APITestCase. How to authenticate users outside of the test functions?
Background I used to authenticate users inside each test function Goal now I am trying to authenticate the user in the APITestCase class in order to use the same authentications in mutlable functions. Problem when I add the credentials in the class it seems not effecting the function? class TestTimeSheets(APITestCase): if (not User.objects.filter(username='newusername').exists()): user = User.objects.create( username='newusername', email='newusername@g.com', password='password', is_email_verified=True, is_role_verified=True, is_staff=True, is_superuser=True) else: user = User.objects.get(username='newusername') client = APIClient() lg_res = client.post('/users/login/', {'username': 'newusername', 'password': 'password'}, format='json') client.credentials( HTTP_AUTHORIZATION=f'Bearer {lg_res.data["access"]}') resp = client.get('/statistics/',) print('======================') print(resp.data) #🔴 this returns the correct data print('======================') def test_statstics(self): resp = self.client.get('/statistics/',) # self.assertEqual(create_res.status_code, status.HTTP_201_CREATED) print('======================') print(resp.data) #🔴 but this says you are not authenticated. print('======================') -
GeoDjango: How to create a circle anywhere on earth based on point and radius?
I have a similar question to this one. Using geodjango, I am wanting to draw a circle on a map with a certain radius in km. However, the suggested solution a) does not use km but instead degrees, and b) becomes an oval further north or south. Here is what I do: from django.contrib.gis import geos lat = 49.17 lng = -123.96 center = geos.Point(lng, lat) radius = 0.01 circle = center.buffer(radius) # And I then use folium to show a map on-screen: map = folium.Map( location=[lat,lng], zoom_start=14, scrollWheelZoom=False, tiles=STREET_TILES, attr="Mapbox", ) The result is this: How can I a) draw a circle that is always 3 km in radius, independent from the position on the globe, and b) ensure this is a circle and not an oval at all latitudes? -

Search through hashids if it contains specific value Django-hashids
I am using django-hashids for my IDs and I have to have a search function that looks up the encoded IDs. Right now, this is how it works search_string = request.query_params.get(self.search_param, "") result = view.hashids.decode(search_string) But this one requires the whole hashid to return a specific value. If the hashid is for example qwerty123 I have to input the whole string so that I'll get the right item. Is there any way that even if I just input qwerty, it will return the IDs that contain the inputted string? -

Modify field data from a different app on Django

SQLAlchemy optional ForeignKey
In SQLAlchemy.orm I have the following class: class Table(Base): __tablename__ = 'table' id = Column(Integer, primary_key=True) src = Column(Integer, ForeignKey('other.id')) dst = Column(Integer, ForeignKey('other.id')) source = relationship("Other", foreign_keys=[src]) destination = relationship("Other", foreign_keys=[dst]) I want to make the src and source optional which means those records could be empty in the table. In Django's ORM, I used to make a model field optional by using blank=True and null=True like: src = models.ForeignKey(Other, blank=True, null=True) There is a default parameter for each column in SQLAlchemy as well. I tried: src = Column(Integer, ForeignKey('other.id'), default=None) But it doesn't work.
