why does the UserChangeForm model does create an object instead of update it in this case? [django]
I'm using UserChangeForm to update user Form now when I try to send by the request post the function does works but doesn't change the user object but instead, it saves the object like create method does. so, at this moment how can, I change the form object? views.py # Edit Your account @login_required def edit_profile(request, user_slug=None): template_name = 'account/edit_profile.html' if request.method == "POST": request_user = request.user.userprofile user_profile = UserProfile.objects.get(slug=user_slug) form = EditForm(request.POST) if form.is_valid(): form.instance.slug = user_slug form.save() return redirect('account:view_profile', form.instance.slug) return render(request, template_name, {'form': form}) else: form = EditForm() user_profile = UserProfile.objects.get(slug=user_slug) return render(request, template_name, {'form': form}) urls.py urlpatterns = [ path('view-profile/<slug:user_slug>/', views.view_profile, name='view_profile'), # /account/edit-profile/ path('edit-profile/<slug:user_slug>/', views.edit_profile, name='edit_profile'), ] edit_form.html {% extends 'base.html' %} {% block title %} Edit Profile {% endblock %} {% block body %} <div class="edit-form"> <div class="container"> <div class="my-form"> <form method="post"> {% csrf_token %} {% for field in form %} <div class="form-group"> <label for="exampleInputEmail1">{{ field.label_tag }}</label> <p>{{ field }}</p> </div> {% endfor %} <button type="submit" class="btn btn-primary btn-lg">Change Password</button> </form> </div> </div> </div> {% include 'base_footer.html' %} {% endblock %} forms.py # Edit your data except password class EditForm(UserChangeForm): password = None class Meta: model = User fields = ('first_name', 'last_name', 'email') def … -
How to model persons, their addresses and possibly undelivered messages?
I have a database of persons with e-mail addresses like this: from django.db import models class Person(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) class E-Mail-Address(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) address = models.CharField(max_length=256) Now when I send them an e-mail I create an object to record it based on this model: class Sent-E-Mail(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) subject = models.CharField(max_length=120) body = models.TextField() message_id = models.CharField(max_length=10, unique=True) address_used = models.CharField(max_length=256) Note the message_id field. It is a unique identifier for every message, that is used for VERP. So if the e-mail bounces I get that message_id back and can handle it, but this could take several days. In the meantime the Person might update their e-mail-address. How could I change these models to ensure all of the following properties? I know which message had which message_id, so I can identify and resend the bounced message via other means. It is possible to handle situations in which the person updated their e-mail-address between sending the message and receiving the bounce, without marking the new address as invalid. I can tell apart the newly added address and the one actually used to send the last message. I think I have 1. and 3. … -

Why does my ModelForm validation returns False instead of True using Django-simple-captcha
I am trying to implement Django-simple-captcha to somehow prevent my blog from receiving spam comments. Thus, I defined a form and want to implement some validation on the backend to check for human or not... Somehow If I fill out my form and solve the Captcha and try to commit the comment, it always returns false. I guess the bug is in my view. Looking forward to be pointed into the right direction. Thank you. forms.py # Blog Post Comment Form class CommentForm(forms.ModelForm): captcha = CaptchaField() class Meta: model = Comment fields = ('name', 'text', 'captcha') views.py @require_http_methods(['POST']) def post_comment(request): form = CommentForm(request.POST) if form.is_valid(): print('True') gif = request.POST['gif_src'] name = request.POST['name'] text = request.POST['text'] post_id = request.POST['post_id'] # Create new DB entry comment = Comment.objects.create( post_id=post_id, name=name, text=text, gif=gif ) # Query all comments including the new one post = get_object_or_404(Post, id=post_id) return render(request, 'post.html', {'post': post}) else: form = CommentForm() print('False') return render(request, 'post.html', {'form': form}) html <div id="comment-form-ctn"> <h1>Add comment</h1> <form method="POST" class="post-form" id="comment-form-ctn">{% csrf_token %} <div id="form-name-ctn"> <div>Name/Nickname</div> <div id="form-name">{{ form.name }}</div> </div> <div id="form-text">{{ form.text }}</div> <div id="form-captcha">{{ form.captcha }}</div> <div id="buttons-ctn"> <button type="submit" class="comment-button">Comment!</button> </div> </form> </div> -
How to filter post objects in django according to a particular user model field?
I'm currently creating a Social platform with Django. Right now, I'm developing homepage and want to show posts matching a userfield. This is my Post model: class Discussion(models.Model): title = models.CharField(max_length=100) author = models.ForeignKey(Account, on_delete=models.CASCADE) post = models.TextField() date = models.DateTimeField(default=timezone.now) This is user account model: class Account(AbstractBaseUser): email = models.EmailField(verbose_name='email', max_length=60, unique=True) username = models.CharField(max_length=30, unique=True) classid = models.CharField(max_length=10) This is view: @login_required(login_url='login') def home(request): if request.method == 'GET': discussions = Discussion.objects.get(post=Account.classid).order_by('-date') form = PostDiscussionForm() return render(request, 'app/home.html', {'discussions':discussions,'form':form}) else: form = PostDiscussionForm(request.POST) newdisscussion = form.save(commit=False) newdisscussion.author = request.user newdisscussion.save() return redirect('home') I want to show only logged users matching their classid (from user account model) -
CSRF verification failed, 'CSRF token missing or incorrect'
This has been asked many times before and I have read all of those answers, but none of them worked for me so I'd like to try again. When I try to submit a Django form with username and password, I get this error message: 'CSRF token missing or incorrect'. The CSRF token is not missing. Here is where I included it in my form in my .html template: In index.html: <form name="loginform" action="/notes/index/" method="post">{% csrf_token %} {{ form.as_p }} <input type="submit"/> {% for field, errors in form.errors.items %} {{ errors }} {% endfor %} </form> In views.py: class LoginForm(forms.Form): username = forms.EmailField() password = forms.CharField(widget=forms.PasswordInput()) def index(request): if request.method == 'POST': print("Received POST") form = LoginForm(request.POST) if form.is_valid(): print("FORM is Valid") else: print("FORM is NOT VALID") template = loader.get_template('index.html') context = { 'username': 'Benny', 'form': LoginForm(), } return HttpResponse(template.render(context)) I tried adding @ensure_csrf_protect and @csrf_protect, but none of these worked. I also have csrf middleware in settings. I am trying to avoid using @csrf_exempt as this app will go into production down the line. -

How to use multiple Django FBVs in capturing and saving data through Ajax+jQuery
In my Django app, I am using two function views, FV1 and FV2. FV1 is being used to capture data from the database and populate form/formsets. In FV2, I am trying to send serialized data from the page (with the aforesaid data) using Ajax, validate the data in FV2 and save it and finally, receive a confirmation from FV2 as Ajax callback in the page. In the console I can see the serialized data. That validation happens is proven by the fact that if one of the required values is not keyed in, error message captured in the relevant else: segment is passed to the console. However, if all the data is correctly entered and form is submitted, data is not being saved in the respective models. There is no error message either. Given the above scenario, what should be the approach in achieving the goal. It goes without saying that I am missing something big. A guidance to solving the problem will be much appreciated. -

Bad Request (400) even when I have configured the CNAME
I have a basic hacker plan with pythonanywhere and have my domain registered in Namecheap. I am trying to link my domain name with my django app and I get Bad Request (400) upon configuring the CNAME record which is the setup pythonanywhere suggests. Am I missing somthing? The following are the steps I have done: In my "web" tab I have edited the app name as www.gmsolutions.in Have added a CNAME record in NameCheap control panel under my registered domain. Type: CNAME-Record Host: www Value: webapp-xxxxx.pythonanywhere.com (where xxxxx is my app number given by pa) TTL: automatic I am not sure that whether I can make the app number visible or not, that's why shaded it. I had only the CNAME record setup. Is there anything else I should do it? I found no DNS setup errors in my "web" as well. Note: In my allowed hosts, I have added gmsolutions.in. Any hints would be helpful. -
Search by end nested relation django rest framework
I recently picked up an existing project in nodejs, this one is full of all kinds of problems. I decided to reconvert it for more ease with django rest framework, I try to keep the same json structure so as not to interfere with react. For the most part I don't have any problems except for some search with sequelize it searches by the last model to make the inverse relations example : Occurence.findAll({ include: [ { model: TimeSlot, as: 'TimeSlot', include: [ { model: Agenda, as: 'Agenda' } ] }, { model: Monitor, as: 'Monitor', include: [ { model: User, attributes: { exclude: ['password'] } } ], where: { id: req.params.id } } ] }) with django rest framework I didn't find an "efficient" solution to start my search from the end to the beginning and/or replace the structure with to_representation() to display the relations between them. For the total representation I was able to do this but for the search from the last one like the code given with "sequelize" (nodejs code) I don't really see how to do it. class TimeslotsGetOptimizeSerializer(TimeslotsGetSerializer): agenda = serializers.SerializerMethodField(read_only=True) timeslots_occurences = serializers.SerializerMethodField(read_only=True) def get_agenda(self, obj): if obj: agenda = Agendas.objects.filter(timeslotagendas__timeslot_id=obj.id) if agenda: … -
Pipenv virtual environment pulling me into different directories
I have installed pipenv on my machine to run virtual environments. My problem is that when i run pipenv, it keeps pulling me back to a different folder. For example, I build a project in my pycharmprojects folder. I navigate to that project from my terminal. cd pycharmprojects then cd myproject. Then when I run a virtual enrolment in that folder pipenv shell, I get pulled back to /Users/myname/PycharmProjects. This is where my pipfile, piffle.lock and Procfile seem to live as well. I am getting a error when trying to deploy to heroku and I am wondering if it is something to do with this issue based on my virtual environment. The error im getting with deploying to heroku is: !

How to make two gunicorn configs work simultaniously? (Nginx - Gunicorn - Django)
This question might look duplicating, but I can't sort my issue out using the previous answers, sorry. I have a site that is based on Nginx - Gunicorn - Django. Its nginx config is server { listen 80; server_name example.com; ... location / { include proxy_params; proxy_pass http://unix:/home/ks/example-venv/example/example.sock; } } Gunicorn config at /etc/init/gunicorn.conf: description "Gunicorn application server handling example" start on runlevel [2345] stop on runlevel [!2345] respawn setuid ks setgid www-data chdir /home/ks/example-venv/example exec /home/ks/example-venv/bin/gunicorn --workers 3 --bind unix:/home/ks/example-venv/example/example.sock example.wsgi:application Everything works fine.

Django problem overriding all auth Signup forms

Online league player, team, roster, league models
I'm creating league system for online games. My biggest problem is with modeling roster. Every player can be in multiple teams simultaneously. For now i have something like this class Player(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) first_name = models.CharField(max_length=100, blank=True) last_name = models.CharField(max_length=100, blank=True) age = models.IntegerField() rank = models.CharField(max_length=20, choices=RANK_CHOICES); class Team(models.Model): name = models.CharField(max_length=200, null=True) creator = models.ForeignKey(Player, on_delete=models.CASCADE, related_name="creator") team_creation_date = models.DateTimeField(auto_now_add=True, null=True) players = models.ManyToManyField(Player, through="PlayerTeam", related_name="players") class TeamPlayer(models.Model): player = models.ForeignKey(Player,on_delete=models.CASCADE) team = models.ForeignKey(Team,on_delete=models.CASCADE) class League(models.Model): name = models.CharField(max_length=200, null=True) creator = models.ForeignKey(Player, on_delete=models.CASCADE, related_name="league_creator") number_of_teams = models.IntegerField() #number of teams for league to start league_start = models.DateField(null=True) league_end = models.DateField(null=True) class LeagueRoster(models.Model): league = models.ForeignKey(League, on_delete=models.CASCADE, related_name="league") players = models.ManyToManyField(TeamPlayer, related_name="roster_players") When captain/creator of the team is signing team for the league he should choose 5 players from team to create a LeagueRoster. I was thinking about creating roster field in Team model to hold current roster and change it in team panel instead of choosing players before each league. But both those ideas seem like workarounds for me. -
