How to use `docker compose exec` with both grep and ANSI color?
I'm only casually familiar with Docker, and how TTYs work in Linux. At work, I use commands like docker compose up to start the development stack (Postgres + Django), and docker compose exec web python manage.py ... to run Django commands during development. Conflicting problems: I can't pipe in input or grep output without adding -T. I don't know why, I just know it works with it, and not without it. I populate the DB with docker compose exec -T db psql -U username myproj < snapshot.sql because without the -T the input doesn't make it to psql. I also add -T when I have to grep the output, like: docker compose exec web python manage.py showmigrations | grep '[ ]'. However, when I use -T, it screws up ANSI coloring and formatting. Without -T: With -T: Question: What's the correct method? How do I properly connect STDIN & STDOUT without messing up color & formatting? -
Javascript, showing blob images
So I have this codes in my Django project. I am adding this with jQuery when I upload a file to html input tag which looks like: <input type="file" name="photo" accept="image/*" id="id_photo" multiple> JS (jQuery): ...append(`<img scr="${URL.createObjectURL(files[i])}" width="100px" height="100px">`) // files[i] comes from looping over multi-uploaded images html after uploading: <img scr="blob:http://127.0.0.1:8000/0929d4cc-972f-4f2b-b5ea-635020c47afa" width="100px" height="100px"> the blob image url (blob:http://127.0.0.1:8000/0929d4cc-972f-4f2b-b5ea-635020c47afa): So it actually shows the image in that url, but it looks like it can't identify the image in html. The question is why image is not shown on html? Thanks. -

How to simulate user intercation in Django?
I have a Django project representing an abstract retail store. Let's say it's deployed on a server and is available in the local network. I want to write another program (or extend this one?) to generate a bunch of Users, automate the process of signing up and logging in and automate their interaction with the system: make them interact with the system to order goods. So it's not just unit testing of my system but rather demonstration of how it works in real life. And I want to spawn many users to see how my system can handle many requests at once. Is there some kind of framework for that? How would you implement this? Thanks. -
Make thumbnail after ImageField save
I want to make thumbnail of an uploaded image after the Imagefield model is saved. At this moment i'm getting raise Exception error: Could not create thumbnail - is the file type valid?".

Reduce time for Loop over multiple objects to get value Django
I have a Dataframe in which a column Code is increased significantly everyday and these codes are to be converted into object description for which I am doing something like the following: product = [] beacon = [] count = [] c_start = time.time() for i, v in df["D Code"].iteritems(): product.append(Product.objects.get(short_code=v[:2]).description) #how to optimize this? beacon.append("RFID") count.append(v[-5:]) c_end = time.time() print("D Code loop time ", c_end-c_start) Now initially when the rows were less it used to work in no time but as the data increased the combined Database call for every code takes too much time. Is there any more efficient Django method to loop over a list and get the value? The df['D Code]` looks something like this: ['TRRFF.1T22AD0029', 'TRRFF.1T22AD0041', 'TRRFF.1T22AD0009', 'TRRFF.1T22AD0032', 'TRRFF.1T22AD0028', 'TRRFF.1T22AD0026', 'TRRFF.1T22AD0040', 'HTRFF.1T22AD0003', 'TRRFF.1T22AD0048', 'PPRFP.1T22AD0017', 'TRRFF.1T22AD0047', 'TRRFF.1T22AD0005', 'TRRFF.1T22AD0033', 'TRRFF.1T22AD0024', 'TRRFF.1T22AD0042'], -
