Django: How to manage different versions of the settings.py
We need to have different settings for different regions. For example: settings_us.py settings_uk.py settings_au.py UK and AU are copied from settings_us.py. Most parts of the settings are the same across all regions except for some parameters like reading DB endpoints that need to be changed. Having three versions of the settings is very hard to manage. I wonder if there is a cleaner way to manage these settings? Thank you. -
django only redirecting to base url not
I am trying to redirect back to the url that made a request before request was made to an external login service, using amiddleware. The solution I currently have only redirects to the base url (http://127.0.0.1:8000) When I go to, http://127.0.0.1:8000/asasas I am redirected to https://external_login/login?abc=def&the_url=http://127.0.0.1:8000/asasas which is correct, after a successful login, I am redirected to http://127.0.0.1:8000 instead of http://127.0.0.1:8000/asasas. Is there any way I can redirect to the calling URL before temporarily redirect to external login? Middleware class AttemptRedirect(object): def __init__(self, get_response): self.get_response = get_response def __call__(self, request): url = request.build_absolute_uri() if 'username' not in request.session: if request.GET.get('xyz'): validate = 'https://external_login/validate?abc=def&xyz={}&the_url={}'.format(request.GET.get('xyz'), url) req = urllib.request.Request(validate) gcontext = ssl.SSLContext() response = urllib.request.urlopen(req, context=gcontext).read() result = response.decode('utf-8') if result[0:3] == 'yes': request.session['username'] = result[3:] new_url = urlparse(request.build_absolute_uri()) query = parse_qs(u.query) query.pop('xyz', None) new_url = new_url._replace(query=urlencode(query, True)) new_url = urlunparse(new_url) return redirect(new_url) else: return redirect("https://external_login/login?abc=def&the_url={}".format(url)) else: response = self.get_response(request) return response -
Django query depth search
I have an djangorestframework app where I have data from external source which I cannot affect. There is tier structure with employees and supervisors. models.py : class Employee(models.Model): name = models.CharField(max_length=100) supervisor = models.CharField(max_length=100) date = models.DateField(max_length=100) I know this is wrong and the supervisor should be foreign key, but that is not under my controll. What I need is that I get a request for high level supervisor, so the final query will return all employees for the requested supervisor and if some of the employee is also a supervisor then return all his employees till it comes to the lowest level where the employees are not supervisors. It should work like Depth-first search. Is there any way to return this query? -

How to check index numbers from database using Django?
I've got a system built in Django which receives data. I store the data as follows: id | sensor | message_id | value ----+--------+------------+------- 1 | A | 1 | xxx 2 | A | 2 | xxx 3 | A | 3 | xxx 4 | B | 1 | xxx 5 | B | 2 | xxx 6 | B | 4 | xxx As you can see, the message_id increases per sensor with every subsequent message that we receive. The message_id number 3 is missing for sensor B though. I now want a way to know about this when it happens. So I want do a check whether a message is missing in the past five minutes. The simplest way I thought of doing this is by querying the message_id for one sensor and then loop over them to check whether any number is skipped. Something like this: five_minutes_ago = datetime.now() - timedelta(minutes=5) queryset = MessageData.objects.filter(created__gt=five_minutes_ago).filter(sensor='B').order_by('message_id') last_message_id = None for md in queryset: if last_message_id is None: last_message_id = md.message_id else: if md.message_id != last_message_id + 1: missing_messages = md.message_id - last_message_id - 1 print(f"{missing_messages} messages missing for sensor {md.sensor}") But since I've got hundreds of sensors … -
Django wkhtmltopdf loading stuck
same issue. Just checking if it has been solved.

Django - Questionnaire - ModelFormSet - Cannot assign
Alright, so I'm following a tutorial on creating a small questionnaire with Django. A User can create a survey with different multiple choice questions. Since they're multiple choice questions, users can also set the options for the questions. A "survey taker" can then start a survey, select his or her preferred questions and submit the form. I would like to only show a single question per page so I'm trying to work with modelformset_factory and implement pagination using the build in paginator. The form is rendered correctly and a user can submit an answer, however, the form fails before "formset.is_valid()", I just can't figure out why; ValueError at /surveys/1/submit/4/ Cannot assign "'2'": "Answer.option" must be a "Option" instance. So I can not save an integer and I somehow have to relate the integer with the id from the option model... But I can't access cleaned_data yet so I guess I'm missing something here. Did I forget something within the formset? I've been staring at this for a while now so any help is appreciated. #Views def submit(request, survey_pk, sub_pk): # Let's retrieve the survey which is created by the survey-taker try: survey = Survey.objects.prefetch_related("question_set__option_set").get( pk=survey_pk, is_active=True ) except Survey.DoesNotExist: raise … -
Pagination with graphql and django
I am using react(fe), django (be) and graphql. Currently I send request when I reach bottom of my page to fetch more "posts" to my infinitescrolling feed. In django-graphene this would work like Return Post.objects.all() [offset, offset+limit]. But what should I do if for example my return statement weren't as easy as just fetching all posts? What if I need to return the posts in a sorted way that they aren't already in the DB? Right now, I am doing it like Return custom_sort(Post.objects.all())[offset, offset+limit]. Still working, but I need to sort them on every request (I think, if django aren't cashing it). How would one do this so I only need to sort them once, and then save those values for say a minute so I doesn't need to sort everytime I request? -

Moving from function view to class based view
I have already running table with quite a lot of data. This table was designed years ago with not very clear assumption. Table contains list of "services" we own. There is column 'service_id' which points to given entity. This entity has many instances. In fact, each month, we add new row (new instance), with new data but same 'service_id' for given entity. Now, let's move to Django. I use generic class based views, like ListView, CreateView, DetailView, etc. For this only specific case I need to use function view. How to rewrite this function view to class based view? VIEW: def EsiDetailedView(request, requested_service_id): last_object=Esi.objects.filter(service_id=requested_service_id).aggregate(Max('id')) last_object_id=last_object.get("id__max") last_service=Esi.objects.get(id=last_object_id) args={} args['service'] = Esi.objects.filter(service_id=requested_service_id).order_by('-end_date') args['details'] = last_service #to show details of single service return render(request, 'esi/esi_details.html', args) URLS: urlpatterns = [ path('<int:requested_service_id>/', EsiDetailedView, name='esi-detail') ] -

Config.js file in django-ckeditor not applying configurations
I have been trying to style Django-CKEditor by modifying the config.js file, all to no avail; my custom configuration in config.js is not working. I have gone as far as manually modifying the default CSS files, but all these modifications fail to work as well. Although when I use Chrome's developers tool to make some modifications, they all worked. My question is, is the config.js file not usable in Django? config.js CKEDITOR.editorConfig = function( config ) { // Define changes to default configuration here. For example: // config.language = 'fr'; // config.uiColor = '#AADC6E'; config.uiColor = '#000000'; config.enterMode = CKEDITOR.ENTER_BR; config.width = "100%"; config.height = "300"; config.extraPlugins = 'autogrow'; config.autoGrow_minHeight = 250; config.autoGrow_maxHeight = 600; }; settings.py CKEDITOR_UPLOAD_PATH = "images/avatar/" CKEDITOR_IMAGE_BACKEND = 'pillow' CKEDITOR_RESTRICT_BY_USER = True CKEDITOR_CONFIGS = { 'default': { 'skin': 'moono-lisa', 'toolbar_Basic': [ ['Source', '-', 'Bold', 'Italic'] ], 'toolbar_Custom': [ {'name': 'styles', 'items': ['Styles']}, {'name': 'basicstyles', 'items': ['Bold', 'Italic', 'Underline']}, {'name': 'colors', 'items': ['TextColor']}, {'name': 'links', 'items': ['Link', 'Unlink', 'Anchor']}, {'name': 'insert', 'items': ['Smiley']}, ], 'toolbar': 'Custom', }, } HTML <script type="text/javascript" src="{% static 'ckeditor/ckeditor/ckeditor.js' %}"></script>
