Example of jqgrid with python
So I've cloned this https://bitbucket.org/romildo/django-jqgrid-demo.git as I am looking for a working example of jqgrid with django. I've been updating the code (as this seems like it was written for a version 2 of django and I'm workng on 4.1) I'm completely stumped by the lines from jqgrid import JqGrid giving me this error ModuleNotFoundError: No module named 'jqgrid' I cannot find a reference to jqgrid within pip and I cannot install one (jqgrid is not a python package) I understand that jqgrid is a javascript component around jquery but how do I get that to work in Python I have google for django-jqgrid and on youtube. None of the answers provide enough information to get a simple working example up. There seems to be an assumption that everything is installed and I'd like to understand what is required where and how to reference What am I missing? -

ImageField storage options based on settings
I am using django-storages with the Azure backend. I would like to use the local provided Django solution when running locally and the Azure storage when running in production. How would I change this based on the settings? Do I just use an IF statement below these? # local image = models.ImageField(upload_to="profile_pics", blank=True, null=True) # production image = models.ImageField(upload_to="profile_pics", blank=True, null=True, storage=AzureMediaStorage()) -
What's the diffrence bettwen timezone.now and auto_now_add parameters in DateTimeField field in Django models?
I'm writing my first Django app - blog. When creating Post model I'm asked to create publish and created fields with timezone import. publish = models.DateTimeField(default=timezone.now) created = models.DateTimeField(auto_now_add=True) It's explained that "By using auto_now_add, the date will be saved automatically when creating an object" and "timezone.now returns the current datetime in a timezone-aware format". So it seems to me that they both same job. Why not use default=timezone.now in both fields? What's the difference? It's my first question so sorry in advance if I made some mistakes. -

Django CSRF Protection GraphQL API
I do have a graphqlAPI which I use for CRUD Operations to my database. The authentication is tokenbased. So if an user wants to make cruds (mutations) to my database, it needs a valid token in order to do that. What I dont know is if my graphql API is also protected against CSRF attacks as I exempt this protection with csrf_exempt without csrf_exempt it needs a csrf token. Is there a way to ask for a valid csrf token without sending it over the frontend ? The graphql api is only used for the backend for inserting data into the database in which I cant get the csrf token over the frontend. Backend/Frontend: Django Database: Mongo Thanks -

CSS not loading on django on different settings environments

Django complex query with page load slow
I have a quiz application made with Django. I am basically loading a pretty complex query. What I am basically doing is creating a new exam with this logic: Fetch the question from the question bank (the Question model) I get a certain questions number from each subject and I use them to create a QuestionDraft so I can store and save each student result. Each QuestionDraft has the AnswerDraft which I use for storing the user answered questions (each AnswerDraft is basically a carbon copy of the question bank Answer). While I wanna load a 50-question-test everything works pretty fine but when I want to load more than that amount of question, the page is loading extremely slow. I would like to know if, based on the models and the code I post down below, there is any way to improve the efficiency of the queries and/or the loading time. models.py class QuestionSubject(models.Model): quiz_course = models.ForeignKey(QuizTheoryCourse, on_delete=models.CASCADE) name = models.CharField(max_length=200) exam_questions_num = models.IntegerField(null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Question(models.Model): id = models.CharField(max_length=7, default=generate_question_id, unique=True, primary_key=True, editable=False) question_subject = models.ForeignKey( QuestionSubject, on_delete=models.CASCADE) text = models.TextField() mark = models.IntegerField(default=1) is_published = models.BooleanField(default=True) question_bank_id = models.CharField(max_length=255, blank=True, null=True) question_topic … -
