Using file.js in the script of an external html document, which is not on the server
I would like to use a file.js document from my Django-Server as a script of an external html-document, which does not belong to my server. That´s why I tried to implement the file.js as an path and use the link of this path for my html document as a script, but it did not work because the script could not be gotten from the html document. Does anyone has an advice for me what I did wrong? file.js: var test = {“variable“:“test“} test.html: <script href=“https://url_of_my_server/file.js“> </script> -
Celery task (.delay()) causes Django to freeze if I'm using Gunicorn or uWsgi
If I'm using celery with Django (by calling .delay()) while using Gunicorn or uWsgi it causes it to freeze and eventually timeout. I'm guessing it gets stuck trying to send task to broker. This is happening on both developer server and production server, where both are running Ubuntu 20.04. Using built in developer server using python3 manage.py runserver works without any issues. And removing the .delay() also makes it work automatically. Example task: @shared_task def SayHello(): print('Hello!') Celery config in settings.py: CELERY_BROKER_URL = 'redis://:password@ip:6379' CELERY_RESULT_BACKEND = 'redis://:password@ip:6379' CELERY_ACCEPT_CONTENt = ['application/json'] CELERY_RESULT_SERIALIZER = 'json' CELERY_TASK_SERIALIZER ='json' init.py: from __future__ import absolute_import, unicode_literals # This will make sure the app is always imported when # Django starts so that shared_task will use this app. from .celery import app as celery_app __all__ = ('celery_app',) celery.py (in project folder with settings.py): import os from celery import Celery # Set the default Django settings module for the 'celery' program. os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'djangoProject.settings') app = Celery('djangoProject') # Using a string here means the worker doesn't have to serialize # the configuration object to child processes. # - namespace='CELERY' means all celery-related configuration keys # should have a `CELERY_` prefix. app.config_from_object('django.conf:settings', namespace='CELERY') # Load task modules from all … -

how to complete some part of form in another page?
I made a contact form for the users to complete in their profile. It consists of some simple fields like address and phone number and a location field to choose their coordination on a map. However, I want the location field on another page. for instance, when a user wants to fill this form, they first fill in other fields, then by clicking a button they get redirected to another page to fill the location field and then again return to the form and submit everything. is this even possible? how can I submit part of a form on a page and the rest on another page? -
How are applications (which accepts different types of requests like http and smtp) deployed on different ports on servers?
I'm a beginner in all these http and tcp/ip thing. So there maybe many things in these questions that may not make sense or are totally incorrect. First I will add all the questions I had in mind since, I could not put them on title. I work on django (python framework) for web development. I'm confused as to how servers work. And how is the destination port is decided through the url? MAIN Q : What I have learned so far is that through DNS we get the ip address of the website. And port (Both destination and source) are decided by the TCP. And sent through TCP headers. But how does it decide which port should it go to in a server(i.e. destination port). MY ANS TO ABOVE QUESTION : After spending lots of my time, I have come to know that, http requests default to 80 and https defaults to 443 and similarly other types of requests also defaults to some port. So we can figure out the ip address based on this. But this rises another question in my mind. Another Question : I have also built a simple django website and deployed it on pythonanywhere. … -

How do I refresh my JWT provided by Django-Rest-Framework, using Apisauce from my React-Native App?
I am building an Application with Django-Rest-Framework backend and using dj-rest-auth for authentication with Simple JWT and for the frontend I am using React-Native and am making my api calls using api-sauce (github link -> API-Sauce). API-Sauce is built on axios This is my basic clientAPI code which hits the Django-Rest-Framework from my React-Native app import { create } from "apisauce"; import authStorage from "../auth/authStorage"; const baseURL = "http://192.168.0.109:8000/api"; const apiClient = create({ baseURL: baseURL, }); apiClient.addAsyncRequestTransform(async (request) => { const authToken = await authStorage.getToken(); if (!authToken) return; request.headers["Authorization"] = "Bearer " + JSON.parse(authToken).access_token; }); export default apiClient; This works perfectly as long as the Token is active. Once the token has expired, to refresh my token I have to do the following Target URL - http://192.168.0.109:8000/api/token/refresh/ Header - "Content-Type" : "application/json" data - {"refresh":"refresh_token"} // refresh_token is obtained from authStorage in the above code-snippet like so //JSON.parse(authToken).refresh_token How can I efficiently add the code which refreshes my token, to my existing code, which makes my API to call refreshes the token automatically? -
Django: Passing variable from view to view via url link
I am learning Django and as part of a project, am trying to reference a topic from view1 called "page" (containing content) to be passed into view2 called "editpage" (where I can edit the respective topic). I believe one way to do this is via sessions, but given I only need to reference the topic a single time when the user wants to edit view1 - is there a way to pass the topic from view1 to view2 without sessions and forget the topic once the edit has been made? From the best answer to the question below, it seems I can do it via redirects? But I cannot find a way to use redirects with url links. Django Passing data between views My attempted approach was to have the editpage url contain the topic from view1, but I do not know how to pass the topic between the two views. Attempted code below for page and editpage in urls.py, views.py, page.html and editpage.html: urls.py from django.urls import path from . import views urlpatterns = [ path("editpage/<str:topic>", views.editpage, name="editpage"), path("<str:topic>", views.page, name="page"), ] views.py from django.shortcuts import render from django.http import HttpResponse, HttpResponseRedirect from django.urls import reverse from django import … -

Django: OR filter on Q object and manytomany values is slow
By doing the following, you can get an object whose title and tag name contain value. However, Q object and .distinct(), the query execution time will be very slow. Model.objects.filter(Q(title__icontains=value) | Q(tags__name__icontains=value)).distinct() In this case, do you recommend creating a field called search in the model and storing the values of title and tags__name in it, separated by spaces? tags = list(Model.tags.values_list('name', flat=True)) Model.search = f"{Model.title} {' '.join(tags)}" Model.save() -

It's possible to have relationships between models stored in different databases in Django?
I'm currently working on a project where I handle both public and private information, both stored as different models in a common database. I would like to split this database in two, one with the private model objects and another one with the public ones. The thing is, both this models have a ForeignKey relationship with each other, and I've found conflicting answers over the internet about if this relationships can work even if the models are in two different databases. So, is this possible? Is there a better approach for doing this? Just to clarify why I want to do this, I want the project to be open source, therefore the public database should be public, but the sensitive information (users and passwords) should be kept private. -

If it's right, what should I be passing as parameters to the get() method? *P.s. I'm not using DRF for this approach and I'm building the app where Django and React is in one app (not separate) where the frontend is an app of Django. -

Another "fk_name ' ' not a foreignkey to" problem [Python/Django]
please don't judge with my question. I tried every suggestion here but still no luck. here's my code --- admin.py from django.contrib import admin from .models import candidates_info, address class addressInline(admin.TabularInline): model = address fk_name = 'id' @admin.register(candidates_info) class candidates_infoAdmin(admin.ModelAdmin): fields =['last_name', 'first_name', 'middle_name', 'moniker'] inlines = [addressInline] models.py import datetime from django.db import models from django.utils import timezone class candidates_info (models.Model): last_name = models.CharField(max_length=50) first_name = models.CharField(max_length=50) middle_name = models.CharField(max_length=50) #position = models.ForeignKey('positions', db_column='position_id', on_delete=models.CASCADE, null=False) #birth_date = models.ForeignKey('birthdate', db_column='date_of_birth_id', on_delete=models.CASCADE, null=False) #contact_info = models.ForeignKey('contact_info', db_column='contact_info_id', on_delete=models.CASCADE) addr = models.ForeignKey('address', on_delete=models.SET_NULL, null=True) moniker = models.CharField(max_length=35) #party = models.ForeignKey('political_parties', db_column='political_parties_id', on_delete=models.CASCADE, null=False) registration_dt = models.DateTimeField('date registered') class address(models.Model): lot_no = models.DecimalField(max_digits=5, decimal_places=0) block_no = models.DecimalField(max_digits=5, decimal_places=0) note: the codes commented out (#) are part of my code in models.py which I temporarily disabled as part of my code to see if it's conflicting with the declaration of foreignKey. and another thing, tried declaring and undeclaring fk_name on admin.py but still no luck. Please help guys. Been stock here for a few days now. I can't seem to find the bug. TIA btw.. here's the error from console --- <class 'votenow.admin.addressInline'>: (admin.E202) fk_name 'id' is not a ForeignKey to 'votenow.candidates_info'.
