Is nginx required to deploy a gatsby front end beside a django REST backend?
I'm currently trying to deploy a Django REST backend and a React/Gatsby frontend to Heroku (using the steps outlined in this article https://dev.to/mdrhmn/deploying-react-django-app-using-heroku-2gfa), and I'm having some issues sending requests from the front end to the back end. GET Instruction useEffect(() => { fetch('http://127.0.0.1:8000/ljwe/symbol/?freq=monthly&symbol_id=1') .then(res => res.json()) .then(data => setOptions(data)) .catch((err) => {console.error(err)}) }, []); CORS_ALLOW_ALL_ORIGINS = True in settings.py "proxy": "http://localhost:8000" in both gatsby-config.js and package.json files Locally, everything works fine and the database is successfully queried, returning the proper information Unfortunately, when I push my changes to Heroku, the data is no longer displayed. I'm using the following build packs: heroku/node.js https://github.com/heroku/heroku-buildpack-static heroku/python When I run heroku run psql <heroku_app> I can query the app's database and see relevant entries in the tables. In addition, when I manually enter my API endpoints on the Heroku-hosted version, they work as intended. My Heroku logs also seem to show the request going through fine. Browser Console Output -

Connection refused when accessing Nginx container from React container

Why isn't Django Rest Framework Token Authentication working?
I am currently using Django rest framework and trying to implement a Token Authentication system. Currently, my settings.py looks like this: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.TokenAuthentication' ] } and rest_framework.authtoken is in installed_apps. My urls.py looks like this: urlpatterns = [ ... url('^v1/users/$', views.users_view), ... ] My views.py looks like this: @authentication_classes((TokenAuthentication,)) @api_view(['PUT', 'POST']) def users_view(request): ... I'm working in postman to test the API and regardless of whether I put the token in the Bearer Token authorization field, the API works as intended. What do I need to change for the token authentication to work as intended? -

Django - Can't read media files
I'm using Django to create a website where you can upload an image on that website and check if the image contains Moire pattern. Here is the project structure: In file settings.py, I specified the following directory for media files: MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' and in file views.py, I implemented the API that will receive the image and detect moire pattern like this: from django.core.files.storage import default_storage def index(request): if request.method == 'POST': f = request.FILES['sentFile'] response = {} fname = 'pic.jpg' fname2 = default_storage.save(fname, f) file_url = default_storage.url(fname2) image = Image.open(file_url) pred_label = moire_detect(image) response['label'] = pred_label return render(request, 'frontpage.html', response) else: return render(request, 'frontpage.html') However, when I try to open the image using Image module of Pillow, I got this error "No such file or directory: '/media/pic_O1TOyCK.jpg'". I don't really understand what is happening here, because the path is correct. Any help would be really appreciated. -
Add total pages to the Django Rest Framework response when using pagination
At the Django Rest Framework Documentation you can add pagination according to the document at this link: https://www.django-rest-framework.org/api-guide/pagination/#modifying-the-pagination-style class StandardResultsSetPagination(PageNumberPagination): page_size = 100 page_size_query_param = 'page_size' max_page_size = 1000 and the response will look like: HTTP 200 OK { "count": 1023 "next": "https://api.example.org/accounts/?page=5", "previous": "https://api.example.org/accounts/?page=3", "results": [ … ] } How can I add "total_pages" to the response?

Unable to get records using Django ORM
Problem: Trying to get a record using Django ORM, from a table that contains a JSON field, I'm using the following line: test_object = House.objects.get(id=301) Error TypeError: the JSON object must be str, bytes or bytearray, not dict Possible issue Noticed that a previous developer updated the format of the JSON field in the table, seems that JSON had a bad format. Script used to format the JSON column: for i in data: jsonstring = json.dumps(i.result) new_clear = jsonstring.replace("\\", "") new_clear = jsonstring.replace("NaN", "null") i.result = json.loads(new_clear) i.save() Comments In pgAdmin the JSON field looks good and it is formatted properly, see a partial copy of the JSON below: {"owner_id": 45897, "first_name": "John", "last_name": "DNC", "estate_id": 3201, "sale_date": "3/18/19", "property_street": "123 main st", "property_city": "Miami", "property_state": "FL", "property_zipcode": 33125, "Input_First_Name": "John", "Input_Last_Name": "DNC"} I would like to know how to deal with this JSON field in order to query the object.

Celery/redis tasks don't always complete - not sure why or how to fit it
I am running celery v 4.0.3/redis v 4.09 in a django v 3.0.1 application (Python v 3.6.9). I am also using face_recognition in a celery task find_faces to find faces in the images I have uploaded to the application, among other image processing celery tasks. There are no issues processing five or fewer image files in that all the image processing celery tasks complete successfully. When I have the image process tasks (including find_faces) iterate over 100 images there are 10-30 images where the find_faces task does not complete. When I use flower v0.9.7 to take a look at the celery tasks, I see that the find_faces task status is "started" for those images that did not complete. All the other images have find_faces task status as "success". The status of these "started" tasks never changes, and there are no errors or exceptions reported. I can then run the image processing tasks, including the find_faces task, on each of these images individually, and the task status is "success". These results do not change if I run celery as a daemon or locally, or if I run the django app using wsgi and apache or runserver. Flower also reports that retries … -
How to sum annotation values by groupby in Django

Django tests are not outputting Messages in template rendering
I can't seem to get a unit test to check if Messages are rendering properly in my template. As per my template, I'm not getting any output where the messages should be listed. I'm using pytest 6.2.5 and Django 3.1.13 if that's helpful. Here is my test code: import pytest from django.contrib import messages from django.contrib.messages.middleware import MessageMiddleware from django.contrib.sessions.middleware import SessionMiddleware from django.test import RequestFactory from django.views.generic import TemplateView pytestmark = pytest.mark.django_db class TestBaseTemplate: def test_messages_middleware(self): request = RequestFactory().get("/") view = TemplateView.as_view(template_name="base.html") middleware1 = SessionMiddleware() middleware1.process_request(request) request.session.save() middleware2 = MessageMiddleware() middleware2.process_request(request) foobar_msg = "Hello, world!" messages.info(request, foobar_msg) request.session.save() response = view(request) response.render() content = response.content.decode("utf-8") # This assert fails assert foobar_msg in content My message block in the template (base.html) is straight-forward (and does work in views that send messages): {% if messages %} <div> {% for message in messages %} <p>{{ message }}</p> {% endfor %} </div> {% endif %} I can see through debugging that before you get to rendering the response that the "Hello, world!" message is being noted properly in the request via the Session/Message middleware, it's just not being rendered in the response.

Django 3.2 - login form on homepage
I’m fairly new to Djanjo, and I have got a simple app working, however all the tutorials I can find have a “login” link on the homepage which redirects to a login page, this seems unnecessary ( at least for what i want ), I’d prefer to have the login page on the homepage, so the user can log straight in from there. I found some very old questions on here where people asking same/similar, but the answers seem old and perhaps even overly complicated. I think what I need to do, is to somehow set my urls.cfg in config/ for ‘’ to point to the built in auth view, but I cannot find a clear example of that. I’d like to achieve it with minimal customization. Just looking for an upto date pointer in the right direction for latest Django 3 please, if anyone can help me better understand what I should do. -
creating a delay in an html render in django?
I'm making a chatbot for practice in Django. When the user sends a message, the chatbot responds a few seconds later. I can display the text of the user and chatbot be in the template below. I'm unsure of how to create this delay. I understand that using javascript we can use the timeout() function: setTimeout(() => { console.log("World!"); }, 2000); Currently this is what I have: {% extends 'chat.html' %} {% block chatStream %} {% for item in chat %} <p> <b>user:</b> {{item.user}} <br> <b>bot:</b> {{item.bot}} <br> </p> {% endfor %} <form action="/send/" method = "post">{% csrf_token %} <input type="text" name="userMessage"> <input type="submit" value="Send to smallest_steps bot"> </form> {% endblock %} How do I create the delay between the user and bot?

When to use each model relationship in Django?
I've been reading through the Django documentation and looking over some of the other answers on the site for a couple of hours now, yet I still can't get it to sink in. I know this isn't Django specific, but the examples I use will be from a Django project. My question boils down to when is it appropriate to use each: Many-to-many relationships Many-to-one relationships One-to-one relationships One-to-one, more or less makes sense to me. Now for the other two. While I understand the differences between them in isolation, when it comes to using them practically in a project, I get confused. Here is an example: class User(AbstractUser): pass class Listing(models.Model): title = models.CharField(max_length=64) description = models.TextField() class Watchlist(models.Model): user = models.ForeignKey(User, related_name='watchlist', on_delete=models.CASCADE) item = models.ManyToManyField(Listing) class Comment(models.Model): user = models.ForeignKey(User, related_name='comments', on_delete=models.SET_NULL) comment = models.TextField() Would this be the correct use of Many-to-one(ForeignKey) and Many-to-many? Should Watchlist.item be a ForeignKey? Or is M2M correct? Wouldn't it simplify to make the 'Watchlist' part of the User class? (give them an empty list to populate with listing ID's) Why is Watchlist.user not a One-to-one relationship, if each watchlist belongs to a single user, and a user can only have … -

Django behind reverse proxy ?next= issue
I have deployed a Django application behind an nginx reverse proxy. This proxy handles multiple Django applications So the main url is for example https://www.example.com and then I use the reverse proxy to redirect to the specific Django application using subdirectory for example https://www.example.com/myapp The problem is that if I logout from myapp and try to access a page that requires login the redirect link is wrong, instead of https://www.example.com/myapp?next=/mainpage it gives me https://www.example.com/?next=/myapp/mainpage which is wrong since "myapp" cannot listen to requests from https://www.example.com/ Is there any way I can force Django to understand that the default url is https://www.example.com/myapp and not https://www.example.com?
