How to modify the id field in django-rest-framework-simplejwt?
I have a custom token serializer: from rest_framework_simplejwt.serializers import TokenObtainPairSerializer class TokenObtainPairWithoutPasswordSerializer(TokenObtainPairSerializer): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['password'].required = False def validate(self, attrs): attrs.update({'password': ''}) return super(TokenObtainPairWithoutPasswordSerializer, self).validate(attrs) This worked but now I'd like to change the id -field of my User to be userId and after that I can't get tokens anymore because it is searching for a field id. There must be some pretty simple way to modify this? -

How to set custom primary keys of different models as foreign key and migrate to mysql properly in django?
I created this model for my django project and connected it with mysql. I created customerid as the primary key in the Customer model and used it as a foreign key in the cart to represent the owner. There should not be an id field since django does not create one when primary key is true. Whenever I try to migrate the model, it errors "Cannot drop 'id': needed in a foreign key constraint 'api_cart_owner_id_c65befd7_fk_api_customer_id' of table 'api_cart'"). I tried fake migration but that created an unwanted id field in the mysql schema. And if I leave it like that and make a post request with a customerid I get this error "Incorrect integer value: '' for column 'owner_id' at row 1". I suppose that owner_id is looking for id field from customer model instead of customerid. I believe I have not set the cart model correctly. How do I represent the customerid and itemid (custom primary keys of different model) as a foreign key for the cart model and migrate it properly? class Item(models.Model): itemid = models.TextField(primary_key=True) name = models.TextField() price = models.FloatField() quantity = models.IntegerField() ordered = models.IntegerField(default=0) def __str__(self): return self.name class Customer(models.Model): customerid = models.TextField(primary_key=True) name … -

Source specified in Javascript not showing up in Django template
Maybe this is a really dumb question, but I'm learning Javascript and Django and can't figure it out. I've spent a few hours on this and maybe it's a syntax error or something else. I want to specify the source of an image in javascript and then display the image in Django HTML template. It's not working, even with simple images Here is my javascript: $(document).ready(function() { var image = document.getElementById("image").src('https://res.cloudinary.com/.../{{ object.id}}'); } Here is my image info: <img src="#" id="image" class="mx-auto" width="250px" onerror='this.onerror = null; this.src="https://res.cloudinary.com/.../image.jpg"'/> What am I doing wrong? It's definitely not working - the image is not showing up even when it exists. I either get the default image or no image. -

docker + nginx http requests not working in browsers
I have a AWS EC2 instance running Linux with docker containers running gunicorn/django and an nginx reverse proxy. I don't want it to redirect to https at the moment. When I try to reach the url by typing out http://url.com in the browser it seems to automatically change to https://url.com and gives me ERR_CONNECTION_REFUSED. The request doesn't show up at all in the nginx access_log. But when I try to reach it with curl I get a normal response and it does show up in the nginx access_log. I have ascertained that the django security middleware is not the cause as the HSTS options are disabled. I've tried clearing the browser cache and deleting the domain from the chrome security policies. nginx config: upstream django_server { server app:8001 fail_timeout=0; } server { listen 80; server_name url.com www.url.com; client_max_body_size 4G; charset utf-8; keepalive_timeout 5; location /static/ { root /usr/share/nginx/sdev/; expires 30d; } location / { proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; if (!-f $request_filename) { proxy_pass http://django_server; break; } } } What am I overlooking? -

How to modify nav-pills to limit the number of pages to display

Load Django Objects Quicker
so I'm working on a Django news aggregator project. A main aspect of the project involves me fetching reddit and twitter posts through their respective APIs, saving the post data to a post model, then loading those model objects onto the page. This is what I would prefer to do over fetching the data and displaying it directly through the response objects. Right now, I have two separate timelines of reddit posts, and twitters posts, adjacent to each other on the page. Last time I loaded the page, it took a really long time. This is what the page looks like btw: I was hoping someone could explain to me how I can get my page to load faster, and also how to integrate timeline/newsfeed functionality well. Lets say I have over 1500 post objects in my database, I don't want to load all 1500 on the page at one time. I'd like to load like the first 100, then if someone scrolls down the page enough, the next 100 become loaded, etc. Is there an easy/efficient way to go about this? Thanks -
