Can we loop through django channel layers?
I'm using django channels. I have encountered a problem. I'm trying to loop through different room names to send messages. but I'm getting type error. I don't know if this is possible with django-channels or is it fine to use loop for sending messages in sockets my code. consummers.ProjectConsumer Receive message from WebSocket async def receive(self, text_data): text_data_json = json.loads(text_data) sender = text_data_json['sender'] receiver = text_data_json['receiver'] message = text_data_json['message'] # Send message to room group username = ["admin","main"] for user in username: object = { 'sender':sender, 'receiver': user, 'message':message, } username = user self.room_name = username print("here", self.room_name) self.channel_layer.group_send( self.room_name, { 'type': 'sent', #function name as an event type 'object': object #function parameters as an event object } ) async def sent(self, event): sender = event['object']["sender"] receiver = event['object']["receiver"] message = event['object']["message"] # Send message to WebSocket await self.send(text_data=json.dumps({ 'sender':sender, 'receiver':receiver, 'message':message, })) error: File "/home/aa/gitCodes/clone-beru/4-multiuser_handler/backend/notifications/sockets/consumers.py", line 117, in receive await self.channel_layer.group_send(...

how to make multiple select checkbox with ajax and no button submit
Python 3.9 Django 3.2 I have categories and product , and through a simple form in the template I choose 1 or 2-3 checkboxes and I get the result. How to do it now via ajax and without button 'submit'. I select several product categories and each click on the checkbox is ajax and the next click on the checkbox adds the parameter to the request. it is similar to how you select several parameters in online stores. You have selected 2 parameters and received a filtered list of products I suppose that you need to intercept the sending, store one request in the cache and add a new one to this request <form method="post" id="category-box"> {% csrf_token %} <div class="form-check"> <input class="form-check-input" type="checkbox" name='category' value="{{c.name}}" > <label class="form-check-label" for="{{c.name}}"><a href="{{ c.get_absolute_url }}">{{ c.name }}</a></label> </div> {% endfor %} <button type="submit">Submit</button> </form> -
Will Django always consider an Emoji as 1 character long?
I'm making a Post Reaction model that uses emojis as reactions, and at this point I'm not mapping them to Choices, but instead inserting the utf-8 value (e.g. 😀) directly to the Database (Postgres) as a CharField instance. This made me think which value should I use to the max_length of this field. I know Rust will take emojis as 1 char long, but I'm not sure about how python or Postgres will react. -
Django Forms: How do I use a selected object from dropdown menu?

how do I create a javascript function that changes the html when a form submit button is pushed in django
I can easily update the html when it's not part of the form's submit or button. Or even when it's just a pure button element (rather than an input from a form). However, when I try to append a string to the class "chatGoesHere", nothing happens. The consolealso quickly reloads since the form is going to \send. I'm happy to post my views.py and urls.py, however, I'm pretty sure the issue is inside of my html document below: <p class="chatGoesHere" id="chatGoesHere"> 1st Item! </p> <form action="\send\" method="post"> <input type="text" name="userMessage" /> <input type="submit" value="Send to smallest_steps bot" class="sendButt" id="sendButt" /> </form> <script> var btn = document.getElementById("sendButt"); btn.addEventListener("click", updateChat); function createMenuItem(name) { let li = document.createElement('p'); li.textContent = name; return li; } const td = document.getElementById('chatGoesHere'); td.appendChild(createMenuItem("TEST2")) function updateChat(){ const td = document.getElementById('chatGoesHere'); td.appendChild(createMenuItem("TEST3")) } </script> I'd like it so that every time a user pushes the submit button of the form something gets added to the page without the page reloading. Thank you -
Django window.location not replacing string
I have a javascript function in a django view that is supposed to redirect the user to a different URL that contains a query parameter. When I print out the url before assigning it to window.location, it matches the url pattern as expected. However once I assign the URL to window.location, it seems to append the url to the already existing one instead of replacing it, and thus cannot find the matching url pattern. Javascript function: function downloadEvidence() { var product_review_ids = getProductReviewIDs(); if (product_review_ids === '') { window.alert("Please select at least one deployment.") return; } var url = window.location.href + "download_evidence?productReviewIDs=" + product_review_ids console.log(url); //prints: http://127.0.0.1:8000/access-review-owner/configure/new%20test%20product/download_evidence?productReviewIDs=14 window.location = url; } The url pattern it is supposed to match: urlpatterns = [ path('access-review-owner/configure/<str:product_name>/download_evidence/',views.download_evidence_view, name='download_evidence_view'), ] The view it's supposed to navigate to: @require_http_methods(['GET']) def download_evidence_view(request, product_name): product_id = request.GET.get('productReviewIDs', None) print(product_id) ''' NOTE: Package up evidence here ''' return HttpResponseRedirect(os.environ['BASE_URL']+f'access-review-owner/configure/{product_name}/download_evidence/') The url it's attempting to find when I assign the correct one to window.location: GET http://127.0.0.1:8000/access-review-owner/configure/new%20test%20product/download_evidence/access-review-owner/configure/new%20test%20product/download_evidence/ -
Proper way to construct classes - Django dartCounter project
I was recently starting to do some programming. I figured out how to use Django a couple of days ago. And now I'm trying to integrate some old Python code with it. I created a simple dartCounter. Which is quite easy in a while-loop. However for the new version I want some graphical interface, so I figured I should make some proper classes to interact with without the usage of while loops for the count mechanism. Those classes should be used in the views.py section in Django. The thing is, I think I already made it overcomplex using this method. First I created a class dart_player() class dart_player(): def __init__(self, name): self.name = name self.score = None self.leg = 0 self.thrown_scores = [] def set_start_score(self, start_score): self.score = start_score self.thrown_scores = [] def update_score(self, score): if self.score != None: self.score = self.score - score self.thrown_scores.append(score) else: print("Error score equals 'None' \n") def reverse_score(self, score): if self.score != None: self.score = self.score + score self.thrown_scores = self.thrown_scores[:-1] else: print("Error score equals 'None' \n") def update_leg(self, leg): self.leg = self.leg + leg Next I ended up creating a class dart_match() and within it, the class leg() since the leg is part of … -
Can you access variable attributes in the django template language with other variables?
Let's say I have two variables - User and Fruitlist. User is a model instance, while fruitlist is a list. {% for user in users %} <tr> <td>{{ user.title }} </td> <td>{{ user.text }} </td> {% for fruit in fruitlist %} <td>{{ user.fruit }} </td> {% endfor %} {% endfor %} I'm trying to create a table with the code above where a column is created for each fruit in fruitlist, and that column is filled with the value of an attribute user.fruit (the user model has a field for every fruit which contains a value). Why doesn't the above code work? -
"extends" and "load" in one template (django project) , is this possible . Thanks in advance
I m trying to extend from the base template the navigation and the footer and also to load the static files ,but it doesnt show me any changes when im doing it (When i remove {% extends 'index.html' %} the css is working). I tried with include and it works but its broken - the body is under the footer etc. I tried also with {% block css %} and a lot of other things , but i dont think that is the way of fixing this one.. register_user.html {% extends 'index.html' %} <head> {% load static %} <link rel="stylesheet" href="{% static 'css/register/register.css' %}"> <title>Register - Audi Our Love</title> </head> {% block content %} <h1>Register User</h1> <form method="post">{% csrf_token %} {% for field in register_form %} <p> {{ field.label_tag }} {{ field }} {% if field.help_text %} {{ field.help_text }} {% endif %} {% for error in field.errors %} <p style="color:red;">{{ error }}</p> {% endfor %} {% endfor %} <button type="submit" class="register-button">Register</button> </form> <div> <p>Already have an account ? | <a href="{% url 'login' %}">Login</a></p> </div> {% endblock %} -

CSRF cookie not set - possibly blocked by kubernetes ingress
I use Axios in React and Django Rest Framework with dj-rest-auth. After migrating from GCP to Azure and removing the unmaintained django-rest-auth, I got some new CSRF issues. Initially I removed django-rest-auth and created my own LoginView from Django.contrib.auth.views. Noticed that this also gave the CSRF error in development. So I added dj-rest-auth, which solved my issue locally. Pushed to the AKS, but there the cookie still does not appear. I'm suspecting my ingress to be the problem, which is able to set INGRESSCOOKIE for both my backend and frontend, but no CSRF. I know there's a million tickets about this topic, my Django settings are fine, the set-cookie resopnse header is set. Also use the right axios settings to make sure that if the cookie is there, it's used for requests. The problem is really with the fact that the set-cookie is not coming through, as it is being created in Django. I use an Nginx controller with TLS on a static IP with and have my ingress defined as follows: apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: basic-ingress annotations: kubernetes.io/ingress.class: nginx cert-manager.io/cluster-issuer: letsencrypt-prod nginx.ingress.kubernetes.io/rewrite-target: / kubernetes.io/ingress.allow-http: "true" spec: tls: - hosts: - XXXXX secretName: tls-secret rules: - host: XXXXXXXX … -
Making Model fields for Aligner Tracking that automatically fill other fields by it's total amount and time they need to wear it
I'm trying to build a website for Aligner Tracking. In my Model file, I have length, aligner_number, and time. I want to set it up where let's say I put length (total of aligners) is 10 then my other aligner_number field would generate 10 fields going from 1-10 where each aligner that patient completes we can check off one of the aligner_numbers as complete which is also in the class Treatment. Also, time is the amount of time the patient wears the aligner so let's say they have to change it every 2 weeks. From the length and treatment_number I want it to automatically generate the same number of fields for total aligner numbers with the date being 2 weeks apart. So let's say length is 10 and the aligner_number has a list of aligner numbers 1, 2 , 3, and etc, I want each aligner_number to have a corresponding time_date 2 weeks apart for delivery. So, let's say patient start aligner 1 on November 1st, I want it to automatically generate the time fields to November 14th for Aligner 2, and November 28th for Aligner 3 and etc, so we know the patient needs to start wearing Aligner number … -
Access model field with two keys in template
I am a bit lost. It is been a while since I did some Django and I almost forgot everything about querysets and template. The app is a questionaire for comparing different vendors - hence their products. It is a questionaire with a scoring (best match) to each product. I want to access a specific element in a for loop which has two foreign keys to other classes. Here my model: Model: class Question(models.Model): questionText = models.CharField(max_length=500) class Vendor(models.Model): vendorName = models.CharField(max_length=30, unique=True) class Scoring(models.Model): score = models.IntegerField(default='0', blank=True) questionScoreForKey = models.ForeignKey(Question, null=True, related_name='scorequestion', on_delete=models.SET_NULL) vendorForKey = models.ForeignKey(Vendor, null=True, related_name='scorevendor', on_delete=models.SET_NULL) views.py def index(request): questions = Question.objects.all() vendors = Vendor.objects.all() return render(request, 'compare/index.html', {'questions': questions, 'vendors': vendors}) Template {% for ask in questions %} <tr> <td>{{ ask.questionText }} </td> {% for vend in vendors %} <td id="Vendor_{{ ask.pk }}_{{ vend.pk }}" style> {{ HERE THE SCORE OF THE QUESTION AND VENDOR }} </td> {% endfor %} </tr> {% endfor %} Both keys are existing but I have no clue how to access the score of e. g. the first question for the first vendors. Any hint appreciated. -

Django with LDAP user authentication
I'm working in a Django and LDAP project. For now, with my basic code, a user can login after establishing a Connection with ldap (I'm using ldap3 library) @csrf_exempt def login_view(request): if request.method == "POST": data = json.loads(request.body.decode('utf-8')) cn = data["cn"] password = data["password"] user = Connection(server, 'cn='+cn+',ou=users,dc=syneika,dc=com', password, auto_bind=True) if user is not None: return HttpResponse('authenticated') else: return HttpResponseForbidden('wrong username or password') I am facing a problem when wanting to implement Tokens (JWT), I should Customize authentication backend in Django so I can use the authenticate() function and add tokens. I have a problem understanding the logic there, Django will save a authenticated user in the database but if we change the user password in LDAP? we can always login with the user in the database which is not convenient! Also, how can we customize Django authentication backend to login correctly using LDAP? Thank you -
Python/Django - multiple choice for ForeingKey
I am designing the models for the database that will consist of several apps. It has been decided to add a simple Document Management System to allow infinite documents to be attached to different models. This is the solution that I have thought but I don't know if it there is a better way to do it. Let's say for simplicity 3 models models.py class Contract(models.Model): .... class Invoice(models.Model): .... class Personal_record(models.Model): .... Each model can have multiple documents associated at user discretion for example: "Contract" can have 1 contract_file.pdf and 'n' amendments_to_the_contract.pdf "Invoice" is the only model that can have, in theory, an invoice.pdf per record "Personal_record" is free to the user to attach/upload any file he desires, therefore 'n' records.pdf The solution I thought of is to create another model called Documents that will store all the documents uploaded from any upload form. I would list all the links to the other models and make them blank and use a simple if/else to which type of ForeignKey update. class Documents(models.Model): contract = models.ForeignKey(Contract, on_delete=models.CASCADE,blank=True, null=True) invoice = models.ForeignKey(Invoice, on_delete=models.CASCADE,blank=True, null=True) p_records = models.ForeignKey(Personal_record, on_delete=models.CASCADE,blank=True, null=True) .... Is there a better way to do it? Maybe having only one …
