Django app on Windows Server 2012 - HTTP Error 500.0 - The FastCGI process exited unexpectedly
I setup a django "hello world" app IIS (Windows Server 2012). The application is run successfully using the Django web server. However, when I tried to install in on IIS (following the instructions provided here) I get an HTTP 500 error with the message "python.exe - The FastCGI process exited unexpectedly". I have seen numerous related posts on stackoverflow, but nothing seems to work for me. Based on the guidance I have checked file permissions on both the app and virtual environment folder but they in my opinion this should not be the issue as the users IUSR and IIS_IUSRS can Read & execute, Read and List folder contents. I have tried also to run wfastcgi-enable based on the instructions provided by this post but I get the error "ensure your user has sufficient privileges and try again". Please note that I tried running it both from an "elevated" command line and also power shell with no results. I have reinstalled python to make sure it is installed for "all users" (as suggested by this post) but I get an error "0x80070659 - This installation is forbidden by system policy". I looked in the Event viewer but I could not … -

django app for loop: views.py or frontend?
I am building a django app which has a list of words. The app now tells the user the first word of the list via a speech function. Then the user can record an audio of a word he sais. This word gets turned into a string in the frontend. Now I want to compare the the word from the user with the first string of a second list that has the same amount of characters as the first list. And this whole process should be repeated with all characters of the first list. Can I do this kind of loop in my views.py or do I have to do it in the frontend? -
Is Django supposed to get so slow with around 250 000 model's objects?
I am doing some small project but with around 250 000 model's objects. I have my car model and I am importing data from external json. I talked with some people and they told me that 250 000 objects in django is not a big amount and it won't have much impact on performance. Loading up to models this data from json is takin around 5 - 10 min and I don't mind that. But, right now If I make any changes to the website (locally) while running runserver I have to wait around 1 minute (on macbook pro 2020 (not M1)). And it is pretty annoying. I ran command python -v manage.py check and apparently django.db.models.sql.compiler takes this whole time. I am wondering, if my approach with models is wrong, or it is normal with SQL Light? Or maybe I could safely turn off this check? Or I got wrong informations and workflow with this many model's object is totally wrong? -

Django - how can i call a model as a string?
I'm building a DRF api endpoint that should render some json data from my database. In my view, the name of the model to query to render the data is not fixed, it depends on what query does the user perform. So i have this: collection = 'MY_MODEL' queryset = collection.objects.filter(**filters) But this will give the following error: 'str' object has no attribute 'objects' This will work instead: queryset = MY_MODEL.objects.filter(**filters) Is there any way to get around this? -

How to workout a logic, so that a user can send me a gift(point based) if they really like my blog? - In Django
hello guys/girls I am trying to figure out a logic similar to how we see in some social apps where the user is able to send gift points to the creator by paying some money. I am thinking of having a similar setup in my blog website, where the user can send me gifts if they find the blog useful. What's the best way to implement this? I want to store these information when the user sends a gift- the sender info (Only logged in users can send), for which blog post, how much points (There will be gift options like 10, 20, 50 points) and at what time. I am having trouble thinking about the logic as I have never done anything like this before. Should I go with the content types considering the future, if I plan to have vlogs section along with the current blogs for easier integration? Will using content type affect the performance greatly? Thanks -
django_crontab not working on production docker
I'm trying to run a scheduled script using django_crontab twice a day. I have tested it locally on ubuntu 18 and it works. However, when I'm trying to run it on the server (python Docker image that runs Django project on remote Ubuntu server) here is my code: setting.py: INSTALLED_APPS = ( . . 'django_crontab', . . . ) RONJOBS = [ ('25 8,21 * * *', 'appname.folder.file.start') ] I executed cron by: $ python manage.py crontab add . and see the active job: $ python manage.py crontab show f95300a5599dc7687ac79ab51c8bb33c -> ('13 9,21 * * *', 'appname.folder.file.start') def start(): logger.info(" process begins!") do_something() Note The function 'start' was tested in the production server and it works. I also tried to map the chronjob logs by adding path to the CRONJOB at setting.py: ('25 8,21 * * *', 'appname.folder.file.start','>> /Logs/crontab.log') but the file crontab.log wasn't created. Any suggestions? Thanks! -
