Django Date and time issue. Server ahead of timezone
I was working on an app and I can't solve the issue of date and time. In setting.py file I have set the timezone to UTC. TIME_ZONE = "UTC" USE_I18N = True USE_L10N = True USE_TZ = True I live in UTC+05 so when I publish a blog the date and time is 5 hours into the future so the blog can only publish after 5 hours. Is there a way to automatically detect the time zone of users to either add or subtract hours relative to UTC or anything that can automatically solve this issue. models.py class blog(models.Model): blog_text = models.CharField(max_length=1000) pub_date = models.DateTimeField("date published") def __str__(self): return self.blog_text def was_published_recently(self): now = timezone.now() return now - datetime.timedelta(days=1) <= self.pub_date <= now was_published_recently.admin_order_field = "pub_date" was_published_recently.boolean = True was_published_recently.short_description = "Published recently?" -
I want to create a set of buttons (answers to the questions) in Django, how should I do this?
I want to create a quiz site with a selection buttons, it should contain answer and two buttons with answers on em. When new user would open this quiz every button should be inactive, and once he would select one of answers then it should be active (and sent to the database), he could then return to this page and see his answers and change the answers whenever he wants. I want to do this without submit button (every answer should save after clicking). Here's my code: models.py class InterestQuestion(models.Model): q_id = models.AutoField(primary_key=True) question = models.CharField(max_length=255) answer1 = models.CharField(max_length=64) answer2 = models.CharField(max_length=64) class UserInterest(models.Model): q_id = models.ForeignKey(InterestQuestion, on_delete=models.CASCADE) user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) selectedInterest = models.CharField(max_length=64) views.py @login_required def select_interests(request): questions_data = InterestQuestion.objects.all() if request.method == 'POST': questionnaire_form = InterestSelectionForm(request.POST, request.user) if questionnaire_form.is_valid(): new_val = questionnaire_form.cleaned_data.get("userAnswer") #answered = questionnaire_form.save() #new_entry = UserInterest.objects.create(select_interests = answered) else: questionnaire_form = InterestSelectionForm() return render(request, 'quiz/quiz_form.html', locals()) quiz.html <form action="." method="post"> {% for q in questions_data %} <ul> <li>{{ q.question }}</li> </ul> {% csrf_token %} <input type="button" class="userAnswerButton" value="{{ q.answer1 }}"> <input type="button" class="userAnswerButton" value="{{ q.answer2 }}"> {% endfor %} </form> I don't know If I should use forms.py in this case, but I'll paste it … -

is it possible to build an app with scrapy without using command line interface?
I am building an app for scraping data from other sources, however, the URL would be entered by the user on a web page, and currently, I am using BeautifulSoup and Selenium to achieve the data and it is extremely slow. How this app will work? The user will visit the website, for example, example.com, and enter the URL in a form, which he/she wants to scrap. Now the problem is how I can achieve the desired result via Scrapy programmatically using Django views. Is it possible? thanks -

How to prevent Django to initialize "prod" DB before test DB
I'm using Django for the backend of my project and I'm currently writing tests. The thing is when I use the command python manage.py test, it first loads my actual DB before creating the test DB. The problem is that on DB initialization, I have some processes that do stuff with the App Registry (in my software you can install/uninstall apps while Django is running). So when I use the test command, it loads my App Registry from my local DB, then it creates the test DB but it seems to be using the same App Registry (since it uses the same settings when it starts). So I have tests that fail because things are already done in the App Registry (because of my local DB), that shouldn't be. So when I do python manage.py test, the output is : I do this : print("DB : ", connection.settings_dict['NAME']) somewhere to show you DB : my-db Creating test database for alias 'default'... System check identified no issues (0 silenced). .DB : test_my-db ..... ...tests are executed... .... Is there any setting that I could use to tell Django : "Hey, I'm using the test command, do not load my local DB … -

Django don't run the collectstatic command anymore when I upload an image from admin
I'm currently developing a Django application. I have a static-res folder that contains all my static data. In production I'm starting the generation of the "static" folder with the collectstatic command. So far everything works. From the admin part I come to import images manually with ImageField, so each time I have to run the collectstatic command... I'd like to be able to import an image in production, without having to run the command each time. Here is my code in the settings : MEDIA_ROOT = os.path.join(BASE_DIR, 'static-res/images') STATIC_ROOT = os.path.join(BASE_DIR, 'static') MEDIA_URL = 'static/images/' STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static-res'), os.path.join(BASE_DIR, 'static-res/images'), os.path.join(BASE_DIR, 'static/images'), os.path.join(BASE_DIR, 'static'), os.path.join(BASE_DIR, 'static-res/js'), ] and in my urls.py file : ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) I really can't find a solution so if anyone can help me I thank you! -
Can a Django ManyToManyField contain multiple different Model classes? How would I order it?

How can I set it up so that a List can contain both Parent and Child models? (And also have a List contain other List models for that matter?) And while I can order Child models for a Parent on the Child level (i.e. child.order), how could I order Parent, Children, and List list_items for a List? -

NGINX Docker on Server with pre-existing NGINX
I am currently running into an issue with one of my projects that will be running in Docker on my Ubuntu Server with a NGINX docker container to manage the reverse proxy for the Django Project. My issue I am running into is I already have previous Django projects running on that particular Ubuntu server so port 80 is already being used by a NGINX block running on the actual server. Is there a workaround to running my Docker NGINX as well as the Ubuntu NGINX and have my docker image run as a "add on" site because the Django sites hosted there are clients websites, so I would prefer to not interfere with them if I dont have to. My project needs HTTPS because it is serving data to a React-Native app running on Android APK 28 which for some reason has a security rule that blocks non HTTPS connections from happening in the app. If anyone else has run into an issue like this I would gladly appreciate the advice on how to tackle this issue. I have tried running NGINX in Docker with port 81 instead of port 80 and that works perfectly, but I dont think … -

are there any clever ways to save files with Web socket in Django?
I have built chatting site and I'm thinking that I can add the function of sending files besides message. But it seems that web socket can't send files or images. My solution is that when file is sent, I use api and then fetched messages and files are reordered by timestamp. But if there are better ways to achieve this, I really want to know. So, my question is Is it possible to send files by web socket and get them by WebsocketConsumer? Is there any ways to combine those two processes?

Django migrations for docker container
I have been trying to resolve an issue i am having currently, but i have not found any adequate solution neither here or elsewhere, so i was hoping someone here might have an answer. I have gotten to a point where i know what the problem is but not how to resolve it. Basically i have a website running django/postgres/nginx, it runs smoothly and i can make new models and migrate them, but if i try to add a field to the model: from django.db import models class project(models.Model): project_name = models.CharField(max_length=50) author = models.CharField(max_length=30, blank=True, null=True) date_created = models.DateField() #Added in second round of migrations #Description = models.CharField(max_length=150,blank=True, null=True) What i would normally do is initially build and spin up my container sudo docker-compose -f docker-compose.yml up --build And within my entrypoint file i run makemigrations and migrate. The first round it works well, but if i add the Description field to my model, spin down and rebuild the container to allow the new field to be included in my container, the new container is build without the initial migration, and isntead with a new migration. This results in any previous postgres tables not getting the new field added … -
How to add a field to an existing model
I would like to extend and override the fields existing in the User model, which is found in "django.contrib.auth.models" (The model is already created). I first attempted to create a Foreign-Key and a One-to-One relationship between the User model, and a Client model (in which I added the extra fields), but I don't think it is good practice. How could I directly add and override fields within the User model and not have to create another class model to extend it. from django.contrib.auth.models import User class Clients(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) #client = models.OneToOneField(User, on_delete=models.CASCADE) cell = models.PositiveIntegerField (blank=False) address = models.CharField(default = "Sandton, JHB", blank = False, max_length=132) -

Is there a way to check client in Django server without user authentication?
So I'm trying to build a Django application which provides each user with some contents but only limited to three times each day. For sake of convenience, I'm not thinking of creating/using any pre-existing user model or authentication. But since I have to limit the number of contents shown to each user, I have to tell if the current request is from the same person or not. I can think of enabling this in the front-end using local storage, cookie, etc. (Neglecting security issue or others, since this is just a toy project.) But I'm wondering if there is a way to do this in the back-end without using user authentication. Any ideas? Thank you very much in advance :) -
Static css in Django works unstable
I have css with following content in ecommerce/ecommerse/static/scc folder: body {background: #68951c;} h1 {color: #000000;} When i want to change the color of background, it changes in PyCharm, but it isn't changes on the web page even when i change a color in BOTH 1) ecommerce/static/scc and 2) ecommerce/ecommerse/static/scc manually. Even though command "python manage.py collectstatic" had run and server had re-run it is needlessly. Only one effect - when I ctrl+X following string in html page: <link rel="stylesheet" type="text/css" href="{% static 'css/base.css' %}"> then background evaporates. And when i insert the upper markup and refresh page, it appears again (upper markup contained in , in it is not working for some reason) -
