can we create arrayfield without creating model container?
I am facing problem in creating array field in mongo using django... I am using djongo connector... can't we create ArrayField in without specifying the model container ... I don't want to specify model_container in ArrayField because I don't want to make my model a child class and don't want to give value each and every field for parent class assigned in model_container... I tried - from djongo import models models.ArrayField() I am expecting - I just want to create array field in mongo db with json format/dictionary inside like [{"key1":"value1"}, {"key2":"value2"}] -
How do I make my content published automatically after a Webflow POST request
So I am adding items in my collection that I have in Webflow. The POST request I make is something like this. url = "https://api.webflow.com/collections/<collection_id>/items" payload = {"fields": {}} headers = { "accept": "application/json", "content-type": "application/json", "authorization": <bearer_token> } requests.post(url, json=payload, headers=headers) I added '?live=True' in my URL which apparently means that my content should be published without me needing to do it manually from Webflow. However, it doesn't work. Every time I create an item using a POST, I have to go to Webflow and publish my content. Is there a way around it? -

How to Django handle multiple requests send at the same time
In a web application, multiple requests can be sent to the server at the same time. Handling these requests can become a challenging task, especially if the server has to perform complex operations, like making API requests, performing database queries, etc. In this post, we will discuss how Django can handle multiple requests sent at the same time. group_name_status = {'name': '', 'status':''} def tokem_update(access_token): try: intervalInfo = UserIntervalInfo.objects.first() headers = {'Content-Type': 'application/json', 'Accept': 'application/json'} data = {'client_id': intervalInfo.client_id, 'client_secret': intervalInfo.client_secret, 'grant_type': 'password', 'username': intervalInfo.user_id, 'password': intervalInfo.user_password } response_token = requests.post(user_token, headers=headers, data=json.dumps(data)) data = response_token.text tokens = json.loads(data) access_token.access_token = tokens['access_token'] access_token.token_type = tokens['token_type'] access_token.expires_in = tokens['expires_in'] access_token.refresh_token = tokens['refresh_token'] access_token.save() return access_token except: return False def nema_status(request): if request.method == 'POST': try: group_id = request.POST.get('group_id') access_token = API_ACCESS_TOKEN.objects.first() current_datetime = timezone.now() difference = int((current_datetime - access_token.updated_at).total_seconds() / 3600) if difference > 7: access_token = tokem_update(access_token) if access_token == False: messages.error(request, "Failed update the access token" ) else: messages.success(request, 'Successfully updated the access token') headers = { "Accept": "application/json", "Content-Type": "application/json", "Authorization": f"Bearer {access_token.access_token}" } if group_id != '0': group_name = Group.objects.get(id=group_id) if group_name.object_id: par_group_nemas_status = f"https://rpt.tvilight.io/api/status?type=group&q={group_name.object_id}" response_nema_status = requests.get(par_group_nemas_status, headers=headers) if response_nema_status.status_code == 200: datas = response_nema_status.json() nemas … -
gunicorn port already in use after reboot
I'm new to stack overflow, Django, gunicorn, and so many things... so sorry in advance for any possible violation of the rules. I'm trying to make gunicorn (running on Django) service automatically restart after rebooting the server (ubuntu 18.04). When I reboot the computer, gunicorn is enabled and running, but the problem is that the port 8000 is already in use, as described in here: Django Server Error: port is already in use I can manually kill the process and restart the gunicorn (as suggested in the solution of the above link), but I want a solution to automate this process. Any suggestions would be appreciated. Thank you. I guess I need to change some config files, but not sure what to do. I didn't develop the Django web server. Somebody created for me and I'm just using it, so I have no clue how to solve this issue. -
Drill down page in Django
I'm doing my student project in Django. Now I have interesting task: drill-down page for user. He/she logs in and sees drop-list of the companies he/she has the right to view. When user chooses one of the company under that list appears another one - list of the vehicles owned by that companies. When user selects the vehicle, another list appears - list of the routes this car made so far. When user selects the car, another list appears - list of the route points, with the names of the points instead of coordinates. I tries to find out some libs or frameworks. I found out django-rest-framework-drilldown but it's fairly old enough for not to work. )) I'm kind of good with backends and apps with no graph but doing something on the front-end side almost gives me panic attack. -

Django: How to customize an add view of a model into another
I have just approached Python and Django. I am practicing with Django 4.1.7. Scenario: I have a model called Company with its name at one of its attributes. I design another model called "Company Detail" to store company information such as addresses, and phones. They are connected with the foreign key of course. Now, I write a function to create a view on the admin page for adding a new Company with its name. And I want to add the "Company Detail" on the same page. Go to the point I found a way to do that using TabularInline. However, the Company Detail's fields are many and it broke my layout. The 'country' field bleeds out of the main screen on the right, and so on with others. That's why now I want to make it display vertically. Is there any way in Django that I may archive this? -
React JS npm run build does not create index.html file correctly
Following this video guide: https://www.youtube.com/watch?v=W9BjUoot2Eo&ab_channel=DennisIvy ; however when I run npm run build after I get no compiled javascript in my index.html file; when running the server it is just a blank webpage.

Django Create Single Queryset That Counts Objects of Two Models By Month

Django user_logged_in signal not fired when used with django-allauth "remember me"
I am using django-allauth framework to authenticate user logins. I have set up a signal that is fired every time the user logs in. I am also using the "remember me" option for user logins, so that the system remembers the user and does not ask for a username and password on subsequent logins after successful authentication. What I am finding is that the signal fires when the user logs in with a username and password. However, when the user returns to the site and the login is authenticated with "Remember Me", i.e. she does not have to enter username and password; the signal is not fired. I have tried this with both django.contrib.auth.signals.user_logged_in and allauth.account.signals.user_logged_in and the result is the same. I am wondering how I can capture the user login when the user logs in with "Remember Me"? -

How can you get DurationField value in seconds in Django

Does Django open and close connection to cache every time I call cache.delete(key)?
Consider the following code snippet: from django.core.cache import cache cache.delete('key_1') cache.delete('key_2') If i'm using an Instance of Redis as my default cache, will Django create two seperate connections to the Redis instance, for each call to .delete()? or will it keep a single connection open to fulfil both calls to .delete()? I have a circumstance where I may need to delete a lot of individual keys in one go. Ideally I would like a single connection to the Redis cache to persist, rather than take on the latency of creating a new connection each time a cache method is called. Thanks -

Django - public class?
My Django project conventionally relied on functions, where many of them would retrieve the same variables/data from the database/request data. Although this works fine, it's inefficient due to the repeared code in every view function. So, I started looking at classes instead, and it seems to be the better solution for creating objects with certain reusable data. To make the data "Public", I'm storing the class object in a Public variable when returning the request data on page load, then calling that variable on subsequent calls. Although this works, it doesn't feel like a best practice. What's the best practice to make the class "Public" so that subsequent Ajax/JS calls/requests can call the same object without recreating it (unless the page changes)? Further, how could I then create multiple instances of the class in case of multiple concurrent pages calling the same view? -
How to get label of checked inupt in css
How can I change the background-color of the label from a checked radio button. Django renders form radio inputs like this: <label for="id_form-level_0"> <input type="radio" name="form-level" value="1" required="" id="id_form-level_0"> description </label> I dont have the intention to change this, so the most commun solution input[type="radio"]:checked + label { background-color: red; } does not work. In addition the :has() selector seems not to be supported in the browsers, meaning the following code neither works. label:has(input[type="radio"]:checked) { background-color: red; } What is the correct way to adress the right label in css?
