How to Override Django ManyRelatedManager Methods and Enforce Validations
I have the following two models that have a Many-to-Many (m2m) relationship. I want to implement validation rules when creating a relationship, particularly when the Field object is controlled. class Category(models.Model): name = models.CharField(max_length=50, unique=True) slug = models.SlugField(max_length=50, unique=True, editable=False) fields = models.ManyToManyField("Field", related_name="categories") class Field(models.Model): controller = models.ForeignKey( "self", models.CASCADE, related_name="dependents", null=True, blank=True, ) label = models.CharField(max_length=50) name = models.CharField(max_length=50) When creating a relationship between a Category and a Field objects via the add() method, I would like to validate that, for a controlled field, the controller field must already be associated with the category. When creating via the set(), I would like to validate for any controlled field in the list, the controller field must also be in the list, OR is already associated with the category. # Category category = Category.objects.create(name="Cars", slug="cars") # Fields brand_field = Field.objects.create(name="brand", label="Brand") model_field = Field.objects.create(name="model", label="Model", controller=brand_field) # controller should already be associated or raises an exception category.fields.add(model_field) # Controller must be inclded in the list as well, # OR already associated, or raise an exception category.fields.set([model_field]) Where can I enforce this constraints? I'm thinking of overriding ManyRelatedManager's add() and set() methods but I do not understand how they're coupled to … -
Image uploaded via CKEditor in Django extends beyond the div
I'm working on my very first Django project, a blog, and I'm almost done with it. However, I've got this quirky issue: the images I upload through CKEditor spill out of the div they're supposed to stay in. Any ideas on how to fix that? This is how I upload the image: I understand that when uploading, I am able to set the image size. However, I would like the image width to be 100% of the div automatically, while maintaining the original image's aspect ratio for the height. This is how it is displayed: Here is the template: {% extends "mainapp/base.html" %} {% block content %} <div id="main-container"> <div id="second-container"> {% if article.article_image %} <img src="{{article.article_image.url }}" id="article-image"> {% endif %} <p>Published: {{article.publication_date}} {% if article.last_edit_date != None %} Last edit: {{article.last_edit_date}} {% endif %} </p> <h1>{{article.title}}</h1> <p>{{article.body|safe}}</p> {% if user.is_superuser %} <a href="{%url 'mainapp:edit_article' article.id %}"><button type="button">Edit</button></a> <a href="{%url 'mainapp:delete_article' article.id %}"><button type="button">Delete</button></a> {% endif %} </div> <br> <br> <div id="second-container"> <h3>Comments section</h3> {% for comment in comments %} <p> {{comment.publication_date}} {% if comment.author == "ravdar (op)" %} <span style="color: orangered; font-weight: bold;">{{ comment.author }}</span> {% else %} {{ comment.author }} {% endif %} <p>{{comment.text}}</p> {% endfor %} … -
Django & Djoser - AttributeError: 'NoneType' object has no attribute 'is_active' when registering a new user

Website fails to load after db data upload
The website I am working with is based on django v3.2.19 with a mysql v8.0.32 back end, in a windows 10 environment. The database had limited data, so I updated the db from a backup of the same db set up on a different system (AWS, linux). The website, up until an hour ago was up and running. After the data upload, I was unable to start the server with 'python manage.py runserver'.

currently am working on a django project that connect to an informix database using (CSDK/ODBC) and the connection is established correctly, but when i try inserting data in darabic language i get this error: "21005 Inexact character conversion during translation".

Change logic for admin views in django
I am creating a website in pure django where I have the following model. class GoodsDetails(models.Model): serial_number = models.CharField(max_length=100) goods_description = models.CharField(max_length=100) quantity = models.CharField(max_length=100) gross_weight = models.CharField(max_length=100) is_active = models.BooleanField() def __str__(self): return f"{self.serial_number}" I have registered the model in the administration and I want to show all the model instances to the superuser but to non-superusers, I want to show only those instances where is_active = False. How can this be achieved in django administration? I researched about it and think that I should create a custom permission for this job. However, I think that modifying the admin views logic would be better because in this case, changing the ORM query a bit will get the job done. Any other approaches are also welcome. Thank you for your suggestions and/or solutions :) -

Django gives Forbidden: 403 for POST request with my live react website but not when using postman
When I try to send the request given below from my react website, Django returns a 403 error. axios.post(apiUrl, formData, { headers: { 'Content-Type': 'multipart/form-data' } }).then(response => { console.log('Attendance uploaded successfully:', data); }).catch(error => { console.error('Error uploading attendance:', error); }); I get Forbidden (403) error. But when I run the code from my local server (localhost:3000), it does not give an error, and return 200. Same for Postman, it does not return any error and returns 200. My settings.py file looks like: ALLOWED_HOSTS = ['domain', '10.17.51.139', 'localhost', '127.0.0.1'] CORS_ALLOW_ALL_ORIGINS = True CSRF_TRUSTED_ORIGINS=['https://domain', 'http://domain', 'http://10.17.51.139', 'http://localhost:3000'] Can anyone explain why? I tried including cookies in the header, but that was of no use, I also applied the @csrf_exempt tag in my view, but same error again. I also tried to remove middleware but still no difference GET requests do not give any trouble and return 200 for live website as well. Can someone explain why this is happening and suggest a solution -

Razorpay API Request Error - Emojis Causing Internal Server Error (500) and Bad Request (400)
I'm encountering an issue with Razorpay API requests in my web application.

Django Form List Value Multiple Choice in Form based on values in other fields in same form
I have a problem in Django Form Basically I am developing a Form which shows the following information: Date From Date To Client Select Jobs to be reviewed: Now i have a model where the jobs are linked to a clients and the jobs have a date when they were created and when they were terminated. I would like that in the form as soon as the user inputs the date from of the review and Date To of the review and the client in question by default a list of jobs will be displayed for the user to select. The list of jobs is based between the active jobs during the period selected and also the client. Is there a way to achieve this dynamically in the same form in Django ? Any ideas how to achieve it? I tried using ChainedManyToManyField so that based on the client selected in same form the list of jobs would be displayed and I succeeded. The problem is that i do not know how to also filter by the job creation date and job terminated date ? -
Celery' pytest fixtures don't work as expected during http request
everyone. Probably I'm missing somethig on how to use celery' pytest fixtures during a test that involves a task execution during an http request. Celery' docs that shows the pytest integration: https://docs.celeryq.dev/en/v5.3.4/userguide/testing.html#pytest Using 'celery_session_app' and 'celery_session_worker' fixtures I can directly call the task and use wait() or get() to wait for task execution. Sample code for this case: from django.core import mail from django.test import TestCase from polls.tasks import task_send_mail @pytest.mark.usefixtures('celery_session_app') @pytest.mark.usefixtures('celery_session_worker') class SendMailTestCase(TestCase): def test_send_mail(self): task: AsyncResult = task_send_mail.delay( email_address='mail@mail.org.br', message='Hello' ) # waits for task execution that just sends a simple mail using # from django.core.mail import send_mail task.get() # it passes because the code waited for mail send self.assertEqual(len(mail.outbox), 1) However, if I call the same task inside a django view, the task is executed assynchronous and the test fails because the assert is tested before the mail is sent. # view from rest_framework import serializers from rest_framework.generics import ListAPIView from rest_framework.response import Response from django.contrib.auth.models import Group from polls.tasks import task_send_mail class GroupSerializer(serializers.ModelSerializer): class Meta: model = Group fields = ['__all__'] class GroupView(ListAPIView): http_method_names = ["get"] queryset = Group.objects.all() serializer_class = GroupSerializer def get(self, request, *args, **kwargs): # task is sent to async execution task = … -
