Filtering posts from yesterday, last week and last month doesn't work
I am using a simple form to filter posts based on yesterday, last week, last month and last year. And this is the view, how I wanted it to be handled: def search(request): # filter by date added list_date = request.GET.get('list_date') today = timezone.now() if list_date: if list_date == 'yesterday': yesterday = today - timedelta(days=1) print(yesterday, 'yesterday') queryset = queryset.filter(listing_date__lt=yesterday) print(queryset) elif list_date == 'lastweek': lastweek = today - timedelta(weeks=1) queryset = queryset.filter(listing_date__lt=lastweek) elif list_date == 'lastmonth': lastmonth = today - timedelta(days=30) queryset = queryset.filter(listing_date__lt=lastmonth) elif list_date == 'lastyear': lastyear = today - timedelta(days=365) queryset = queryset.filter(listing_date__lt=lastyear) context = { 'listings': queryset, } return render(request, 'listing/listings.html', context) and in model: listing_date = models.DateTimeField(auto_now_add=True). I printed yesterday and queryset above and it returns this in console: 2020-05-26 03:54:45.107533+00:00 yesterday <QuerySet []> I filtered posts by yesterday, but why the queryset is empty, although I am sure posts were created yesterday? -
How to get data from other table in django with Foreign Key(New to Django)

Pass dynamic form values in defaults attribute of update_or_create method in django
I want to create a post using foreign key if the post is not existed and i want it to be updated using the same foreign key if it already existed using the identical form. I had used create_or_update method of django but I had not got insight about it. What should we used in the default attribute of create_or_update method of django. I want the form data to be posted what user enters into the form. models.py class EventDetail(models.Model): event = models.ForeignKey(Event,default=None,on_delete=models.CASCADE) event_summary = models.CharField(max_length=255,null=True) event_details = RichTextUploadingField(null=True) timestamps = models.DateTimeField(auto_now_add=True,auto_now=False) updated = models.DateTimeField(auto_now_add=False,auto_now=True) I have Event model and EventDetail Model. The Event Detail Model consists of event as foreign key. After creating event, the url redirects to eventdetail where the form for posting event summary and event details are available. I want the form to be created and posted dynamically by user's input if the summary and details are not posted before and I want the form to be updated if the data are already available before i.e The data should be updated. I also want the foreign key to be stored automatically after the event details has been created. -

Is there a way to allow different templates to cross-read content in Django?
I'm working on a project, that pulls data from local database and organizes it into a directory, then calls a API to display the price of each item, this is how I implemented it in Views.py class MarketgroupsListView(generic.ListView): model = Marketgroups context_object_name = 'marketgroups' template_name = 'sde/marketgroups_list.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) pk = self.kwargs['pk'] context['marketgroups'] = Marketgroups.objects.filter(parentgroupid=pk).order_by('marketgroupid') #get marketgroups list context['invtypes'] = Invtypes.objects.filter(marketgroupid=pk).order_by('typeid') #get items list return context class InvtypeDetailView(generic.DetailView): model = Invtypes def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) pk = self.kwargs['pk'] url = '/api/typeid={0}'.format(pk) response = requests.get(url) context['data'] = xmltodict.parse(response.content)['price'] return context This works, but the price data can only be showed in the InvtypeDetailView. I want MarketgroupsListView can read and display the price data too so people can check the price data for entire list of items at once. But I don't know how to do that. I tried putting the API calling code into class MarketgroupsListView, but it only gets the pk of the current URL which is a marketgroups' not a invtypes So is there a way to cross-read content between different views or different templates? Or are there other solutions? -
Is it safe to reuse multiple models with the same generic view?
I have a project with around 60 models so creating a unique Detail, Create, Update, Delete APIView for each would be a lot of wasted resources (or so it feels like). Would it be better performance-wise (or safe?) to simply create a generic view that could cycle between each model like so? _CLASSES = <Dictionary of my classes> class GenericModelView(APIView): def get(self, request, model_name): # model_name would be a required part of the URL. model_class = _CLASSES[model_name] serializer_class = model_class.serializer_class # I would instantiate a serializer for each model_class return Response(serializer_class(model_class.objects.all()).data) -

Currently, all the users with and without login can view the media via http://127.0.0.1:8000/media/image1.jpg but what I want is that if the user is not login, they cannot view the pictures in the media with hardcoding the URL. I dont know if django can do this function because I cannot find related question in the internet. -

Django: translating URLS patterns not working
I'm working with Django 2.2, and it's the first time I use it in a real project. I'm trying to translate my site between two languages (english and spanish) and everything was going well. Text inside templates translates fine, and I even created a button to switch languages, but I can't translate URL patterns. I followed the django docs for Translating URL patterns but they don't get translated. I don't know if I'm missing something. I would really appreciate your help. Here's my main urls.py file: from django.conf.urls.i18n import i18n_patterns from django.contrib import admin from django.urls import include, path urlpatterns = [ path('i18n/', include('django.conf.urls.i18n')), path('admin/', admin.site.urls), ] urlpatterns += i18n_patterns( path('',include('landing_page.urls')), ) Landing page urls.py file: from django.urls import include, path from django.utils.translation import gettext_lazy as _ from . import views urlpatterns = [ path('', views.index, name='index'), path(_('about'), views.about, name='about'), path(_('contact'), views.contact, name='contact'), ] Of course I already created entries for these translations on my locale files. It doesn't throw me any error, I just get the URL with the prefix, but the "page name" on it doesn't change. -
Celery Setting Up Multiple Queues/Workers on Heroku
New to celery here and I have a project that uses it to run periodic tasks. Some tasks take some time and are lower priority so I'd like to move them to a slow queue. However, when I setup two Queues, I notice only one is active - inspect().active_queues() shows the slow queue is running all of the tasks. Now this is strange to me because I am only defining @app.task(queue=Queues.BACKGROUND_CRAWL) on a couple of tasks and tasks without that queue seem to be getting processed on that queue. I've looked through the heroku docs and celery docs and was surprised it was so hard to figure out what was going wrong with the setup. Part of me thinks it's how I am setting up the queues in my procfile. Do I need two workers, or can one worker leverage two queues? I also thought without defining -Q on the first worker it would setup the default celery queue. My procfile - worker: celery worker -A workers.celery.app worker: celery worker -A workers.celery.app -Q background_crawl_queue beat: celery --app=workers.celery.app beat My Celery App looks like - app = Celery( "app", broker=config("REDIS_URL"), backend=config("REDIS_URL"), redbeat_redis_url=config("REDIS_URL"), ) class Queues: DEFAULT = app.conf.task_default_queue BACKGROUND_CRAWLS = "background_crawl_queue" … -
Django RelatedManager: Get currently selected element's value
I have a model that has a duration value, and a durations object, which in turn has multiple duration_mins values inside. The root-level duration acts as a fallback if the durations object is empty. Endpoint response is something like this: { "id": 1, "name": "Track Name X", "duration": 10, "durations": [ { "id": 218, "duration_mins": 10 }, { "id": 219, "duration_mins": 15 }, { "id": 220, "duration_mins": 20 } ] } The main idea is to have a sum of "Minutes listened". Right now, we are doing self.total_sec += single.duration Which correctly adds the fallback, root-level duration. What I want to do is add the current duration value (sent by the client). ie: if the user selected the 20 min. duration. I tried the following: if single.durations: self.total_sec += single.durations.get().duration_mins else: self.total_sec += single.duration Which obviously doesn't work, but explains what I'm trying to accomplish. The error I'm getting is either: AttributeError: 'RelatedManager' object has no attribute 'duration_in_minutes' or, if I append .get() [...]MultipleObjectsReturned: get() returned more than one Duration -- it returned 3! Can anybody tell me how to get the currently selected duration? (Assuming the client is sending the corresponding duration id) Thanks! -
Heroku/Django: Project isn't migrating, throws error about missing tables when you run manage.py migrate

Pictures Showing on Heroku site but not Local Host
The users profile pictures are loading fine on https://rossdjangoawesomeapp2.herokuapp.com/ but when I use http://localhost:8000/ none of them are loading. The problem only occurred when I uploaded my site to Heroku / AWS. I tried un doing some of the changes to the code. I tried getting it back to a state where localhost was working fine. But then I ended up coming into more error messages. And my difficulty now is I don't really know where to begin looking for advice on how to fix the issue.

How to provide image path in "main.css" in Django?
I am trying to build an app in Django, I have created a home page, the statics paths I have set for the project working fine. I am able to render HTML(index.html) associated CSS (main.css) and images perfectly except an image "banner.jpg". For other images, I have set path as we usually do in Django, <img src="{% static 'images/image1.jpg' %}" alt="" /> For the banner of the home page, I tried to set a path in CSS something like given below. main.css #banner { background-color: #e5474b; color: #f2a3a5; padding: 13em 0 11em 0; background-color: #0c0c0c; background-image: url("../images/banner.jpg"); background-size: cover; background-repeat: no-repeat; background-position: 15% left; text-align: left; position: relative; z-index: 9999; } or #banner { background-color: #e5474b; color: #f2a3a5; padding: 13em 0 11em 0; background-color: #0c0c0c; background-image: url("{% static 'images/banner.jpg' %}"); background-size: cover; background-repeat: no-repeat; background-position: 15% left; text-align: left; position: relative; z-index: 9999; } but both the methods never work, however when I set path "url("../images/banner.jpg")" without Django it works perfectly and renders the image in the background. Where should I make the changes to correct this problem? Thank you. -
