django-filters filter by Boolean field with DRF
I'm following the tutorial here: https://www.django-rest-framework.org/api-guide/filtering/#djangofilterbackend (specifically the django-filter-backend section) and I am unable to get this to work. My goal is to retrieve a list of "containers" that have the "in_use" field set to True, but it keeps returning all the records in the table. I can't really see what I am missing. I have added django-filters to my installed apps list and also added this to my REST_FRAMEWORK block: 'DEFAULT_FILTER_BACKENDS': ['django_filters.rest_framework.DjangoFilterBackend'] This is the API endpoint I'm trying to hit in postman: http://127.0.0.1:8000/displaydata/containers?in_use=True I've tried passing both 'True' and 'true', as well as 0s and 1s. views.py class ContainerViews(APIView): def get(self, request, id=None): if id: container = Container.objects.get(id=id) serializer = ContainerSerializer(container) return Response({"status": "success", "data": serializer.data}, status=status.HTTP_200_OK) else: containers = Container.objects.all() serializer = ContainerSerializer(containers, many=True) filter_backends = [DjangoFilterBackend] filterset_fields = ['in_use'] return Response({"status": "success", "data": serializer.data}, status=status.HTTP_200_OK) -

Django - How to register route with query parameters?
Im very new to Django, struggling to find the answer Im looking for. Please bear with me. In my app/urls.py file I have router = routers.DefaultRouter() router.register(r'drugs', views.DrugViewSet) In my views.py file I have class DrugViewSet(viewsets.ModelViewSet): queryset = Drug.objects.all().order_by('name') serializer_class = DrugSerializer And my DrugSerializer class looks like class DrugSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Drug fields = ('id', 'name', 'description', 'recommended_dose_mg', 'count', 'create_date', 'update_date') So when I do a GET on /drugs, I correctly get the list of drugs. And when I take a UUID (primary key) on a specific drug and do a GET on /drugs/<primary_key>, it correctly pulls the specific drug. However, I want the GET on /drugs/<primary_key> to display different data. I want to join it with another model that I have and return a new json response. How exactly would I do this? -

How to actually prove that the user consented to data processing while he submitted the form?
A user submits a form and opts in to receive a newsletter. What do I need to do to prove later that he actually did opt in? If I store submitted form data in a db table then I am able to manually create and modify entries, so I could just change his False to True and therefore db entries don't prove anything. I have a django website if it makes any difference. -

Docker with venv or without?
I am new in Docker and learning it, and my question is that do I have to use venv in Docker or isn't it important? Because I couldn't configure venv in docker, it gives me an error like cannot import Django activate venv..., I read some answers but couldn't get answer, some people say need to use venv others not important. My DOckerfile FROM python:3.8 #set environment variables ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 RUN python3 -m venv venv #Set work directory WORKDIR /code/ #Install dependencies COPY requirements.txt . RUN . /venv/bin/activate && pip install -r requirements.txt COPY . /code/ If I don't use venv Docker runs fine, but when it comes to install package it gives me warning like WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead:... Can someone explain clearly it? Thanks in advance -

Is it safe to delete a Django QuerySet that may be empty?
Is it safe to attempt to delete a QuerySet that might be empty? In other words, if I am not sure if the name "MJ" exists, is there any functional difference between these 2 approaches?

Интеграция данных парсера с Django [closed]
Я хочу сделать сайт, на котором можно будет посмотреть информацию о разных вузах. У меня готовы парсеры, но я не понимаю, как можно правильно интегрировать парсеры в Django приложение... Когда я искал информацию по этому поводу, одним рекомендовали использовать django-admin команды, другим использовать парсеры. Я не понимаю, что использовать лучше, у чего какие плюсы и что стоит в итоге выбрать? На данный момент у меня парсеры заливают информацию в стороннюю бд и через класс вытягивается в html форму.

Django Haystack select which fields to search
Suppose I have a Person model looking like this: class Person(models.Model): title = models.CharField(max_length=300, blank=True, null=True) first_name = models.CharField(max_length=300, blank=True, null=True) last_name = models.CharField(max_length=300, blank=False, null=False) And a Haystack search index like this: class NoteIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.CharField(document=True, use_template=True) title = indexes.CharField(model_attr='title') first_name = indexes.CharField(model_attr='first_name') last_name = indexes.CharField(model_attr='last_name') Say the template includes all three fields(firstname, lastname and title). If users should be able to choose in which fields to search for, do I need to build seperate indices for all possible permutations? Or can I narrow down the search to one or two of the three fields? If so how? I know that I am able to filter SearchQuerySets using .filter(). SearchQuerySet().filter(first_name='foo') But this filters the set for exact values. Even __icontains is limited to one field filtering. -

Understanding Model.from_db() in Django
I was reading Django Official Doc for Model, it reads: classmethod Model.from_db(db, field_names, values)¶ The from_db() method can be used to customize model instance creation when loading from the database. The db argument contains the database alias for the database the model is loaded from, field_names contains the names of all loaded fields, and values contains the loaded values for each field in field_names. The field_names are in the same order as the values. If all of the model’s fields are present, then values are guaranteed to be in the order __init__() expects them. That is, the instance can be created by cls(*values). If any fields are deferred, they won’t appear in field_names. In that case, assign a value of django.db.models.DEFERRED to each of the missing fields. I am completely lost when reading above. 1st perception: "when loading from the database": for me, loading means reading / retrieving data from database, which means the model instance already exists or is created and stored in DB. 2nd perception: "be used to customize model instance creation", as well as the 2nd paragraph all makes me feel that this from_db() is for model instance creation, which conflicts with my 1st perception. Q: Can … -
How can I return the refresh token using python-social-auth and django-graphql-auth?

I just don't know where to get the refresh token, it seems to be not in the extra_data. I am already dealing with this problem for hours and all the search results are no help. Please, any guidance is really appreciated.
