Django: Integrity error not null for ForeignKey id field
I have a model which contains ForeignKeys to a number of other models and find, for some reason, I am able to save one of these models absolutely fine, but another I receive a fault message saying: IntegrityError: NOT NULL constraint failed: app_eofsr.flight_id See below for my models.py: # models.py class Aircraft(models.Model): esn = models.IntegerField() acid = models.CharField(max_length=8) engpos = models.IntegerField() operator = models.CharField(max_length=5, default='---') fleet = models.ForeignKey(Fleet, blank=True) slug = models.SlugField(default=None, editable=False, max_length=50, unique=True) class EoFSR(models.Model): datetime_eofsr = models.DateTimeField(default=None) flight_number = models.CharField(max_length=10) city_from = models.CharField(max_length=4) city_to = models.CharField(max_length=4) and these both feed into this model: # models.py class Flight(models.Model): flight_number = models.CharField(max_length=10) city_from = models.CharField(max_length=4, default=None) city_to = models.CharField(max_length=4, default=None) datetime_start = models.DateTimeField(default=None) aircraft = models.ForeignKey(Aircraft, on_delete=models.CASCADE) eofsr = models.ForeignKey(EoFSR, on_delete=models.CASCADE) The odd thing being, I can save an Aircraft record no problem at all, but cannot save an EoFSR record and receive the NOT NULL constraint error message. I've done the usual deleting of the migrations and even tried deleting the db.sqlite3, but still no luck! Any suggestions? -

Gunicorn taking up 100% on 72 core cpu (Django + Nginx)
I have a Django app with Nginx , gunicorn and postgresql as database. I have a aws server c5.18xlarge (72 cores and 137 gb ram). The problem is it gets slow with only 50 concurrent users. Using htop I found out that most of the cpu usage and ram is used by gunicorn workers and postgreql workers. Here is the htop screenshot: In the screenshot the usage is lower (38% load and around 100 gb of ram used ) because users are less. But as soon as there are 50 + concurrent users the usage goes to 100% in both cpu and ram. Here is the gunicorn worker settings: NAME="django_app" # Name of the application DJANGODIR=/home/ubuntu/bodhiai # Django project directory SOCKFILE=/home/ubuntu/env/run/gunicorn.sock # we will communicte using this unix socket USER=ubuntu # the user to run as GROUP=ubuntu # the group to run as NUM_WORKERS=72 # how many worker processes should Gunicorn sp TIMEOUT=120 DJANGO_SETTINGS_MODULE=app.settings # which settings file should Django use DJANGO_WSGI_MODULE=app.wsgi # WSGI module name echo "Starting $NAME as `whoami`" # Activate the virtual environment cd $DJANGODIR source /home/ubuntu/env/bin/activate export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE export PYTHONPATH=$DJANGODIR:$PYTHONPATH # Create the run directory if it doesn't exist RUNDIR=$(dirname $SOCKFILE) test -d $RUNDIR || mkdir … -
In Django, how to create join on either primary keys?
So, in Django, we have two models. model1(models): pk1 = models.pk(model2, on_delete=models.CASCADE) pk2 = models.pk(model2, on_delete=models.CASCADE) model2(models) somefield = models.charfield() I'd like to create a query to join then and match on either the first primary key or the second The sql equivalent would be select * from model1 join model2 on (model2.id = model1.pk1__id or model2.id = model1.pk2__id) for now I'm stucked with Model1.objects.select_related('model2') which always match on the first pk -
Change colors using CSS on a bootstrap .collapsed selector
Here is the important code in my Django template: <a class="notibell" data-toggle="collapse" href="#pgsettings"><i class="fa fa-bell"></i></a> <div class="collapse" id="pgsettings"> # content to show using the toggle anchor tag above. </div> I'm using this css in the page <head>: <style type="text/css"> .notibell.collapsed { color: green !important; text-shadow: 2px 2px 2px #ccc; } .notibell { color: red; text-shadow: 2px 2px 2px #ccc; } </style> On page load, the icon color is red (should be green). Then on click, the color remains red (correct color for expanded div). And then another click and the color changes to green (correct color for collapsed div). Then from this point forward the toggle and colors change correctly. The problem is on the page load, the color renders incorrectly despite the !important condition. I've also tried loading css in the head before and after bootstrap loads, but this hasn't made a difference. Thanks in advance, any help is appreciated. -
Django filtering DB items in a chain sequence
I am trying to build a project where I have a DB with toys where there are brands, each brand have products, the products have variety of sizes and sizes have colors. What I want to achieve is to have a home page with filtered the brands which I manage to achieve with the views.py below: def Index(request): toys = Toys.objects.values('brand').distinct().order_by('brand') context = {'index': toys } return render(request, 'index.html', context) with models.py class Vehicles(models.Model): brand= models.IntegerField(max_length=255) product = models.CharField(max_length=255) size = models.CharField(max_length=255) color = models.CharField(max_length=255) Now on the main page I have a list with all the different brans, what I'm trying to do is when I click on any Brand for the home page to redirect me to a result page with list of the Brand's products, product will lead to all available sizes and so on. How to implement that in the views? -
Multiple session in R
Can we create multiple sessions in R language . I am not using Rstudio or shiny app . I am just integrating R and python using pip module pypeR. I cannot see any R code where i can learn to create session. My requirement is to create a new session for every R request from python. Because whenever there are two requests to R at the same time my server gets blocked. Also i have used "pypeR" module to integrate R with python. I am a newbie in R as i have worked more in python.I have searched a lot about this issue and it seems to me that R works only in single session when called as a script through python. Any help would be appreciated. -
Is it good or bad practice to reference a single library.py file with all imports?
I am making a Django project with multiple apps and was wondering if it would be considered good or bad practice to create a single library.py file with all the "import x" and "from x import y, z" statements and then simply put "from library.py import *" at the top of every other file? What would be considered best practice for managing your imported libraries like this? Thanks for the help. -

Cannot use ArrayField from Djongo Models
I'm trying to make an app with Django using MongoDB as my database engine, so I'm using Djongo as ORM. In my models, I have defined a Client class, which is intended to contain an array of Profiles (authorized people to login in name of client).

Django modeltranslation TranslationOptions add external attribute to a model field

Celery task and mysql
I will try to simplify this question as much as possible. I have a django project that uses celery tasks for some async job. For simplicity, let's say I have an order. In task, I update the order from waiting to in progress. @task(bind=True) # pylint: disable=E1102 def mytask(self, id: str): """This is my custom task """ order = Order.objects.get(pk=id) order.status = IN_PROGRESS order.save() print(order.status) # This returns 'in progress' But after the task is done, it revers the state to waiting and I'm not sure why. Could be transaction isolation of MySQL, but what would be a way to do this most cleanly there?
