Unable to expose docker container port to another container
I have been trying for days to solve the following issue. I cannot make container A expose port for container B in docker compose. The two containers, however, can ping the other (so they are on the same network e.g. ping db from Container B resolves the IP). Example: Container A: postgres (exposes port 5432) Container B: django project (trys to connect to postgres on port 5432) django.env DB_NAME=freelancetracker DB_USER=freelance DB_PASSWORD=freelance1234 DB_HOST=postgresdb DB_PORT=5432 postgres.env POSTGRES_PASSWORD=freelance1234 POSTGRES_USER=freelance POSTGRES_DB=freelancedb version: "3.9" services: db: image: postgres env_file: - postgres.env ports: - 9001:5432 environment: - "POSTGRES_HOST_AUTH_METHOD=trust" volumes: - ./data/db:/var/lib/postgresql/data web: build: context: . network: host args: progress: plain volumes: - .:/code ports: - 9101:9100 env_file: - django.env depends_on: - db Container postgres: { "Id": "sha256:680aba37fd0f0766e7568a00daf18cfd4916c2689def0f17962a3e1508c22856", "RepoTags": [ "postgres:latest" ], "RepoDigests": [ "postgres@sha256:901df890146ec46a5cab7a33f4ac84e81bac2fe92b2c9a14fd649502c4adf954" ], "Parent": "", "Comment": "", "Created": "2023-02-11T05:02:41.267291947Z", "Container": "7f186dd9993cc4c4ee68d8e17c42f9205a5b09b06131c62d79861b85ff4aec1d", "ContainerConfig": { "Hostname": "7f186dd9993c", "Domainname": "", "User": "", "AttachStdin": false, "AttachStdout": false, "AttachStderr": false, "ExposedPorts": { "5432/tcp": {} }, "Tty": false, "OpenStdin": false, "StdinOnce": false, "Env": [ "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/lib/postgresql/15/bin", "GOSU_VERSION=1.16", "LANG=en_US.utf8", "PG_MAJOR=15", "PG_VERSION=15.2-1.pgdg110+1", "PGDATA=/var/lib/postgresql/data" ], "Cmd": [ "/bin/sh", "-c", "#(nop) ", "CMD [\"postgres\"]" ], "Image": "sha256:073c3dc2528e2f091ce4497b9f51f4a69105de3faff43bd8675b99c5c2e470a6", "Volumes": { "/var/lib/postgresql/data": {} }, "WorkingDir": "", "Entrypoint": [ "docker-entrypoint.sh" ], "OnBuild": null, "Labels": {}, "StopSignal": "SIGINT" }, … -

How to Store file_paths for fast matching queries?
I am trying to store the file path of all files in a BUCKET. In my case a bucket can have millions of files. I have to display that folder structure in a UI for navigation. storage_folder: - bucket_1 - bucket_files.txt - bucket_metadata.txt - bucket_2 - bucket_files.txt - bucket_metadata.txt # bucket_file.txt contains folder1/sub_folder1/file1.txt folder1/sub_folder1/file2.zip folder1/sub_folder2/file1.txt folder2/..... .... .... Current approach: I will create a .txt file corresponding to each BUCKET which will contain absolute paths of each file in that bucket. Then whenever a query comes the whole file goes through lots of string matching which is really slow. What I want: I want to store those files in a tree based structure for optimized queries. Is there any solution for this? for context I am building my backend in Django. -

Django+PostgreSQL: creating user with UserCreationForm saves it to auth_user table, but not to the table created for the User model
I'm learning Django and now developing a simple food blog app for practice, using Django 4.1 and PostgreSQL. Since I'm not quite good yet at understanding how some concepts work in practice, I started with creating the basic structure (models, views, etc.) as per MDN Django Tutorial, and then went on adding other things based on various Youtube tutorials. I also created some users with Django Admin to see if everything works, and work it did... until I implemented user registration. I successfully registered several users via registration form and could log in as anyone of them, view their profile page, etc., but found out they were not displayed anywhere in the users list. At the same time, I couldn't log in to any of the accounts I created previously with Django Admin. Having searched for errors through the code of my 'recipeblog' app, I finally went to check the database I used. There, I found two different tables with different users: the first one named recipeblog_user, containing users created with Django Admin, and the second one named auth_user, containing users created with registration form. Thus I seem to have found the problem, but it got me stuck, for I … -

I was wondering if it would be possible to run my Django rest API along side my react app on a custom domain HTTPS server. Currently I have my website on a google cloud VM with a custom domain attached to it via the CloudFlare service. The issue that I am currently facing is that I cannot set the csrftoken cookie on my browser since I would be trying to access my API on port 8000 (Unsafe) while my page is on HTTP or even HTTPS on a different domain. What should I do in this situation? What would be my best option? I have tried setting the CSRF_COOKIE_SAMESITE to None but it requires me to set Secure as well but once I do this I end up with a similar problem where I cannot access the token as my API is not on a secure server. -

How to get the detailed page by slug and not id in Django Rest Framework class based views
I am building an API using Django Rest Framework. I have the /api/localities endpoint where all of the objects on my database are displayed. Now I want to create the endpoint for a single page of a particular locality, and I want to make it by slug and not id for example /api/localities/munich. I am using Class based views and right now I can get the single page by id, for example /api/localities/2, but I want to change that to the slug. How can I do this? Here is my code: models.py class Localities(models.Model): id_from_api = models.IntegerField() city = models.CharField(max_length=255, null=True, blank=True) slug = models.CharField(max_length=255, null=True, blank=True) postal_code = models.CharField(max_length=20, null=True, blank=True) country_code = models.CharField(max_length=10, null=True, blank=True) lat = models.CharField(max_length=255, null=True, blank=True) lng = models.CharField(max_length=255, null=True, blank=True) google_places_id = models.CharField(max_length=255, null=True, blank=True) search_description = models.CharField(max_length=500, null=True, blank=True) seo_title = models.CharField(max_length=255, null=True, blank=True) def __str__(self): return self.city serializers.py from rest_framework import serializers from .models import Localities class LocalitiesSerializers(serializers.ModelSerializer): class Meta: model = Localities fields = ( "id", "id_from_api", "city", "slug", "postal_code", "country_code", "lat", "lng", "google_places_id", "search_description", "seo_title", ) views.py from django.shortcuts import render from django.http import HttpResponse from wagtail.core.models import Page from .models import LocalityPage, Localities from django.core.exceptions import ObjectDoesNotExist from … -

How to align text or url in Django template? - Python Crash Course, Project "Learning Log"
I am creating "Learning Log" Django web-application using "Python Crash Course, 2nd edition" book. But since I reached 20th chapter of the book, I started having problems. I created a template, that displays all entries of the particular topic. On the page we have entry title, date, a button to edit it, and of course its text. Following the book, I use bootstrap4 to make pages looks more beautiful. But I would like to align the entry date and the "edit entry" url to the right side. I tried style="text-align:right;" , but it doesn't work. I am really new to web development , so I beg you to not judge me strictly :) Page with topic and its entries topic.html {% extends 'learning_logs/base.html' %} {% block page_header %} <h3>{{ topic }}</h3> {% endblock page_header %} {% block content %} <p> <a href="{% url 'learning_logs:new_entry' topic.id %}">Add a new entry</a> </p> {% for entry in entries %} <div class="card mb-3"> <h4 class="card-header"> {{ entry.title }} <small style="text-align:right;"> {{ entry.date_added|date:'M d, Y'}} <a style="text-align:right;" href="{% url 'learning_logs:edit_entry' entry.id %}">edit entry</a> </small> </h4> <div class ="card-body"> {% if entry.text|length > 500 %} {{ entry.text|linebreaks|truncatechars:500 }} <p><a href="{% url 'learning_logs:entry' entry.id %}">Read more</a></p> {% …
