How to render multiple update forms in Django
here is my problem. I have a list of objects that I display in a table and all works just fine except that I would like to edit them inside a modal and submit them using AJAX. I though that it was a simple idea to render, for each row, a form with the inputs pre-filled and then submit the selected form with AJAX. I wonder if there is a relatively simplified way to render the UpdateForm without writing manually all the input fields. Something like this: <table> {% for transaction in transactions %} <tr> <td>{{ transaction.date|date:"d.m.Y" }}</td> <td>{{ transaction.amount }}</td> <td> <a href="#" data-bs-toggle="modal" data-bs-target="#edit{{ transaction.id }}">Edit</a> <div class="modal" id="edit{{ transaction.id }}"> {{ transaction_form }} </div> </td> <tr> {% endfor %} </table> But how can I pass the form from the view? The way I'm currently doing it is that when the user click on edit the page refresh and the modal is displayed with the form prefilled but it is (a) slow to open and (b) I don't think it is a nice way to do it. This is my current code views.py class ProjectDetailView(DetailView): model = Project template_name = "template.html" context_object_name = "project" def get_transactions(self): transactions = … -

Django error when accessing many to many through field of not managed model
I am getting this weird error which I am unable to sort out myself: 'ManyToManyField' object has no attribute '_m2m_reverse_name_cache' Relevant parts of code are these: models.py: class Section(models.Model): type = models.IntegerField(blank=True, null=True) child=models.ManyToManyField( 'self', through='SectionParent', through_fields = ('parent_section_id', 'section_id'), ) class Meta: managed = False db_table = 'section' class SectionParent(models.Model): section = models.ForeignKey(Section, on_delete=models.CASCADE, related_name="m2m_child") parent_section = models.ForeignKey(Section, on_delete=models.CASCADE, related_name="m2m_parent") class Meta: managed = False db_table = 'section_parent' views.py: def navigation(request, section_id=None): # Load species if no id is provided if not section_id: sections = Section.objects.using('app-db').filter(type=SectionType.speciesCategory.value[0]).first() # Load children of current section else: sections = Section.objects.using('app-db').filter(id = section_id).first() print(sections.child()) <-------------- ERROR HERE return HttpResponse("test") I tried to modify models.py many times including adding related_name, replacing 'self' with 'Section' and other things, changing name of the relationship (child), but nothing seems to sort this out. I think it might be related to the fact that the model runs over existing database (hence managed = false), as I never got such an error with migrations enabled. -

Connection refused setting up Nginx + Gunicorn/Django REST
I have a setup with Nginx as web server, Gunicorn as application server serving a Django REST API, all of this inside a docker container. Within the container, I launch gunicorn using this command: gunicorn --bind 0.0.0.0:8000 cdm_api.wsgi -t 200 --workers=3 and I am able to access to the API running for instance: curl -d "username=<user>&password=<pass>" -X POST http://127.0.0.1:8000/api/concept However, when I run the same from outside the container I get: curl: (7) Failed to connect to 127.0.0.1 port 8000: Connection refused Nginx is listening to port 80 inside the container which maps to port 8080 outside the container in localhost. I am able to access nginx but it seems nginx is unable to act as reverse proxy and redirect calls to 8000 (outside the container) to 8080 (inside the container). Here is my nginx conf file: server { listen 80; listen [::]:80; server_name 127.0.0.1; location /api/ { proxy_pass http://127.0.0.1:8000; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Real-IP $remote_addr; proxy_connect_timeout 360s; proxy_read_timeout 360s; } location / { root /usr/share/nginx/html; index index.html index.htm; } } Let me know if more information is needed.

No such file or directory: 'profile_pics/img.jpg'
When a user attempts to upload a profile picture this error is displayed. However the image is successfully uploaded to the database and displayed in the app. I believe the error is something to do with the redirection after the form submits but I couldn't figure it out.

The error message is : MultiValueDictKeyError at /prediction/ 'date1' Request Method: GET Why is the request Method still GET even though I have POST in my views.py? Views.py : from django.shortcuts import render from apple.models import predictions # Create your views here. def home_view(request): pre = predictions.objects.filter(date='2021-01-15') return render(request, 'homepage.html', {'prediction': pre}) def read(request): final_date = str(request.POST["date1"]) price = predictions.objects.filter(date=final_date) return render(request, 'results.html', {'price':price}) This is my 2nd HTML page Results.html : <!DOCTYPE html> <html> <head> <link href='https://fonts.googleapis.com/css?family=Pacifico' rel='stylesheet' type='text/css'> <link href='https://fonts.googleapis.com/css?family=Arimo' rel='stylesheet' type='text/css'> <link href='https://fonts.googleapis.com/css?family=Hind:300' rel='stylesheet' type='text/css'> <link href='https://fonts.googleapis.com/css?family=Open+Sans+Condensed:300' rel='stylesheet' type='text/css'> <title>Prediction Page</title> </head> <body> <h1>"The Predicted price for this date is:" + "{{price}}"</h1> </body> </html> <style> @import url(https://fonts.googleapis.com/css?family=Open+Sans); html { width: 100%; height: 100%; overflow: hidden; } body { width: 100%; height: 100%; font-family: 'Open Sans', sans-serif; background: #331952; color: #fff; font-size: 18px; text-align: center; letter-spacing: 1.2px; } </style> This is the main HTML Page - homepage.html ( from where 'date1' is coming from ) : <!DOCTYPE html> <html> <head> <link href='https://fonts.googleapis.com/css?family=Pacifico' rel='stylesheet' type='text/css'> <link href='https://fonts.googleapis.com/css?family=Arimo' rel='stylesheet' type='text/css'> <link href='https://fonts.googleapis.com/css?family=Hind:300' rel='stylesheet' type='text/css'> <link href='https://fonts.googleapis.com/css?family=Open+Sans+Condensed:300' rel='stylesheet' type='text/css'> <title>Apple Stock … -
Tried to update field with a model instance, <SimpleLazyObject:<<>>. Use a value compatible with CharField
I am trying to over ride the save method in my model to store the currently loged in user. I am using the django-current user to get the authenticated user. I wrote this code from django_currentuser.middleware import ( get_current_user, get_current_authenticated_user) from django_currentuser.db.models import CurrentUserField uploaded_by = models.CharField(max_length=255, blank=True, null=True, editable=False) def save(self, *args, **kwargs): user = get_current_authenticated_user() self.uploaded_by = user super(Citation, self).save(*args, **kwargs) But I am getting this error Tried to update field professional.Citation.uploaded_by with a model instance, <SimpleLazyObject: <CustomUser: staff@gmail.com>>. Use a value compatible with CharField. Please suggest me what should I do as I want to store the currently loged in user in the model save method and aslo keep this field non editable.
