How to populate auth.groups and auth.group_permissions tables with initial data in Django project
Context I am using PostgreSQL. I would like to immediately populate the auth.groups and auth.group_permissions tables, after the very first migration of my project. So, after I have set up these tables the way I want them, I dump them by running python manage.py dumpdata auth.groups auth.group_permissions > core/fixtures/initial_data.json The resulting file is this [ { "model": "auth.group", "pk": 1, "fields": { "name": "Admin", "permissions": [ 29, 31, 32, 33, 34, 35, 36 ] } }, { "model": "auth.group", "pk": 2, "fields": { "name": "Operators", "permissions": [ 42, 43, 44, 39, 40 ] } }, { "model": "auth.group_permissions", "pk": 12, "fields": { "group": 1, "permission": 32 } }, { "model": "auth.group_permissions", "pk": 13, "fields": { "group": 1, "permission": 33 } }, { "model": "auth.group_permissions", "pk": 14, "fields": { "group": 1, "permission": 34 } }, { "model": "auth.group_permissions", "pk": 15, "fields": { "group": 1, "permission": 35 } }, { "model": "auth.group_permissions", "pk": 16, "fields": { "group": 1, "permission": 36 } }, { "model": "auth.group_permissions", "pk": 17, "fields": { "group": 1, "permission": 29 } }, { "model": "auth.group_permissions", "pk": 18, "fields": { "group": 1, "permission": 31 } }, { "model": "auth.group_permissions", "pk": 19, "fields": { "group": 2, "permission": 39 } }, { … -

Runtime model generation in Django or other languages
I'm asking this question for hearing about advice and having an idea about the possibility of this type work. Not asking for any code help, just advice, and a little leading would be helpful, if it is still the wrong place to ask this question, sorry about that. I would like to build an application that lets users upload a CSV or excel file and generate a SQL table at the backend at that time and store data into the table. Then print the loaded data in UI. I did it before in a terrible and messy way by using the Create Table query and select query for printing data. I believe you will think of me how a programmer can be so ridiculous if you see these codes. That's the reason I want to learn if there is a better and standard way to do the same thing or shouldn't do something like that at all? And how other companies do this type of works? You can advise different programming languages if there are any. I read about documents Dynamic Models. I understand a little, but they don't advise to build in that way, so I don't know if … -
Linking two tables with ManyToManyField in Django
I have two db tables: Estados: estado_id, estado_nome Familia: familia_id, familia_nome One family can have multiple Estado, in my mysql db it uses a tertiary table, with composite keys, as we all know django don't supports it. I'm willing to do whatever it takes to make it work. Thank you very much for reading my question and i hope you have a good day. -

How overwrite django-friendship
I am using a third party application called "django-friendship" and I want to adapt it to my project. To adapt it to my project I need to overwrite several functions and urls that come by default, but I don't know how to overwrite them. The source code is here: https://github.com/revsys/django-friendship For example, I want to overwrite the following function in views.py: def all_users(request, template_name="friendship/user_actions.html"): users = user_model.objects.all() return render( request, template_name, {get_friendship_context_object_list_name(): users} ) and for example I want this function to do nothing, just print a text on the screen (not its purpose but to make the example simpler) in this way: def all_users(request, template_name="friendship/user_actions.html"): print("Hello World") I have used the following import: from friendship.views import all_users But it does not work, it still uses the function of the third party application and not mine. On the other hand, "django-friendship" uses the following urls: friendship/ ^users/$ [name='friendship_view_users'] friendship/ ^friends/(?P[\w-]+)/$ [name='friendship_view_friends'] friendship/ ^friend/add/(?P<to_username>[\w-]+)/$ [name='friendship_add_friend'] friendship/ ^friend/accept/(?P<friendship_request_id>\d+)/$ [name='friendship_accept'] friendship/ ^friend/reject/(?P<friendship_request_id>\d+)/$ [name='friendship_reject'] friendship/ ^friend/cancel/(?P<friendship_request_id>\d+)/$ [name='friendship_cancel'] friendship/ ^friend/requests/$ [name='friendship_request_list'] friendship/ ^friend/requests/rejected/$ [name='friendship_requests_rejected'] friendship/ ^friend/request/(?P<friendship_request_id>\d+)/$ [name='friendship_requests_detail'] friendship/ ^followers/(?P[\w-]+)/$ [name='friendship_followers'] friendship/ ^following/(?P[\w-]+)/$ [name='friendship_following'] friendship/ ^follower/add/(?P<followee_username>[\w-]+)/$ [name='follower_add'] friendship/ ^follower/remove/(?P<followee_username>[\w-]+)/$ [name='follower_remove'] friendship/ ^blockers/(?P[\w-]+)/$ [name='friendship_blockers'] friendship/ ^blocking/(?P[\w-]+)/$ [name='friendship_blocking'] friendship/ ^block/add/(?P<blocked_username>[\w-]+)/$ [name='block_add'] friendship/ ^block/remove/(?P<blocked_username>[\w-]+)/$ [name='block_remove'] How can I modify … -
Is including the user field in two related models a bad practice? (Django)
I’m fairly new to Django and programming in general. I’m building a tool for a friend in the construction industry. Basically the client bids for a tender and if they win they sign a contract. A contract can have multiple projects and a project can have multiple jobs. But the user should also be able to create a job for smaller projects that are not under a contract. Every job must be under a project. If the user has a contract I want the user journey to be as the following: Create a contract -> create a project -> create a job. I want to link the contract to the user and the job to the user as well but I’m not sure if it’s a good practice to include the user field twice in two related models. I’d like to know if my solution is wrong and a bad practice, and if there’s a better solution. Thanks! class Contract(TimeStampedModel): owner = models.ForeignKey( get_user_model(), on_delete=models.CASCADE, ) title = models.CharField( max_length=100, blank=False, unique=False) starting_date = models.DateTimeField(default=timezone.now, blank=True) class Meta: verbose_name_plural = "Contracts" def __str__(self): return self.title class Project(TimeStampedModel): name = models.CharField( max_length=50, blank=False, unique=False) contract = models.ForeignKey( Contract, on_delete=models.RESTRICT, blank=False, related_name='contract', … -

How to get an evironment variable value in YAML file?
I am working on a Django project, and I am using GitHub for source control purposes. I am using GitHub actions to run python3 manage.py test when pushing. I don't want to post my secret key to the repository. So I stored it on an environment variable and used os.environ.get('SECRET_KEY') to keep it secret. The problem is that by doing this, GitHub doesn't know what the SECRET_KEY is. There is a way to set custom environment variables in the YAML file in the workflow directory, but if I put the SECRET_KEY there, there is no point in covering it in settings.py. Does anybody know what I can do? -

Suggestions for splitting up a Django model of 1000+ fields
I am looking for suggestions on how to deal with a database table that has 1000 or more columns and I am tying to translate it into one or many Django models. The data also needs to be filtered through API calls within the URL. Every field needs to be able to filter the rest of the data. I have come up with a few solutions and would like input or resources related to them: Just have a model with 1000+ fields - This seems like it would be a nightmare to maintain and would require a lot of brute force coding but would likely work fine if data was selectively returned. Use a JSON field to store all less frequently accessed data - The issue here would be difficulty in filtering the data using Django Filters. Split data into related models connected by One-to-One relationships, as I understand this cuts down on join operations. - This would seem to require more coding than the first option but would be more maintainable. Does anyone have any information or resources on dealing with database tables of this size? -

is there a way to create superuser for django apps on heroku without using CLI?
I changed my db of my app on heroku to not use the sqlite db that is the default for django app, to use the heroku postgres database. however, I want to login to my admin portal on my heroku app, but i am not sure how to create a superuser.
