Operation of standard Django view, form and template code to update a model
I am trying to understand how a very regularly used code-form in Django views.py actually works. I see the following (or a variation) used a lot, but I can’t find a line-by-line explanation of how the code works – which I need if I am to use it confidently and modify when needed. I will start with the model then introduce urls.py the view and the form. I will go through the relevant parts of the code. I will consider: The model: #models.py class CC_Questions(models.Model): # defining choices in Model : https://docs.djangoproject.com/en/4.0/ref/models/fields/ personality = [ ('IF','IF'), ('IT','IT'), ('EF','EF'), ('ET','ET'), ] q_text = models.CharField('Question text', max_length=200) #C1_Type = models.CharField('Choice 1 Type', max_length=2) C1_Type = models.CharField(choices=personality, max_length=2) Choice1_text = models.CharField('Choice 1 text', max_length=100) #C2_Type = models.CharField('Choice 2 Type', max_length=2) C2_Type = models.CharField(choices=personality, max_length=2) Choice2_text = models.CharField('Choice 2 text', max_length=100) # def __str__(self): return self.q_text[:20] The url # #urls.py app_name = ‘polls’ urlpatterns = [ ….. # ex: /polls/p2create path('p2create/', p2_views.p2create, name='p2create'), … The view: #views.py from.forms import Anyform # def p2create(request): if request.method == 'POST': form = AnyForm(request.POST) if form.is_valid(): form.save() return redirect('/polls/p2') else: form = AnyForm() context = {'form' : form} return render(request, 'pollapp2/create.html', context) # The form: #forms.py # …. … -

What queryset should I do to select all One-to-one relations that are broken?
I have this 2 models : class Asset(models.Model): created = models.DateTimeField(auto_now_add=True) modified = models.DateTimeField(auto_now=True) ... some other fields ... class AssetConstructorData(models.Model): asset = models.OneToOneField( Asset, on_delete=models.CASCADE, primary_key=True, related_name='constructor_data', ) ... some other fields ... For some historical reason, I have some One-to-one which are broken : some AssetConstructorData object has not their corresponding Asset object. I would like to delete all AssetConstructorData objects that are broken. Actually I have done : for cd in AssetConstructorData.objects.all(): try: cd.asset except Asset.DoesNotExist: cd.delete() Which is definitively not optimized : Is that possible to make a queryset that selects all broken relations ? I tried with .filter(asset=None) and .filter(asset__isnull=True) but it does not work. -

Django-Tenants causes App_model does not exist with functional pytest
I have been trying to do this using functional test approach not class test class based approach: class SomeTest(TenantTestCase): def setup(): super().setup() def test_some_do_something(): #... test_code def test_some_do_something_again(): #... test_code_again The above class based approach works well since it can easily create a tenant based on TenantTestCase but then when try to replicate the above in normal functions., I face difficulties , another reason is I am using pytest for my test and pytest works better with Normal Functional test approach than Class test approach Function approach: def test_some_thing_using_functional_test_approach(): # .. some assertion code #The above causes error the app_model relation does not not exist . This is because they live in schemas and therefore how do I ensure the tenant is created first and accessed in a functional test approach to avoid this issue -
How to use model functions in Views for multiple instances in Django?

How to get .env to pre-commit + mypy + django-stubs
I try to configurate start mypy + django-stubs cheking before commiting. I use pre-commit for it.

How do I redirect from a view to a root URL in Django?
I'm trying to add a link to my django site that redirects from the catalog1 view to the catalog2 page. So basically, I want to go from .../catalog1 to .../catalog2/other-page. All the other answers that I've seen require redirecting to http://127.0.0.1:8000/ first, and then redirecting to catalog2, but I've set up the site so that http://127.0.0.1:8000/ automatically redirects to catalog1, so this isn't working. Any help would be appreciated. Thanks, FluffyGhost -

django dynamic forms setting max_length property

How to fix ERROR: Failed building wheel for psycopg2?
I am using ubuntu 20.04 and want to install django project dependencies using requirements.txt file. The project is using python3.9. and I've installed python3.9 and postgresql already. I already tried to install dependencies using pipfile, but it failed locking dependencies. installing dependencies give this error: Building wheels for collected packages: psycopg2 Building wheel for psycopg2 (setup.py) ... error ERROR: Command errored out with exit status 1: command: /usr/bin/python3 -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-fu9m38m8/psycopg2/setup.py'"'"'; __file__='"'"'/tmp/pip-install-fu9m38m8/psycopg2/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' bdist_wheel -d /tmp/pip-wheel-rqzwqrsw cwd: /tmp/pip-install-fu9m38m8/psycopg2/ Complete output (38 lines): running bdist_wheel running build running build_py creating build creating build/lib.linux-x86_64-3.8 creating build/lib.linux-x86_64-3.8/psycopg2 copying lib/sql.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/_json.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/_range.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/__init__.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/pool.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/errorcodes.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/extras.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/extensions.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/errors.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/tz.py -> build/lib.linux-x86_64-3.8/psycopg2 copying lib/_ipaddress.py -> build/lib.linux-x86_64-3.8/psycopg2 running build_ext building 'psycopg2._psycopg' extension creating build/temp.linux-x86_64-3.8 creating build/temp.linux-x86_64-3.8/psycopg x86_64-linux-gnu-gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g -fstack-protector-strong -Wformat -Werror=format-security -g -fwrapv -O2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -fPIC -DPSYCOPG_VERSION=2.9.1 (dt dec pq3 ext lo64) -DPSYCOPG_DEBUG=1 -DPG_VERSION_NUM=120009 -DHAVE_LO64=1 -DPSYCOPG_DEBUG=1 -I/usr/include/python3.8 -I. -I/usr/include/postgresql -I/usr/include/postgresql/12/server -I/usr/include/libxml2 -I/usr/include/mit-krb5 -c psycopg/psycopgmodule.c -o build/temp.linux-x86_64-3.8/psycopg/psycopgmodule.o … -
How to get class values in static method
I want to get the field value like we use self in Django models. class UserModel(Model): id = IDField() uid = TextField() @classmethod def get_user(cls): return cls.uid The class method, keep returning NONE instead of the string value of the uid field.

Finding the nearest observation station from National Weather Service API in Python/Django
So after finding the coordinates for the closest station, I need to extract the name of the station. This is an example of the response I'm working with: https://api.weather.gov/gridpoints/OKX/34,39/stations The station data is in the 'features' property. How do I go about extracting the name of the station based on the coordinates. -
Apscheduler stopped working randomly without any exception
I build a django webset and use apscheduler to do some scheduled tasks. Everything was alright at startup. But after some time, the scheduler refused to work and left nothing in log. The log just stopped without exception. Below is the framework of how I run the scheduler: from rpyc.utils.server import ThreadedServer class Command(BaseCommand): help = "Runs apscheduler." def handle(self, *args, **options): scheduler = BackgroundScheduler(timezone=settings.TIME_ZONE) scheduler.add_jobstore(DjangoJobStore(), "default") scheduler.start() server = ThreadedServer(SchedulerService(scheduler), port=settings.MY_RPC_PORT, protocol_config=protocol_config) try: # logging.info("Starting thread server...") server.start() except (KeyboardInterrupt, SystemExit): pass finally: scheduler.shutdown() And here are the dependencies: dependencies: - python=3.8.3=hcff3b4d_2 - apscheduler=3.6.3=py38_1 - django=3.2=pyhd3eb1b0_0 - pip: - django-apscheduler==0.6.0 - rpyc==5.0.1 What's more, while apscheduler was refusing to work, the rpyc server could still be connected and leave message in log. Can anyone help me to figure out what was wrong here? You have my gratitude.
