py and made it show on the frontend using the django-crispy-forms package but anytime i load the website, the border of the field appears red showing that there is an error. I have tried checking what the error could be but I am not getting any luck around it.
models.py
class Announcement_by_dean(models.Model):
student_id = models.ManyToManyField(add_students_by_manager)
message = models.TextField()
sent_date = models.DateField(default=datetime.now(), blank=True)
updated_date = models.DateField(auto_now=True, blank=True)
def __str__(self):
return "message sent on "+ str(self.sent_date)
forms.py
class Annoucement_form(ModelForm):
class Meta:
model = Announcement_by_dean
fields = ['student_id', 'message']
views.py
def dean_page(request):
annoucement_list = Announcement_by_dean.objects.all()
if request.method == 'POST':
form = Annoucement_form(request.POST)
if form.is_valid():
form.save()
messages.success(request, _("Message Sent Successfully!!!"))
return redirect('dean_page')
else:
messages.error(request, _("Message Not Sent, Something is Wrong!!!"))
else:
form = Annoucement_form()
messages.error(request, _("Invalid Method!!!"))
context = {"form":form, "annoucement_list":annoucement_list}
return render(request, "dean_page.html", context)
dean_page.html
<!-- Send Announcement -->
<div class="tab-pane fade show" id="nav-announcement" role="tabpanel" aria-labelledby="nav-announcement-tab">
<div class="container mt-4 p-3">
<form action="{% url 'dean_page' %}" method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{form|crispy}}
<button type="submit" class="btn btn-success btn-sm">Submit</button>
</form>
</div>
</div>
I was able to solve the problem, I realised that the indentation of my context and return render was the issue.
views.py
def dean_page(request):
annoucement_list = Announcement_by_dean.objects.all().order_by('-id')
if request.method == 'POST':
form = Annoucement_form(request.POST)
if form.is_valid():
form.save()
messages.success(request, _("Message Sent Successfully!!!"))
return redirect('dean_page')
else:
messages.error(request, _("Message Not Sent, Something is Wrong!!!"))
else:
form = Annoucement_form()
context = {"annoucement_list":annoucement_list, "form":form}
return render(request, "dean_page.html", context)
to
def dean_page(request):
annoucement_list = Announcement_by_dean.objects.all().order_by('-id')
if request.method == 'POST':
form = Annoucement_form(request.POST)
if form.is_valid():
form.save()
messages.success(request, _("Message Sent Successfully!!!"))
return redirect('dean_page')
else:
messages.error(request, _("Message Not Sent, Something is Wrong!!!"))
else:
form = Annoucement_form()
context = {"annoucement_list":annoucement_list, "form":form}
return render(request, "dean_page.html", context)
I'm trying to populate my ModelForm with some of data that I have submitted to previous HTML page which is also ModelForm.
I just want to pass it to another form so it doesn't have to be written twice.
I've tried couple solutions from stackoverflow but they are 6+ years old, kinda outdated and also couldnt come up with solution from django docs https://docs.djangoproject.com/en/2.2/topics/forms/
I have two models, which have same fields which are name and boxid
I need to pass it from first input to second(to populate it).
forms.py
class NewCashierForm(forms.ModelForm):
class Meta:
model = Cashier
fields = ("cashier_company", "cashier_dealer", "cashier_name", "cashier_boxid", "cashier_type", "cashier_package", "cashier_otheritem", "cashier_otheritemserial", "cashier_length", "cashier_promotion", "cashier_amount", "cashier_paymenttype")
labels = {"cashier_company":('Firma'), "cashier_dealer": ('Diler'), "cashier_name":('Ime i prezime'), "cashier_boxid":('Box ID'), "cashier_type":('Tip'), "cashier_package":('Paket'), "cashier_otheritem":('Drugi uredjaj'), "cashier_otheritemserial":('SBU'), "cashier_length":('Dužina'), "cashier_promotion":('Promocija'), "cashier_amount":('Iznos'), "cashier_paymenttype":('Nacin uplate')}
exclude = ['cashier_published']
def save(self, commit=True):
cashier = super(NewCashierForm, self).save(commit=False)
if commit:
cashier.save()
return cashier
class NewPersonForm(forms.ModelForm):
class Meta:
model = Person
fields = {"person_name", "person_adress", "person_phone", "person_boxid"}
labels = {"person_name":('Ime i prezime'), "person_adress":('Adresa'), "person_phone":('Telefon'), "person_boxid":('Box ID')}
def save(self, commit=True):
person = super(NewPersonForm, self).save(commit=False)
if commit:
person.save()
return person
views.py
def addcashier(request):
if request.method == 'GET':
form = NewCashierForm()
else:
form = NewCashierForm(request.POST)
if form.is_valid():
fs = form.save(commit=False)
fs.user = request.user
fs.save()
return redirect('/byauthor')
return render (request, 'main/addcashier.html', {'form':form})
def addperson(request):
if request.method == 'GET':
form = NewPersonForm()
else:
form = NewPersonForm(request.POST)
if form.is_valid():
fs = form.save(commit=False)
fs.user = request.user
fs.save()
return redirect('/addcashier')
return render (request, 'main/addperson.html', {'form':form})

Any help and/or hint is appreciated.
To prepopulate the form, you need to pass an argument initial={} when initializing your form for the GET call. Since you are passing data from one view to another, you should use sessions.
def addperson(request):
if request.method == 'GET':
form = NewPersonForm()
else:
form = NewPersonForm(request.POST)
if form.is_valid():
fs = form.save(commit=False)
fs.user = request.user
fs.save()
request.session["person_form"] = request.POST.dict() #save the form as a dict in request.sessions
return redirect('/addcashier')
return render (request, 'main/addperson.html', {'form':form})
Then in your second view, use this data from sessions to initialize the form.
def addcashier(request):
if request.method == 'GET':
# get the form data from the request.session
form_data = request.session.pop('person_form', {})
box_id = form_data.get("person_boxid")
name = form_data.get("person_name")
form = NewCashierForm(initial={"cashier_name":name, "cashier_boxid":box_id}) # initialize the form with the data
else:
form = NewCashierForm(request.POST)
if form.is_valid():
fs = form.save(commit=False)
fs.user = request.user
fs.save()
return redirect('/byauthor')
return render (request, 'main/addcashier.html', {'form':form})
I'm trying to make register possible on the homepage, so I don't have a seperate URL to handle registration. I'm trying to send the form through get_context_data, however it's not working. Here's my code:
forms.py
class UserRegistrationForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput)
class Meta:
model = User
fields = [
'username',
'password',
]
views.py
class BoxesView(ListView):
template_name = 'polls.html'
def get_context_data(self):
context = super(BoxesView, self).get_context_data()
# login
if self.request.method == 'POST':
form = UserRegistrationForm(self.request.POST or None)
context['form'] = form
if form.is_valid():
username = form.cleaned_data['username']
password = form.cleaned_data['password']
user = User.objects.create_user(username=username, password=password)
user.save()
return redirect('/')
else:
print(form.errors) #doesn't print anything
print(form.non_field_errors()) #doesn't print anything
print('Errors') #doesn't print anything
else:
form = UserRegistrationForm()
context['form'] = form
return context
def get_queryset(self):
pass
base.html
<form action="" enctype="multipart/form-data" method="post">{% csrf_token %}
<div class="registerBox">
{{ form.username }}
{{ form.password }}
<input type="submit" value="register"/>
</div>
</form>
So when I submit the form it gives this error: Method Not Allowed (POST): "POST / HTTP/1.1" 405 0
And it isn't creating a new User. Any idea what the problem is?
EDIT: Tried FormMixin, got this error: The view app.views.BoxesView didn't return an HttpResponse object. It returned None instead.
class BoxesView(ListView):
template_name = 'polls.html'
form_class = UserRegistrationForm
def post(self, request, *args, **kwargs):
form = self.get_form()
if form.is_valid():
username = form.cleaned_data['username']
password = form.cleaned_data['password']
user = User.objects.create_user(username=username, password=password)
user.save()
return redirect('/')
def get_context_data(self):
context = super(BoxesView, self).get_context_data()
context['form'] = self.get_form()
return context
def get_queryset(self):
pass
Ok I see the issue fix the indentation, your if statement should be inside the get_context_data function not outside ;)
You need to add post() method and FormMixin to your CBV like this:
class BoxesView(FormMixin, ListView):
template_name = 'polls.html'
form_class = UserRegistrationForm
# ...
def post(self, request, *args, **kwargs):
form = self.get_form()
if form.is_valid():
# ...
else:
# ...
return render(request, self.template_name, {'data': some_data})
I have this line of code in models.py
#login_required
def user_profile(request):
if request.method == 'POST':
form = UserProfileForm(request.POST, instance=request.user.profile)
if form.is_valid():
form.save()
return HttpResponseRedirect('/accounts/loggedin')
else:
user = request.user
profile = user.profile
form = UserProfileForm(instance=profile)
args = {}
args.update(csrf(request))
args['form'] = form
return render(request, 'profile.tml', args)
and in forms.py
from django import forms
from models import UserProfile
class UserProfileForm(forms.ModelForm):
class Meta:
model = UserProfile
fields = ('address', 'contactnos')
in my loggedin.html
{% extends 'base.html' %}
{% block content %}
<h2> Hi {{ full_name }} you are logged in!</h2>
<p>click here to logout. </p>
<p>Click here to edit your profile info </p>
{% endblock %}
The error is says:
ValueError at /profile/
The view userprofile.views.user_profile didn't return an HttpResponse object.
You haven't accounted for a GET scenario; what happens when the view is not accessed via POST? You return nothing, therefore you get this error.
Return an http.HttpResponse when request.method != 'POST'
Perhaps you meant to un-indent the bottom half else statement.
