How can I set JWT at the Frontend with bootstrap html not with react whilst the API is created with Django?
Recently I am studying and building API with Django. I successfully set up the API of authentication system with Django API. I am curious to know that is there any solution to add this JWT with frontend whilst the frontend only with bootstrap designed login form. I don't want to use react or anything like that. Only through Django views is it possible to do? It will be really helpful if there is any way to do. Or if it's required only js I will love to accept but I just want to call the templates login.html file not want to add any react or nodejs. I searched online but everywhere either react or nodejs. Here I am adding the features I am using of JWT in my code #settings.py from datetime import timedelta # for JWT REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.AllowAny', # 'rest_framework.permissions.IsAuthenticated', ], 'DEFAULT_AUTHENTICATION_CLASSES': [ # 'rest_framework.authentication.SessionAuthentication', # 'rest_framework.authentication.TokenAuthentication', 'rest_framework_simplejwt.authentication.JWTAuthentication', ] } SIMPLE_JWT = { 'ACCESS_TOKEN_LIFETIME': timedelta(minutes=360), 'REFRESH_TOKEN_LIFETIME': timedelta(days=90), 'ROTATE_REFRESH_TOKENS': True, 'BLACKLIST_AFTER_ROTATION': True, 'UPDATE_LAST_LOGIN': False, 'ALGORITHM': 'HS256', # 'SIGNING_KEY': settings.SECRET_KEY, 'VERIFYING_KEY': None, 'AUDIENCE': None, 'ISSUER': None, 'JWK_URL': None, 'LEEWAY': 0, 'AUTH_HEADER_TYPES': ('Bearer',), 'AUTH_HEADER_NAME': 'HTTP_AUTHORIZATION', 'USER_ID_FIELD': 'id', 'USER_ID_CLAIM': 'user_id', 'USER_AUTHENTICATION_RULE': 'rest_framework_simplejwt.authentication.default_user_authentication_rule', 'AUTH_TOKEN_CLASSES': ('rest_framework_simplejwt.tokens.AccessToken',), 'TOKEN_TYPE_CLAIM': 'token_type', 'JTI_CLAIM': 'jti', 'SLIDING_TOKEN_REFRESH_EXP_CLAIM': … -

Django and uploading Media files to AWS S3 for users in app to view
this might be a vague question but I am developing an app where users can upload files (mainly videos and pictures). Users can create groups and upload their images to the group and anyone in the group can view these files. I have the AWS S3 configured and working however, Aws recommends to keep the bucket Private. if the bucket is private, is the only way to allow access for users to view content (maybe uploaded by friends VIA pre-signed urls?) is it necessary to even make the bucket private. I see tutorials and they usually have the bucket settings to public. this means that any person that has a hold of the url can access an image. Lets say user 1 uploads to group xyz. only members of xyz should be able to access that image. implementing unique identifiers for images will make it tough for someone to get access to that image but not impossible. would this be the better approach or having django generate signed URLS everytime a user wants to view a certain image? I feel like this is overkill for a photosharing app. are there any other ways to add security? -

What will be the problems with Django app for image processing when deploying?
I am new bee to Django. Never deployed any projects to server. Always worked in localhost. I made Django app, with simple functionalities like: User can add images (CRUD) User can download all the uploaded images with a frame(PNG Frame are already stored, basically I am just masking(merging 2 images) it on user's image will pillow library) I saw many videos on how to deploy your project on server and I already bought domain and VPS(basic one which has 1CPU core, 1GB ram and 20GB SSD) hosting on godaddy. What I am afraid of? Is this server enough for my project(ram and 1cpu core)? Let's say if 100 users request at same time(for image and my code will merge 2 image and serve back) is my server enough to handle all this? I am using Postgresql database. Is postgresql good for such project? I am sorry if this is duplicate question, I honestly don't know what to search for? I am using nginx and Django rest framework for some basic features. -

Django Form submit in foor loop
I tried many things, now I have to ask you. The user has multiple Buttons. My goal is to count every click on a specific button. The specific button is the Field (Field Model).

How to force graphs to stay inside a bootstrap container/card (html, css, plotly, bootstrap, django)?
I'm making a django-based web app that has bootstrap cards with some graphs inside of them. I'm using bootstrap so both the graphs and the cards are responsive; however at some screen sizes, the graphs extend beyond the size of the cards. Is there a way to force everything in a card (or some other container) to say inside the container? Partial html code. Can post the graph code if helpful - it is written in python + plotly. I'm not sure if the problem is with the graphing or with the html/script. I'm also working on posting an image, but the upload is failing :). <div class="container"> <h2 class="pb-2 border-bottom mt-4">Scores for {{ user.username }} </h2> <div class="row mb-4 mt-4"> <div class="col-lg-6"> <div class="card"> <div class="card-body"> <h5 class="card-titler">Result</h5> <p style="color:gray;"> {{last_test_date | safe}}</p> {{score | safe}} <!-- <div class="chart" id="bargraph1", style="height: 150px">--> <div class="chart" id="bargraph1"> <script> var graphs = {{plot1 | safe}} </script> </div> <a href="#" class="card-link text-end p-2">Learn More</a> </div> </div> <div class="col-lg-6"> <div class="card"> <div class="card-body"> <h5 class="card-title">Results Over Time</h5> <br> <!--<div class="chart" id="bargraph2", style="height: 225px">--> <div class="chart" id="bargraph2"> <script> var graphs = {{plot2 | safe}} </script> </div> </div> </div> </div> </div> -
Handle Django MIgrations
I'm working on a Django project with Postgres database using Docker. We are facing some issues in with our migrations, I did not add Django migrations inside .gitignore because I want everyone to have the same database fields and same migrations as well, but every time when someone changes the models or add a new model and push the code with migrations so migrations re not applying in our database as it should be, every time we faced this issue that sometimes ABC key doesn't exist or ABC table doesn't exist, so how can I overcome from it.

Run telegram bot with uWSGI
I have a Django app running on nginx+uWSGI. Inside my Django app there is a Telegram bot (python-telegram-bot). It is a Long Polling bot, not a Webhook one.

Exporting field data in many to many relationships using django-input-output only shows primary key
I am trying to export the data from my database from the django admin page using the django-import-export package. When I export a model, I also want to show the data in a particular field for every object in a many to many relationship. It looks something like this: models.py class Item(models.Model): part_number = models.CharField(max_length=50, unique=True) description = models.CharField(max_length=250, blank=True) def __str__(self): return self.part_number class Bin(models.Model): name = models.CharField(max_length=50, unique=True) items = models.ManyToManyField(Item, blank=True) def __str__(self): return self.name admin.py class ItemResource(ModelResource): class Meta: model = Item fields = ('part_number', 'description') @admin.register(Item) class ItemAdmin(ImportExportModelAdmin): save_as = True resource_class = ItemResource class BinResource(ModelResource): class Meta: model = Bin fields = ('name', 'item__part_number') @admin.register(Item) class ItemAdmin(ImportExportModelAdmin): save_as = True resource_class = BinResource The way I would expect this to work is that if I export Items, I will get a document that has all the part numbers in one column and the description in another. This works just fine. However, I would also expect that when I export Bins, one column would show all the names, and another column would display a list of all the part numbers of the items that are associated with the bin.

Automatically submit a value on click to a form using Javascript/Java in a Django form
I am working on a web app using Django/Python/Javascript/Java. The focal point is a map of the USA. A user should be able to click on a region and the value of that region should automatically query a database and return certain information. Currently, my code produces a const called regionName and the value of regionName is passed automatically as input to the search bar; however, from here a user needs to manually click the 'search' button to submit the form and query the database. As below: onRegionClick: function(event, code){ console.log('event', event, 'code', code); const regionName = map.getRegionName(code); console.log('regionName', regionName); $("#selection").val(regionName); }, }); What I am trying to do with the code is to automatically submit the value of regionName after it is passed to the search bar. Efforts thus far have been similar to the code below. $("#selection") - the form $("#q") - the name of the button $("#selection").on('change', function(){ if ($("#selection").val() === regionName ) { $("#q").click(); } }); This is not producing any errors, but it's not producing any results either. I've tried various substitutes along similar lines such as: .on('input'.. instead of 'change' .submit() instead of .click() I've also have an .autocomplete() method I'm using. I'm not …
