Raw SQL Query using a list parameter fails
I have the following code: products = Product.objects.raw( 'SELECT DISTINCT ON(I.product_id) P.id, P.name, P.desc, C.name AS ram, I.image ' 'FROM products_product AS P ' 'LEFT JOIN categories AS RPC ON P.id = RPC.product_id ' 'LEFT JOIN company AS CP ON P.company_id = CP.id ' 'LEFT JOIN category AS C ON RPC.category_id = C.id ' 'LEFT JOIN image AS I ON I.product_id = P.id ' 'WHERE P.id IN %s', list ) I receive the following error: not all arguments converted during string formatting Instead of list I tried to use [2,4] or ['2', '4'] , same error. If I use without a parameter is working. I use PostgreSQL. -
Get correct results from the database in Django
I have three Django models as follows: class NewFeature(models.Model): application = models.CharField(max_length=50) name = models.CharField(max_length=250) start = models.DateTimeField(null=True, blank=True) stop = models.DateTimeField(null=True, blank=True) groups = models.ManyToManyField(to=Group) class NewFeatureDetails(models.Model): new_feature = models.ForeignKey(to=NewFeature) culture = models.CharField(max_length=3, blank=False, default='en') text = models.TextField() picture = models.ImageField(upload_to=settings.MEDIA_ROOT, blank=False, null=False) class NewFeatureRead(models.Model): new_feature = models.ForeignKey(to=NewFeature) user = models.ForeignKey(to=User) timeStamp = models.DateTimeField(auto_now=True) Thus start and stop in NewFeature model could be empty but they also could have values. I want all records from NewFeatureDetails model for which user_id doesn't exist in NewFeatureRead where: current_time is between start and stop from NewFeature if they exist or if only start exists I want only results where start < current_time and also if only stop exists I want only results where current_time < stop What I tried is something like this: def getNewFeatures(request): current_user_id = request.user.id new_features = NewFeatureDetails.objects.exclude(new_feature__newfeatureread__user_id=current_user_id) if new_features: features = [] for feature in new_features: start = feature.new_feature.start stop = feature.new_feature.stop current_time = datetime.datetime.now() // I'm stuck here return new_features Is there a better way? Can it somehow be done in the query? If not, how could I do it on this way, as I tried? -
Django: Queryset object filter, against another object's time range
I have 3 models, run, sensor_parameter and data. There are other ForeignKey relationships in between those, but run has no direct ForeignKey to either sensor_parameter or data. A run has a start_time and an end_time, and is related to a chamber. class Run(models.Model): start_time = models.DateTimeField(db_index=True) end_time = models.DateTimeField(db_index=True) chamber = models.ForeignKey(Chamber, on_delete=models.CASCADE) A chamber has a relation to a sensor and a sensor has a set of sensor_parameter(s) class SensorParameter(models.Model): sensor = models.ForeignKey(Sensor) parameter = models.ForeignKey(Parameter) And a data point finally "belongs" to a sensor_parameter: class Data(models.Model): time = models.DateTimeField(db_index=True) sensor_parameter = models.ForeignKey(SensorParameter, on_delete=models.CASCADE) parameter_value = models.FloatField() I need to filter a list of sensor_parameter(s), that belong to a run, but my only link between them is a time value. Since data has a time stamp, and a run has start_time and end_time, I thought I could filter a list of data.sensor_parameter in a time period range. I'm not sure how to build that quieryset filter. I have imported datetime, and have access to django_filter. This is what I have so far in my views.py import datetime import django_filters def get(self, request): # Get a list of run objects, that are passed through the request run_ids = request.GET.getlist('id') runs … -

Creating a pre-authenticated session in a django test
this is my first ever post as I have found hundreds of answers before by searching. So, thank you and please bear with me. I am working through the excellent book Test Driven Development with Python and trying to apply it to my project. There is test code for skipping the login process by pre-authenciating a session: from django.conf import settings from django.contrib.auth import BACKEND_SESSION_KEY, SESSION_KEY, get_user_model from django.contrib.sessions.backends.db import SessionStore from .base import FunctionalTest User = get_user_model() class MyListsTest(FunctionalTest): def create_pre_authenticated_session(self, email): user = User.objects.create(email=email) session = SessionStore() session[SESSION_KEY] = user.pk session[BACKEND_SESSION_KEY] = settings.AUTHENTICATION_BACKENDS[0] session.save() ## to set a cookie we need to first visit the domain. ## 404 pages load the quickest! self.browser.get(self.live_server_url + "/404_no_such_url/") self.browser.add_cookie(dict( name=settings.SESSION_COOKIE_NAME, value=session.session_key, path='/', )) This is called in a test like: def test_logged_in_users_can_do_something(self): email = 'edith@example.com' self.browser.get(self.live_server_url) self.wait_to_be_logged_out(email) # Edith is a logged-in user self.create_pre_authenticated_session(email) print(self.browser.get_cookies()) self.browser.get(self.live_server_url) print(self.browser.get_cookies()) self.wait_to_be_logged_in(email) # code to test that this user can do something... self.browser = selenium.webdriver.Firefox() is defined in the FunctionalTest base class setUp(). This works fine for the User model used in the book which is derived from models.Model. The problem is that when I customise the user model further and inherit from AbstractUser or … -
Should I avoid using models in django migrations?
I am working on an existing Django project that contains migration code like: someFluffyModel.objects.all().delete() or someModel = SomeModel(....) someModel.save() Now wherever there is such code and newer migrations change the schema that reflect the current version of the model, there is an issue in applying migrations from scratch. As I understand the reason is that the model used in the migration doesn't reflect the model used in the migration at that point in time. As I have found fixtures can help in loading data but how about deletion? Is the preferred way to manually delete data from the database? -

django call a view with optional argument
I wrote a middleware that prevents from users in certain group to access a view, If a user without permission tries to access the page it should redirect him to a login with a message (saying he has no permissions). I thought to do it like that: have a login view: def login_view(request, permission=None): and in the middleware: class ManagerRequiredMiddleware(MiddlewareMixin): def process_request(self, request): assert hasattr(request, 'user') if not request.user.groups.filter(name='Manager').exists(): path = request.path_info.lstrip('/') if not any(m.match(path) for m in EXEMPT_URLS) and not any(m.match(path) for m in MANAGER_URLS): print('no manager') next = request.path_info #return redirect('/login/?next=%s' % next, permission=True) #return HttpResponseRedirect(reverse('login', kwargs={'permission': True})) return redirect('/login/?next=%s' % next) as you can see I tried multiple things. I want to keep the where he tried to access (to redirect him after login), but also want to call login_view with the permission flag on so I can display the right message. I don't want this argument to be visible in the URL. Thanks. -

Django query- 'not equal to' filter
I am writing a Django query to filter a list of teams which the user is a part of.

Below that I then want to print a list of teams where the UserTeams UserID = request.user,(userteamquery) but the problem I have is that some teams are appearing in both query results, so are printed in both lists. Is there a 'not equal' query i can use where it will exclude all UserTeams in the userteamquery where the teamID is a result of teamquery? so teamID=teamquery @login_required def teamsview(request): teamquery = Team.objects.filter(owner=request.user) userteamquery = UserTeams.objects.filter(userID=request.user) return render(request, 'teammanager/teams.html', { "teams": teamquery, "userteams": userteamquery}) -

Celery task .get() not working
I will really appreciate help with this! This is my first attempt at using Celery with Django in Docker containers and I can't get passed this problem after many hours of reading and experimenting. PROBLEM I can import the task from polls.task and run it using .delay() as follows: python manage.py shell from polls.tasks import add task = add.delay(4,4) When I run this, I can see a message through the rabbitmq container. If I execute task.id, i can get the task id. HOWEVER, if I run task.get(), the program just hangs. I see no action on any of the containers and I get no result. I have also noticed that, when I run dc-up and start all the containers, I get the following output on the worker container, which seems correct: worker | -------------- default@5d0902ad9e2a v4.1.0 (latentcall) worker | ---- **** ----- worker | --- * *** * -- Linux-4.9.87-linuxkit-aufs-x86_64-with-debian-8.10 2018-03-30 09:45:01 worker | -- * - **** --- worker | - ** ---------- [config] worker | - ** ---------- .> app: composeexample:0x7f2f3255e320 worker | - ** ---------- .> transport: amqp://admin:**@rabbitmq:5672// worker | - ** ---------- .> results: redis://redis:6379/0 worker | - *** --- * --- .> concurrency: 2 (prefork) …
