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? I am not sure if this is an error in my django application or my EB configuration. Thanks! If you need any code, I'll post it here -
why i get None instead of the model id in django ImageField path
When attempting to add a new event through the Django admin panel, the image is incorrectly being stored at the path "media/events/None/poster/file.png" instead of the intended path "media/events/{instance.id}/poster/file.png." I have added a print(...) statement to the get_poster_image_path function for testing purposes. : def get_poster_image_path(instance, filename): print(f""" from get_poster_image_path ==================\n type :{type(instance)}\n instance :{instance}\n instance.id :{instance.id}\n instance.name :{instance.name} """) return f'events/{instance.id}/poster/{filename}' class Event(models.Model): name = models.CharField(max_length=50) poster = models.ImageField(upload_to=get_poster_image_path,null=True,blank=True) .... the result: from get_poster_image_path ============================= type :<class 'events.models.Event'> instance :myevent instance.id :None instance.name :myevent -

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 Serializer with Many To Many fileld returns empty list, How to fix it?
I have two models Product and Lessons. I join them in one Product serializer. But I get empty list in lesson fileld.

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
