Changing the date format from JSON data
I'm currently trying to teach myself Django and I'm a little confused on how to modify data from a web API. For example I request an api with a url: api.example.com/events?location=.... And I get JSON data {'data': [ { 'name': 'blah' 'date': '2019-03-22' }, { 'name': 'blah2' 'date': '2019-03-23' }, ] } The date is outputted as "yyyy-mm-dd" and I want to change it to "mm dd yyyy". Would I have to put the JSON data into a model? If so, how would I go about doing so? -
How do I return a class-based view method with super from a function within that very same class-based view method?
Is it even possible? I can't find anything or figure it out by myself since I'm a beginner, so I turn to you guys. Here's an example (don't worry about the use case, I just want to know if it's possible and how): When I run this code I get that *args is not defined. What's wrong? views.py: class MyCreateView(CreateView): def get(self, request, *args, **kwargs): slug = kwargs['slug'] helper_method(self, slug) helpers.py: def helper_method(self, slug): if slug == "random": return super(self.__class__, self).get(request, *args, **kwargs) -
Python Django working with multiple database simultaneously
I'm still a noon Django developer.kindly excuse the silly. I've been trying to add in a functionality to my already existing Django application. Currently my application only services multiple users belonging to an organization. I'm trying to accomplish a task where in: 1. Multiple organizations can work with my application by having separate database. This way organization specific data is private to individual organization. 2. For every organization that wants to subscribe to the web app services, the web app shall use a database template to create the database for. The new organization and commission it. 3. The web app should handle/service all organizations simultaneously. Is this possible? I have tried performing multiple research. Unfortunately, I have not gotten any substantial breakthrough. Any kind of help is much appreciated. Cheers! -
Use django-filters on multiple models
I'm trying to create a search capability in my Django project that will filter multiple models (currently 3). It worked great for one model, worked when I added a second, but when I tried to add a dropdown menu for the third model, I got an error saying they keyword was unavailable (because it wasn't looking in the model): Cannot resolve keyword 'rooms' into field.

How to render json to html?
I've JSON file: [ { "key1": "value1", "key2": "value2" }, { "key3": "value3", "key4": "value4" }] Output should be: <h1>value1</h1><p>value2</p><h1>value3</h1><p>value4</p> I'm trying like that: import json with open('file.json') as f: data = json.load(f) for key in data: for k, v in key.items(): print(k.replace(k, '<h1>') + v + (k.replace(k, '</h1>'))) But it's horrible and stupid :( Also, I have another JSON file: [ { "h1": "value1", "div": "value2" } ] Output should be: <h1>value1</h1><div>value2</div> My solution: with open('file2.json') as f: data = json.load(f) for key in data: for k, v in key.items(): print(f"<{k}>" + v + f"</{k}>") This one is work, it's possible to make it better? And the last one: If JSON have a list, each element it's has should be <ul> tag, and each <ul> element should contain <li> element: JSON: [ { "h1": "value1", "div": "value2" }, { "h1": "value3", "div": "value4" }] Output should be: <ul><li><h1>value1</h1><div>value2</div></li><li><h1>value1</h1><div>value2</div></li></ul> How can i solve these task? Please give me some advice which way i can dig it. With Python or Django -
How do I save records to the right schema/tenant?
I'm working on a multi-tenant application in Django, using django-tenant-schemas. However, when I save users, they don't seem to be properly attached to their tenants. When I query the list of users on a tenant I get a list of all the users in the database. I can see that the records have the right foreign keys but they all appear to have been lumped together in the same schema. I looked through this Multi-tenant schema with django and this User doesn't exists and no redirect to created tenant in django project, but I can't get mine to work properly Here's my tenant model(estates/models.py): from django.db import models from tenant_schemas.models import TenantMixin from .managers import EstateManager # Create your models here. class Estate(TenantMixin): name = models.CharField(max_length=100, unique=True) slug = models.CharField(max_length=20, unique=True) is_active = models.BooleanField(default=True) created_on = models.DateField(auto_now_add=True) auto_create_schema = True objects = models.Manager() tenancy = EstateManager() Here's my custom user model (authentication/models.py): from django.core.mail import send_mail from django.contrib.auth.models import PermissionsMixin from django.contrib.auth.base_user import AbstractBaseUser from estates.models import Estate from .managers import UserManager class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField('email address', unique=True) phone = models.CharField('phone', max_length=50) first_name = models.CharField('first name', max_length=100) last_name = models.CharField('last name', max_length=100) created_at = models.DateTimeField('date created', auto_now_add=True) is_active … -

Dispatching requests from one uwsgi to another uwsgi instance running Django Channels
I am currently using Django channels for websocket communication. I read this article and it states that I should split the project into two uwsgi instances. It states that "The web server undertakes the task of dispatching normal requests to one uWSGI instance and WebSocket requests to another one" Now I have two uwsgi instances running. This is how I am running both. This uwsgi handles the normal django site requests uwsgi --virtualenv /home/ec2-user/MyProjVenv --socket /home/ec2-user/MyProjVenv/MyProjWeb/site1.socket --chmod-socket=777 --buffer-size=32768 --workers=5 --master --module main.wsgi This uwsgi handles the websocket requests uwsgi --virtualenv /home/ec2-user/MyProjVenv --http-socket /home/ec2-user/MyProjVenv/MyProjWeb/web.socket --gevent 1000 --http-websockets --workers=2 --master --chmod-socket=777 --module main.wsgi_websocket Now the websocket uwsgi launches main.wsgi_websocket The code for main.wsgi_websocket one is this import os import gevent.socket import redis.connection redis.connection.socket = gevent.socket os.environ.update(DJANGO_SETTINGS_MODULE='main.settings') from ws4redis.uwsgi_runserver import uWSGIWebsocketServer application = uWSGIWebsocketServer() Now after spinning up the two uwsgi instances I am able to access the website fine.The websocket uwsgi instance is also receiving data however I am not sure if its passing that data to the django website uwsgi instance which basically uses django channels. I am using Django Channels here and this is the configuration I have specified in my settings for Django Channels CHANNEL_LAYERS = { "default": { … -
Am I legally allowed to use the backend from this place that shut down a while ago, and their code got out to people for them to download
So there is this company that shut down, and they released their source code on the website some people downloaded it and now sell it I managed to get my hands on it. I was wondering if I am legally allowed to use the website and the backend they made. Like will I have to get permission from the owner (if so going to be hard as the owner scammed thousands of dollars from people). So I just want to be in the clear if I can use it or not. Also I 100% have the rights to use the front end as the front end developer released it as open source. -

Django Allauth signup form POSTs but no redirect, no email sent
This was all working fine for weeks, I haven't changed anything except taken a few fields off of the signup form (password which I've tried putting back and still same problem). I'm using Allauth with Django and the generic signup form /accounts/signup/ isn't redirecting to verification_sent.html. An email_confirm.html is also not being sent to confirm the account. I've set up an email backend to test on localhost and normally the emails come through fine via the terminal window. Now when I submit the form and request.POST, nothing happens. No emails, no verification_sent.html page redirection. The terminal isn't throwing any errors and says HTTP POST /accounts/signup/ 200 How can I go about debugging this? signup.html <form method="POST"> {% csrf_token %} {{ form.email|as_crispy_field }} {{ form.first_name|as_crispy_field }} {{ form.last_name|as_crispy_field }} <button type="submit" value="submit" id='signup_button'>Sign Up</button> </form> forms.py # User signup form class UserRegisterForm(forms.Form): email = forms.EmailField() first_name = forms.CharField(required=True) last_name = forms.CharField(required=True) def signup(self, request, user): user.first_name = self.cleaned_data['first_name'] user.last_name = self.cleaned_data['last_name'] user.save() settings.py ACCOUNT_SIGNUP_FORM_CLASS = 'users.forms.UserRegisterForm' ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_UNIQUE_EMAIL = True ACCOUNT_EMAIL_VERIFICATION = 'mandatory' ACCOUNT_USERNAME_REQUIRED = False ACCOUNT_AUTHENTICATION_METHOD = 'email' ACCOUNT_EMAIL_CONFIRMATION_EXPIRE_DAYS=7 ACCOUNT_LOGIN_ATTEMPTS_LIMIT = 5 ACCOUNT_LOGIN_ATTEMPTS_TIMEOUT = 86400 # 1 day in seconds -
React in Django or React as a standalone?
I have been researching how to create django react application and the best way to go about implementing it. From this link on creating a django react app states a few way to go about implementing it. One way is to generate a webpack and using django to load the webpack another is to run it as 2 separate applications. What are the obvious benefits of "React in its own “frontend” Django app: load a single HTML template and let React manage the frontend" vs "Django REST as a standalone API + React as a standalone SPA" Because I do not see a need of generating a webpack and loading the application in django template where you could create a standalone react app and use Django REST for communication? -
How to save new Django database entries to JSON?
The git repo for my Django app includes several .tsv files which contain the initial entries to populate my app's database. During app setup, these items are imported into the app's SQLite database. The SQLite database is not stored in the app's git repo. During normal app usage, I plan to add more items to the database by using the admin panel. However I also want to get these entries saved as fixtures in the app repo. I was thinking that a JSON file might be ideal for this purpose, since it is text-based and so will work with the git version control. These files would then become more fixtures for the app, which would be imported upon initial configuration. How can I configure my app so that any time I add new entries to the Admin panel, a copy of that entry is saved in a JSON file as well? I know that you can use the manage.py dumpdata command to dump the entire database to JSON, but I do not want the entire database, I just want JSON for new entries of specific database tables/models. I was thinking that I could try to hack the save method on … -
API not sending email
I am trying to build a rest API that will ask for an email, subject and message from the user and send that subject and message to the email provided in the email field, from the email registered in the settings.py file.

I am newbie in django rest framework if someone could tell me exact what I am doing wrong in this will be quite helpful. -

How to handle an image upload before creating the entry for the account in the database?
I'm building a single page application. On the client side I'm using Nuxt.js (which includes Vue.js and Vuex). To send and receive data to the server I use axios. The API was built with the Django REST framework. I have the following scenario: If a user wants to register, he starts on Page 1. Here he has the possibility to upload a profile picture. As soon as he has selected the picture it will be uploaded automatically into an S3 bucket. During or after the upload he can fill in the other fields First Name and Last Name. All these fields are temporarily saved in the Vuex store which means if the user reload the page the data is gone. If he clicks on Next Page he will be taken to another page (another URL; no page reload -> Single Page Application) where he can enter the remaining data. After clicking on the button Create Account the entry is created in the database. Now to my question... How should I handle the image upload? As already said, the picture should be uploaded directly after the selection and not only when you click on the button Create Account. At some point …
