Django Administration - Customize list appearance and selection of ManyToManyField keys
I have a database with 1000+ songs. I have a custom model "Schedule" that accepts songs as field. models.py from django.db import models class Song(models.Model): title = models.CharField(max_length=255) words = models.TextField() slug = models.SlugField() date = models.DateTimeField(auto_now_add=True) snippet = models.CharField(max_length=50) def __str__(self): return self.title class Schedule(models.Model): songs = models.ManyToManyField(Song) date = models.DateTimeField(auto_now_add=True) def __str__(self): return str(self.date) admin.py from django.contrib import admin from .models import Song, Schedule @admin.register(Song) class SongModel(admin.ModelAdmin): search_fields = ('title',) list_display = ('title',) list_per_page = 100 @admin.register(Schedule) class ScheduleModel(admin.ModelAdmin): search_fields = ('date',) list_display = ('date',) list_per_page = 100 I want to be able to add any song I want to a schedule, but it is difficult do to so through the default list in the Django-Administration, which looks like this. I have to scroll and CTRL+select each one of them, then add them. I'd like something more more practical where I can select, search, etc. What are my options? I don't know where to start looking. -
Setting a ImageField initial value
I have a form as below: class FileChangeForm(ModelForm): the_image = forms.ImageField() class Meta: model = ... fields = [ 'fields', 'the_image' ] I want to set the image in the form init, I tried to do a couple of things but nothing seems to populate the HTML form with an initial value using a bytes array.

AWS Boto3: Access denied while running in Django Server
My textract code is successfully working when running in its own file, however, when I try to run it in my django development server, the authentication stops working. I recieve this exception: botocore.errorfactory.InvalidS3ObjectException: An error occurred (InvalidS3ObjectException) when calling the StartDocumentAnalysis operation: Unable to get object metadata from S3. Check object key, region and/or access permissions. So far, I have tried: Passing credentials as parameters in the boto.client() method Assuming a role, rather than using IAM user credentials Verified the object key, and region Checked my firewall Here is my authentication format: client = boto3.client('sts', region_name="us-east-2") # Assumes a role. response = client.assume_role( RoleArn='arn:aws:iam::xxx:role/xxx/xxx', RoleSessionName = 'djangoBoto3', DurationSeconds = 3600, ) textract = boto3.client( # Instantiate the textract client "textract", region_name="us-east-2", aws_access_key_id = response['Credentials']['AccessKeyId'], aws_secret_access_key = response['Credentials']['SecretAccessKey'], aws_session_token = response['Credentials']['SessionToken'] ) Here is how I am calling the textract function response = textract.start_document_analysis( DocumentLocation = { 'S3Object':{ 'Bucket': bucket, 'Name': key, } }, FeatureTypes = ['TABLES', 'FORMS'] ) Some AWS API calls are working within Django. For example I can upload files to S3 buckets. This leads me to suspect maybe this could be a signature issue. I read here Amazon Docs that certain AWS operations such as S3 can … -
Django and a Database with write-Instance + Multiple Read Replicas -- running Celery jobs
I have a django app running in production. Its database has main write instance and a few read replicas. I use DATABASE_ROUTERS to route between the write instance and the read replicas based on whether I need to read or write. I encountered a situation where I have to do some async processing on an object due to a user request. The order of actions is: User submits a request via HTTPS/REST. The view creates an Object and saves it to the DB. Trigger a celery job to process the object outside of the request-response cycle and passing the object ID to it. Sending an OK response to the request. Now, the celery job may kick in in 10 ms or 10 minutes depending on the queue. When it finally tuns, the celery job first tries to load the object based on the ID provided. Initially I had issues doing a my_obj = MyModel.objects.get(pk=given_id) because the read replica would be used at this point, if the queue is empty and the celery job runs immediately after being triggered, the object may have not propagated to the read-replicas yet. I resolved that issue by replacing my_obj = MyModel.objects.get(pk=given_id) with my_obj = … -

Django: Associate a social account to currently logged on user
Basically: I want a user to be able to signup with their email and once authenticated they should be able to add a social account and for the social account to be linked(associated) to that currently authenticated user. The link should happen even if the emails are different (between user and social account). A social account cant be linked to more than one user. I am not really interested in user FB account data but rather I want access to their page(s) metrics. I am using Django with Django rest Framework.

Django Rest Framework admin panel not using custom User Manager
I have implemented a CustomUser and CustomUserManager in my DRF app. The tutorials I have followed are this one and this one, which are nearly identical approaches to creating a custom user and custom user manager. I placed a print statement in the create_user and create_superuser methods of the custom user manager to check it was being used correctly. class MyUserManager(BaseUserManager): def create_user(self, email, password, **extra_fields): print("manager used") ... When I use the command python manage.py addsuperuser, the print statement runs, great. When I use the built-in admin panel of the DRF framework localhost:8000/admin to create a new admin or regular user, the statement doesn't run, however, the user is created without error. As far as I can see, the implementation is meant to have the admin panel use the new customer user manager, but that doesn't seem to be the case. What have I done wrong? -

Filtering django admin inline - limit the choices list
Given my inline admin: class TestInlineAdmin(admin.TabularInline): model = Test.questions.through extra = 0 and then class QuestionAdmin(admin.ModelAdmin): inlines = [TestInlineAdmin, ] Test model has question field which is ManyToMany. And i am normally able to edit the question list directly from Test model. But i want to be able to choose the Tests from inline admin within QuestionAdmin (so, in reverse). This works. But i need to filter the Test objects in this inline, so the list of choices would show me only Test.objects.filter(applicable=False). I've tried to use get_queryset, but this seems to have no effect on the choice list, it's only filtering the the actual referenced items in inline, but the list of choices for the new item always shows me the complete unfiltered queryset for Test model. Overriding formfield_for_manytomany does not work in inline - it's not executed at all. Would it be possible somehow with formfield_overrides? Or, as i believe the only way would be to customize the inline form? -

jQuery $.load Not Executing

In the image linked below, the clicking the arrow buttons should make the green or red number change. The number does not change when the arrow is clicked, but it does change when I reload the entire page. https://i.stack.imgur.com/T26wn.png -

Cannot test equality of rest_framework.utils.serializer_helpers.ReturnList while testing
Being new to django rest framework, I tried to make a simple unittest to test a simple search api endpoint. However, when I try to test the equality of the response data and the expected result, assertEqual always returns False when in fact it's the same result. Here is the test class # imports... client = APIClient() User = get_user_model() class SearchTest(APITestCase): def setUp(self): landlord = User.objects.create_user("a@a.com", "testuser", "firstname", "lastname", "password") self.test1_listing = Listing.objects.create(name="test1", place="Pinekarta", adult_guests=2, landlord=landlord) self.test2_listing = Listing.objects.create(name="test2", place="Pinekarta", landlord=landlord) self.test3_listing = Listing.objects.create(name="test3", place="New Bannkarta", landlord=landlord) def test_valid_place(self): response = client.get(reverse('api-search', kwargs={'place': "New Bannkarta"}), format='json') result = DetailedListingSerializer(instance=[self.test3_listing], many=True).data print(type(result)) print(type(response.data)) self.assertEqual(response.data, result) Although result and response.data have the same type and their string representation is the same, for some reason assertEqual always fails. self.assertEqual(response.data, result) AssertionError: [Orde[690 chars]ber_of_comments', 0), ('comments', []), ('avg_rating', None)])] != [Orde[690 chars]ber_of_comments', 0), ('comments', []), ('avg_rating', None)])]
