Django ArrayField Query issue
My model structure is as below - class DataModel(models.Model): gid = models.AutoField(primary_key=True) last_updated_time = models.DateTimeField(auto_now=True) imp_id = models.CharField(max_length=254, blank=True, null=True) members = ArrayField(models.TextField(null=True, blank=True)) The member data is stored in below format - "{"{'Memberno': '1', 'first_name': 'John', 'last_name': 'Dow', 'education_type': '','FamilyMembers': []}"}" How do I filter for first_name similar to 'John'? My filter query that I tried was - models.DataModel.objects.exclude(members__icontains='{}') But this was for exclude. Can somebody please help me filter for first_name? -

Get a django queryset that includes data from 5 linked models
I have 5 models that are linked with foreign keys like this: Section (Registration.section) ^ 1 | v ∞ Registration < ∞ --- 1 > Event (Registration.event) ^ ∞ | v 1 User (Registration.user, Profile.user) ^ 1 | v 1 Profile From these linked models, I am trying to display the data in a table like this: | ID | Other Profile fields | Section1 | Section2 | SectionN | |---------------|-------------------------|------------------------------|-----------------------------|----------| | User.username | e.g. User.profile.grade | Registration.objects.get( | Registration.objects.get( | | section=Section1, | section=Section1, | | user=user_from_this_row | user=user_from_this_row | | ).event | ).event | Where every user has a distinct row. What I can't figure out how to do efficiently is get the Registration(s) for each Section. I CAN do this by manually manipulating the data in python with dictionaries and loops etc, but this is so inefficient that my server times out before it can complete the process if the User list is too large. What queryset structure to I need to create to be able to output the data like this in a template? Each section will only have one registration object per user: class Registration(models.Model): event = models.ForeignKey(Event, on_delete=models.CASCADE) user = models.ForeignKey(User, on_delete=models.CASCADE) section = … -
AWS Elastic Beanstalk: WSGI path incorrect?
I'm attempting to deploy my first application to EB and am following along with this turorial: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html Unfortunately, I'm still getting a 502 error when deploying the final app. I'm confused because I've followed the directions to the tee. I'm getting the following error ImportError: Failed to find application, did you mean 'ebdjango/wsgi:application'? I'm not sure what this means. Per the instructions, I edited the django.config file to include this text: option_settings: aws:elasticbeanstalk:container:python: WSGIPath: ebdjango/wsgi.py This appears to match my file structure: - ebdjango -.ebextensions - django.config - .elasticbeanstalk - ebdjango - settings.py - urls.py - wsgi.py - manage.py - requirements.txt So the config file is set up correctly, right? I'm running Python 3.7 and Django 2.2. I know that EB searches for application.py, and I thought the config file is supposed to point the server towards my custom app? What am I missing here? EDIT: I'm also getting this error: ModuleNotFoundError: No module named 'ebdjango/wsgi' Is something off about my file structure? -
Implementing chat in Django application
I am a beginner in Django and I am trying to implement chatting in my Django app. I got 3 questions on how to approach this. 1. I see that people recommend to do this using Django Channels but what are the downsides to just using a database? 2. The tutorials on Channels seem to be on how to create a chat room. However I actually want the chat to be not in rooms but rather between users (I am using the default User model btw). Can anyone recommend a tutorial on how to do that? 3. In the official Django documentation JS is used too but I am not too familiar with it. So how much JS do I need to know to implement the chat? -
Capture web camera image and upload database using django
I am working on a form where in I am taking the user details like Name, email phone etc. In the same form once all the data is provided, user needs to click on Take photo button, camera gets initiated and I am able to capture the image and display in img tag in the html. Once this all is done, User needs to click on save button. All of these data including the image needs to get saved in the database/models created in backend. I have set my media and static file locations correctly. I am stuck in saving the image.

Python Django App Design change on deploy to server
I recently uploaded my Django App to the server (Digital Ocean). The functionality is okay as in my local project on my computer, but the design (css style) of the Admin Interface has changed drastically in a lot of elements of the change_list and change_form templates. I‘ve checked and made sure that the templates of my local Django and Suit files are the same as they of the server, but it is still not the same design. Does anyone has experience with that? -

Django - update ForeignKey when new object is created
I am trying to update my Foreign Key when the image is added to the database, just simply to tag the image if height is greater then width and vice versa. To do so I am trying to override the save method but I dont know how to do it exactly. models: from PIL import Image class PhotoDimensionsCategory(models.Model): photo_dim_category = models.CharField(max_length=250) class ImageInGallery(models.Model): image = models.ImageField(upload_to='photos/') gallery_dim = models.ForeignKey(PhotoDimensionsCategory, on_delete=models.CASCADE) def save(self, *args, **kwargs): super().save(*args, **kwargs) img = Image.open(self.image.path) on_height = PhotoDimensionsCategory.objects.get(photo_dim_category='on_height') on_width = PhotoDimensionsCategory.objects.get(photo_dim_category='on_width') is_new = not self.pk if img.height > img.width and is_new: # set the gallery_dim to on_height else # set the gallery_dim to on_width I tried few things, but it ended in errors. Any ideas. Thanks. -
Utilizing JQuery, AJAX and Django to have a form with chained dropdowns and add/delete form row functionality
As the title suggests i am building a template that utilizes a formset. The form has dropdown menus and it's options are loaded with ajax from a database table. As the user selects an option from first dropdown the second dropdown populates it's options from database using ajax. Total of 5 dropdowns that are linked. Everything works smoothly to this point with the django part and javascript part. I have also implemented a add/delete form functionality following a tutorial on the internet and the page successfully adds/removes forms as needed. However, when a new form is added the dependent dropdown functionality is not working for the new form. I realize this is due to the fact that the javascript code that triggers to populate the dropdown menus is listening for the change in form elements with specific id's. As a solutions (a bad one) i have duplicated the javascript codes that populate the menus and changed the id's form the form elements the code listens to since the django form management change the id following a pattern. It did not work and the form is showing strange behavior. When a new form is added, the selection from the dropdown menu … -

Override result serializer celery chord
I am using Celery chords to structure parallel AI processing of large document page content. Because this is a single use function with no public signature, I am pickling the objects to distribute and reaggregate.

Moving a django postgres database to a new server leads to InconsistentMigrationHistory
I have an database dump file of my PostgreSQL database that was created by pg_dump. I transfer this file to a new server. I also transferred all the relevant models.py files to this never server. I used the following command to load in all the data on the new server. gunzip -c dump_file | psql -p port db_name db_user I configured Django to access this database and I can query the data using manage.py shell_plus. For eaxmple, I can run Images.objects.all().count()which returns the correct number, i.e. the same number of image objects as were present on the old server. Considering this is a different server, it does not contain any of the original migration files. I used ./manage.py makemigrations to create the migrations files. This appears to work properly and migration files are created for each of my installed_apps. Next, I run ./manage.py migrate. This leads to the following error: django.db.migrations.exceptions.InconsistentMigrationHistory: Migration shapes.0001_initial is applied before its dependency bsdfs.0002_auto_20200527_1647 on database 'default'. All the answer on SO say to simply uncomment shapes from the installed_apps list, but this does not work because this leads to the following error when I'm importing it in the models.py.

How to control JWT access token based on regular payment status
I'm trying to start a subscription service for my django API. I want to control access to the API with JWT token depending on the payment of customers. If customers pay a fixed price regularly once a month, they can keep using the API. But if they fail to pay, they lose the access next month. What is the best way to implement this behavior? I come up with the following options, but I'm not sure if these are proper or not. -Issue an access token without expiration. The API itself checks the payment status and stops the service if not paid. -Issue a new access token with 1 month expiration every time the customer pay for it. The customer has to update token once a month to keep using the API, and then this is troublesome. Please let me know if there are any better ways. -
How do I convince JsonResponse to serialize a custom class?
I'm using Django 3.0.6 with Python 3.7. My views/controllers return a JsonResponse, like that: return JsonResponse({ 'My IP string': champion.ip_string, 'Chiefdom full name': chiefdom.FullName(), 'Chiefdom': chiefdom, # This will raise an exception }) I would like to upgrade the Chiefdom class to behave nicely with JsonResponse. The most obvious way to do that to me would be to override a method that JsonResponse is going to call to serialise this (I guess? It has to, come on…), but… I haven't been able to find any information at all regarding that. The whole point of this question is NOT modifying the VIEW. Only modify the Chiefdom class itself, in a way that then JsonResponse suddenly decides that "oh well now it is indeed serialisable". I could only find information that involves modifying the view itself, or stuff even more convoluted. There's tons and tons of irrelevant information, and if what I'm searching for is there somewhere, it was buried under piles of other stuff. -

Django, let user build his own table and data structure
got an hard question maybe, can't find anything apparently on google, still searching for it. In any case i'm trying to build up a form with about 40 fields. - 20 of these fields are simple CharText fields - 10 of these fields are simple DateTime fields - 10 remaining fields are my dilemma. For these last 10 field id like to let the user who's compiling the form, the possibility to: - decide the structure of the table ( like: 3 columns.
