how to be able to add records using Http Methods on django
I'm creating a Django rest API authentication system and I want to return data in JSON format,the main purpose of this question is : I want to add or delete users only by adding fields on json format , not in the inputs that've created : this is my views.py : # Rendering plant data as json : def plant_json(request): data=list(new_Plant.objects.values()) return JsonResponse(data,safe=False) this is my output ( don't mind the values ) : [{"id": 5, "name": "dqsd", "adress": "sdq", "type": "PV", "location": "dqd", "list_gateway": "gggdds", "status": "etude"}, {"id": 6, "name": "fdsfds", "adress": "fsdfds", "type": "PV", "location": "fdsfds", "list_gateway": "fdsfs", "status": "etude"}, {"id": 7, "name": "sdqdssd", "adress": "dsdsq", "type": "HYBRID", "location": "dqsdqs", "list_gateway": "dsdqss", "status": "online"}] normally in order to add a new plant I've created a HTML template that has inputs where the user can add a plant , but what I want is that I can add a plant only by adding fields directly using json format ( using postman for example ) no need for the inputs. Thank you -

Database population with django models, module not found error
I am just getting started with the Django framework through the book "The Definitive Guide to Django." I used psycopg2 to write my SQL insert statements (Postgres) through a script named scrape.py. I wanted to switch to using the Django models, however, I get an django.core.exceptions.ImproperlyConfigured error when I try to run from models import articles. I first used import os os.environ['DJANGO_SETTINGS_MODULE'] = 'CannaMed.settings' But got the error File "/home/ian/CannaMed/venv/lib/python3.8/site-packages/django/db/models/base.py", line 127, in __new__ app_config = apps.get_containing_app_config(module) File "/home/ian/CannaMed/venv/lib/python3.8/site-packages/django/apps/registry.py", line 260, in get_containing_app_config self.check_apps_ready() File "/home/ian/CannaMed/venv/lib/python3.8/site-packages/django/apps/registry.py", line 137, in check_apps_ready settings.INSTALLED_APPS File "/home/ian/CannaMed/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 87, in __getattr__ self._setup(name) File "/home/ian/CannaMed/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 74, in _setup self._wrapped = Settings(settings_module) File "/home/ian/CannaMed/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 183, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/usr/lib/python3.8/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) ModuleNotFoundError: No module named 'CannaMed' I then added import django django.setup() and got the error: Traceback (most recent call last): File "scrape.py", line 2, in <module> django.setup() File "/home/ian/CannaMed/venv/lib/python3.8/site-packages/django/__init__.py", line 19, in setup configure_logging(settings.LOGGING_CONFIG, settings.LOGGING) File "/home/ian/CannaMed/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 87, in __getattr__ self._setup(name) File "/home/ian/CannaMed/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 67, in _setup raise ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: Requested setting LOGGING_CONFIG, but settings are not configured.

Django/Pandas/Website - Querying a pandas dataframe instead of database, is it possible?
My table has some advanced features and queries that Pandas can accomplish but a database can't, so I am wondering about the implications of using a pandas dataframe on the server as a read-only database. The setup would be the basetable being a big pandas dataframe (400mb) on the webserver, and users submit GET requests that filter it in unique ways in order to make charts off of the data. The question is are there serious costs and/or bottlenecks when many users query a webservers dataframe? I know databases are meant to serve many people concurrently, but is this a problem for my case? Further, after a user filters the table, I imagine this filtered table is temporarily saved during their session....could this lead to memory requirements of the webserver gettings wildly out of hand? (Ex: 1000 users x 200MB avg table size = 200GB of memory demanded) Any explanation and tips would be appreciated! -

How to create a Django queryset based on items from another
I'm using Django 2.2.28 and Python 3.7.7 in a legacy application. I have a display page that displays People based on a class PeopleQuerySet(models.QuerySet) that's filtered and paginated. This works, but I'd like to know if it's possible to do something like this: new_people_queryset = PeopleQuerySet() for person in existing_queryset.iterator(): if some_condition: new_people_queryset.add(person) Is there a way to do what I'm implying above; create an empty PeopleQuerySet() object and then insert people into it from a queryset that's the result of filtering? The some_condition thing is some arbitrary Python logic I'm using for illustration purposes here. Any ideas, pointers, etc. would be greatly appreciated. -
populating django database using migrations
I created an api that allows to read some data with filters based on the models I created. and launch the database is empty so I created a script to populate the database. I then dockerized the app and deployed to AWS. the issue here is that everytime the container restarts the script is re-run. I would like to use migrations to do this. how? for now the docker entrypoint is python manage.py wait_for_db python manage.py makemigrations API python manage.py migrate # python import_csv.py uwsgi --socket :9000 --workers 4 --master --enable-threads --module myapi.wsgi -

Load foreign model instances into queryset.values()
I have queryset that groups and aggregates some data: EmployeeAssessment.objects.all().annotate(month=TruncMonth('assessment_date')).values( 'month', 'assessed_employee', 'subject' ).annotate(average_score=Sum('scores__score') / Count('scores__score', distinct=True)) And because of .values() I get assessed_employee and subject as IDs rather than model instances I know that there are some similar questions here, but they're all talking about single relation, that can be reversed to get the needed data from related model. My problem is that I need to get two nested objects: "assessed_employee" and "subject". Both of them are ForeignKeys I use DRF serializer like this: class EmployeeAverageScoreSerializer(Serializer): month = DateField() assessed_employee = EmployeeSerializer() # <- ModelSerializer subject = AssessmentSubjectSerializer() # <- ModelSerializer average_score = FloatField() It is ok if I will have some subqueries or something, but I need a single queryset that still can be paginated. How can I load models by ID after applying ".values" or maybe what other way can I use to get that data without losing model instances in resulting queryset? -

Web app such as libgen using Python and SQL?
I'm trying to make a webapp almost like the website libgen essentially using Python that can access a MySQL database and query and search through the database in order to find what they are looking for. I'm a bit stuck on how to approach this as I believe using Django as a framework to access the database would be good but I can't seem to understand how to connect the database (which I have locally) to the project. But then I would need to be able to move this online for hosting. I would really appreciate the help. -
Null value in column violates not-null constraint after deleting objects incorrectly

Django makemirgations not updating database
