django model property depended on request.session value
My models have validation_range field. Very complex. For simplicity I will show example - it may looks stupid but this is for explanation only - so don't look at the model itself, please class Person(models.Model): validity_range=DateTimeRangeField(default=(None,None)) class PersonData(models.Model): person = models.ForeignKey(Person, on_delete=models.RESTRICT) first_name = models.CharField(max_length=255) last_name =models.CharField(max_length=255) validity_range=DateTimeRangeField(default=(None,None)) And now Person can have a two names: E.g. Miss Eva Smith born 1.1.1980 gets married 22.03.2022 and becomes Mrs. Eva Novak. (for simplicity I omit time part of validity_range) So datas look like: Person{id:1,validity_range:(1980-01-01,None)} PersonData{id:1,person_id:1,first_name:'Eva',last_name:'Smith',validity_range:[1980-01-01,2022-03-22)} PersonData{id:2,person_id:1,first_name:'Eva',last_name:'Novak',validity_range:[2022-03-22,None)} I preserve context_date in request.session['context_date']. And I will show Eva's full name dependent of request.session['context_date'] def index(request): person = Person.objects.get(pk=1) context ={ 'person' : person, 'context_date' : request.session.get('context_date') } html_template = loader.get_template('index.html') return HttpResponse(html_template.render(context, request)) html: Context_date is: {{ context_date }} At that date Person no {{ person.id }} was called {{ person.person_data.first_name }} {{ person.person_data.last_name }} Of course this is wrong, because person_data is a set not a object. I thought to make a property in model: class Person(models.Model): validity_range=DateTimeRangeField(default=(None,None)) @property def first_name(self, date): try: person_data =PersonData.objects.get(validation_range__contains=date) #We can assume, that validation_ranges don't overlaps (database constraint) return person_data.first_name except PersonData.DoesNotExist: return None #oups - there's no persondata in that date! But how pass parameter … -
Partitioned tables in psql with django
I partitioned a table in Postgres with Django. All was fine, the insertion went good but when I try to make a query the response is just a field from the original table. So my question is: How is right way to make query in partitioned table in Django? -
Simple blog django application deployed using Heroku/PostgreSQL database utilizing Tinymce image plugin for textarea - Not Working
I followed these simple instructions to replace a text area in django with an HTMLField from tinymce. You simply install tinymce and add it to installed apps in your settings file and then import tinymce in your models file and use the HTMLField() where appropriate. https://www.youtube.com/watch?v=qUOPn5xi0oA My text area is editable as expected using tinymce. However, I wanted to add the capability to add pictures to the blog post (this is mentioned in the second half of the video). When I follow these instructions my editable textarea does not include a file uploader option. https://www.tiny.cloud/docs/plugins/opensource/image/ JS snippet I copied from tinymce: <script> tinymce.init({ selector: 'textarea#file-picker', plugins: 'image code', toolbar: 'undo redo | link image | code', /* enable title field in the Image dialog*/ image_title: true, /* enable automatic uploads of images represented by blob or data URIs*/ automatic_uploads: true, /* URL of our upload handler (for more details check: https://www.tiny.cloud/docs/configure/file-image-upload/#images_upload_url) images_upload_url: 'postAcceptor.php', here we add custom filepicker only to Image dialog */ file_picker_types: 'image', /* and here's our custom image picker*/ file_picker_callback: function (cb, value, meta) { var input = document.createElement('input'); input.setAttribute('type', 'file'); input.setAttribute('accept', 'image/*'); /* Note: In modern browsers input[type="file"] is functional without even adding it to the … -

Upgrading dependencies while upgrading django
so I've been tasked with upgrading a fairly large Django project with multiple apps and over 60 dependencies... the app is also a fairly old 2.0 version of Django. For the most part, I know what the main code refactors I'll have to make in terms of the actual Django code but upgrading third-party packages is what's worrying me.. its been a bit difficult to find if those packages are compatible with newer versions of Django and so I'm not sure whether to upgrade the dependencies or not. I'd appreciate any help on this process if someone has attempted it before and what they would reccomend. -

CVB with 2 forms in one template: form2 errors are not displayed
EDIT in fact form2 errors are displayed as 'form2.errors' and not 'form2.date_of_last_period.errors' Django 4.1.6 I try to implement a single CBV to manage 2 forms. I use ModelForm to define the 2 forms Inclusion and Patient. Models Inclusion and Patient are link with a one-to-one relationship (I understand I could do a single model but have to separate). I have override methods of CVB CreateView. In post methods, I test for 2 forms validity. And if not valid, call appropriate form_invalid method. In debbug (print('invalid',form.errors,form2.errors)) I see errors raised. But the form2 render to the context (context['form2'] = kwargs.get('form2', self.second_form_class())) do not content any errors.

Redis GRAPH | unable to set TTL to the node and edge created in redis graph via python
I am using redis graph in my django project to save huge number of data nodes. I am not able to set the expire time of these nodes so the redis data keeps on increasing. I do not want to set a TTL in configuration as different nodes can have different TTL. I am using django-redis==5.2.0 for intereacting with redis from django. Also i am mostly using raw graph query to save data in redis graph like "CREATE (n:label {a:1}) RETURN n" , so if there is a parameter which i can set here to set TTL it will be helpful. -

Django Firebase iOS Push Notifications
I have an iOS application where I want to add push notifications. I also setup a Django backend for the app. I want to send push notifications from the Django backend to the iOS app for specific users. I successfully setup Firebase Messaging and am receiving the push notifications on the mobile app when I create one through the FireBase dashboard. However, I am incredible confused on how I can achieve this through the backend. I am using the Django-push-notifications app from Github I have setup the settings as follows: INSTALLED_APPS = ( ... "push_notifications" ) PUSH_NOTIFICATIONS_SETTINGS = { "FCM_API_KEY": os.environ.get('FCM_API_KEY', "AAAAA"), "APNS_AUTH_KEY_PATH": "/MYkey.p8", "APNS_AUTH_KEY_ID": os.environ.get('APNS_AUTH_KEY_ID', "AAAAA"), "APNS_TEAM_ID": os.environ.get('APNS_TEAM_ID', "AAAAA"), } I don't manually use the APNS tokens. I use the FCM tokens to send a message to a specific user in the dashboard of FireBase. However, I am not aware that Firebase is using any APNS tokens (but it must I suppose). This topic just adds to the confusion since APNS tokens aren't necessarily tied to the retrieval of FCM tokens. From what I gather I should use the following code to send a message: from push_notifications.models import APNSDevice device = APNSDevice.objects.get(registration_id=apns_token) device.send_message(message={"title" : "Game Request", "body" : "Bob … -
Blank Page for React frontend (django backend) when deploying through Google Cloud Platform Nginx
Im deploying my server with nginx inside a GCP Compute Engine. The Application uses django and react. So far the Django Backend API shows allright on my domain.However, I am trying to connect to the React.js I tried : npm run build (build successful) with the following files inside my build folder (asset-manifest.json, index.html, manifest.json. static/css/main.css, static/js/main.js) sudo nano /etc/nginx/sites-available/backend server {server_name domain_name.org; location /api/ { include proxy_params; proxy_pass http://127.0.0.1:8000; } location /static/ { root /home/username/projectname/backend/static/; } location / { root /home/username/projectname/frontend/build/; try_files $uri $uri/ /index.html; } .... some ssl certicates etc ....

My usecase_assign model: class UsecaseAssign(models.Model): usecase_assign_date = models.DateTimeField(primary_key=True, auto_now_add=True) usecase = models.ForeignKey(Usecase, models.DO_NOTHING) user_email = models.ForeignKey('User', models.DO_NOTHING, db_column='user_email') usecase_role_id = models.CharField(max_length=20) if request.method=='POST' and 'delete_user' in request.POST: users = User.objects.filter(user_email=request.user) assigned_user = UsecaseAssign.objects.filter(usecase_assign_date__in=users).delete() if assigned_user: messages.success(request, "user was deleted successfully!") return HttpResponseRedirect(reverse('usecase-details', args=[ucid])) else: messages.error(request, "Some Error was occurred!") return HttpResponseRedirect(reverse('usecase-details', args=[ucid])) my template: <label class="mb-card h5" for="user_email">Assigned users:</label> {% for user in usecase_assigned %} <form action="/usecase-details/{{result.usecase_id}}" method="POST" style="display: inline !important;"> {% csrf_token %} <div class="btn-group me-2 mb-2"> <button type="button" class="btn btn-outline-danger">{{user|join:', '}}</button> <button type="submit" class="btn btn-danger" name="delete_user"> <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="currentColor" class="bi bi-file-x-fill" viewBox="0 0 16 16"> <path d="M12 0H4a2 2 0 0 0-2 2v12a2 2 0 0 0 2 2h8a2 2 0 0 0 2-2V2a2 2 0 0 0-2-2zM6.854 6.146 8 7.293l1.146-1.147a.5.5 0 1 1 .708.708L8.707 8l1.147 1.146a.5.5 0 0 1-.708.708L8 8.707 6.854 9.854a.5.5 0 0 1-.708-.708L7.293 8 6.146 6.854a.5.5 0 1 1 … -

NoSuchKey error while using digitalocean spaces and django-filebrowser-no-grappelli
I'm using django-filebrowser with DigitalOcean Spaces as the storage backend for my Django project. When I try to access the filebrowser URL to browse the files, I get the following error: NoSuchKey at /admin/filebrowser/browse/ An error occurred (NoSuchKey) when calling the ListObjects operation: Unknown I'm not sure what's causing this error and how to fix it. I've already checked the bucket name, region name, and permissions, but the error still persists. Here are some more details about my configuration: I'm using django-filebrowser version 3.12.2 and django-storages version 1.11.1. I have to set up the DEFAULT_FILE_STORAGE setting in my Django settings file to use custom-made storage class: import os from filebrowser.storage import S3BotoStorageMixin from storages.backends.s3boto3 import S3Boto3Storage class MyStorage(S3Boto3Storage, S3BotoStorageMixin): def _clean_name(self, name): return os.path.join("", os.path.normpath(name).replace('\\', '/')) def isdir(self, name): return name.endswith('/') I've set up the AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_STORAGE_BUCKET_NAME, AWS_S3_REGION_NAME, and AWS_S3_ENDPOINT_URL settings in my Django settings file to configure the S3 connection to DigitalOcean Spaces. I've granted the s3:ListBucket and s3:GetObject permissions to the IAM user that I'm using to access the bucket (file uploading from admin panel is working fine) I've set up the MEDIA_URL setting in my Django settings file to point to the public URL of the … -
Django AttributeError: type object 'Admin' has no attribute '_meta' error when creating custom user
I'm learning django and I want to have my custom user and admin object but I'm encountering an error when running server after applying my changes. I'm not sure if this is the right approach to do this so do enlighten me if I'm following the wrong approach. So I have created an app called 'core' where I want to do authentication stuff so that's where I've put my custom user models.
