django listview pagination is too slow on large dataset
I have a django listview that shows filtered data from Catalogue. It works fine on small database, but when database is too large, it takes too long time to return results. views.py: class all_ads(generic.ListView): paginate_by = 12 template_name = 'new_list_view_grid-card.html' def get_queryset(self): city_district = self.request.GET.getlist('city_district') usage = self.request.GET.get('usage') status = self.request.GET.get('status') last2week = datetime.datetime.now() - datetime.timedelta(days=14) status = status.split(',') if usage: usage = usage.split(',') else: usage = ['1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','24','25','26','27','28','29','30','31'] intersections = list(set(status).intersection(usage)) type_q = (Q(type__in=intersections) & Q(type__isnull=False)) cat_ids = list(models.Catalogue.objects.filter( Q(*[Q(city__contains=x) for x in city_district], _connector=Q.OR) | Q(*[Q(district__contains=x) for x in city_district], _connector=Q.OR) ).values_list('pk', flat=True)) result = models.Catalogue.objects.filter( Q(datetime__gte=last2week), type_q, pk__in=cat_ids ).distinct().order_by('-datetime').prefetch_related('type') return result models.py: class Catalogue(models.Model): city = models.CharField(db_index=True,max_length=100, null=True) district = models.CharField(db_index=True,max_length=100, null=True) type = models.ManyToManyField(Type, db_index=True) class Type(models.Model): name = models.CharField(max_length=100, db_index=True) def __str__(self): return self.name And this is template.html: {% for Catalogue in catalogue_list %} "do something" {% endfor %} -
Django Broken Pipe Message
When creating an instance in Django Admin, I get the 'Broken pipe' message in the terminal. The instance can be seen in Django Admin and everything seems to be okay.

Django - The current path, job/all, matched the last one. - But it still returns 404
When I go to this URL http://127.0.0.1:8000/job/all I am always receiving a 404 error with this message: 404 Django Error screenshot However, when I just go to http://127.0.0.1:8000/ or http://127.0.0.1:8000 it always finds the / (index) route correctly regardless if there is a trailing slash, or not. This issue seems to only happen with the /job/WHATEVER_ELSE_GOES_HERE URLs. I have the following URLs setup: My jobs app urls.py: from django.urls import path from .views import * urlpatterns = [ path('', index, name="index"), path('job/<int:job_id>', job_details, name="job_detail"), path('job/all/', all_jobs, name="all_jobs"), path('job/add/', add_job, name="add_job"), path('job/my_posted_jobs/', my_posted_jobs, name="my_posted_jobs"), path('job/delete/<int:job_id>', delete_job, name="delete_job"), path('job/search', search_job, name="search_job"), path('job/apply_for_job/<int:job_id>', apply_for_job, name="apply_for_job") ] My project's urls.py: from django.contrib import admin from django.urls import path, include from django.contrib.auth import views as auth_views from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('admin/', admin.site.urls), path('', include('jobs.urls')), path('user/', include('users.urls')), path('payments/', include('payments.urls')), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) In the error message (screenshot) it also says this: The current path, job/all, matched the last one. How come it matches a URL but returns 404? How do I fix it? Thank you -

No such File or directory "optimize-images"
I am using optimize-images (PyPi) library for optimizing images in a folder. (which is generated dynamically for every users). (Django Project) I have installed optimize-images using pip. Since, its a long running task i am using celery to first import the images to a directory and then running a command (optimize-images) on that directory for compressing all images. os.chdir(r'/home/django/image-io/accounts/'+dynamic_user+'/optimized/') cwd = os.getcwd() print("CURENT WORKING DIRECTORY") print(cwd) p=subprocess.Popen([r"optimize-images", cwd]) p.wait() where , dynamic_user is a user_name (string) optimized/ is the directory where all images are stored. I am not able to understand , why it says this error "No such file or directory: 'optimize-images'" Since, optimize-images is a command line utility and not a folder/file.

Implement multi user login in Nuxt
I am using Nuxt 2.15 and Django 3.2.3. I would want to implement a multi user login with Nuxt. In the django project, I have an single model with an option of either a student or a teacher. On the frontend (NUXT), user can register as either a student or a teacher. When it gets to the login, if a user is a teacher, it should be directed to a teachers and if a student, to student's page. I would be grateful with any assistance on the latter case. -

Django database routers - how do you test them, especially for migrations?
I've read the documentation on database routers in Django 2.2. I more or less understand the concept - including keeping certain tables together - except that it seems somewhat tricky to do in practice. I have defined the routers in settings: DATABASES = { "default": { "ENGINE": constants.POSTGRES_ENGINE, "NAME": constants.SYSDBNAME, ... }, "userdb": { "ENGINE": constants.POSTGRES_ENGINE, "NAME": constants.USERDBNAME, } DATABASE_ROUTERS = [ #the user database - userdb - which gets the auths and user-related stuff "bme.websec.database_routers.UserdbRouter", #the default database - sysdb "bme.websec.database_routers.SysdbMigrateRouter", ] Ideally I would use unit tests to submit all my models one by one to the routers' allow_migrate, db_for_read, db_for_write methods, and for each call, verify that I got the expected test results. But is there a way to do that? I suppose I can use models = django.apps.apps.get_models( include_auto_created=True, include_swapped=True ) and then drive those methods calls from unittests. But to take just def allow_migrate(self, db, app_label, model_name=None, **hints): How do I know when to have **hints and whether model_name is always provided or not? And most importantly, how do I simulate what the master router ultimately decides as stated in the doc (my emphasis)? Among other things, it doesn't rely on just one router, it … -

Getting 403 Forbidden error on post requests when serving django app on Amazon cloud front through heroku
I have a django app deployed in heroku, which was working previously, however after adding the Edge add-on, which serves your static files from Amazon cloudfront for caching, all of my post requests are getting 403 errors. I do pass the csrf token correctly, as my post requests still work when not served from cloudfront, but on cloudfront I am getting the error that the CSRF Verification failed It also mentions that the referer header is missing, however I can see referer specified in the request headers in the network tab of the developer tools. Any idea what I am missing here? -
