Update multiple rows with Django (different ids) using different values for each id (as keys)
Let's say I have a model: I have some items: grocery = { status : True, fruits: ['1', '23', '55'], comments: {'1': "test", '23': "test2", '55': ""} I have a rough potential Django update query: Fruit.objects.all().filter(id__in=grocery.get('fruits')).update(status=grocery.get('status'), comment=grocery.get('comments')) I'm successfully updating the status but I want to dynamically update the comments so that if the Fruit object in question has, for example, id: 23, the fruit comment will be test2, or if the object has 'id: 55' it will be '' -
Django - Date problem in CRUD application
I'm using flatpickr for date informations in my Django application. The problem is when I want to update worker informations, in edit.html page default value of birth_date is not displaying correctly. For example, I've created worker Xen who was born in 01-05-1997, and click to update his name, in birth_date input it displays today's date. Here are my codes: forms.py class WorkerForm(ModelForm): class Meta: model = Worker fields = "__all__" widgets = { 'birth_date': DateTimeInput(format='%Y-%m-%d %H:%M:%S', attrs={'class':'datetimefield'}) } models.py: class Worker(models.Model): ... birth_date = models.DateTimeField(blank=True, null=True) edit.html: ... <div class="form-group row"> <label class="col-sm-2 col-form-label">İşçinin doğum tarixi</label> <div class="col-sm-4"> <input class="datetimefield" type="date" name="birth_date" id="birth_date" value="{{ worker.birth_date }}" /> </div> </div> ... <script> window.addEventListener("DOMContentLoaded", function () { flatpickr(".datetimefield", { enableTime: true, enableSeconds: true, dateFormat: "Y-m-d H:i:S", time_24hr: true, locale: "az", }); }); </script> -

Django how the query GenericForeignKey relation(s)?
I want to display my users the content they have already brought by the "my_purchases" view (see below). For each object the user buy's a license is getting created and placed at the Licenses model: licensable_models = models.Q(app_label='App', model='model1') | \ models.Q(app_label='App', model='model2') class Licenses(models.Model): content_type = models.ForeignKey(ContentType, limit_choices_to=licensable_models, on_delete=models.CASCADE) object_id = models.CharField(max_length=36) content_object = GenericForeignKey('content_type', 'object_id') license_holder = models.ForeignKey(User, verbose_name="License Holder", on_delete=models.CASCADE, null=True) paid_amount_usd = models.DecimalField(verbose_name="License Price (USD)", max_digits=8, decimal_places=2, validators=[MinValueValidator(Decimal('0.01'))], null=False) paid_date = models.DateTimeField(auto_now=True) class Meta: verbose_name = "License" verbose_name_plural = "Licenses" ordering = ['-paid_date'] Creating a license and accessing the content after payment works fine!

Django rest raising error "The submitted data was not a file. Check the encoding type on the form." to angualar Http Client
The are any solutions to the problem but m not able to find the root cause and also to mention no of the solution is working in my case.

Django save user and profile with signals
Im still learning Django and I am stuck at user registration / profile creation. My goal So, the purpose of this is to save the new user and at the same time save the profile of the new user with de data from the form. I use 2 forms u_form and p_form.

Django does not gracefully close MySQL connection upon shutdown when run through uWSGI
I have a Django 2.2.6 running under uWSGI 2.0.18, with 6 pre-forking worker processes. Each of these has their own MySQL connection socket (600 second CONN_MAX_AGE). Everything works fine but when a worker process is recycled or shutdown, the uwsgi log ironically says: Gracefully killing worker 6 (pid: 101)... But MySQL says: 2020-10-22T10:15:35.923061Z 8 [Note] Aborted connection 8 to db: 'xxxx' user: 'xxxx' host: '172.22.0.5' (Got an error reading communication packets) It doesn't hurt anything but the MySQL error log gets spammed full of these as I let uWSGI recycle the workers every 10 minutes and I have multiple servers. It would be good if Django could catch the uWSGI worker process "graceful shutdown" and close the mysql socket before dying. Maybe it does and I'm configuring this setup wrong. Maybe it can't. I'll dig in myself but thought I'd ask as well.. -

Django get fields of the ForeignKey Model efficiently?

Dockerized Django project deployment with supervisor - what is the correct way?
The cookiecutter-django docs are great, got the django project dockerized and it runs. Even the Supervisor example works flawlessly. Though when it comes to a new deployment, I wonder what the correct way of doing this is. Clearly, I need to run: $ docker-compose -f production.yml build But my guess is that I would have to stop supervisor first: $ sudo supervisorctl stop {{ my_project_slug }} and then run $ docker-compose -f production.yml build followed by this to bring the project back up: $ sudo supervisorctl start {{ my_project_slug }} Is that correct? Or is it ok to run the build command without stopping supervisor? -
