Django - Is this solution DRY or is there a better way to model these profile classes and subclasses?
Basically, I have the following requirements: A user has a personal user profile An organisation can have a staff profile The staff profile can be independent or link to a user The organisation can edit the staff profile without changing the users' personal user profile A user changing their personal user profile wouldn't affect an organisations staff profile of the user A user can be staff at multiple organisations (and hence have multiple staff profiles) A user doesn't have to be staff Currently I have the following classes (Irrelevant fields removed for simplicity) profiles.models.py class Profile(TimeStampMixin): title = models.CharField(max_length=6, choices=Title.choices, blank=True) forename = models.CharField(max_length=50, blank=True) surname = models.CharField(max_length=50, blank=True) class UserProfile(Profile): user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name="profile", on_delete=models.CASCADE) class StaffProfile(Profile): user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True, db_index=True, related_name="staff_profiles") organisations.models.py class Organisation(TimeStampMixin): staff = models.ManyToManyField('profiles.StaffProfile', blank=True, related_name="organisations") What I'm wondering is whether this solution is DRY and whether it's the best way of dealing with the requirements? The reason I'm not sure is because I've contemplated having StaffProfile extend UserProfile instead of Profile and changing the OneToOneField in UserProfile to a ForeignKey Field however this seems like it would complicate finding a User's personal profile from their staff profile. Unless I change the related_name … -
Postgres procedure not updating selected row
I'm working on a Django application that uses Stored Procedures on a PostgreSQL database. I'm stuck in a very strange (for me, at least) problem. I have the following SP code: create procedure inbound_550(p_operation_id integer) language plpgsql as $$ declare file_operation record; ... begin select oo.id, oo.file_id, ot.transaction_type_id, ot.code into file_operation from operations_operation oo join operations_type ot on ot.id = oo.type_id where oo.id = p_operation_id; for line in # select some records from other tables using parameter p_operation_id on some FKs loop # business logic here with some calculations and some inserts sum_tax_day = X # some value end loop; operation_avg_year_tax = ((1 + (sum_tax_day / 100)) ^ 252) - 1; update operations_operation set avg_year_tax = operation_avg_year_tax where id = p_operation_id; end $$; The problem is, when I call this procedure from the console it runs fine and the field avg_year_tax gets updated with the operation_avg_year_tax value but, when I call the procedure from my application using Python and psycopg2 the field is not updated, it seems that the update statement is ignored. Here is the Python code used to call the procedure: from django.db import connection class Inbound: def __init__(self, operation): self.operation = operation def main(self): conn = connection … -

Here's the code of the translator function: def translator(phrase): translation = "" for letter in phrase: if letter.lower() in "a": if letter.isupper: translation = translation + "U" else: translation = translation + "u" elif letter.lower() in "t": if letter.isupper: translation = translation + "A" else: translation = translation + "a" elif letter.lower() in "c": if letter.isupper: translation = translation + "G" else: translation = translation + "g" elif letter.lower() in "g": if letter.isupper: translation = translation + "C" else: translation = translation + "c" return translation However, I am stuck in showing this funcion in my web, here's the code in views.py: from .translate import translator def translated_view(request): text = request.GET.get('text') print('text:', text) translate = translator dt = translator.detect(text) tr = translated.text context = { 'translated': tr } return render(request, context, 'main/translated.html') Here's the template that should would show the translation. {% extends "base.html"%} {% block content%} <div > <center><h2 class = "display-4">DNA TRANSLATED SUCCESFULLY INTO</h2></center> <br> <br> <br> <h3> {{ translated }} </h3> </div> {% endblock content%} -
I can not access to mount directory from Django when using docker
I run Django in docker and I want to read a file from host. I mount a path in host to container using following command in my docker-compose file: volumes: - /path/on/host/sharedV:/var/www/project/src/sharedV Then I execute mongodump and export a collection into sharedV on host. After that, I inspect web container and go to the sharedV directory in container and I can see the backup file. However, when I run os.listdir(path) in django, the result is empty list. In the other word, I can access to sharedV directory in Django but I can not see its contents! Is there any idea that how can I access to host from a running container? thanks -

Django makemigrations Segmentation fault
I am trying to run a Django rest api in Docker-compose on a raspberry pi 3B with 1gb of RAM. The postgresql database and the nodejs frontend run without any problem. But for the django backend the output of docker-compose up is a segmentation fault: backend | + python3 manage.py makemigrations restapi backend | No changes detected in app 'restapi' backend | scripts/start_server.sh: line 29: 13 Segmentation fault (core dumped) python3 manage.py makemigrations restapi line 29 in start_server.sh refers to: python3 manage.py makemigrations restapi Any ideas where the segfault is coming from or how I could find out what's the problem? Might this be a memory issue? I configured a 8GB swap alongside the 1GB RAM. Would this prevent python to run out of memory? The exact same configuration runs fine on my PC with 8GB RAM so I suppose there isn't a problem with my django models. Edit: if i skip the makemigrations and jump to migrate I also get a segfault: backend | Applying restapi.0001_initial... OK backend | Applying sessions.0001_initial...

Django-haystack & solr : Increase the number of results

Django Tweepy API.friends clarification
I have an app that fetches friends and followers from a logged user then serves them on an html table. I had the the following code checking for entries that were neither on update and deleted them. # Setup Twitter API instance of logged User api = get_api(user) me = api.me() # Fetch logged User's friends user_friends = api.friends(me.screen_name, count=200) # Fetch logged User's followers user_followers = api.followers(me.screen_name, count=200) # Check for excess entries and delete them if any existing_contacts = Contact.objects.filter(user=user) for contact in existing_contacts: if contact not in user_friends and contact not in user_followers: contact.delete() I decided to use cursor method in order to provide scalability but after changes current code is deleting all contacts. Probably cause it doesn't find the object in any of the lists. Any ideas? # Setup Twitter API instance of logged User api = get_api(user) me = api.me() # Fetch logged User's friends user_friends = tweepy.Cursor(api.friends, me.screen_name, count=200).items() # Fetch logged User's followers user_followers = tweepy.Cursor(api.followers, me.screen_name, count=200).items() # Check for excess entries and delete them if any existing_contacts = Contact.objects.filter(user=user) for contact in existing_contacts: if contact not in user_friends and contact not in user_followers: contact.delete() models.py class Contact(models.Model): twitter_id = models.CharField(max_length=30) profile_image_url … -

Django related_name not working while using self reference in many-to-many field
I'm currently trying to create following relationship between users, so I used a many-to-many field in the User model to reference itself. class User(AbstractUser): followers = models.ManyToManyField('self', related_name='following') def __str__(self): return self.username However, when I tested this model using shell and trying to access the related_name, it reported error has occurred. >>> u1 = User.objects.get(pk=1) >>> u1.following.all() Traceback (most recent call last): File "<console>", line 1, in <module> AttributeError: 'User' object has no attribute 'following' Now I'm really confused, and really need help or alternative ways of doing this.
