Database service dependency not working properly in docker-compose
I am building a webapp in Django. I want to use Postgres instead of default sqlite and wanted to achieve this using docker-compose. Here is my docker-compose file. I expect postgres to spin up before my app but unfortunately this does not happen. Whenever I try to run the docker-compose up command, my webapp starts building first and eventually gives me an error of the database connectivity which is also attached. version: '3.7' networks: metagov_network: services: policykit_app: container_name: policykit restart: always build: context: . dockerfile: Dockerfile args: POSTGRES_DB: metagov POSTGRES_HOST: database POSTGRES_USER: postgres POSTGRES_PASSWORD: supersecretpassword ports: - "8081:8080" depends_on: - database networks: - metagov_network database: image: postgres:alpine restart: always environment: - "POSTGRES_DB=metagov" - "POSTGRES_USER=postgres" - "POSTGRES_PASSWORD=supersecretpassword" ports: - "5432:5432" networks: - metagov_network volumes: - metagov-storage:/var/lib/postgresql/data volumes: metagov-storage: I run the command: docker-compose up --build -d --force-recreate My Dockerfile looks like this: FROM ubuntu WORKDIR metagov RUN apt install postgresql-client -y RUN apt install python3-pip -y COPY policykit metagov RUN pip3 install --no-cache-dir -r metagov/requirements.txt EXPOSE 8000 ARG POSTGRES_DB ARG POSTGRES_HOST ARG POSTGRES_USER ARG POSTGRES_PASSWORD RUN python3 metagov/manage.py makemigrations RUN python3 metagov/manage.py migrate ENTRYPOINT ["python3"] CMD ["metagov/manage.py", "runserver", "0.0.0.0:8000"] And this is the error I get: django.db.utils.OperationalError: could not translate host … -
Is it possible to add Google Maps markers of locations read from a file in Django?
I'm developing a Django project and I'm trying to render a map that contains several markers of different locations. I want to read these locations from a file, but up till now I used JS and HTML to render a map that contains a single marker on it. Here is the JS code: function initMap() { const uluru = { lat: 0.0018211100000000001, lng: 0.009671981000000001 }; const map = new google.maps.Map(document.getElementById("map"), { zoom: 4, center: uluru, }); const marker = new google.maps.Marker({ position: uluru, map: map, title: "Turbine 7", }); } and the HTML code is a only a div that contains the position of the map inside of it: <div id="map"></div> and here is a picture of the final output: -

Django - second trigger of htmx tries to load an unexpected URL gives a 403 error
I have a table of cells, each with a different object instance, and using htmx to update the objects. I've created a CBV that takes the request.post from the htmx and saves the modified object to the db. The htmx does a hx-swap and loads a new <input> tag into my form, along with some background-color style based on the saved object. I can click on many cells and update several objects this way. This is working as expected and I don't see any errors. However, the second time that I try to update the same cell/object, I get a 403 error. This error does not show in the browser. The cell just seems unresponsive. I can continue updating other cells. The error shows up in my browser console. views asessmentdetail - view that loads template and retrieves all the objects to fill in the table def assessmentdetail(request, assess_pk, class_pk): """List the current grades for the assessment""" user = request.user assessment = Assessment.objects.get(id=assess_pk) classblock = Classroom.objects.get(id=class_pk) course_pk = classblock.course.pk objective_list = Objective.objects.all().filter( assessment=assess_pk).order_by('objective_name') student_list = Student.objects.all().filter( classroom=class_pk).order_by('nickname') gra = Grade.objects.filter( assessment=assess_pk).filter(cblock=classblock.id) context = {'objective_list': objective_list} new_or_update = gra.exists() grade_report = [str(new_or_update)] grade_list = [] grade_id_array = [] grade_report.append(len(objective_list)) # print(len(objective_list)) … -
how do I update fields in django

Function doesn't update in asyncio
I'm writing a bot in aiogram with a backend on django for postgresql (had the same issue before converting from pure psycopg2). One of the finite states I'm in, should constantly check for updates in the DB, except it doesn't happen. Here's the code for the loop in bot: @dp.message_handler(state=Current.start_state) async def func(msg: types.Message, state: FSMContext): async def res(): return await function(args) global ticket ticket = await res() while ticket == -1: ticket = await res() if ticket == -1: await asyncio.sleep(3) print(ticket) #debugging I've tried it without the function: @dp.message_handler(state=Current.start_state) async def func(msg: types.Message, state: FSMContext): global ticket ticket = await function(args) while ticket == -1: ticket = await function(args) if ticket == -1: await asyncio.sleep(3) print(ticket ) And many other combinations, including making the loop condition while = True and having a break in the loop for when the condition is met. And I can insure you, the results change, I can see that in pgAdmin4 and by running this function separately in another script while the bot is running. It seems to work sometimes if I manually change the information in DB, and even then, not always. Basically, whilst this loop is running for user A, another … -

How to enable console scripts in Django?
Running Python 3.6 on Redhat. I've installed an extremely complicated project. 5 engineers worked on this for years, but they are all gone now, so I've no one to ask.

How to filter in Django Rest Framework function based view?
So many documentation for filtering in Django rest framework but all the examples are in class based view. but I am trying to do the same in DRF function based view. I wanted to do multiple filter for my items queryset. I tried one way and it is working perfectly. Here first I am trying to search by item name or restaurant name in one request. then I take another keyword and try to filter restaurant name or item name based on restaurant city. It is working perfectly like if I hit this url http://localhost:8000/api/items/?keyword=lasagne&keyword1=paris then it gives me the perfect response. But What I am asking for is that now my code looks for this specific part is messy and I want to add more fields for multiple filtering. Which procedure to follow? Should I follow this one and multiple requests and trying to filter from this. Suppose now I want to filter the queryset based on dish_type, price, item_type, location and then search for items by name or restaurants by name #this is my models class Restaurant(models.Model): user = models.OneToOneField(CustomUser, related_name='restaurant', on_delete=models.CASCADE, null=False) name = models.CharField(max_length=200, blank=True, null=True) profile_picture = models.ImageField(null=True, blank=True) address = models.TextField(max_length=2000, blank=True, null=True) city … -

Django template - combining a loop within a loop and sorting by date
I have an array called Events. Within the Events array I have another array called Recurrences, using the Django-Recurrences library. I get the events context from my view as well as today's date and an end date: context['events'] = PartnerEvents.objects.filter(partner=context['partner']) context['today'] = datetime.combine(timezone.now().date(), time(0, 0)) context['end'] = context['today'] + timedelta(days=21) return context I then loop it out in my template as follows. {% for e in events %} {% for ts in e.recurrences.occurrences %} {% if ts >= today and ts <= end %} <p>{{ts|date:'d F'}}</p> {% endif %} {% endfor %} {% endfor %} It would then display all the events and occurrences, that will take place today and the next 21 days, eg 05 March 07 March 08 March 09 March 10 March 11 March 12 March 14 March 15 March 16 March 17 March 18 March 19 March 21 March 22 March 23 March 24 March 25 March 05 March 12 March 19 March However, since certain 'partners' can have more than 1 event on a day, it's causing the the other event to only be looped after the specific event.

The Python spacy module not working on Apache

Why is Permission table populated in test database, while others aren't (django python)?
While playing around with django testing I noticed that Permission table in test database is not empty (like, for example, User and tables of models defined by me) - it has all permissions from the real table. My questions: Is the Permission table the only prepopulated table? (I have trouble inspecting other tables, because db is in-memory) Where is it prepopulated (I also couldn't find)? Upon setting up test suit? Or just before executing each test method? Or maybe added to queryset everytime it is requested? -
