Filter queryset of django inline formset based on attribute of through model
I have a basic restaurant inventory tracking app that allows the user to create ingredients, menus, and items on the menus. For each item on a given menu, the user can list the required ingredients for that item along with a quantity required per ingredient for that item. Menu items have a many-to-many relationship with ingredients, and are connected via an "IngredientQuantity" through table. Here are my models: class Ingredient(models.Model): GRAM = 'Grams' OUNCE = 'Ounces' PIECE = 'Pieces' UNIT_CHOICES = [ ('Grams', 'Grams'), ('Ounces', 'Ounces'), ('Pieces', 'Pieces') ] user = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True) name = models.CharField(max_length=200) unitType = models.CharField(max_length=200, choices=UNIT_CHOICES, verbose_name='Unit') unitCost = models.DecimalField(max_digits=10, decimal_places=2, verbose_name='Unit Cost') inventoryQuantity = models.DecimalField(max_digits=10, decimal_places=2, verbose_name='Quantity') def __str__(self): return self.name + ' (' + self.unitType + ')' def totalCost(self): result = self.inventoryQuantity * self.unitCost return "{:.0f}".format(result) class Menu(models.Model): user = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True) name = models.CharField(max_length=200) timeCreated = models.DateTimeField(auto_now_add=True) timeUpdated = models.DateTimeField(auto_now=True) def __str__(self): return str(self.name) class MenuItem(models.Model): user = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True) name = models.CharField(max_length=200) price = models.DecimalField(max_digits=10, decimal_places=2) ingredients = models.ManyToManyField(Ingredient, through='IngredientQuantity') menu = models.ForeignKey(Menu, on_delete=models.CASCADE, null=True) def __str__(self): return self.name def itemCost(self): relevantIngredients = IngredientQuantity.objects.filter(menuItem=self) cost = 0 for ingredient in relevantIngredients: cost += (ingredient.ingredient.unitCost * ingredient.ingredientQuantity) … -
How to change the status code that is recieved in the response in case of specific exceptions in Django rest framework
I am adding some details to my Django model from a react frontend. Everything is working fine and the API request is made with Axios. The data that is being submitted is an OneToOne Field with the user and hence submitting more than once raises an Integrity error of Unique Constraint. But the response I receive back has a status of 200. This triggers a notification in my frontend that says details submitted every time the button is pressed. However. that is not being submitted the second time because of the Integrity Error. My question is if I handle the Integrity Error exception separately how can I send a different status rather than 200 as shown below config: {transitional: {…}, transformRequest: Array(1), transformResponse: Array(1), timeout: 0, adapter: ƒ, …} data: {message: 'UNIQUE constraint failed: teacher_teacherdetail.user_id'} headers: {content-length: '39', content-type: 'application/json'} request: XMLHttpRequest {onreadystatechange: null, readyState: 4, timeout: 0, withCredentials: false, upload: XMLHttpRequestUpload, …} status: 200 statusText: "OK" Currently I am handling the exception as below try: # some code except IntegrityError as e: message = { "error": str(e) } return Response(message) except Exception as e: message = { "message": "exception", "error": str(e) } return Response(message) -
How to synchronize Django database migration on VPS and inside django container?
I have a task to set up work with migrations. In this photo I am on the VPS and when I try to see apps migrations, there is only one migration file(0001_initial.py) in every app. And for example if I change something in models.py and run 'makemigrations & migrate' commands, the new migration file won't appear here on the VPS, it will only appear inside the django container And the question here is how can I set up migrations so that when I run docker-compose -f docker-compose.dev.yml exec web_dev python manage.py makemigrations docker-compose -f docker-compose.dev.yml exec web_dev python manage.py migrate commands from the VPS, migration files appear here in the VPS and not only inside the django container? -
Django with DRF APIs slows down after few weeks or months
I have Django with DRF sight and it has couple of APIs based on DRF with GenericAPI view and API view. The APIs is used to calculate XML vs XML and JSON vs JSON differences. Two objects are passed as body to these APIs and the API returns the no of differences and exact nodes at which the differences are found. It also respond with nodes which are added or removed. The sight and APIs work just fine when my environment is just up and running for few weeks say 2 weeks. I have recently observed that after a month or 3 weeks same APIs takes much more time to calculate the differences with same set of data. Usually it is very fast for example If we have large JSON object then 1k differences per second is processed. If we have pretty small JSON or XML object like 5 to 10 keys (very basic) the main library function which calculates the difference tales just about few milliseconds. So overall API time is like 200 ms. Now the issue that I have is after lets say 3 weeks or a month same very basic JSON object comparison (with just 5-10 keys) … -

Folium - Django: How to make a folium marker a link to another page
I'm generating a map using Folium with Django like so: views.py def viz(request): dg_map= folium.Map(location=[50.38175,6.2787], tiles= 'https://tiles.stadiamaps.com/tiles/alidade_smooth/{z}/{x}/{y}{r}.png?api_key=<MY_API_KEY>', attr= '&copy; <a href="https://stadiamaps.com/">Stadia Maps</a>, &copy; <a href="https://openmaptiles.org/">OpenMapTiles</a> &copy; <a href="http://openstreetmap.org">OpenStreetMap</a> contributors', zoom_start=10) map_details = fetch_data("SELECT id, firstname, lat, long FROM map_details") #helper func to query the DB for item in map_details: location = [item[2], item[3]] popup = f"{item[1]}'s Garden" marker = folium.Marker( location = location, popup = popup, icon=folium.Icon(color='darkgreen', icon="heart", prefix='fa')) marker.add_to(dg_map); m = dg_map._repr_html_() context = {'map': m} return render(request, 'accounts/viz.html', context) This is working as expected. However, I'd like each marker to redirect towards another page on-click. To make matters worse, I'd need to use the id that's querried in the SELECT statement and include it in the destination link, because the urlpattern of the destination pages is this: urls.py path('garden/<str:id>/', views.garden, name="garden"). What I found out so far: I found several suggestions on how to add an href to the pop-up (e.g. here) but this is not what I want as it requires the user to click twice. Some ideas on how to add custom js to Folium's output are mentioned here, but I think it's not implemented yet. I also found instructions on how this can be done … -

How to correctly access parent form's field/s from inline form clean method during Update

Wagtail: Get data from promote tab?
When creating a new page, there's a "Promote" tab. Under the "for search engines" section there's a "title tag" and a "meta description" value. As I understand, the "title tag" sets the document's title and the "meta description" sets the document's meta description. But how would I actually use these values in my page template? I searched far and wide, but it seems that Wagtail's documentation explains nothing about the Promote tab or what purpose it serves. Are the values defined there available as template variables? How would I actually access a page's "title tag" or "meta description"? -

Running Django's collectstatic in Dockerfile produces empty directory
I'm trying to run Django from a Docker container on Heroku, but to make that work, I need to run python manage.py collectstatic during my build phase. To achieve that, I wrote the following Dockerfile: # Set up image FROM python:3.10 WORKDIR /usr/src/app ENV PYTHONDONTWRITEBYTECODE=1 ENV PYTHONUNBUFFERED=1 # Install poetry and identify Python dependencies RUN pip install poetry COPY pyproject.toml /usr/src/app/ # Install Python dependencies RUN set -x \ && apt update -y \ && apt install -y \ libpq-dev \ gcc \ && poetry config virtualenvs.create false \ && poetry install --no-ansi # Copy source into image COPY . /usr/src/app/ # Collect static files RUN python -m manage collectstatic -v 3 --no-input The Dockerfile builds just fine, and I can even see that collectstatic is running and collecting the appropriate files during the build. However, when the build is finished, the only evidence that collectstatic ran is an empty directory called staticfiles. If I run collectstatic again inside of my container, collectstatic works just fine, but since Heroku doesn't persist files created after the build stage, they disappear when my app restarts. I found a few SO answers discussing how to get collectstatic to run inside a Dockerfile, but … -
