How to show django logging and error log in Cloud Run's log?
I'm using Django, uwsgi and nginx in Cloud Run. A Cloud Run service can't show django logging and error log. That's why Error Report can't use ,too. Cloud Run log is like this. This is my settings.

Filter nested serializers in Django Rest Framework
I have several nested serializers for an institution examination module. I began with term -> class -> student ->classes -> subjects -> exam_categories ->exam_subcategories -> marks. I want to filter the marks in the exam_subcategories inorder to be the marks of an indivual student. Currently each student is returning all the marks list.

React Native - Sending token to Django server
So I have this react native code that sends a token in string format, yes I've checked that var token = getCurrentUser() is a string and I've console.log it to ensure it is a JWT token as well.

i have few models namely class Alpha(models.Model): name = models.CharField() class XXX(models.Model): owner = models.ForeignKey(Alpha) class YYY(models.Model): name = models.OneToOneField(Alpha) Now while doing select_related like this test = Alpha.objects.filter(id=pk).select_related('XXX') It gives me Invalid field name(s) given in select_related, choices are YYY I understand that YYY is at OneToOne, so its showing up - but is there a way to fetch XXX also ? or should i use "prefetch_related". But i dont wanna use prefetch as its just making slow queries and meanwhile i have 7 models which needs to be select_related :( -

Django framework and chatbot development and integration
I have a question related to Python/Django/Chatbot/Web Development. I want to make a website (Django framework) with an integrated chatbot (using Rasa framework probably). Is that a good approach to use the above stacks?

This is my first attempt at working in the web development/chatbot field. -

How to pass file directly from the python file to detect macro using oletools?

CSS just won't update on CKeditor even when clearing cache
I've added CKeditor to my django website. It works, except the styling is a bit wrong. I figured I'd just grab the labels and make them white so I can see them - messing around with f12 I found that if I comment the color out here, the labels indeed turn white. Cool, no big deal, just go to editor.css and edit color: #000 to color: #fff like this: .cke_reset_all, .cke_reset_all *, .cke_reset_all a, .cke_reset_all textarea { margin: 0; padding: 0; border: 0; background: transparent; text-decoration: none; width: auto; height: auto; vertical-align: baseline; box-sizing: content-box; position: static; transition: none; border-collapse: collapse; font: normal normal normal 12px Arial, Helvetica, Tahoma, Verdana, Sans-Serif; color: #fff; text-align: left; white-space: nowrap; cursor: auto; float: none } I save, python manage.py runserver, ctrl+f5 only to find that nothing changed. I also tried collectstatic but I don't think that's relevant (0 files were modified). Inspecting the element again brings up the old css file with color: #000. Going to the network tab also reveals the same old file. What's going on here? -

Django - Multi-steps forms/split-form, how to?
quite new here. I want to create a multi-steps form. The idea is that I have a Log form that I would like to split in 4 pages(with many many skippable fields). Atm i created 1 app, with 1 model and 4 tables, 1 for each "split" and respective urls and view. My objective is to have a starting listview from where i can A)create a new log(CreateView) at page1 then, keeping the pk of the session move to page 2,3,4 and save (or save at the end of each page). At the same time i need to be able to modify it(updateView)in the same format(4 pages). How do I keep th pk to pass on? I tried to use 1 listview, with combined createview and updateviews. I also tried with formsets but I haven't been able to make much progress. What is the best way and practice to realise this multi-step form? I've read of a possible Django-tools (Wizard). Is that a viable solution or is there a better and simpler way? Thanks in advance for the help!** -

Duplicate records being created in Django Command
I'm having trouble with this function that is creating duplicate records. I have a couple pages with documents that contain a response with document as a list of records.
