Django static precompiler doesn't work in production mode
I installed django-static-precompiler completely according to the documentation to compile my scss-files and it works brilliantly... until I set DEBUG from True to False. From that moment on, the staticfiles cannot be found anymore: File "/usr/local/lib/python3.6/site-packages/django/contrib/staticfiles/storage.py", line 422, in stored_name raise ValueError("Missing staticfiles manifest entry for '%s'" % clean_name) ValueError: Missing staticfiles manifest entry for 'COMPILED/css/porcupine.css' In my html file, I compile and load the .scss as follows: <link rel="stylesheet" href="{% static "css/porcupine.scss"|compile %}"/> This file is indeed being created, but only when Debug=False is not picked up by the file system, or so it seems. Surprisingly, the file is exactly where it is supposed to be and the compiled file can be inspected in the browser at: http://localhost:8000/static/COMPILED/css/porcupine.css So the question is: what's going on? How to make Django find the compiled files in production mode (DEBUG=False)? I happily include more settings upon request, but Django is a bit convoluted in its many settings in different files, and I would like to keep this post simple. -
Can't start worker, No module named 'celery
I try to include tasks in my webapplication but i can't start the celery work. My project structure is the following: website/website --> init.py, settings.py, urls.py, wsgi.py website/index --> init.py, celery_app.py, tasks.py Index is my startpage where i want to run the tasks. index/celery_app.py has the following code: from __future__ import absolute_import, unicode_literals from celery import Celery app = Celery('index', broker='amqp://localhost//', backend='amqp://', include=['index.tasks']) # Optional configuration, see the application user guide. app.conf.update( result_expires=3600, ) if __name__ == '__main__': app.start() index/tasks.py: from __future__ import absolute_import from .celery_app import app @app.task def test_func(): print("Test Background Task") When i want to start the worker with celery -A index worker --loglevel=info I get the following error: ModuleNotFoundError: No module named 'celery'.

Django How to check if entry exists in database?
I have the following model in my application: class Device(models.Model): class Meta: verbose_name_plural = "devices" imei = models.CharField(max_length=15, unique=True) last_update = models.DateTimeField() rule = models.CharField(max_length=20) @classmethod def create(cls, imei, last_update, rule): device = cls(imei = imei, last_update = last_update, rule = rule) return device def __str__(self): return self.imei Now, after I do an update I want to check if the device is already stored in my database. So I used this code: if Device.objects.filter(imei="123456789").exists(): return True else: return False But for some reason when I run it, it doesn't work and I keep getting 500 error. What am I doing wrong here? -
Migration of Django field with default value 0 to PostgreSQL database
I want to update default column value but it seems like default value on columns is is only on the ORM layer, and is not actually setting a default value in the DB and returns error django.db.utils.OperationalError: cannot ALTER TABLE "bps_registration_application" because it has pending trigger events. Is it possible to update default columnn value to 0 in postgress migrations by updating in django model? This is models.py. class Application(models.Model): registration_date = models.CharField(max_length=15) building_use = models.ForeignKey(to=system_settings.models.BuildingUse) building_category = models.CharField(max_length=30) building_structure_category = models.ForeignKey(to=system_settings.models.BuildingStructureCategory) building_length_ft = models.IntegerField(blank=True, default=0) building_breadth_ft = models.IntegerField(blank=True, default=0) building_height_ft = models.IntegerField(blank=True, default=0) building_length_in = models.IntegerField(blank=True, default=0) building_breadth_in = models.IntegerField(blank=True, default=0) building_height_in = models.IntegerField(blank=True, default=0) building_storey = models.IntegerField(blank=True, default=0) building_area = models.DecimalField(max_digits=6, decimal_places=2) reg = models.ForeignKey(NewRegistration) -
Pytest PropertyMock as return_value for MagicMock does not get invoked
I am trying to mock the return_value for a MagicMock instance as a PropertyMock but it appears to be returning the PropertyMock object without invoking it i.e. does not return the actual value. class MySerializer(serializers.ModelSerializer): class Meta: model = MyModel # ... fields = ( "my_field" ) my_field = serializers.SerializerMethodField() def get_my_field(self, instance): other_models = instance.group.filter() if other_models: # returns <class 'unittest.mock.PropertyMock'> instead of an actual value print(type(other_models.get().my_property)) # throws error since it isn't receiving a string return ujson.loads(other_models.get().my_property) return {} # test case def test_hello(mocker): expected_value = ujson.dumps({'hello': 2}) instance_mock = mocker.MagicMock() other_model_mock = mocker.MagicMock() other_model_mock.get().my_property = mocker.PropertyMock(return_value=expected_value) instance_mock.group.filter.return_value = other_model_mock serializer = MySerializer() observed_value = serializer.get_my_field(instance_mock) assert expected_value == observed_value -
Django only allowing users into their own profile for multiple pages
I have this URL "private/profile/" and I wrote something like this to keep any user except the profile owner out of that page if int(pk) != profile: return HttpResponse("ERROR:...") else: return render(...) The problem is that I have multiple urls like "private/profile//editProfile", and I need to write the code above for every single URL. Is there a better practice for this? -
Using PostgreSQL aggregate expressions in Django
As of PostgreSQL 9.0+, using aggregate expressions is supported. For example, you are able to use ORDER BY to sort rows before calling on to the PostGIS function ST_MakeLine as below: SELECT ST_MakeLine(position ORDER BY timestamp)::bytea AS line FROM recorded_positions WHERE dataset_id = 98 ORDER BY timestamp ASC What I have in my application is the following in an attempt to do this but clearly this is not the use case for order_by(): queryset = queryset.order_by('timestamp') \ .annotate(line=Func('position', function='ST_MakeLine')) \ .values('line') Of course this produces the following wrong SQL for what I want (and invalid due to use of order_by on a non aggregate column): SELECT ST_MakeLine(position)::bytea AS line FROM recorded_positions WHERE dataset_id = 98 ORDER BY timestamp ASC Is this possible at all with Django or will I have to do something else (raw query, subquery, etc) to accomplish the same result? -
Some issues with UUID while migrating from SQLite to Postgresql in Django 2.0
I am trying to migrate my Django 2.0.4 project from SQLite to PostgreSQL 10 following the steps described here, but I am having differents problems. During the project I changed some Integer fields to UUID4 fields. I managed to run python manage.py migrate --run-syncdb manually editing auto_increment migration file making changes of this type (see id field): From class Migration(migrations.Migration): dependencies = [ ('dumps', '0011_auto_20180608_1714'), ] operations = [ migrations.CreateModel( name='Report', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('data', models.DateTimeField(auto_now_add=True, verbose_name='Date')), ], ), ... ... ...

Next, I commented all auto_increment files in which there was an AlterTable on uuid fields, but when I run python manage.py loaddata datadump.json I obtain the following error: django.db.utils.ProgrammingError: Problem installing fixture 'C:\Users\djangoproject\datadump.json': Could not load myApp.Reservation(pk=10d00b08-bf35-469f-b53f-ec28f8b6ecb3): ERROR: column "reservation_id" is integer type but the expression is uuid type LINE 1: UPDATE "myApp_reservation" SET "reservation_id" = '066cff3c-4b... -
How to implement pagination in django?
I found a resource where it has code like this: from django.contrib.auth.models import User from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger def index(request): user_list = User.objects.all() page = request.GET.get('page', 1) paginator = Paginator(user_list, 10) try: users = paginator.page(page) except PageNotAnInteger: users = paginator.page(1) except EmptyPage: users = paginator.page(paginator.num_pages) return render(request, 'core/user_list.html', { 'users': users }) I have a code like this: def product_list(request, category_slug=None): category = None categories = Category.objects.all().order_by("-rating") #paginator = Paginator(categories, 10) products = Product.objects.all().order_by("-number") users = User.objects.exclude(id=request.user.id) query = request.GET.get('q') if query=='': return HttpResponseRedirect('/') if query: categories = Category.objects.filter(Q(slug__icontains=query)| Q(url__icontains=query)).order_by("-rating") products = Product.objects.filter(Q(slug__icontains=query) | Q(name__icontains=query) | Q(description__icontains=query)).order_by("number") if category_slug: category = get_object_or_404(Category, slug=category_slug) products = Product.objects.filter(category=category) categories_counter = products.annotate(Count('id')) categories_count = len(categories_counter) #contacts = paginator.get_page(query) context = { 'category': category, 'categories': categories, 'products': products, 'categories_count':categories_count, 'query':query, 'users':users, #'contacts':contacts, } return render(request, 'shop/product/list.html', context) I have retrieved objects from two models, Category, and Product. How do I implement the pagination code in this view? I also don't get the idea of the page= request.GET.get('page',1) because i have query = request.GET.get('q') in my code. Is page built-in function? -

How do I manage a rapidly growing postgres table in Django?
I have a website that is used to show live data from different machines in a crushing facility. Right now the "Sensor Data" obtained from all the machines in one facility is stored in a "sensordata" table and this data is used by the user to make reports for a time period(upto last three months). The site has been running for 3 months now and the sensor data table is already at 113 million rows. My company is planning to add even more facilities( this will multiply then number of machines). What's a good solution to store this large an amount of data?(That's also future safe for say 100's of facilities) -
How can I add a small snippet of code that uses request and runs when someone accesses the django admin page?
How can I add a small snippet of code that runs when someone accesses the admin page. I am trying to get the IP address of users that use the admin and make changes to the database. I can use django signals to see when changes are made, but I need to access django request in order to gain access to a user's IP address. I thought a simple way would be to just add a snippet of code in the the admin views where I would request the IP address and save it in a variable. I looked into overriding the django admin views, but everything I found seemed to be correlated with creating querysets and returning http request in some way, which is not what I want (I don't believe.) -
Django url parameter appended with "/None"

Why does Ajax refresh page on mobile devices after submitting form via POST method?
I am trying form submission on my Django website. Ajax works fine for form submissions on Desktop and doesn't refresh page on submission, whereas when using on mobile devices the POST data is submitted successfully but the page refreshes after the request.
