Django admin - Allow deletion only for users in a specific group for all models
I want to allow hard deletion in the Django administration site only for members of a specific group. To achieve this, I could create a mixin where I override has_delete_permission and get_actions to check if the user is a member of the group. Then, I could use it in all admin classes. However, I have a lot of admin classes and I don't want to update all of them and to always think about adding this mixin every time I create a new one. Is there a better way to achieve the same? -

How should i create, save and open user specific checklist data in django?
I need to develop this app using Django. I have given checklist of 25 checks. This checklist is related to PCB designing. The checklist will get updated as PCB passes through different stages. Before sending PCB for manufacturing user has to complete all the checks. To avoid the error in later stages and the cost this checklist has been created. Requirement is, User need to login to the application. After login if he wants to create new project, he should be able to create new project and after creating a new project the checklist should open when he should be able to check and uncheck those 25 checks. Suppose user is working on 5 different PCB designs then he should be able to save those 5 projects individually. After login if he wants to open old project then also, he should be able to open the old project and see how many checks he has completed and how many are remaining? I am new to Django. Before 2 weeks I started learning Django. I already have created user registration and login page and stored user data in postgresql. Now my question is, how should I create or open a new … -
Local python module overrides module installed with pip
I am having issues with importing, my own, pip package named the same as a module inside a django-app. Lets say my own pip module is called: fancymodule. I then have a module-folder inside a django-app named the same: * django-project * payments * models.py * fancymodule/ * __init__.py The problem I am having, is that inside payments/models.py, I import: from fancymodule import ApiClient This is suppose to reference the fancymodule installed through pip. But is instead referencing the module inside the payments-django-app instead. If I wanted to reference the module inside the payments-django-app, in my head, this should be: from payments.fancymodule import whatever I get that from the view of payments/models.py, the import fancymodule .. will reference the module inside the folder it self of the specified name.. but can i change/fix this? FYI: Working on an old legacy project. Home someone can help. -
Is FILE_UPLOAD_DIRECTORY_PERMISSIONS required after upgrade to Django 3.1?
There was a web app on Django 2.x with no FILE_UPLOAD_DIRECTORY_PERMISSIONS and FILE_UPLOAD_PERMISSIONS. After upgrade to Django 3.1 (through 3.0) (new) user media files saved to new directories are inaccessible to users via nginx static files serving. They become accesible if I manually fix permissions with chmod -R 755 . in media directory. And I guess it will be fixed for all new files when I set FILE_UPLOAD_DIRECTORY_PERMISSIONS. The question is why it was not needed in django 2.x and how do I not miss something similar next time? Apparently, FILE_UPLOAD_DIRECTORY_PERMISSIONS is not mentioned in https://docs.djangoproject.com/en/3.1/releases/3.0/ and https://docs.djangoproject.com/en/3.1/releases/3.1/ -

Exit server terminal while after celery execution
I have successfully created a periodic task which updates each minute, in a django app. I everything is running as expected, using celery -A proj worker -B. I am aware that using celery -A proj worker -B to execute the task is not advised, however, it seems to be the only way for the task to be run periodically. I am logging on to the server using GitBash, after execution, I would like to exit GitBash with the celery tasks still being executed periodically. When I press ctrl+fn+shift it is a cold worker exit, which stops execution completely (which is not desirable). Any help? -
