django get all values in many instances?
I have a problem. products = Producto.objects.all() data = products[per_page * page: per_page * (page + 1)] And I want to get all the data from the instance, con ForeignKey and "normal" values. Example: product = <Queryset[[prod_id: 1, name: "Ferrari 1"]. [prod_id: 12, name: "Playstation 5"] [prod_id: 5, name: "Soap"]]> and in the end, what I need is something like this to be parsed to JSON and send it: [[prod_id: "Car", name: "Ferrari 1"]. [prod_id: "Console", name: "Playstation 5"] [prod_id: "Clean Acc", name: "Soap"]] -

Add users to group based on OAuth2 Role - Microsoft Azure AD - social-auth-app-django
I'm trying to use Django-Social-Auth to login to Django. I have the OAuth workflow working and I can login, but I am not part of any groups and have no permissions.. My Azure AD app has various roles configured that are mapped to AD groups.. How can I map the users role to a Django group and in turn give permissions? If I need to create a custom pipeline function, thats fine, but I cant find any reference to access the roles. Thanks. -
Is there a production ready code template to deploy a django app to aws?
I'm looking for a production-ready approach to deploy django apps to aws. The approach must be in a automated fashion and needs minimal changes when deploying for a new app. For example, let's say I have a todo list app. Now I want to deploy it to aws. I will need terraform to create the required infrastructures, and then some way to configure these infrastructure and deploy the django app there. What I want is next time when I have another app - say a blog app, I just need to change a couple of things and use the same approach I used last time to have it deployed. I have checked out a few tutorial online but none of them quite captured what I'm looking for. Using terraform for infrastructure provisioning is the norm, however for deploying django on AWS I see there are a couple of approaches. I'm not an expert in AWS so I just want something with minimal overhead and maximum reproducibility Please help me find such a template. This would help me tremendously in deploying django apps. -

Django multiple annotation for one Case-When
I'm currently trying to annotate multiple value with the same When in a Case for a Django QuerySet. Currently I have something like this: my_qs.annotate( dynamic_status_deadfish=Case( when_inactive, when_only_recently_published, when_no_published_ad, when_not_enough_booking, when_low_booking_cnt, default=default, output_field=HStoreField(), ) ) with one of those when looking like this: when_inactive = When( is_active=False, then={"status": stats_cts.INACTIVE, "reason": None}, ) when_only_recently_published = When( Q(is_old_published_ad_exists=False) & Q(is_recently_published_ads_exists=True), then={ "status": stats_cts.PENDING, "reason": OwnerStatsStatusReason.RECENTLY_SUSPENDED, }, ) when_no_published_ad = When( Q(is_old_published_ad_exists=False) & Q(is_recently_published_ads_exists=False), then={ "status": stats_cts.PENDING, "reason": OwnerStatsStatusReason.NO_BOOKABLE_TO_MODERATE, }, ) As you can see my output is a dict, or more exactly an Hstore. Ideally, I'd like one distinct annotation for status and for reason so that I don't have to deal with serialization and have an easier access to the annotation than with this HSTore One way would be to duplicate the when for status and reason as the condition are the same, but I don't like it. Something like this: when_only_recently_published = When( Q(is_old_published_ad_exists=False) & Q(is_recently_published_ads_exists=True), then=Value(stats_cts.PENDING), ) when_only_recently_published_reason = When( Q(is_old_published_ad_exists=False) & Q(is_recently_published_ads_exists=True), then=Value(OwnerStatsStatusReason.RECENTLY_SUSPENDED), ) ... my_qs.annotate( dynamic_status_deadfish=Case( when_inactive, when_only_recently_published, when_no_published_ad, when_not_enough_booking, when_low_booking_cnt, default=default, ), dynamic_status_deadfish_reason=Case( when_inactive_reason, when_only_recently_published_reason, when_no_published_ad_reason, when_not_enough_booking_reason, when_low_booking_cnt_reason, default=default_reason, ) ) Any way to somehow set two annotations in a Case or something similar ? -

How to manage azure blob storage with django in production?
I have a django app and I am using the library django-storages[azure]. When I run the django app local I can upload images via django admin to my storage container on azure. But I also have an web app with url: https://example.azurewebsites.net and I try to upload images from the mentioned url. But that doesn't work - the images are not uloaded to the storage container. So this are my azure settings in the settings.py file: DEFAULT_FILE_STORAGE = 'dierenwelzijn.custom_azure.AzureMediaStorage' STATICFILES_STORAGE = 'DierenWelzijn.custom_azure.AzureStaticStorage' STATIC_LOCATION = "static" MEDIA_LOCATION = "media" AZURE_ACCOUNT_NAME = "dier" AZURE_CUSTOM_DOMAIN = f'{AZURE_ACCOUNT_NAME}.blob.core.windows.net' STATIC_URL = f'https://{AZURE_CUSTOM_DOMAIN}/{STATIC_LOCATION}/' MEDIA_URL = f'https://{AZURE_CUSTOM_DOMAIN}/{MEDIA_LOCATION}/' Question: what I have to change so that I can upload images from the hostmachine with url: https://example.azurewebsites.net ? -
How to store the data of two different django models which share one to many relationship via a single HTML form?

Are multiple Django indices necessary?
I've a Django model that, among other fields, has time, station and variable. Nearly always, queries will be done providing the three fields - occasionally and very rarely, I might want to query using only one of them. In this case, does it matter if the index is set to models.Index(fields=["station", "time", "variable"]) or models.Index(fields=["time", "station", "variable"]) or other permutation of the three? Would it be useful to add all possible permutation or is it irrelevant? If there any performance penalty or benefit in adding all permutations? Many thanks! -
How to show the results of a many-to-many relationship backward direction via Django admin?
I have two models defined, groups and group_members, with the latter defining a many-to-many relationship to the former: class Group(models.Model): group_name = models.CharField(max_length=100, default="New Group") group_created_date = models.DateField(default=date.today) class GroupMember(models.Model): groups_joined = models.ManyToManyField(Group) email = models.EmailField(max_length=100) name = models.CharField(max_length=100) And then for my admin.py I simply have: admin.site.register(Group) admin.site.register(GroupMember) This works rather well from one side, when viewing GroupMember objects I can see and edit all the groups they belong to. However when viewing Group objects, I can not see the relationship from that side - I cannot see any members who belong to that group. What would I need to add to my admin.py to make this happen? I've been searching on how to do this but the answers either seem to convoluted and/or out of date. -

Apple Store Server Notification: Python OpenSSL certificate loading fails in "header too long"

Why do we return only a limited amount of information from a websocket event?
I'm working on implementing a real-time chat application that uses web sockets and a 3rd party application. This 3rd party application has various events that does not transmit the full message object, but rather a limited set of data. Wouldn't it be better to return the full message object, because it would greatly simplify the process of updating the client? What's happening right now is that I have to engage in complex search and update operations. I guess I am having trouble understanding this design choice because, at least in my eyes, returning the full message object shouldn't take up that much additional bandwidth. Here are some examples. API Responses Dialog (Represents chat between two people) [ { "id": 2, "created": 1704771541, "modified": 1704771541, "other_user_id": "1", "unread_count": 12, "username": "admin", "last_message": { "id": 36, "text": "f", "sent": 1704847056, "edited": 1704847056, "read": false, "sender": "1", "recipient": "2", "out": false, "sender_username": "admin" } } ] Message { "id": 36, "text": "f", "sent": 1704847056, "edited": 1704847056, "read": false, "sender": "1", "recipient": "2", "out": true, "sender_username": "admin" } Web Socket Events New Message {"msg_type": 3, "random_id": -999999, "text": "Hi …", "receiver": "2", "sender_username": "johntaylor"} Message Added {"msg_type": 8, "random_id": -999999, "db_id": 46} Unread count … -

ORA-02019 Error When Executing Queries on Remote Oracle DB in Django Application
I'm currently working on a Django application that interacts with an Oracle database. My application needs to execute SQL queries on a remote Oracle database, which is configured in the settings.py file. The SQL queries I'm trying to execute have a syntax similar to: SELECT * FROM table@source Here, source is a different database than the one currently executing the query. Both the source and target databases are Oracle databases. Despite the remote database being configured in settings.py, I encounter the following error when executing the first query: ORA-02019: connection description for remote database not found I'm looking for guidance on how to resolve this error. Here's some additional information that might be helpful: I've confirmed that the remote database is accessible outside of the Django environment. The user credentials used in settings.py have the necessary privileges. The application works fine with local database queries. Has anyone encountered a similar issue or can provide insights into what might be going wrong? Any advice on configuring Django to work seamlessly with remote Oracle databases using database links would be greatly appreciated. Thank you in advance for your help! -
In Django how to compare two texts and print a message about correctness?
I'm new to Django. In Django i would like to compare two texts and receive a message if they are the same or different. In reality these two texts are two short HTML codes. The page can reload easily, I'm only interested in the logic behind comparing the two texts (and not the use of Ajax, jQuery, JS). A text will be inserted in the front-end by the user, who will write in a div (no textarea) with contenteditable="true" which is already present in my code. I have already prepared an example text in the black panel, so I would like to compare the entire block of text (from up to ). While the other text will be contained in the backend (in a variable or something similar). Then I will click on the button and in the gray rectangle i would like to print CORRECT: the two texts are the same or ERROR: the two texts are different. Important is that i don't want to use textarea, but as already said I want to use the div with contenteditable="true" that I already have in my code. HTML {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta … -
