Where is the Postgres username/password being created in this Dockerfile?
So I was following this tutorial: https://realpython.com/blog/python/django-development-with-docker-compose-and-machine/ I have everything up and running, however theres a few things going on that I'm not able to follow or understand. In the main Docker-Compose we have: web: restart: always build: ./web expose: - "8000" links: - postgres:postgres - redis:redis volumes: - /usr/src/app - /usr/src/app/static env_file: .env command: /usr/local/bin/gunicorn docker_django.wsgi:application -w 2 -b :8000 postgres: restart: always image: postgres:latest ports: - "5432:5432" volumes: - pgdata:/var/lib/postgresql/data/ You will notice there is a .env with environment variables which include postgres user and pass. My question is when is the postgres user and password being created? If I run this docker-compose everything works, meaning the web app can pass credentials to the postgress database and establish a connection. I'm not able to follow however, where those credentials are being set in the first place. I was assuming this part (the setup and configuration) of postgres would be contained within the base postgres Dockerfile, and maybe it is but I just don't see where it's setting up a postgres user and password. # vim:set ft=dockerfile: FROM debian:jessie # explicitly set user/group IDs RUN groupadd -r postgres --gid=999 && useradd -r -g postgres --uid=999 postgres # grab gosu … -
Preventing the multi tab login in Django
I have a django application and i want to prevent the user with same credentials to login multiple times. i am able to achieve this using the following code as middleware: class UserRestrict(object): def process_request(self, request): """ Checks if different session exists for user and deletes it. """ if request.user.is_authenticated(): cache = get_cache('default') cache_timeout = 86400 cache_key = "user_pk_%s_restrict" % request.user.pk cache_value = cache.get(cache_key) if cache_value is not None: if request.session.session_key != cache_value: engine = import_module(settings.SESSION_ENGINE) session = engine.SessionStore(session_key=cache_value) session.delete() cache.set(cache_key, request.session.session_key, cache_timeout) else: cache.set(cache_key, request.session.session_key, cache_timeout) However , this prevents the login from different IP addresses. Now i want to implement something that can prevent the login if the user trying to login through different tab of the same browser? PS - i am open if this could be achieved just through javascript as i know that Django user session key is same for the browser. -

single sign on and authorization using python and django/flask
i have a large database which is used for running more than one project with django. I want to implement a system where each projects of these asks for authentication from another project whose only task is to return success/failure flag for user when provided with credentials. Plus, I want to make a system of authorization, like one user from southern region can only see data related to south region,(I think a custom manager will solve my problem). I also want that at UI level i should be able to mark some button or table appear only if user logged in is authenticated and has permissions to view that button and thus access data accordingly. how should i go about the authorization of UI-elements is a great fix for me. Thanks. -
Django Trouble Creating ManyToMany Field
Migrating my Access app to Python/Django. Existing database, so used Inspectdb to create models, which I adjusted as needed until they matched actual db. All models marked Manage = False in Meta. Now I want to add a many-to-many field in a parent table, and having troubles.

Django Url.py Parameters
I followed the Django tutorial on how to use the url dispatcher, but for the life of me cannot figure out why I am getting this error.

How to install Django app on a customers server without exposing the business logic and db access
I'm developing a simple data mining web application using Django Rest Framework + some simple javascript on client side and I want to offer it as a paid service in future. The problem is, that the application will be processing sensitive and some times huge data with restricted access. So my initial idea is to treat this kind of cases by installing the simpler version of the website on the customers server in his intranet (only localhost) and all the data handling could be done on his machine, so there would be no need to set up special permissions to access his data from my website and also I would not have the need to host all the data. The database for the administration of this local server should be of course on my server, so I could easily change the content and functionality through the db. Now the problem is, that I would like to do all this without exposing the business logic of my application. The main data handling functions would be done in cython, so the customer would only see the compiled code. But how to hide my master database for user administration, logging and everything sensitive … -

How to add custom migrations to external Django apps
I've done some monkeypatching to some third-party apps in my custom Django 1.10 app, and now, when I try to create an initial migration, it also generates migrations for these external apps, but it puts those migrations in my virtualenv's site-packages directory, where they can't be version controlled. Moreover, the monkeypatching doesn't actually change the schema. I'm just changing the verbose name and help text to be more user-friendly. There are no changes being made to the database, so there's no actual need to generate migrations for them. How do I generate my app's migration without generating them for external apps? I tried deleting them, and removing them from my app's migration's dependencies list, but then my unittests won't run and I get the error: django.db.migrations.exceptions.InvalidBasesError: Cannot resolve bases for... -
Can I query the DB using a glob pattern?
I'm having trouble trying to query db using a glob pattern. I thougth that maybe glob could be translated to regex, and I know I can query db using regex. I was going to to that translation myself, but I found that python has fnmatch to do just that, explicitly the function translate fnmatch.translate(pattern) Return the shell-style pattern converted to a regular expression for using with re.match().

Django Autocomplete Light - FK Field Results not Forwarding
I'm following along in the DAL documentation to add a filtered field to my form, but the forwarding isn't working to connect one field to the other: Forms.py class PurchaseForm(forms.ModelForm): commodity = forms.ModelChoiceField( queryset=Commodity.objects.all(), widget=autocomplete.ModelSelect2(url='commodity-autocomplete'), required=False, ) class Meta: model = Purchase fields = ["variety"] widgets = { 'variety': autocomplete.ModelSelect2(url='variety-autocomplete', forward=['commodity'], } Views.py class VarietyAutocompleteView(autocomplete.Select2QuerySetView): def get_queryset(self): qs = Variety.objects.all() commodity = self.forwarded.get('commodity', None) print("Commodity:" + str(commodity)) if commodity: qs = qs.filter(commodity=commodity) if self.q: qs = qs.filter(name__istartswith=self.q) return qs I'd like my Variety choices to be filtered by their foreign key relationship to Commodity objects. Both autocomplete fields are working on their own just fine, but the choice from the commodity field is not being forwarded to the VarietyAutocompleteView (my print command prints Commodity:None). Is this perhaps because I am passing a foreign key object? Or have I set this up incorrectly somehow? -
Maximum recursion depth trying to create Django migration
When I try to generate an initial migration for my Django app with: python manage.py makemigrations myapp I get a traceback like: File "/myproject/.env/local/lib/python2.7/site-packages/localflavor/us/models.py", line 21, in deconstruct name, path, args, kwargs = super(USStateField, self).deconstruct() File "/myproject/.env/local/lib/python2.7/site-packages/localflavor/us/models.py", line 21, in deconstruct name, path, args, kwargs = super(USStateField, self).deconstruct() File "/myproject/.env/local/lib/python2.7/site-packages/localflavor/us/models.py", line 21, in deconstruct name, path, args, kwargs = super(USStateField, self).deconstruct() File "/myproject/.env/local/lib/python2.7/site-packages/localflavor/us/models.py", line 21, in deconstruct name, path, args, kwargs = super(USStateField, self).deconstruct() RuntimeError: maximum recursion depth exceeded while calling a Python object The only odd thing I'm doing that's probably the cause is I'm trying to monkeypatch the USStateField from the localflavor package. Specifically, I need to set custom state choices from the field's state list, so I'm doing: from localflavor.us import models as us_models _USStateField = us_models.USStateField class USStateField(_USStateField): description = _("U.S. state (two uppercase letters)") def __init__(self, *args, **kwargs): kwargs['choices'] = MY_STATE_CHOICES kwargs['max_length'] = 2 super(_USStateField, self).__init__(*args, **kwargs) us_models.USStateField = USStateField This worked perfectly in Django 1.7, but now gives me this error in Django 1.10.

How to get a Django ModelForm to redirect to another ModelForm on submit?
I have a template which displays a certain ModelForm at one of the URLs of my Django site. The ModelForm is based on a model with two fields, class ActionCode(models.Model): action_code = models.CharField(blank=False, max_length=10, verbose_name="Action Code") description = models.TextField(blank=True) class Meta: unique_together = ('action_code',) I would like my ModelForm to give the user only the first field (Action Code), then when it is submitted, verify if the value entered already exists or not. If it doesn't already exist, I want to redirect the user to be able to enter a Description for that Action Code (the second field in my model). So I wrote a second ModelForm which uses the Description field of the model, and I would like my first form to redirect to the second form after validating that the data is new. Ideally then, the Description would be linked to this specific piece of data and both would go into the same Django database table (hence them coming from the same model). However, when I enter a new piece of data and hit Submit, the site simply stays at the /action_code/ URL and displays a Submit button, and nothing else. How do I get the first form … -

Heroku free tier billing for a non-stop web and worker process in one application
I have a Python app that pings an API every minute and records data into a database. I also have a Django web app that is the client for displaying this data (it should also not be idling, as I will explain bellow). Heroku recently made changes again to their free tier, allowing 1000hrs/month for verified accounts. I have verified my account to take advantage of this. What is not clear to me is how the usage hours will be counted in my situation. Will my Heroku application accumulate ~750 hours per month, or 2x750 hours after non-stop running? Are the two lines inside the Procfile considered separate dynos, thus each will be accumulating 750 hours per month? Setup Procfile: worker: python api_crawler.py web: gunicorn api_data_client.wsgi --log-file - I found out that if the web process begins to idle after 30 minutes of inactivity, it will also bring down the worker process with it. This is not a desired outcome for me, as I need the worker process to be running non-stop.
