Django DRF - Unable to change user password as user at request is None
my application has an endpoint to change a users password using Django rest framework (DRF).

currently I'm writing a simple todolist with django. I have a view and html file for showing the list of items, and I want a number for each task in the table starting from 1. I'm using {% footloop.counter %} for that in my template. Everything was ok until I wrote the paginator. when you choose to go to the next page, the counter starts from 1 again ,therefor the numbers in the table in each page start from one too. but I want the numbers to be continued in order until the last page. Is there any template tags or code snippets for that?

Django refreshing records at template only after re-running server
I've just started learning Django and I making my first App. I'm having that weird problem when i adding record to database, it actually adding it there but it won't show them at my page until i reload server by following command python manage.py runserver views.py def createStudent(request): form = StudentForm() if request.method == "POST": form = StudentForm(request.POST, request.FILES) if form.is_valid(): form.save() return redirect("homePage") context = {"form": form} return render(request, "pages/addStudent.html", context) models.py class Students(models.Model): name = models.CharField(max_length=200) surname = models.CharField(max_length=200) card_id = models.IntegerField() unique_id = models.UUIDField( default=uuid.uuid4, unique=True, primary_key=True, editable=False) student_image = models.ImageField(null=True, blank=True, default="default_student.jpg") class Meta: verbose_name_plural = 'Students' #Methods def __str__(self): return f'{self.name} {self.surname}' addStudent.html {% extends "main.html" %} {% block addStudent %} <form method="POST" enctype="multipart/form-data"> {% csrf_token %} {{form.as_p}} <input type="submit"/> </form> {% endblock addStudent %} I think that bug appeared after I've started working with static files and added student_image = models.ImageField(null=True, blank=True, default="default_student.jpg") Have anyone faced that problem before? -

Django Model Struct within a Struct?
I'm trying to create a structure within a structure under Django's models.py. I know how to do this in C but am new to python. For example, I have a class: class OneDay(models.Model) hour1 = ? hour2 = ? ... hour23 = ? hour24 = ? Each hour will have a list of identical properties. I want to apply these properties to every single hour within the OneDay class. I don't believe they are ForeignKeys. class PeriodProperties(models.Model) isX = boolean isY = boolean isZ = boolean R = number P = number So with this I would be able to look up: hour5.isX == false? hour10.R > 50%? Something like that. Can anyone point me in the right direction? Thank you. -

How can I fix/ workaround this KeyError when I try to extract from a json via my python API request?

Django update index after adding records to db programmatically
I added a number of records to a Django db table (machina forums) directly via a script (ie: I did not use the site admin interface). The structure seemed fairly straightforward with no foreign keys in other tables. However the resulting displays are uneven. In a forum index display all of the children forums display under a category. However if I go into the category, only forums added via the admin interface are visible. There does not appear to be any difference in the db records between those that were added programmatically and those added via the admin interface. I am guessing the issue has to do with indexes on the table. However when I use a GUI to view the db all of the indexes show "result set is empty." Any ideas about what is causing the problem and if it is index related, how do I update the index? -
How to implement an external python code to a Django web server?
as from the title, I am trying to implement an external python code to a Django web server. I am quite new to programming so any hints will be surely helpful. Long story short: I am trying to set up a form where the user have to insert an aminoacidic sequence. This sequence should pass to my python script, that is able to compare it with all the sequences already present in the database and gives as a result the most similar ones. My problem is that I am not able to let my form and my script talk each others. I have followed the Django documentation here https://docs.djangoproject.com/en/3.2/topics/forms/ but this did't helped too much.

How can I pre-process a file's contents being saved into a FileField in Django?
There's a .csv being saved into a FileField in Django 2.2. Before it gets saved, I want to delete some rows in it. This is what I have so far: # A Custom File Field that will modify the file contents before saving it class CustomFileField(models.FileField): # The method that gets called before the save happens def pre_save(self, model_instance, add): file_field = super().pre_save(model_instance, add) file_field = self.update_file_contents(file_field) return file_field def update_file_contents(self, file_field): # NEED TO SOMEHOW UPDATE THE CONTENTS OF # THE file_field HERE BEFORE RETURNING IT return file_field # The model that uses this Custom File Field class MyModel(models.Model): my_csv_file = CustomFileField(upload_to='results/%Y/%m/%d/') I'm not quite sure what my update_file_contents method needs to do to update the contents of the file. Has the file been saved to the filesystem by the time my method is called? Or is it still in memory? Or should I forget making a custom FileField, and simply override my MyModel's save method, so that after the file is saved to the filesystem, I open it again, and modify it like I would any file? -
Trouble trying to get size of Celery queue using redis-cli (for a Django app)
I'm using Django==2.2.24 and celery[redis]==4.4.7. I want to get the length of my celery queues, so that I can use this information for autoscaling purposes in AWS EC2. I found the following piece of documentation: https://docs.celeryproject.org/en/v4.4.7/userguide/monitoring.html#redis Redis If you’re using Redis as the broker, you can monitor the Celery cluster using the redis-cli command to list lengths of queues. Inspecting queues Finding the number of tasks in a queue: $ redis-cli -h HOST -p PORT -n DATABASE_NUMBER llen QUEUE_NAME The default queue is named celery. To get all available queues, invoke: $ redis-cli -h HOST -p PORT -n DATABASE_NUMBER keys \* Note Queue keys only exists when there are tasks in them, so if a key doesn’t exist it simply means there are no messages in that queue. This is because in Redis a list with no elements in it is automatically removed, and hence it won’t show up in the keys command output, and llen for that list returns 0. Also, if you’re using Redis for other purposes, the output of the keys command will include unrelated values stored in the database. The recommended way around this is to use a dedicated DATABASE_NUMBER for Celery, you can also use … -

What exactly the reverse query name in its related model in Django?
I got pretty much the same problem as in Django - reverse query name clash. for the following code: class Supplier(models.Model): unique_id = models.IntegerField(unique=True) name = models.CharField(max_length=255, unique=True) rating = models.FloatField(null=True) last_updated = models.DateTimeField(auto_now=True) default_tariff = models.ForeignKey('Tariff') class Tariff(models.Model): name = models.CharField(max_length=255) supplier = models.ForeignKey(Supplier) end_date = models.DateField(null=True, blank=True) payment_method = models.ManyToManyField(PaymentMethod) region = models.ManyToManyField(Region) My question is: why does the reverse query name for Supplier.default_tariff clashes with the field name Tariff.supplier. I read the docs and I think it should be something like Supplier.default_tariff_set? -

RabbitMQ mkdir: /var/db/rabbitmq/mnesia: Permission denied
I have uploaded my Django project to the server. Everything works except using Celery. The server uses FreeBSD. Erlang is uploaded, but I have a problem with RabbitMQ. I downloaded rabbitmq-server-generic-unix-3.9.7.tar.xz and then unpacked it in cd /usr/home/my_login/RabbitMQ/. When I try to start the server with cd /usr/home/my_login/RabbitMQ/rabbitmq_server-3.9.7/sbin/rabbitmq-server I am getting a message about the lack of access to create a DB in the path as below mkdir: /var/db/rabbitmq/mnesia: Permission denied Failed to create directory: /var/db/rabbitmq/mnesia So I tried somehow to manually set this path to be different in cd /usr/home/my_login/RabbitMQ/rabbitmq_server-3.9.7/etc/rabbitmq/rabbitmq.conf. In the file I added: RABBITMQ_MNESIA_DIR=/usr/home/my_login/RabbitMQ/rabbitmq_server-3.9.7/db/ But that didn't help either, and I still don't know how to deal with it. I can't access root or sudo commands there -
