Delete Heroku migrations
I read advices how to delete migrations but I don't understand what I'm doing and it's not working for me. History. One day I had an issue when I added or renamed a model fields locally. So I was tired with that issue and I deleted all migrations and migrate again. And all was OK. But I remember that I will have a big problem when I will deploy on Heroku. So the days are gone. And now it happened. :((( I make migrations, migrate to a server database. Pushed my code, but.. it wrote me: relation "accounts_goal" does not exist LINE 1: SELECT COUNT(*) AS "__count" FROM "accounts_goal" I understand it happened because locally I have 0001 and 0002 migrations, but on the server there are 0012 and etc. migrations. I think I need to delete all old migrations on the server. But I don't know how to do that. Help me please! Thank you) -

How to fix error "The view app.views.uploadform didn't return an HttpResponse object. It returned None instead."?
So I have a form in a html document and I'm trying to use it to add a new item to my django database.

Nested for loop in html using django to display information from 2 different models
I have a model called Section and a model called SectionInfo. Section has one field and that's name. A user will create a section by giving it a name. SectionInfo has a foreign key section_name which links it to the Section model. I have a few other fields inside SectionInfo such as things like detail, date_created, etc. What I am trying to accomplish here is using a for loop to display section names that have already been created inside or above some cards that I have set up in an html template. Then I want to use a nested loop to gather the data that is tied to that section name which is what the user inputs in for the SectionInfo model. I am able to display the section names correctly, but the issue im having is in the loop inside that loop. The same detail link is being displayed in every section that was made. Information should only be displayed in the chosen section for which it was made. Here is a bit of code to help you understand what I am trying to accomplish. {% load bootstrap5 %} {% load crispy_forms_tags %} {% load static %} {% block … -
When reversing a Django migration with AddField, can the newly column renamed undeleted by Django?
As a proof of concept, I made these two migrations in the simplest possible Django app, polls.

Why will only the top form (in order in Django view) work while the one under it will not?
I have a Django view with two Django forms. Both of them were previously working. Now whichever comes first in the order of code (on top) works.

Prevent celery from running my Django app threads
I have a Django app and I am using celery (with redis) for running processing tasks in the background. In addition, I have a python thread which runs some periodic checks as part of my Django app. Surprisingly, when I am starting celery I see my thread is also running as part of celery. I would like to prevent this behavior and have only one instance of my thread and have it as part of my Django app. How can I prevent it from running in celery? I tested it on a newly created app and see the exact same behavior: settings.py: ...

DM Messages not lining up
Social Media Platform: I am trying to get the image to line up above the sent message as you would have it in most standard DMs: https://i.stack.imgur.com/vyO2b.png But for some reason, the text attached to the image proceeds to layer itself beside the image rather than below the image, as shown in the screenshot below. When I add float: right; to my CSS the image and the text layer horizontally in a strange manner: Not lining up Ideally, the image should be on the same side as the texts from the person who sent the image and should be just above the message that was attached to the image (as is commonplace).

GUI library in Python to collapse adjustable shapes such as rectangles?
I'm new to Python, and am currently working on web development in Django. I need to have an interface on this website that allows a user to dynamically adjust a rectangular shape that displays this adjustment to them on the website in real time. Does anyone know a way to do this using other Python libraries, and how easily those libraries can be integrated into a Django project? Pretty much I need a way to display to the user a rectangle that they can drag and drop the lengths of on the screen as they desire. Very similar to the MS Word shape drawing tools where the user can pick the edge of and expand or collapse. I have explored different libraries in Python, and have found nothing concrete to do this. Any avenues for exploration would be appreciated. -

How does Django know the path to my database?

For SQLite, it’s the full path to the database file. When specifying the path, … -
How do I create a temporary link to an image in Django?
I'm writing a REST API. Users should be able to upload an image and view it. That part is easy, the images get saved to the media root, and serving them is handled separately by NGINX on /media/. The problem is that the user needs to be able to generate a temporary link to their image. It can't be a simple redirect, because what's the point of a temporary link if the end user gets redirected to a permanent link? Is there a way in Django to redirect the request on the backend, fetch the image, and return it to the user on the same URL? If not, what's the proper way to do it? I've looked through Google for some 30 minutes, and couldn't find anything. I'm sorry if it's obvious and my search queries were just wrong. -
