Very slow database query migrating from django 1.8 to django 3.2
I migrated a project from django1.8 to django3.2. I'm using the same database but the function I use to build a report is four times slower (8 seconds on Django1.8 and 30/40 seconds with django3.2). The database is MySQL version 5.7 (I also tried version 8.0.32 but nothing changed). This is the query: qs = PartitaDanno.objects.filter(incarico__cliente_intestatario_fattura_id=8006 ).select_related('incarico', 'anagrafica_assctp', 'incarico__naturaincarico' ).prefetch_related('rate' ).order_by('-incarico__anno', '-incarico__numero', 'pk') PartitaDanno is a table with 16000 rows and the model has 215 fields (I know..I didn't write it). The result of this query are just 1700 rows..a very small result. The unusual thing is that even if I use a simple query on this model like qs = PartitaDanno.objects.filter(incarico__cliente_intestatario_fattura_id=8006) It takes 20 seconds to iterate through result of this basic query..I don't understand. The raw sql query is the same in both versions of Django. This is the first queryset raw query: SELECT `sinistri_partitadanno`.`id`, `sinistri_partitadanno`.`created`, `sinistri_partitadanno`.`modified`, `sinistri_partitadanno`.`incarico_id`, `sinistri_partitadanno`.`tipo`, `sinistri_partitadanno`.`tipologia_controparte`, `sinistri_partitadanno`.`fase`, `sinistri_partitadanno`.`competenza_giurisdizionale`, `sinistri_partitadanno`.`soggetto`, `sinistri_partitadanno`.`anagrafica_assctp_id`, `sinistri_partitadanno`.`luogo`, `sinistri_partitadanno`.`compagnia_id`, `sinistri_partitadanno`.`riferimento_compagnia`, `sinistri_partitadanno`.`tipo_di_danno`, `sinistri_partitadanno`.`tipo_lesioni`, `sinistri_partitadanno`.`tipologia_vittima`, `sinistri_partitadanno`.`modello_veicolo`, `sinistri_partitadanno`.`targa_veicolo`, `sinistri_partitadanno`.`riserva_iniziale`, `sinistri_partitadanno`.`riserva_parziale`, `sinistri_partitadanno`.`data_richiesta_danni_ctp`, `sinistri_partitadanno`.`reiezione_cautelativa`, `sinistri_partitadanno`.`data_reiezione_cautelativa`, `sinistri_partitadanno`.`importo_richiesto_da_ctp`, `sinistri_partitadanno`.`data_incarico_nostro_perito`, `sinistri_partitadanno`.`tipologia_perizia`, `sinistri_partitadanno`.`nominativo_perito`, `sinistri_partitadanno`.`data_perizia_negativa`, `sinistri_partitadanno`.`motivazioni_perizia_negativa`, `sinistri_partitadanno`.`data_interlocutoria_inviata_dal_perito`, `sinistri_partitadanno`.`importo_stimato_dal_perito`, `sinistri_partitadanno`.`data_ricezione_perizia_dal_nostro_perito`, `sinistri_partitadanno`.`riparazione_antieconomica`, `sinistri_partitadanno`.`data_incarico_medico_legale`, `sinistri_partitadanno`.`data_ricezione_perizia_dal_nostro_medico_legale`, `sinistri_partitadanno`.`data_invio_offerta_tramite_transazione_quietanza`, `sinistri_partitadanno`.`data_reiezione_indennizzo_risarcimento`, `sinistri_partitadanno`.`pagamento_parziale`, `sinistri_partitadanno`.`capitale`, `sinistri_partitadanno`.`data_pagamento_capitale`, `sinistri_partitadanno`.`anagrafica_patrocinatore_id`, `sinistri_partitadanno`.`tipo_patrocinatore`, `sinistri_partitadanno`.`cf_piva_patrocinatore`, `sinistri_partitadanno`.`numero_rif_patrocinatore`, `sinistri_partitadanno`.`spese_legali`, `sinistri_partitadanno`.`data_pagamento_spese_legali`, `sinistri_partitadanno`.`integrazione_capitale`, `sinistri_partitadanno`.`data_pag_integraz_capitale`, `sinistri_partitadanno`.`integrazione_spese_legali`, `sinistri_partitadanno`.`data_pag_integraz_spese_legali`, `sinistri_partitadanno`.`note_generali`, `sinistri_partitadanno`.`note_pagamenti`, `sinistri_partitadanno`.`cessione_del_credito`, `sinistri_partitadanno`.`veicolo_sostitutivo`, … -
Model not detected by Django, even with `app_label` referencing to an existing app
I have a Django project with an application called data. The app is installed in the INSTALLED_APPS as follows: 'base.apps.MyAppConfig' with the AppConfig: class MyAppConfig(AppConfig): name = 'application' verbose_name = 'My App' label = 'application' path = f"{os.environ.get('APP_DIR')}/application" default = True I have the models defined like this: ### data/models/base/basemodel.py class MyBaseModel(models.Model): # ... fields ... Meta: app_label: `application` However, Django is not finding the models, and if I run makemigrations Django responds No changes detected, and on migrate, the app application does not appear on the Operations to perform. The Model should be detected so the Django detects migrations to apply === Context: Django Application reference: doc Django Models reference: doc -

Django template - global template namespace as parameter value for inclusion tag
I have a Django template for rendering tables which I can successfully include in my other templates. I takes a prefix and a namespace parameter, where the namespace is a key within the rendering context: {% include "table.html" with prefix=name|add:"_" namespace=rubric1 %} and in the template I use e.g.: {% for object in namespace.object_list %} ... {% endfor %} My rendering context looks like this: context = { 'some_var': ..., 'rubric1': { 'object_list': ..., 'direction': ..., 'orderby': ..., 'total': ..., 'page': ..., ... }, 'rubric2': { 'object_list': ..., ... }, } Now I want to use this template in a ListView, where those keys live at the root of the context namespace: context = { 'some_var': ..., 'object_list': ..., 'direction': ..., 'orderby': ..., 'total': ..., 'page': ..., ... } How do I tell the inclusion tag to use the root of the rendering context as namespace? Is there a special variable for this? E.g.: {% include "table.html" with prefix=name|add:"_" namespace=global_template_namespace %} Or can i somehow use a with context? E.g.: {% with global_template_namespace as ns %} {% include "table.html" with prefix=name|add:"_" namespace=ns%} {% endwith%} I have also thought about simple_tag that directly returns the context, but couldn't manage to use … -

Problem serving Django "polls" tutorial under lighttpd: 404 page not found
I am following the Django polls tutorial, which is working 100% with the built-in development server (python3 manage.py runserver). I have set up lighttpd to serve django through UWSGI and that seems to be working fine but for one glitch: the URL passed to django seems to have been modified. My lighttpd configuration is basically this: ... server.modules += ("mod_scgi","mod_rewrite") scgi.protocol = "uwsgi" scgi.server = ( "/polls" => (( "host" => "localhost", "port" => 7000, "check-local" => "disable", )) ) The Django tutorial mapping looks like: # tutorial1/urls.py urlpatterns = [ path('polls/', include('polls.urls')), path('admin/', admin.site.urls), ] # polls/urls.py app_name = 'polls' urlpatterns = [ path('', views.IndexView.as_view(), name='index'), path('<int:pk>/', views.DetailView.as_view(), name='detail'), path('<int:pk>/results/', views.ResultsView.as_view(), name='results'), path('<int:question_id>/vote/', views.vote, name='vote'), ] However when I hit http://localhost:8080/polls/ in the address bar, it produces an 404 error. If I add an extra /polls to the URL then it works just fine. My goal with this exercise is to be able to serve this app switching from and to both servers without needing to modify configuration files each time. What do I need to do on the lighttpd.conf side to make lighttpd interchangeable with Django's own internal dev server? I have tried to add the following url.rewrite … -
Django - Iterating over Raw Query is slow
I have a query which uses a window function. I am using a raw query to filter over that new field, since django doesn't allow filtering over that window function (at least in the version I am using). So it would look something like this (simplified): # Returns 440k lines user_files = Files.objects.filter(file__deleted=False).filter(user__terminated__gte=today).annotate( row_number=Window(expression=RowNumber(), partition_by=[F("user")], order_by=[F("creation_date").desc()])) I am basically trying to get the last not deleted file from each user which is not terminated. Afterwards I use following raw query to get what I want: # returns 9k lines sql, params = user_files.query.sql_with_params() latest_user_files = Files.objects.raw(f'select * from ({sql}) sq where row_number = 1', params) if I run these queries in the database, they run quite quickly (300ms). But once I try to iterate over them or even just print them it takes a very long time to execute. Anywhere from 100 to 200 seconds even though the query itself just takes a little bit less than half a second. Is there anything I am missing? Is the extra field row_number in the raw query an issue? Thank you for any hint/answers. (Using Django 3.2 and Python 3.9) -
Django ManyToMany trhough summary calculation

How to filter the latest amended laws in django admin site?

Optimize Django ORM query to get object if a specific related object does not exist
I have the following table structures: class Library: id = models.CharField(...) bookcase = models.ForeignKey( Bookcase, related_name="libraries" ) location = models.ChoiceField(...) # Other attributes... class Bookcase: # some attributes type = models.ChoiceField(..) class Book: bookcase = models.ForeignKey( Bookcase, related_name="books" ) title=models.CharField(...) status=models.ChoiceField(...) # borrowed | missing | available Say if I want to get all Library objects that does not have a book with title "Foo" that is NOT missing, how can I optimize this query? I have the following: libraries = Library.objects.select_related('bookcase').filter(location='NY', bookcase__type='wooden') libraries_without_book = [] for library in libraries: has_non_missing_book = Book.objects.filter( bookcase=library.bookcase, title="Foo", ).exclude(status='missing').exists() if not has_non_missing_book: libraries_without_book.append(library.id) Unfortunately, this performs an extra query for every Library object that matches the initial filtering condition.

Nesting Django QuerySets
Is there a way to create a queryset that operates on a nested queryset? The simplest example I can think of to explain what I'm trying to accomplish is by demonstration. I would like to write code something like MeterReadings.objects.filter(radio=1).objects.filter(meter=1) resulting in SQL looking like SELECT * FROM ( SELECT * FROM MeterReading WHERE radio=1 ) WHERE meter=1; More specifically I have a model representing readings from sensors class Sensor(models.Model): sensor=models.PositiveIntegerField() timestamp=models.DatetimeField() reading=models.IntegerField() With this I am creating a queryset that annotates every sensor with the elapsed time since the previous reading in seconds readings = ( SensorReading.objects.filter(**filters) .annotate( previous_read=Window( expression=window.Lead("timestamp"), partition_by=[F("sensor"),], order_by=["timestamp",], frame=RowRange(start=-1, end=0), ) ) .annotate(delta=Abs(Extract(F("timestamp") - F("previous_read"), "epoch"))) ) I now want to aggregate those per sensor to see the minimum and maximum elapsed time between readings from every sensor. I initially tried readings.values("sensor").annotate(max=Max('delta'),min=Min('delta'))[0] however, this fails because window values cannot be used inside the aggregate. Are there any methods or libraries to solve this without needing to resort to raw SQL? Or have I just overlooked a simpler solution to the problem? -
How to setup django with lighttpd?
I have a live website that is running under lighttpd. I now have a sub-domain that I want to run under django. I do not want to move to Apache as I don't currently have the resources to support two production web servers. The django part is actually working well with the django builtin development server so now I just need to port it into production. It seems that all documentation to setup django with lighttpd is over 10 years old and uses fastcgi that from what I can see was deprecated and removed from django. The new docs point to use wscgi - scgi under lighttpd. But even that is being hard to get any documentation. Do I need to run uwsgi and use that to serve the pages to mod_scgi? Or should I use gunicorn? I am sort of at a loss on what to do. Suggestions welcome! -
Django: How to Filter Model with "where" clause to display in list admin related objects

How to make Celery + Django + Pytest work together
Trying to test an endpoint that has a celery task. Celery tasks don't seem to run in the test. django==4.1.5 celery==5.2.7 pytest==7.2.1 pytest-django==4.5.2 An endpoint: def do_some_stuff(blah: Blah) -> Blah: res = cool_task.apply_async(kwargs={ 'cool_id': int(pk), 'config': config, 'name': RESUBMIT.value, }, link=update_status.si( cool_id=int(pk), new_status="why is this so hard", ) ) [...] A test: @pytest.mark.django_db def test_my_thing(django_client: Client) -> None: [...] response = django_client.post(f"/api/myendpoint/{mything.id}/do_some_stuff/") It hits the endpoint. Gets a 202 back as expected. But celery doesn't seem to be picking up the task in the test. The update_status method updates the db, and I'm not seeing that happen. I've tried creating a celery app in the test, creating a worker in the test, changing the test to use the main DB instead of the test db, setting the override_settings to "BROKER_BANDEND='memory'". I'd like a full working example. It seems kind of basic but it's eluding me. I don't understand what combination of fixtures and overrides I need for this to work. Seems to work when I actually call the application.
