Failing hstore tests Django
I am having a problem when I get the value from a hstore field. The situation is something like this: model: class Model(models.Model): hstoreField = HStoreField() test cases: def test_case_1(self): new_model = Model.objects.create( hstoreField = { 'key1': 'value1', 'key2': 'value2' } ) self.assertEqual(new_model.subscription['key1'], 'value1') self.assertEqual(new_model.subscription['key2'], 'value2') def test_case_2(self): Model.objects.create( hstoreField = { 'key1': 'value1', 'key2': 'value2' } ) new_model = Model.objects.get( id = 1 ) // assume it works self.assertEqual(new_model.hstoreField['key1'], 'value1') self.assertEqual(new_model.hstoreField['key2'], 'value2') When I run those test cases, the first one passes, but the second one fails and the error thrown is: TypeError: string indices must be integers. Checking the value of hstoreField is a string and it should be a dict. The error only happens in tests, in real code both cases work. Can you help me guys? -
How to make public chat using Django Channels WITHOUT AuthMiddlewareStack?

Deleting objects with unique-together constraints on SQL Server
Consider the following Django ORM example: class A(models.Model): pass class B(models.Model): a = models.ForeignKey('A', on_delete=models.CASCADE, null=True) b_key = models.SomeOtherField(doesnt_really_matter=True) class Meta: unique_together = (('a', 'b_key'),) Now let's say I delete an instance of A that's linked to an instance of B. Normally, this is no big deal: Django can delete the A object, setting B.a = NULL, then delete B after the fact. This is usually fine because most databases don't consider NULL values in unique constraints, so even if you have b1 = B(a=a1, b_key='non-unique') and b2 = B(a=a2, b_key='non-unique'), and you delete both a1 and a2, that's not a problem because (NULL, 'non-unique') != (NULL, 'non-unique') because NULL != NULL. However, that's not the case with SQL Server. SQL Server brilliantly defines NULL == NULL, which breaks this logic. The workaround, if you're writing raw SQL, is to use WHERE key IS NOT NULL when defining the unique constraint, but this is generated for me by Django. While I can manually create the RunSQL migrations that I'd need to drop all the original unique constraints and add the new filtered ones, it's definitely a shortcoming of the ORM or driver (I'm using pyodbc + django-pyodbc-azure). Is there some … -
Download link in template, when you have a model object with a filefield
Is it possible to make a download link in a html template, when you have a model object available, like this? models.py class Barcard(models.Model): name = models.CharField(max_length=30) drinks = models.ManyToManyField(Drink) barcardFile = models.FileField(blank=True, upload_to='barcard') mixingFile = models.FileField(blank=True, upload_to='mixing') views.py def download(request, barcard_id): if request.method == 'GET': barcard = get_object_or_404(Barcard, pk=barcard_id) return render(request, 'drinks/download.html', {'barcard':barcard}) else: return HttpResponseRedirect('/drinks/') template/drinks/download.html {% extends "drinks/base.html" %} {% block fulltitle %}Drinks{% endblock %} {% block content %} <h1>{{ barcard.name }}</h1> <p> Download barkort her: <a href='{{ MEDIA_URL }}{{ barcard.barcardFile.relative_path }}'>{{barcard.name}} barkort</a> </p> <p> Download blandekort her: <a href='{{ MEDIA_URL }}{{ barcard.mixingFile.relative_path }}'>{{barcard.name}} blandekort</a></p> {% endblock %} Right now I don't get a file, when clicking the link.

Django ManyToMany field gives IntegrityError

But when I try to add quotation in Admin Panel, it gives me null value in column "item_id" violates not-null constraint I am new to Django. It would be great if someone can point what I am missing. -
Django: custom http header authentification
I want to create an authentication for my Django 1.11 project. A user will be authenticated if the request contains the header : X_USERNAME. I am working with generic views so I use LoginRequiredMixin to control access. I made this Custom authentication class: class CustomAuthentication: def authenticate(self, request): username = request.META.get('X_USERNAME') logging.warning(username) if not username: return None try: user = User.objects.get(username=username) except User.DoesNotExist: user = User(username=username) user.is_staff = False user.is_superuser = False if request.META.get('X_GROUPNAME') == 'administrator': user.is_staff = True user.is_superuser = True user.save() return user, None def get_user(self, user_id): try: return User.objects.get(pk=user_id) except User.DoesNotExist: return None I added it in my settings : AUTHENTICATION_BACKENDS = ['path.to.file.CustomAuthentication'] But I can't make it work. I am redirected to /accounts/login/?next= which doesn't exist. Thanks in advance! -
Django migration doesn't generate any SQL or affect any tables
I edited my models, and ran python manage.py makemigrations appname. This created a migration which looks something like this: class Migration(migrations.Migration): dependencies = [ ('appname', 'previous_migration'), ] operations = [ migrations.RemoveField( model_name='foo', name='bar', ), migrations.AddField( model_name='foo', name='baz', field=models.CharField(blank=True, default='', max_length=100), ) ] All good, so far. But when I run python manage.py migrate appname --database MY_DB, nothing happens to the appropriate tables. The migration gets written to django_migrations as if it went through, but the foo table is unaffected. When I run python manage.py sqlmigrate appname mymigration --database MY_DB, I get an essentially empty SQL script: BEGIN; -- -- Remove field bar from foo -- -- -- Add field baz to foo -- COMMIT; This is unfortunately all info I can provide, as I wasn't able to find any further clues as to this behavior. -
Django Serializer nests when overriding to_representation()
I have a serializer ReservationSerializer: Class ReservationSerializer(serializers.ModelSerializer): pax_leader = serializers.SerializerMethodField() class Meta: model = models.Reservation fields = ('id', 'booking', 'agency', 'comment', 'status', 'arrival_date', 'departure_date', 'confirmation', 'confirmation_date', 'euroamerica', 'user', 'timestamp', 'pax_leader', 'is_invoiced') depth = 0 def get_pax_leader(self, instance): try: pax_leader = models.ReservationPerson.objects.get(reservation=instance.id, is_primary=True) except: pax_leader = None if pax_leader: return pax_leader.name else: return None def to_representation(self, instance): representation = super().to_representation(instance) representation['agency'] = AgencySerializer(instance.agency).data return representation I don't know why I get the result nested with several levels of depth. If remove to_representation(), I get the result without nesting, but I need to add agency. I don't know how to manage this behavior. -
Django admin UserChangeForm with UUID field as primary key
I'm working on a Django app that will contain sensitive User data, so I'm taking a number of steps to anonymise User objects and their data. I created custom 'User' object that subclassses the AbstractBaseUser model like so: class User(AbstractBaseUser, PermissionsMixin): (...) id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) (...) It has the following linked ModelAdmin object: from django.contrib.auth.forms import UserChangeForm @admin.register(User) class UserAdmin(admin.ModelAdmin): form = UserChangeForm I'm using UUID fields for primary keys to ensure maximum anonymity, yet I would like to be able to reset User passwords in the Django Admin (like you can do with the default User object) However, when I open a User in the admin and press the link to change the password I get the following error message: User with ID "21362aca-6918-47ea-9b29-275350a89c54/password" doesn't exist. Perhaps it was deleted? The admin url is still expecting a url with the an integer as its pk value. So it seems that I have to override the admin url configuration in the ModelAdmin definition, but I was wondering if there was a simpler way to achieve the desired result - as I imagine that replacing the User.pk with an UUID field is a fairly regular occurrence and I image … -

django: how to model a game where actions could be known some time after they have been executed?
I want to write a Django App to track a real time game (that is, the players are required to do some tasks in real life as days pass). The main problem in design I'm experiencing is that the system could be informed of some action with a delay of some hours, and such actions could interfere with some other actions that were already registered on the website. Let's make an example: it is enough to know that every player has a money balance and if player A gets "killed" by player B, then player B "steals" all the money from player A. Such money can be used to buy some things that are helpful in the game. Suppose the following happends: (3 PM - Initial state) A has 5 money, B has 3 money (4 PM - Action) B "kills" A. This actions is inserted into the website at 6 PM (5 PM - Action) A buys a thing for 4 money. I would like that when we know what happened at 4 PM (B has killed A), the application should recompute the state from the initial one and then simply exclude A action at 5PM since at that … -
Django : Import javascript inside a template doesn't work
I'm facing a new problem with django. I'm developping a website (so I'm not in the production step) and I want to use javascript in my template. When I write my script directly on my template and link it to a button the script works. But when I want to import it from a .js file it doesn't works anymore. My static directory seems to work correctly, I can import css or even images from it. Here is my files : base.html : <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> {% load static %} <title>Title</title> <link rel="stylesheet" href="{% static 'webcalendar/css/bootstrap.css' %}"> <link rel="stylesheet" href="{% static 'webcalendar/css/style.css' %}"> {% block script %} {% endblock %} </head> <body> {% block content %} {% endblock %} </body> </html> fonction_test.html : where the script is directly written in the template {% extends 'webcalendar/base.html' %} {% block script %} <script type="text/javascript"> function printInConsole(){ console.log("PRINTING...") } </script> {% endblock %} {% block content %} <button onclick="printInConsole()" class="btn btn-warning">Print in console</button> {% endblock %} So the previous one is working.

How to mock a Django internal library using patch decorator
I'm mocking an internal library class (Server) of python that provides connection to HTTP JSON-RPC server. But when running the test the class is not mocking. The class is used calling a project class that is a wrapper for other class that effectively instantiates the Server class. I extract here the parts of the code that give sense for what I'm talking about. Unit test: @patch('jsonrpc_requests.jsonrpc.Server') def test_get_question_properties(self, mockServer): lime_survey = Questionnaires() # ... Class Questionnaires: class Questionnaires(ABCSearchEngine): """ Wrapper class for LimeSurvey API""" def get_question_properties(self, question_id, language): return super(Questionnaires, self).get_question_properties(question_id, language) Class Questionnaires calls the method get_question_properties from class ABCSearchEnginge(ABC).
