Django: Leaflet map does not render when adding new item in admin inline
I am using the django-leaflet package to display the maps in the admin. I have a model that I am inserting as TabularInline, where one of the fields is a PointField. model.py class Occurrence(models.Model): name = models.CharField(max_length=254) location = models.PointField(null=True, blank=True) # ....... admin.py class OccurrencesInline(LeafletGeoAdminMixin): model = Occurrence fields = ('name', 'location') show_change_link = True extra = 1 formset = AtLeastOneFormSet The map appears correctly in the extra rows that appear initially. However, when I add a new item, instead of the map, a text box appears. Any idea why this is happening and how to fix it? -

No UID when using Django admin page to create objects
So I have created a custom User model and a common model as base for all other models that adds a created_by field.

Is there a way to improve the health of EB environment?
I tried to create a new application with a new environment in AWS Elastic Beanstalk and the it ran ok to begin with. But once I uploaded and deployed (successfully) my Django app on it, it degraded in health to severe. The error is : Environment health has transitioned from Degraded to Severe. 100.0 % of the requests are failing with HTTP 5xx. My application runs fine on my machine. I have set up the requirements and remove pywin32 and pypiwin32 from it coz this is a linux instance on AWS. Also here is my django.config file in .ebextensions: option_settings: aws:elasticbeanstalk:container:python: WSGIPath: employee_records.wsgi:application I have added all changes (including the virtual env) to staging area in github. I have chosen the application load balancing (default 2). So please help as to why this error occurs. -
Creating custom fields with django-filters
I have a model as shown below. The model has the attribute type as a foreign key. class YachtGeneralInfo(models.Model): type = models.ForeignKey( YachtTypes, related_name="yachts_in_type", on_delete=models.PROTECT, blank=False, null=False, ) .... .... I wrote a view class like this - class YachtGeneralInfoView(ListAPIView): pagination_class = PageNumberPagination serializer_class = YachtGeneralInfoSerializer filter_backends = [OrderingFilter, SearchFilter, DjangoFilterBackend] filterset_fields = [ "status", "is_professional", "chartered_with__id", "harbour__id", "harbour__city__id", "model__id", ] search_fields = ["name", "company_name", "website", "owner__name"] I would like to add another filter for field type. However, I want to provide multiple values for this query parameter like [1,2,3]. If I do that directly with queryset then it would be like this - queryset = YachtGeneralInfo.objects.filter(type__in=[1,2,3]) Is there a way I could write a custom filter set field to accomplish this instead of having it directly in the queryset? -

I can see the rabbitmq.conf file shows up on top of logs(which I think it means it loaded the file successfully??) main_rabbitmq | Config file(s): /etc/rabbitmq/rabbitmq.conf main_rabbitmq | /etc/rabbitmq/conf.d/10-default-guest-user.conf My Dockerfile: FROM rabbitmq:3.9.13-management # Define environment variables. ENV RABBITMQ_USER user ENV RABBITMQ_PASSWORD password ENV RABBITMQ_PID_FILE /var/lib/rabbitmq/mnesia/rabbitmq COPY ./myrabbit.conf /etc/rabbitmq/rabbitmq.conf ADD init.sh /init.sh RUN chmod +x /init.sh # Define default command CMD ["/init.sh"] The init.sh file is similar to this.
