Django APScheduler not executing jobs according to schedule with Apache and mod_wsgi
I have a Django project that uses django-apscheduler with the following configuration: Apache virtualhost WSGIPassAuthorization On WSGIScriptAlias / /some/app/wsgi.py WSGIDaemonProcess some-app \ user=someapp threads=15 display-name=some-app \ python-path=/some/app/venv/lib/python3.7/site-packages WSGIProcessGroup some-app Scheduled tasks from pytz import utc from apscheduler.schedulers.background import BackgroundScheduler from django_apscheduler.jobstores import DjangoJobStore, register_events, register_job from administration.scheduled_tasks import add_db_backup, delete_old_db_backups scheduler = BackgroundScheduler(timezone=utc) scheduler.add_jobstore(DjangoJobStore(), 'default') register_events(scheduler) @register_job(scheduler, 'cron', hour='0', minute='0') def db_backups_job(): add_db_backup() delete_old_db_backups() scheduler.start() As expected, the scheduled job is visible in Django admin. Also, the jobs execute sometimes, for example the daily job above has executed seven times during this month, although today is 15th and it should thus have executed 15 times. Note that I have restarted Apache during this time. This seems to be a process lifetime issue. It seems that the mod_wsgi process is suspended and thus APScheduler jobs cannot run. What is the lifetime of the mod_wsgi process? How can I assure that the jobs execute according to schedule or at least daily? -
How Do I Load A Comments Form within the Blog Object View ? Or can those things somehow be loaded independently?
So I am in the process of creating a custom comments app for Django == 2.1 And I'd like to know how to load both the existing blog entry, and the comment form that will store the ContentType as blog instead of one of the other models which it can be associated with. The Method Resolution Order demands that that the leftmost View or mixin will be the one that is searched first for missing methods not declared within that respective View, or those Views that call the super().get() method ( form example ). Therefore I have concluded that the View for the Blog app should have the following code. blog/views.py class BLogTechObjectView(SingleObjectMixin, TemplateResponseMixin, BlogTechView): model = Blog slug_url_kwarg = 'blogtitle' template_name = 'extendsBlog.html' context_object_name = 'blog' slug_field = 'blog_name' def get(self, request, *args, **kwargs): blog = self.get_object() return render(request, 'extendsBlog.html', {'blog':blog}) comments/models.py class Comment(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') timestamp = models.DateTimeField(auto_now_add=True) content = models.TextField() def __str__(self): return '{} made this comment on : {} '.format(self.user, self.timestamp) def __unicode__(self): return '{} made this comment on : {} '.format(self.user, self.timestamp) comments/views.py class CommentFormView(generic.CreateView): form_class = CommentForm success_url = None template_name … -

Django: Show View after password entry
How can I return a View only after letting the user enter a password which is checked against the link? class Foo(models.Model): url = models.CharField(max_length=10) #a randomly created ASCII-string name = models.CharField(max_length=10) password = models.CharField(max_length=10) url_patterns = [path('foo/<url>/admin', views.foo, name='foo_admin'),] So a user goes to url: localhost/foo/bar now he should enter the correct password to see the content of model Foo with url='bar'. -
How to map an existing python class to a Django model
I'm writing a web scraper to get information about customers and appointment times to visit them. I have a class called Job that stores all the details about a specific job. (Some of its attributes are custom classes too e.g Client). class Job: def __init__(self, id_=None, client=Client(None), appointment=Appointment(address=Address(None)), folder=None, notes=None, specific_reqs=None, system_notes=None): self.id = id_ self.client = client self.appointment = appointment self.notes = notes self.folder = folder self.specific_reqs = specific_reqs self.system_notes = system_notes def set_appointment_date(self, time, time_format): pass def set_appointment_address(self, address, postcode): pass def __str__(self): pass My scraper works great as a stand alone app producing one instance of Job for each page of data scraped. I now want to save these instances to a Django database. I know I need to create a model to map the Job class onto but that's where I get lost. From the Django docs (https://docs.djangoproject.com/en2.1/howto/custom-model-fields/) it says in order to use my Job class in the Django model I don't have to change it at all. That's great - just what I want. but I can't follow how to create a model that maps to my Job class. Should it be something like from django.db import models import Job ,Client class JobField(models.Field): description … -
Django Form Not Rendering HTML from class HomeForm
For some reason I cannot get my Django form to render. I'm not sure what I'm missing. I'm trying to get the class HomeForm(forms.Form) to render on the myaccount/change.html page and have been unsuccessful. I'm new to Django so I might be missing a small detail somewhere but I thought I got everything covered from the djago documentation. If anyone can help me out it would be gladly appreciated.

Ignoring Test Files with Nose/unittest
I have two test files. One is standard TestCases. The other has selenium tests in it. I have a docker-compose file setup to run the selenium tests with their associated services. The tests run in bitbucket-pipelines. First it runs the test with the standard TestCases. Then in the next step it uses docker-compose to run the tests that include selenium since it needs compose to set up the selenium services. The issue I'm having is it's trying to run the selenium tests during the first step when there isn't any selenium containers running. I entered this in my Django settings file used for the first testing part: NOSE_ARGS = [ '--exclude=(__init__.py)', '--exclude=(../tests/selenium_tests.py)', '--exclude=(selenium_tests.py)', '--with-coverage', '--cover-package=sasite', '--with-xunit', '--xunit-file=test-results/nose/noseresults.xml', '--verbosity=3', '--cover-xml', '--cover-xml-file=test-results/nose/noseresults.xml', '--id-file=test-results/nose/noseids' ] and in my settings for the second: NOSE_ARGS = [ '--exclude=(__init__.py)', '--with-coverage', '--cover-package=sasite', '--with-xunit', '--xunit-file=test-results/nose/noseresults.xml', '--verbosity=3', '--cover-xml', '--cover-xml-file=test-results/nose/noseresults.xml', '--id-file=test-results/nose/noseids' ] As you can see, I want to exclude the selenium tests for the first part, and use them for the second. But even with my exclude in nose_args it still runs the selenium tests in the first part.

Django - loop using models.PositiveIntegerField variable

Or can I even use the for loop like this? I am new to python and Django so I really dont know how to solve it. Thanks for help :-) -
How to arrange posts from different models in Order of time when they were created
Intro: I have a 3 models user, post, group. User is able to make posts however each post has to belong to a group. I have 400 fixed groups. Users have to choose from the existing 400 groups for their posts. Users cannot add, delete, update group's. Furthermore: Users can become a member of groups and when they click on a certain group. They see all the posts in that group. Users can follow-unfollow other users. **What I have right now:**When a user signs-in. In his home page he sees. All the posts of the each individual group he is a member of. When all the posts from all the groups are done with. He then sees the posts of all the people he follows one by one What I want: I want the posts to be arranged by time Example: If one of the people he follows just wrote a post then that post is first. Chronologically the second post was in one of the groups that he is a member of. That post comes second... You get the idea Below are my models class Post(models.Model): user = models.ForeignKey(User, related_name='posts') group = models.ForeignKey(Group, related_name='posts') title = models.CharField(max_length=250, unique=True) message … -

How can I handle multiple image uploads without the server slowing down?

Overriding serializer create for nested serializer with many=True
I am trying to have the ClassificationResultsSerializer many Classifications by having a nested serializer as shown below. class ClassificationSerializer(serializers.ModelSerializer): class Meta: model = Classification fields = ('summary', 'wiki_url', 'score') class ClassificationResultsSerializer(serializers.ModelSerializer): owner = serializers.ReadOnlyField(source='owner.username') classifications = ClassificationSerializer(many=True) def create(self, validated_data): classifications_data = validated_data.pop('classifications', []) classificationresults = ClassificationResults.objects.create(**validated_data) for data in classifications_data: Classification.objects.create(classificationresults=classificationresults, **data) return classificationresults class Meta: model = ClassificationResults fields = ('id', 'owner', 'classifications') I defined the create method for ClassificationResultsSerializer to handle the nesting as per https://www.django-rest-framework.org/api-guide/relations/#writable-nested-serializers, and I call the ClassificationResultsSerializer in my views as such: serializer = ClassificationResultsSerializer(data={ 'owner': self.request.user, 'classifications': [ { 'summary': 'a summary', 'wiki_url': 'url', 'score': 1 } ] }) but I keep getting psycopg2.IntegrityError: null value in column "classifications" violates not-null constraint The reason I'm sure is because I'm popping classifications in create, then creating the classificationresults without classifications now being null, despite the documentation telling me to do this. How am I able to solve this problem?
