How to extract data from the Database based on the input fields given in the HTML form using Django

Empty QuerySet for Django Multi-Table Inheritance Subclass
I have the following models: APP 1: class User(AbstractBaseUser): # custom fields etc # NOT ABSTRACT APP 2: class SecondaryUser(User): # other custom fields When I do SecondaryUser.objects.create(...) I get an instance as expected: In: SecondaryUser.objects.create(first_name='test', last_name='test', email='test@etest.com') Out: <SecondaryUser> This has an id and populated fields as expected. I can also query the base class and use the django-generated 1-1 field for the inheritance to access the subclass's fields: User.objects.get(email='test@etest.com').secondaryuser.<some_field> However when I do SecondaryUser.objects.all() it returns an empty queryset. And the model admin for the SecondaryUser shows an empty list view (even when I create a new instance of SecondaryUser in the admin create view). I feel like I'm missing something obvious, I need to be able to list the SecondaryUser instances in the admin. The User class cannot be abstract. -

Django & Celery - Domotic Project with Raspberry

The script runs well stand alone but I need to integrate it into a django app to control certain cases (e.g. temperatures, humidity, manual switches, etc.) So, I have pip installed celery and redis and configured it. What I need to understand is how to make the while scrip start contextually to the app and not block it when the app starts. The script is very simple def startdomo() stuffs = Stuffs.objects.get(pk=1) while True: do some stuffs I try to put it into url.py at the end urlpatterns = [ url(r'', include('FBIsystem.urls')), ] startdomo() In this case startdomo run but django app not run.

Django - is token/JWT authentication safer if backend and frontend are on the same server?
I'm researching the best security approaches for a webapp that i want to build, where the backend should be separated from the frontend but they will both be on the same server. The frontend is a standalone VueJS application while the backend is a Django app that will communicate with Vue using JSON, but i think this still applies to other frameworks like react or angular. For authentication, i would use djoser and probably token based authentication or JWT. I made some research about this topic and found that there are some concerns on token based authentication, mostly related to token storage on the client side. My question is: when backend and frontend are on the same server, instead of being cross domain, do these security concerns still apply? Or is it a much safer approach? If i deploy the two apps on the same server, can i store the tokens on Vuex or any other local storage safely? What can i do, instead, on the Django side, to make the app as safe as possible? -
Calling two fetch Requests in Django with Javascript displays the result in the same div
I am really new to Javascript therefore be kind! There must be something wrong with the way I am structuring this. I have seen possible solutions, could involve async functions and I tried them but for some reason, I might not get the order straight, or simply I am missing the point. I am using a fetch request to source some data at first from the API that I made on my local server. And that works fine. I am able to source the names of the cryptocurrencies that I have coupled with a username in JSON format. After I have created the styling for the divs to display and inserted the data in, I call another fetch for another API this time external, to further source data and insert it in divs I have created previously, per each piece of data I sourced from my own API. For some reason, it ends up displaying the data that I am fetching from this external API all in the same div, instead of displaying them for each. I have tried a forEach function, I have tried (i=0;i<data.lenght;i++), I have tried to place it differently, I have tried creating global variables and … -
making context variable from one method accessible to other other methods (and views) in Django
i'm working on a dashboard project (django + charts.js) that currently looks like this: currently, all of the charts are based on all the data in the database (approx 1.5 mil lines). however, i'd like these charts to be responsive to the dates indicated in the start date/end date HTML widget - e.g. show payment methods, taxi orders by the hour/day of week according to the start/end dates indicated. my date_input method gets the start and end dates from the frontend, and queries my MySQL database according to the dates selected. these queries are then rendered to the context variable of date_input - however, i'd like the context variable in date_input to be available to all methods (each chart is rendered by a different method, based on the JsonResponse returned to different endpoints). i've tried making context available as a global variable by defining it outside date_input as queryset = date_input(request) - NameError: name 'request' is not defined. i've looked into context processors, but that seems to be an option only if i didn't have a request (e.g. start/end date input from the frontend). i'm rather confused and would appreciate some help. here's my views.py code: def date_input(request): if request.method … -
Set different password for Django admin users than for the public Django app
We have a Django app where we're using the default password/password reset functionality. Lots of our staff also login to Django admin using the same credentials. Is it possible to create separate passwords for these two areas (the public app and Django admin)? The advantage of doing this is I can set & enforce strong passwords for everyone in Django admin, and people aren't tempted to change them to something that's easier to log into the public app with. -
Django - Override save() method of auth_user model
I want store the username of the auth_user table into the first_name, if no first name is provided. Something like this: from django.contrib.auth.models import User class CustomUser(User): class Meta: proxy = True def save(self, *args, **kwargs): if not self.first_name: self.first_name = self.username super(CustomUser, self).save(*args, **kwargs) Thank you
