Integrating django-image-cropping to Azure Blob Storage
I am trying to move my media files to an azure file storage, however I'm finding an issue when trying to generate the cropped file as it is not being saved in the azure file storage. Files in model file is as per the below: class ImageShow (models.Model): title = models.CharField(max_length=50) image = models.ImageField(upload_to='homepage/images/') active = models.BooleanField(default=False) cropping = ImageRatioField('image', '1200x400') In template I'm calling it as per the below: <img class="d-block w-100" src="{% cropped_thumbnail images "cropping" scale=1.0 %}"> and the below are the settings specified in setting.py from easy_thumbnails.conf import Settings as thumbnail_settings THUMBNAIL_PROCESSORS = ( 'image_cropping.thumbnail_processors.crop_corners', ) + thumbnail_settings.THUMBNAIL_PROCESSORS As for Azure File Storage I have the below code: In settings.py AZURE_ACCOUNT_NAME = '' AZURE_ACCOUNT_KEY = '' AZURE_CUSTOM_DOMAIN = f'' AZURE_LOCATION = '' AZURE_CONTAINER = '' MEDIA_URL = f'https://{AZURE_CUSTOM_DOMAIN}/{AZURE_LOCATION}/' DEFAULT_FILE_STORAGE = 'storages.backends.azure_storage.AzureStorage' In custom_azure.py from storages.backends.azure_storage import AzureStorage from django.conf import settings class AzureMediaStorage(AzureStorage): location = settings.AZURE_LOCATION file_overwrite = False And in Urls I have the below code: urlpatterns+= static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Any Ideas please on how to make it work with Azure blob storage.

Django {% trans %} not translating new changes
I am trying to run a web-app locally (forked from here ) . I am using the {% trans %} tag to mark strings to be translated. The original piece of code was <h3> Personal data</h3>. However , when I change it to <h3>{% trans "Personal data" %}</h3> , the "Personal data" does not get translated , even though the original text (from the forked repository) in the following line gets translated . The following screenshot highlights the issue : When I make any changes to the text between <html> tags, it gets reflected in my local instance. But when I make changes to strings marked with {% trans %} , it does not get translated in my local instance (even though the rest of the original text gets translated) . Note : Changes made to text without {% trans %} tag are getting reflected in my local instance. The app is run using docker-compose up Why does the {% trans %} tag not work on new changes ? -

I connected to the project on host and when i type the collect static command I have this error: django.core.exceptions.ImproperlyConfigured: You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path. this is the admin panel: and this is my project settings.py: LANGUAGE_CODE = 'en-us' TIME_ZONE = 'Asia/Tehran' USE_I18N = True USE_L10N = True USE_TZ = True # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/3.0/howto/static-files/ STATIC_URL = '/static/' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') # ckeditor CKEDITOR_BASEPATH = "/static/ckeditor/ckeditor/" CKEDITOR_UPLOAD_PATH = "uploads/" -
Does Django Development Web Server Cache Redirects?
I have a Django view that I redirect a user to after they login: # settings.py LOGIN_REDIRECT_URL = 'login-redirect' # account/urls.py urlpatterns = [ path('', include('django.contrib.auth.urls')), ... ] # home/views.py from account.models import Member def login_redirect(request): """ Redirect member to appropriate page when they log in. """ member = Member.objects.get(user__id__exact=request.user.id) if member.has_profile: return redirect('homepage', member_id=member.id) else: return redirect('profile-create', member_id=member.id) If I start Django's development server and execute this code when the condition member.has_profile = True, Django redirects me to the homepage view as expected. But if I then go into the database and set has_profile to False, restart the web server, and execute code again, my website acts as if the code isn't executed. Instead, I'm sent immediately to the homepage view again. I can see this by looking at the terminal console: [19/Feb/2021 ...] "GET /account/login/ HTTP/1.0" 200 4268 # I'm using Django's default login method [19/Feb/2021 ...] "POST /account/login HTTP/1.0" 302 0 [19/Feb/2021 ...] "GET /home/login_redirect/ HTTP/1.0" 200 4599 This happens even though I am restarting the server and clearing my browser's cache. In fact, I can edit the login_redirect function so that it only contains a single line pass and I'm still sent to the homepage after … -

Django Rest Framework not accepting JWT Authentication Token
I am using the Django Restful API Framework together with Simple JWT and have successfully created a URL for receiving and refreshing a user token. In order to try out the authentication using the token, I have created a view that simply lists all the posts inside the database. I have then assigned the IsAuthenticated class to the view. As expected, I get an error message saying that the authentication credentials were not provided. I then went ahead and made a simple GET request using Postman, with the authentication token provided in the "Authorization" tab. The type was set to "Bear Token". Unfortunately, I still get the message "Authentication credentials were not provided." with a 403 Forbidden code. I have also tried to provide the token in the Headers, as well as make CURL requests, everything to no avail. My view looks like this: class PostListView(generics.ListAPIView): permission_classes = (IsAuthenticated,) queryset = Post.objects.filter() This is the serializer: class PostListSerializer(serializers.ModelSerializer): class Meta: model = Post fields = ('__all__') The settings.py of the Django project: REST_FRAMEWORK = { 'DEFAULT_FILTER_BACKENDS': ['django_filters.rest_framework.DjangoFilterBackend'], 'DEFAULT_PERMISSION_CLASSES': ['rest_framework.permissions.AllowAny'], 'DEFAULT_AUTHENTICATION_CLASSES:': ('rest_framework_simplejwt.authentication.JWTAuthentication',) } CORS_ALLOW_ALL_ORIGINS = True # For testing purposes I have followed several different tutorials online, read through numerous posts … -
Write JSON to a file in pretty print format in Django
I need to create some json files for exporting data from a Django system to Google Big Query. The problem is that Google BQ impose some characteristics in the json file, for example, that each object must be in a different line. json.dumps writes a stringify version of the json, so it is not useful for me. Django serializes writes better json, but it put all in one line. All the information I found about pretty printing is about json.dumps, that I cannot use. I will like to know if anyone knows a way to create a json file in the format required by Big Query -

Django postgis point is in polygon or on boundary

Django-Graphene - Relation to an object of the same type
I have defined a database model in which a task object has a relationship to the same task object. class Task(models.Model): id = models.AutoField(primary_key=True) status_id = models.ForeignKey(Status, null=True, on_delete=models.SET_NULL) parent_id = models.ForeignKey('self', null=True, on_delete=models.SET_NULL) name = models.CharField(max_length=128) description = models.CharField(max_length=256) entry = models.IntegerField() In the Graphql API I made it possible to get a task object for myself. I would like to achieve the possibility of retrieving the entire object tree of the same type by calling a graphql query with one call to the object type task. Is it possible? class TaskType(graphene.ObjectType): id = graphene.NonNull(graphene.Int) parent_id = graphene.Field(graphene.Int) name = graphene.NonNull(graphene.String) description = graphene.NonNull(graphene.String) entry = graphene.NonNull(graphene.Int) parent = graphene.List(lambda: TaskType) @staticmethod def resolve_parent(task, _info): return Task.objects.filter(parent_id=task.id) I know I can return such a tree in JSONString type, but I'm looking for a different solution. -
Django query, finding the maximum object

I have a query like this: MyModel.objects.filter(...).aggregate(max_value=Max('value')) and this does, indeed, return a (dictionary) with key 'max_value' and value that maximum value. But what I want is the object that has that maximum value. -

Automatically attach VS Code configuration to container
I'm using a VS code config to attach to a running container so I can run my tests inside the container. ptvsd is used for this. launch.json has the following config: { "version": "0.2.0", "configurations": [ { "name": "Run Django", "type": "python", "request": "attach", "pathMappings": [ { "localRoot": "${workspaceFolder}/src", "remoteRoot": "/app" } ], "port": 3000, "host": "127.0.0.1", } ] }< ´´´ I also have a volume mapping in my `docker-compose.yml` so my updates are reflected directly in the container: volumes: - ./src:/app The issue is ... when I make a change VS code unattaches itself and I have to go into debug to restart it. Is there any way to configure VS code so that if an attach fails it will retry it after a few seconds for, say up to a minute or so? This would allow the StatReloader to complete and give it something to attach to. -
