Overrinding a field in different table on django

Can i have multiple views and serializers for single model in django rest framework
I am building an application in which an owner is posting a job post and multiple user will apply for that job application. I have provided an endpoint to user to apply for a certain job post and it went successful. Then, I tried to provide a separate endpoint to an owner in which I want to view the application and edit the status of the application. To implement this I used a separate serializer which allows only status field to be updated and making rest of the fields as read only. Additionally, I created the separate view as well for the owner to update the status of the application based on id filter. Lastly, creating a separate URL as well. So, the 2 URLs are: /api/job/application (for user) /api/job/application-status (for owner) But I ended up in a situation where I am getting the same URL for both of the job application endpoint and job application status endpoint because they are using same model. So, is it possible to have multiple views and serializers for a single model? If Yes, then how can I achieve this and what permissions should I use for owner. -

Django, MVC pitfalls for POSTs when rev proxy down, caching failed POSTs, none user Auth
Disclaimer Firstly, I understand SO is for code based answers, I did some research on where to ask this questions, and it seems like according to the community SO got 20 votes for asking: Questions about deployment and support of applications past release, in particular towards design for maintainability. Intro My question is I personally spent last 2 years working on a Django project for a factory, it uses the standard MVC pattern. The app uses the factory IP for authentication for terminals in the factory. It was my first web project and I have learnt a lot from it, and hence re-written many aspects of it. 3 Problems with Django MVC However I have now reached a point where I am wondering if it needs a re-write since I see no great solutions to the following problems with the MVC pattern: I wish to be able to POST data, and control what happens if it fails on the client side. With a normal POST, once one has submitted the form, one let's go of control. This means if the server is restarting, or receiving an update, and the reverse proxy (UWSGI) is not up yet, Nginx shows an error … -

Django. How do I add a field to a query result?
I have a Room model and I want to add the is_member boolean field to a queryset with rooms. How can do this? I was thinking of using .annotate (), but that doesn't work for my task. models.py from django.db import models class Room(models.Model): name = models.CharField(max_length=150) members = models.ManyToManyField(User, blank=True) views.py from rest_framework.views import APIView from rest_framework.response import Response from .serializers import RoomSerializer from .models import Room class RoomView(APIView): def get(self, request): rooms = Room.objects.all() # get all rooms user = request.user # get current user for room in rooms: members = room.members.all() # get members is_member = user in members # set boolean value room.is_member = is_member # set in room serializer = RoomSerializer(rooms, many=True) return Response(serializer.data) serializers.py from rest_framework import serializers from .models import Room class RoomSerializer(serializers.ModelSerializer) is_member = serializers.BooleanField(read_only=True) class Meta: model = Room fields = "__all__" I solved this issue this way, but is there any other options to do it?

Django | REST | Three related tables to JSON

What I am able to do, is get model_set from a Make and Type, but is there any way, how to combine these? Or this DB model is bad? I have added ForeignKey of Type to Model table, because for example Honda can produce Automobiles and also Motorcycles - just name of its vehicle model will be different. Another option here, is to use two serializers - for Make and Type with Filtering in Rest framework via django-filter, but when I created solution, which should work, I am able … -
Django application mod_wsgi error with apache
I'm hosting Django app on AWS ec2 with ubuntu 20.04 lts. I can run the app with venv on various ports.

I want to fetch the data from a table which is in database and then display it in tabular format in my webpage. Only the html column name is being shown but not the data from the database table. Can anyone please help me out with this? My codes: views.py: def display_majorheads(request): outputs = ProcessedOutputs.objects.all() be_year = 0 context = { 'processed_outputs':outputs, 'be_year':be_year, } return render(request, 'website/mhead.html', context ) mhead.html: <table class="table table-striped"> <tr> <th>MajorHead</th> <th>BeSalary</th> <th>BeGiaSalary</th> <th>BeOther</th> <th>BeTotal</th> <th>BeNextyrSalary</th> <th>BeNextyrGiaSalary</th> <th>BeNextyrOthrs</th> <th>BeNextyrTotal</th> </tr> {% for processed_outputs in outputs %} <tr> <td>{{ processed_outputs.major_cd }}</td> <td>{{ processed_outputs.be_salary }}</td> <td>{{ processed_outputs.be_gia_salary }}</td> <td>{{ processed_outputs.be_other }}</td> <td>{{ processed_outputs.be_total }}</td> <td>{{ processed_outputs.be_nextyr_salary }}</td> <td>{{ processed_outputs.be_nextyr_gia_salary }}</td> <td>{{ processed_outputs.be_nextyr_others }}</td> <td>{{ processed_outputs.be_nextyr_total }}</td> </tr> {% endfor %} </table> -
Django migrate/makemigrations does not work when postgres server is running
When the server is up and I give python manage.py makemigrations, it does nothing. It looks like it is waiting for something indefinitely. When I shutdown my pgAdmin4 server, it works fine. What could be the problem here? -

Django - Pass a dictionary to template through the get_queryset function of a class based view
Is there a way to return a dictionary through the get_queryset function of a class based view in Django? I want to pass the array tickets and the string email to my template, but I am only able to pass tickets right now. Content of views.py: class UserTicketListView(ListView): model = Ticket template_name = 'ticket_system/user_tickets.html' context_object_name = 'tickets' ordering = ['-date_posted'] paginate_by = 5 def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get('username')) email = User.objects.get(username=user).email return Ticket.objects.filter(author=user).order_by('-date_posted') -
Outputting two colums of dataframe into Django template using For Loop
I am trying to parse 2 columns of my dataframe(my_tweet_df) from views to Django. The dataframe is off Tweets data which I fetched from Tweepy. I hope for my output to look like this: USERNAME TWEET username1 tweet of username1 username2 tweet of username2 ..... ..... In my HTML page, code looks like this: <table class="table table-hover"> <tr> <th><h4>Username</h4></th> <th><h4>Tweet</h4></th> </tr> {% for key in my_tweet_df %} <tr> <td>{{key.author}}</td> <td>{{key.text}}</td> </tr> {% endfor %} </table> I do not know how to do so using for loop. I have tried passing dataframe: {% for key in dataframe %} with {{key.user}} and {{key.text}}. I know this approach is not correctenter code here as it is looping through range of dataframe not values of one column. I have tried converting to single columns and back to dataframe and passing like: my_tweet_df = pd.DataFrame(list(zip(my_tweet_df.user, my_tweet_df.text)), columns=['username', 'status']) But that again doesn't work because it is a 2D arary now and has a range of 2 only. Even if I try to pass them separately, I don't know how to do so using 2 for loops, like: {% for key in text %} <tr> <td>{{key}}</td> <td>{{key}}</td> </tr> {% endfor %} But in the above approach …
