How to use a variable as character length parameter inside a regular expression [duplicate]
I have a regular expression pattern to find words longer than a certain amount of characters: pattern = r"\w{14,}" where i want the 14 to be dynamic. How can i insert a variable as a character length parameter inside a regular expression? I tried with no success: length = 14 pattern = re.compile(r"\w{" + str(length) + ",}") The pattern is then used as a query in a Django model as: module_list = Contentmodule.objects.filter( # Q(json__text__iregex = r"\w{14,}") Q(json__text__iregex = pattern) ) and i get the error: sqlite3.InterfaceError: Error binding parameter 1 - probably unsupported type. -
why doesn't the clean method see field in forms?
I'm facing an issue with my forms in Django. I've created something like this: class EventForm(forms.ModelForm): class Meta: model = Event fields = [ "name", "start_date", "end_date" ] def clean(self): start_date = self.cleaned_data["start_date"] end_date = self.cleaned_data["end_date"] if start_date > end_date: raise ValidationError("Start Date cannot be great than End Date") elif start_date == end_date: raise ValidationError("The dates must be different.") def clean_start_date(self): start_date = self.cleaned_data["start_date"] if timezone.now() > start_date: raise ValidationError("The start date of the event must be after today.") return start_date When I tried to test it, something weird is happening. So, when I tried to input a start_date that is after today, I get the following message: start_date = self.cleaned_data["start_date"] KeyError: 'start_date' It looks like clean() doesn't see the start_date. But why? -

PostgreSQL + Django update large table taking ages to run a simple update
I have a table with around 47millions entries. I need to update this table for around 3mil entries very fast, for this I use type_id and an int inside a range to select records and then update the value on another field, while excluding another record. UPDATE "table_name" SET "changes" = 12 WHERE ("table_name". "type_id" = 78 AND "table_name"."rank" BETWEEN 2 AND 2238079 AND NOT ("table_name"."id" = 55423921)) This query was automatically generated by Django using the update method on a QuerySet, but it follows the bahavior described above and can be changed to what ever is more efficient. The reason I store all those records in the same table is to dynamically add new type_id inside without having to create a new table for each (assuming doing so would improve the speed). Currently the table has multiple indexes, but let's list the fields first: id (PK); type (foreign key containing ID + type name); score (BigInt); score_data (jsonb fr metadatas); changes (IntField); rank (IntField, used for range selection); user (foreign key for the user related to this record); There are different indexes : BTree for field score and rank type for it's PK, probably a BTree (it's the default … -
Optimal model structure for a Django-driven spare parts website
I am developing a website on Django for a spare parts distributor. Besides several additional tables (brands, models, countries, etc.), the main subject are spare parts themselves. My question is what would be the proper database structure for spare parts. The matter is that some characteristics are common between all spare parts (id, article, price, brand, compatibility or car model, etc.) while some other are specific for a category. For example, for a leaf spring, the number of plates is important, and for a petrol tank it is the volume in litres. I can see three options with different pro and contra: One table for all spare parts. The table has all fields and all categories, but many of them are empty. Multi-table inheritance. There is one common model "Part" and many models inherited from it, one table for each category (PetrolTank, Radiator, etc.). This is most logical, but the number of tables can potentially be great (~ no. of categories). The great number of models in one application is not recommended (for example by the nice book "Two scoops of Django"). Proxy models. All parts are kept in one table, which has all fields, many of them inevitably empty. … -
Issue whith testing django view that execute asynchrnous task (celery): unexpected tests results
I try to implement tests in Django (DJango/Docker/django-celery/PostgreSQL) but have 2 issues with tests results when view execute celery asynchronous task. The upload_file ajax view works fine 'in live'. But in tests, I face 2 issues I can not figure out: self.assertEqual(1, RCountry.objects.count()) failed whereas self.assertEqual(1, ListRandomization.objects.count()) succeed. self.assertEqual(1, ListRandomization.objects.count()) succeed even if file_upload file contain more than one record: if file contain 5 rows with differents ran_ide (FK), should create 5 records in Randomization model and self.assertEqual(1, ListRandomization.objects.count()) should failed If self.assertEqual(1, ListRandomization.objects.count()) succeed that mean that task succeed and as upadte_or_create of the 2 models are in the same atomic transaction, success of one should imply success of the other. When I look celery logs container, logs confirm task succeed. #tests.py def test_upload_file_ajax_post_valid(self): ... with tempfile.NamedTemporaryFile(mode='w+', suffix='.csv', delete=False) as temp_file: csv_writer = csv.writer(temp_file) ... with open(temp_file.name, 'rb') as file_upload: response = self.client.post( reverse('randomization_settings:upload_file'), data={'file': file_upload}, HTTP_X_REQUESTED_WITH='XMLHttpRequest', ) # tests self.assertEqual(response.status_code, 200) self.assertEqual(1, RCountry.objects.count()) self.assertEqual(1, ListRandomization.objects.count()) os.remove(temp_file.name) views.py def upload_file(request): if request.headers.get('x-requested-with') == 'XMLHttpRequest' and request.method == "POST": form = FileUploadForm(request.POST, request.FILES) if form.is_valid(): ... # Update of Country (adm_pay) Randomization (tbl_ran) task = upload_list.delay(request.user.username) # asynchronous task ... return JsonResponse({"response": "success"}, status=200) else: return JsonResponse({"response": "form_invalid"}, status=200) else: … -
How to deploy Django app with nginx on non-root url?
I have some boxed solutions written on Django inside with docker-compose. I want to deploy it on the same server and specify different root url. But if I do it Django can't find static files, because it requests this files from root url, instead of specified url. How can I say to Django that root is another url? I was trying different examples for deploy Django with Nginx and nothing works. -

Updating html for specific model instance Django
I have a Django template that generates a HTML 'card-like' element for each model instance. Each instance (ie 'post') have a button, when on click, I would like to update a value within that SAME instance. I have been able to do this within the database, but am struggling with updating the HTML to match. Currently, my solution is updating ALL instances/posts. However, I only want to update it on the instance that had the button click. Does this make sense? Let me know if it doesn't. I will attach my code below along with an image demonstration. I did try passing through the event ID and making sure they align up for both the button and paragraph tag, but this seemed to not work. JS: function signUp(user, event, btn, eventID) { var csrftoken = Cookies.get("csrftoken"); var user_id = user var event_id = event attendance_count = document.querySelectorAll("#attendance"); if (btn.classList.contains("event-btn")){ request_info = "register"; } else if (btn.classList.contains("signUpBtnActive")){ request_info = "unregister"; } $.ajax({ type: "POST", url: "/event/update-attendance/", data: { user_id: user_id, event_id: event_id, request_info: request_info, "csrfmiddlewaretoken": csrftoken }, }).done(function(response){ if (attendance_count){ attendance_count.forEach(element => { event_id = element.getAttribute("event-instance"); if (event_id == eventID){ element.innerHTML = response; } }) } }); } My view: def … -

My project Repository looks like this: RECIPE-APP/ |-include/ |-Lib/ |-Scripts/ |-src/ |-media/recipes/ |-recipe_app/ |-settings.py |-wsgi.py |-recipes/ |-.env |-data.json |-db.sqlite3 |-manage.py |-.gitatributes |-.gitignore |-Procfile |-pyvenv.cfg |-requirements.txt I have a .env set up containing all keys for the DATABASES, in which case I copied all the required keys to heroku config vars. I reviewed the Procfile and it should be ok. Procfile: web: gunicorn src.recipe_app.wsgi --log-file - settings.py: """ Django settings for recipe_app project.
