Here's what I wanted to know
Well thanks for this but my doubt is different, I've a question that I had created a web app using Django. This was a CRUD web app but I want is , how can I implement multiple create and multiple delete features?
As you may have seen django admin panel and what we do to delete is just checking checkbox of data to be deleted and then select action to delete and click on go. That's something similar I want to do but for bulk create I want to have a button for adding more inputs or just a first input where user can tell no of inputs and then those input fields will be generated with a single submit button so that if user has filled all the fields then user can submit all the data by clicking on that single submit button.
And bulk deleting kinda similar with django admin panel bulk delete feature.
objects.bulk_create

Hello, please how can I develop a multiuser login based on role with a lecturer logging in with an email and password whiles a student logs in with index number and password
why you can't use same email and password?
Пейн✙
or create user with indexes, but with different permissions?
Ana
why you can't use same email and password?
No
I want to use index number for students and email for lecturers
Charly
Ana
What have you tried? Where are you stuck?
Firstly I created two separate login pages for both users but my supervisor asked me to merge the two logins so that if a user enter details the system will be able to know it's a lecturer or student
Ana
So right now I want to have one login page for both of them

i suggest check firstly if input is email
else - student
Adrian
You can set specific role for each user, and show pages depends on the user's role.
Adrian
In other hand, you can use two admin pages for admin the user's, for that you need to use two proxy models

Did someone use dockerized django with local postgresql (not in docker)?
Денис
I have problems with connection
Adrian
Did someone use dockerized django with local postgresql (not in docker)?
Yes, you need to put the option network whit the value "host" in your docker file, and use Django as local
Adrian
With that, you use docker as a service

I have a db container that expose the port 9051, and in the django container I consume that service using the host 127.0.0.1 and the share port of db container

Hello everyone
I have a custom tag
@register.simple_tag
def category_list() -> dict:
return {
"categories": Category.objects.all(),
}
I know that i can return just queryset, but i want do it in dictionary and here is my question. How can i get the values in template from this dictionary? p.s. getting values like from views doesn’t work with custom template tags
Anshuman
Sr if you want dictionary key then you have to use keys example
Category.keys() or if you want to values then use .values() instead of keys
Bhaumik
I can't see rules when click on "Read the rules"
Maxim

Cat=category.objects.filter().values('id','name')
for i in cat:
for k,l in i.items():
Print(k,l)
Or you can do like this also

I'm making a Django app where I want to upload files and save them into categorical folders:
On the models.py I have these lines:
book_series = models.Charfield()
book_title = models.FileField(upload_to={f"media/{book_series}"
I made a pre_save signal that creates the book_series folder before an instance is saved:
@receiver(pre_save, sender=Book)
def create_folder(sender, instance, **kwargs):
os.mkdir(BASE_DIR+ instance.book_series)
The signal creates the required folder, however the files are stored in another folder called <django.db.models.fields.CharField> which is the type of the book_series field.
How do I make it save in the required folder (ie the book_series' name instead of its type)?

upload_to can get a callable that accepts the instance that is being saved and the filename.
so you can easily manage which folder to upload the file

I implemented my function like this:
def create_series_folder(instance, filename):
if not os.path.exists(f"{BASE_DIR}/media/books/{instance.series}"):
os.mkdir(f"{BASE_DIR}/media/books/{instance.series}")
return os.path.join(f"{BASE_DIR}/media/books/{instance.series}", filename)

But I am getting this error:

do not "mkdir".

return os.path.join(f"{BASE_DIR}/media/books/{instance.series}", filename)
in ur case you return "books/{instance.series}/{filename}"
Mojo
in ur case you return "books/{instance.series}/{filename}"
I changed the function to this:
def create_series_folder(instance, filename):
return f"/media/lectures/{instance.series}/{filename}"
Still getting the same suspicious error

How to download csv file asynchronously in django with celery.

Hi, you need to use Django channels, to connect front and back, and after you create the file with celery, send it to the front using the channel.
Adrian

I think you need to do that with JavaScript, after read the qr, after the user's confirmation, you redirect to other page.

How to accept user input on celery task?
1. Create a celery Task called generate_file which accepts the following parameters:
a. filename: name of the file to be generated.
b. data count: count of the random data to be inserted in the CSV (if provided 10 as the input
then the file should contain 10 rows with some random data)
How to get user input in celery task?
Am completely new to celery. Struggling a bit now
Adrian
How to accept user input on celery task?
You pass the parameters in the function. In your API, you get the user's info and run the task in celery, then process data and create the file with celery. When it finish, you send the data using channels
Adrian
You need to understand that celery is a different server, and is different that you Django server that the user is consume. For that reason, you can't get a direct response from celery and need to use channels
Adrian
For that, you should connect to the websocets in JS, and use a asynchronous server for production environment

ofc. Multiple templates within a view does not make sense.
I think OP is asking for the inheritance.
