Django Failed to load css
I have installed Geonode ( geospatial content management system), which is available on URL armsis.cas.am. It worked fine, but now there is a problem with CSS. I get an error GET http://armsis.cas.am/static/geonode/css/base.css net::ERR_ABORTED 403 (Forbidden) I thought the problem was in the path to static folder, but I get images from the same folder. Any ideas? ('m not a programmer, but I have some skills in Python/Web) -
Django verbose_name of reverse relation
I have a model like: class Question(models.Model): ... class Answer(models.Model): question = models.ForeignKey( Question, null=False, blank=False, on_delete=models.CASCADE, related_name='answers', verbose_name='translated name' ) I would now like to use the verbose_name in a template (as it is translated) over the reverse relation like {{ question.answers.verbose_name }}. Unfortunately this does not work. On the other hand {{ question.answers.related_name }} works. So it seems that in the reverse_relation only the related_name is available. Is there any way to get the verbose_name from the reverse relation? -

Different CMDs - difference for Python
I am a Windows10 user learning Django. And I am trying to run a server on my local device. While using the PyCharm command prompt, I constanly got some errors. A previous one, for example, was caused by SSLError (error was fixed thanks to Stackoverflow answers). Currently while doing the "runserver" command I am getting a new error: ImportError: DLL load failed while importing _sqlite3: module not found. At the same time there were and there still are absolutely no errors shown while using same django commands, but in Anaconda prompt. Why is that so? What's the difference between prompts? How to make the PyCharm command prompt work normally? "Anaconda3", "Anaconda3\scripts" and "Anaconda3\Library\bin" have been added to my PATH already. (According to answers found among Stakoveerflow, adding them is the number one solution / advice). Thank you! -

Django ORM update field to NOW() returning 0 error
I am trying to loop through a list of results, process them, then update their "updated_details" field. users_to_update = TiktokUser.objects.filter(Q(updated_details__lt=datetime.utcnow() - timedelta(weeks=1)) | Q(updated_details__isnull=True))[0:1] for user_to_update in users_to_update: print(datetime.now()) user_to_update.updated_details = datetime.now() user_to_update.save() The idea being that on each loop, i set the updated_details to the current timestamp. My print() statement here correctly prints out the current date and time, however when I update the record itself and save, I get the following error: ['“0000-00-00 00:00:00.000000” value has the correct format (YYYY-MM-DD HH:MM[:ss[.uuuuuu]][TZ]) but it is an invalid date/time.'] Which implies to me it is attempting to set it to 0. My model definition is: class User(models.Model): ... updated_details = models.DateTimeField(blank=True, null=True) ... How do I get Django to set the field to the current DateTime? -

Update specific ORM object with self object attribute from filtered queryset
I'm wondering is there any option to update current ORM object from filtered queryset with a new value which comes from current object?

Maybe there is different approach? -
django admin sort calculated fields in listview
I have two models, one (Device) which has a foreign key to the other (Storage). In the admin overview of Storage I wanna be able to add a count of how many Device has pointed to each Storage.

Use Django REST framework serializer to save JSON requests to database

Django ORM: Order by dates and weekdays
I have a table that stores courses and one that stores their dates and weekdays: Course: ID, CourseDates (M2M) CourseDate: ID, Date (Date), Weekday (0-6), Full (Boolean) If its a date, weekday is NULL If its a weekday, date is NULL Only dates can be set to full (full=True) Use case: I want to order by the next occurence (date or weekday) that is not full. Challenge: Weekdays should only be considered if there is no date that is full for that day. Example: Course 1 1, Date=2021-02-12, Weekday=NULL, Full=True 2, Date=NULL, Weekday=4 (Friday), Full=False Course 2 3, Date=2021-02-13, Weekday=NULL, Full=False Expected Result: Course 2 Course 1 Explanation: Next date for Course 2: 2021-02-13 Next date for Course 1: 2021-02-19 (because 2021-02-12 is full) Question: Can this be done using SQL/Django ORM only? Does it even make sense? My current attempt (this wont work in the above example): """ The subquery annotates all CourseDates with the difference to today, orders them by days left, and in the main query we only use the first entry, which is the closest CourseDate for this course """ subquery = ( CourseDate .objects .exclude(full=True) .filter(course=OuterRef('id')) .filter(Q(date__gt=today_date) | Q(date__isnull=True)) .annotate(today=Value(today_date, output_field=DateField())) .annotate( days_until_next=Case( When(weekday__lt=today_weekday, then=6 … -
how to copy the tables of influx db ( free versione ) into postgres

Only allow a certain domain to access my Django backend
I'm currently developing an application which consists of a React frontend, which makes frequent requests to a Django backend. Both the React and Django applications are running on the same server. My problem is I wish to hide my Django backend from the world, so it only accepts requests from my React application. To do so, I've been trying several configurations of ALLOWED_HOSTS in my Django settings.py, but so far none of them seem to be successful. An example route that I wish to hide is the following: https://api.jobot.es/auth/user/1 At first I tried the following configuration: ALLOWED_HOSTS=['jobot.es'] but while this hid the Django backend from the world, it also blocked the petitions coming from the React app (at jobot.es). Changing the configuration to: ALLOWED_HOSTS=['127.0.0.1'] enabled my React app to access the backend but so could do the rest of the world. When the Django backend is inaccessible from the outside world, a get request from https://api.jobot.es/auth/user/1 should return a 400 "Bad Request" status. The error I get when the React app fails to request data from the Django backend is the following: Access to XMLHttpRequest at 'https://api.jobot.es/auth/login' from origin 'https://jobot.es' has been blocked by CORS policy: Response to preflight request … -
What is Causing Encrypted Nginx Log Lines and ERR_SSL_PROTOCOL_ERROR in Docker Compose?
I am running three docker containers in a django production environment on a google cloud VM with firewall settings open to https traffic. I am using a chained cert that I obtained from godaddy and concatenated the certs as per nginx docs. My containers are a django app, postgres, and nginx acting as a proxy in order to serve static files. I am orchestrating them using docker-compose. I also have a public URL pointing to the public IP of the google vm. When going to the endpoint in a browser I get an "ERR_SSL_PROTOCOL_ERROR" If I tail the nginx logs on the vm I get encoded log lines, like: nginx_1 | 93.173.8.110 - - [09/Feb/2021:09:02:12 +0000] "\x16\x03\x01\x02\x00\x01\x00\x01\xFC\x03\x03C\x08!\xB3d\xC76P\xE5\x I confirmed that the nginx container is up and running and started with no errors. Is there something obvious I am doing wrong? And specifically a reason my nginx log entries are encrypted and non-readable?

You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. Django
I'm getting this error whenever I'm trying to run python manage.py runserver in Django. The error: django.core.exceptions.ImproperlyConfigured: Requested setting DEBUG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. Why can that be? I think it is because my settings.py it is called base.py instead of settings.py and that's why Django doesn't detect that file as my settings file. If that's the case, how can I assign the settigns file to that base.py fiile? this is the base.py file: import os from pathlib import Path from django.urls import reverse_lazy # Build paths inside the project like this: BASE_DIR / 'subdir'.

How to run Django APScheduler on a view function
I want to run a Django view every day preferably at a specific time that calls an API and saves the data in a ForeignKey relational model. I can't use the schedule package in python because it requires infinite loop which can't run alongside a web server. Django APScheduler looks like an elegant solution though the problem is view functions take request as an argument which can't be passed to APScheduler which I need to save the data with the user's id thus I'm getting a Name error views.py def sync_data(): api_url = "" access_token = RefreshToken.response headers = { 'Authorization': 'Bearer {}'.format(access_token), 'Content-Type': 'application/json;encoding=utf-8', } user_id = request.user.id response = requests.post(api_url, data=json.dumps(body), headers=headers) r = response.json() s = Model(user=request.user, starttime = startdate , endtime = endate, field = i['value'][0]) s.save() return redirect('app:dash') scheduler.py from .views import sync_data def start(): scheduler = BackgroundScheduler() scheduler.add_jobstore(DjangoJobStore(), "default") # run this job every 24 hours scheduler.add_job(sync_data, 'interval', hours=24, name='sync_daily_data', jobstore='default') register_events(scheduler) scheduler.start() print("Scheduler started...", file=sys.stdout) How do I go about this? Appreciate any help I'll get -
Default regex django uses to validate email
recently, I started playing with Django and created a custom form for user registration. In that form to create the field for email I use something like email = forms.EmailField() I observed that address such as a@a.a is considered invalid by the form. Of course this is a nonsense email address. Nonetheless, I wonder how does Django checks for validity. I found some topics on the net discussing how to check for validity of an email address but all of them were providing some custom ways. Couldn't find something talking about the django default validator. In their docs on the email filed they specify Uses EmailValidator to validate that the given value is a valid email address, using a moderately complex regular expression. However that's not very specific so I decided to ask here. -
xmlhttprequest post not posting to view in django
I am having a login page like this which gets data authenticated from google sign-in successfully and after that I need to post the data to the login view function onSignIn(googleUser) { // Useful data for your client-side scripts: var profile = googleUser.getBasicProfile(); console.log("ID: " + profile.getId()); console.log('Full Name: ' + profile.getName()); console.log('Given Name: ' + profile.getGivenName()); console.log('Family Name: ' + profile.getFamilyName()); console.log("Image URL: " + profile.getImageUrl()); console.log("Email: " + profile.getEmail()); var id_token = googleUser.getAuthResponse().id_token; console.log("ID Token: " + id_token); alert("Token*"+id_token); //this gets executed var xhr = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { alert(this.responseText); } }; request.open('POST', '/login'); //i tried this also 'login' but not working xhr.open('POST', 'http://localhost:8000/login'); xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xhr.onload = function() { console.log('Signed in as: ' + xhr.responseText); alert("*******Token*"+id_token) xhr.send('idtoken=' + id_token); }; views def login(request): //does not get called if request.method=='POST': print("in login") print(request.body.decode()) ---more code urls.py path('/login', views.login, name="login"), path('',views.login,name="login"), I am getting no response on the view, i am not getting any error on the console also.

Distance between two coordinates in swift does not match geodjango query
I am in the process of developing a mobile application in Swift that is connected to a Python/Django backend. I have a group of objects that need to be sorted by location. Each object has a Point representing the coordinate pair. I connect to the backend from the frontend by passing in the source_latitude and source_longitude into the url parameters. I then use geodjangos with geospatial indexing for two different queries: latitude = request.query_params.get('source_latitude', None) longitude = request.query_params.get('source_longitude', None) if latitude is None or longitude is None: return queryset ref_location = Point(float(latitude), float(longitude), srid=4326) return queryset.annotate(distance=Distance('location', ref_location, spheroid=False)).order_by('distance').distinct() In my second query, I need to organize by within a certain range, which includes a radius URL parameter: return Store.objects.filter(location__distance_lte=(ref_location, D(mi=[radius input into from url parameter]))) Since the distance calculated is different for each object on each phone. I calculate the distance to display to the user on the frontend. However, there seems to be a discrepancy with the distance calculated between the frontend and the backend. For some objects that are close in distance, say 1-3 miles, the ordering of the objects is wrong. This is the frontend swift Code let currentLocation = CLLocation(latitude: Double(latitude)!, longitude: Double(longitude)!) let storeLocation = … -
Is there a way to pass in variable to <div> id in django template?
I am new to the Django template language and I am playing around with bootstrap collapses to display my items. Below is my code: {% for item in items %} <div id="accordion"> <div class="card"> <div class="card-header" id="headingOne"> <h5 class="mb-0"> <button class="btn btn-link" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne"> {{item.item_name}} </button> </h5> </div> <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordion"> <div class="card-body"> {{item.description}} </div> </div> </div> </div> {% endfor %} This is taken from the Bootstrap documentation for collapse, here. In this implementation, all of the items passed in would have the same id, collapseOne. So whenever I click on an item, any item, it would collapse/uncollapse every item on the page. I've tried id="collapse{{item.item_name}}" but that doesn't seem to work. Is there a way to pass in variables in <div> id?
