trouble in admin pages showing name in select for foreign key instead of id
I have two models Client and Master. Master has a foreign key to client. I am trying to get the select for the foreign key to display the name in the admin pages but getting an error. Here is the client model class Client(models.Model): id = models.BigAutoField(primary_key=True), name = models.CharField(max_length=200, blank=False, null=True) clientEmail = models.CharField(max_length=200, blank=False, null=True) clientPhone = models.CharField(max_length=200, blank=False, null=True) clientCompany = models.CharField(max_length=200, blank=False, null=True) def __str__(self): and here is an abbreviated Master class Master(models.Model): id = models.BigAutoField(primary_key = True) client = models.ForeignKey(Client, on_delete=models.CASCADE,null=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) user_metadata = models.JSONField(max_length=500, null=True, blank=True) user_id = models.CharField(max_length=500, blank=False, null = True) user_name = models.CharField(max_length=500, blank=False, null = True) #abbreviated def __str__(self): return self.user_name def c_name(self): return self.client.name and the admin.py class MasterDataAdmin(admin.ModelAdmin): list_display = ( 'id', 'c_name','user_name', 'account_status') admin.site.register(Master, MasterDataAdmin) Now when I go to the Master in admin pages I get...

How to change user password from Cognito Forgot Password using Lambda and triggers?
I'm building an SSO process to integrate an app with Cognito. For that I'm using Django (the app), Mozilla OIDC (for integration with Cognito) and AWS Cognito. I'm able to migrate users from the already existing app to Cognito User Pool. I need to contemplate the situation where a user clicks on "Forgot Password", which should trigger a Lambda, and allows me to update the user's password (hashing it) into the Database by writing the lambda_handler code. Now I don't understand how to achieve this. More specifically, the flow and which trigger to use. So far, when a user clicks on Forgot Password, it sends an email with a confirmation code, which the user has to enter along with the new password and new password confirmation. I need that when the user CONFIRMS that new password, I would capture that event and that new password I would hash it and update the database. All the hashing and updating the database, I know how to do. This is what I'm doing: Push a docker image that contains Django, boto3 and psycopg2 to an AWS ECR. This image gets pulled up when the lambda gets triggered (I think there are generic triggers … -

Django SSL Operations Causing Slow API Response - How to Improve Performance?
I am a beginner at Django , I made a read request to an Api endpoint in a django appliation, it takes about 15 seconds to retrieve its content, which is a very long time, I profilled the django application and got this back, , I know it is related to SSL operations, What can I do to reduce the SSL-related latency and improve the response time of my Django application when making API requests over SSL? What I've Tried: I profiled my Django application using a profilling module and found that a significant amount of time is spent on SSL operations when making API requests to the server. I noticed that SSL handshakes and some other SSL related functions are taking a long time. I expected the API requests to be processed much faster, like very much faster, 15 seconds is too -

Deploy Django with TailwindCSS on Elastic Beanstalk
Good day, I recently deployed a Django project to Elastic Beanstalk using the following tutorial: https://testdriven.io/blog/django-elastic-beanstalk/ This is the website: http://gmoonline4-dev.us-east-1.elasticbeanstalk.com/ The website works fine, including the admin and database, except for the CSS, which gives an error This template loads properly in development, but you can see the end product after deployment. I tried including the container_command "python3 manage.py tailwind start", but this fails the deployment. Can anyone assist me with this?

Django Python+Ajax : how to update variable from frontend to back end? My ajax function isn't working
When the user submits this form I want to save the rgb color code as a variable to be stored on the back end (using django), so whenever the card is loaded (the colour picked on this page) will be loaded. I asked GPT, which suggested using ajax (I've never used it before). This is a snippet from my js : function updateSetColor(color) { console.log(color); $.ajax({ type: "POST", url: "/Flashcard/", beforeSend: function(xhr, settings) { xhr.setRequestHeader("X-CSRFToken", getCookie("csrftoken")); }, data: { color: color }, error: function(error) { console.log("Error updating color"); }, cache: false, }); } This is a snippet from my view that uses the color variable sent from the data : def flashcard(request): form = Flashcard_verif(request.POST) if request.method == "POST" and form.is_valid() and request.accepts('main/Flashcard.html'): print(request.POST) color = request.POST.get("color") # Get the color from the AJAX request print(color) As you can see I've got the console to output the color picked by the user and on the backend I've got the server to output the color that should've been recieved. The output from the console is correct but the output from the server is 'None'. I suspect its due to the ajax function. Any help would be appreciated or new ways of … -

Django: How to enable app usage for different societies
I have a django project that has many apps. There is a core app that has all the main models that other secondary apps will use. One model in the core app is called SocietyEntity: class SocietyEntity(models.Model): id = models.AutoField(primary_key=True) referenceName = models.CharField(max_length=200, verbose_name="Nombre") members = models.ManyToManyField(get_user_model()) administrator = models.ForeignKey(get_user_model(), on_delete=models.CASCADE, verbose_name="Administrator") As shown, the societies can have one o more users as members. What I want to achieve is some kind of relation between societies and the other secondary apps of the project, that enable that society to make use of the app. Something like a manytomany kind of relation between SocietyEntity and app names? I'm not sure but I think I need some way to relate societies to apps, if that is even possible. If a society doesn't have permission to use an app, this shouldn't be listed in the admin interface for example. Any suggestion is well received! Thanks -

How can I see the values of a ManyToMany field based on a Foreign key value in Django Admin Panel?
I am making a Django app for multiple choice question-answer exam. I have created a Subject, Question and Exam model as below. class Subject(models.Model): subject_name = models.CharField(max_length=200, blank=False) subject_code = models.IntegerField(blank=False) class Question(models.Model): subject = models.ForeignKey(Subject, on_delete=models.CASCADE) question_name = models.CharField(max_length=200,null=True) class Exam(models.Model): subject = models.ForeignKey(Subject, on_delete=models.CASCADE) questions = models.ManyToManyField(Question) date_of_exam = models.DateField(blank=False) users = models.ManyToManyField(CustomUser) Here in Question I am connecting subject by Foreign Key relation. In Exam I have subject as Foreign key and questions as ManyToMany relation from Question model. I want to create exam from admin panel. I want that when I select a subject only the questions of that subject should be displayed in the manytomany field to select from (As questions have foreign key of subject I think it should be possible). (I want to do this from admin panel only and not from a template.) How can I achieve this? Any suggetion is very much appreciated. Thanks in advance for the suggestions!! :) -
What should I know before shifting from Django to Wagtail
I am python programmer ,I know how django works but I'm trying to move to Wagtail. I seem not to understand about how Wagtail works , it mixes Models with templates and I also find out that it doesn't use any views ,this goes against how django works. Can you please explain to me what is a Wagtail Page exactly. I know its sort of a model but I don't seem to understand how it works. I would also like to know how do I get to use Wagtail Pages to render different data depending on data in the database lets say images of Users in the database. Also ,do I have to create a Page for everything eg If I want to create a User Model or Profile Model ,does it have to be a Page also. Please Help. I tried to actually to use Wagtail docs to create a web app but I don't seem to be in control .Wagtail doesn't have an views so i don't know how i can handle the requests in my own way then send the response of my own ,lets say JSON data. -
FastAPI Endpoint List as parameter not working
I I want to create an endpoint that receives a list of strings, which will be called and used as assets in the endpoint function. The endpoint http://localhost:8000/api/v1/equipments works correctly.

I'm pretty sure that Authorization has no role to play in the problem. -

I am relatively new to this, and was not able to find out why the message is never sent, when the task is being run asynchronously. Is this not possible to achieve, or what is it that I am missing? I am aware that I could use Celery for this, though I would prefer not to unless this cannot be done with Django-Q. Here is the setup: #views.py def testview(request, uuid): task_id = async_task(dummy_task, uuid) event_triger(uuid, task_id) # This message shows up. def event_triger(uuid, message): channel_layer = get_channel_layer() async_to_sync(channel_layer.group_send)( uuid, { 'type': 'send_message_to_frontend', 'message': message } ) def dummy_task(uuid): for i in range(3): event_triger(uuid, "") time.sleep(3) The consumers.py file has the following: class NotificationConsumer(WebsocketConsumer): def connect(self): self.uuid = self.scope["url_route"]["kwargs"]["uuid"] async_to_sync(self.channel_layer.group_add)( self.uuid, self.channel_name ) self.accept() self.send(text_data = json.dumps({ "type": "est", "msg": self.uuid, "channel": self.channel_name })) def disconnect(self, code): async_to_sync(self.channel_layer.group_discard)( self.uuid, self.channel_name ) print("DISCONNECED CODE: ",code) def send_message_to_frontend(self,event): …
