AUTH_USER_MODEL refers to model that has not been installed / Apps aren't loaded yet
So I'm trying to change the User model of a project i started a while back. The app's name is main and i have installed it with "main.apps.MainConfig". I am trying to set USERNAME_FIELD = 'email' My apps.py looks like this: from __future__ import unicode_literals from django.apps import AppConfig from django.contrib.auth.models import User class MainConfig(AppConfig): name = 'main' User.USERNAME_FIELD = 'email' This gives me the error django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. I've tried setting USERNAME_FIELD = 'email' through a user.py file. I set AUTH_USER_MODEL = 'main.user' in settings.py and this is my user.py: from django.contrib.auth.base_user import AbstractBaseUser from django.db import models class User(AbstractBaseUser): email = models.EmailField(_('email address'), unique=True) USERNAME_FIELD = 'email' This yields the following error: django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'main.user' that has not been installed I have no idea whats going on here. Any help is appreciated. Thanks in advance! -

google cloud storage file stuck in time after multiple updates/deletions
I have a cloud storage file frozen in time and will not budge. So far I have: recollected static files (Django) and did an rsync to update deleted the static file in question, recollected static files and did an rsync to update deleted the file in the cloud storage console and re-rsynced deleted the entire bucket and made another bucket with the same name, and rsynced all 85 static files onto it again The first few times I changed the static file, collected them, and rsynced, it worked instantly. Now I have this one line var URL = "http://%/api/recipes/delete/&/".replace("%", API_BASE).replace("&", recipe_id); stuck in time, frozen in this bucket. In Django, my file correctly reads var URL = "/api/recipes/delete/&/".replace("&", recipe_id); The change is checked into git. This bucket has not updated at all, and the file was still being served even after I deleted the file. The file was still being served after I deleted the entire bucket, which seems like a bug I'm out of ideas if even deleting and remaking the entire bucket doesn't change anything. Any help appreciated, thank you -
Saving BytesIO to Django ImageField
I have a web scraper that I want to download an image of the page it's scraping and save it as a "screenshot" ImageField in a Django model. I am using this code: def save_screenshot(source,screenshot): box = (0, 0, 1200, 600) im = Image.open(io.BytesIO(screenshot)) region = im.crop(box) tempfile_io = io.BytesIO() region.save(tempfile_io, 'JPEG', optimize=True, quality=70) source.screenshot.save(source.slug_name+"-screenshot",ContentFile(tempfile_io.getvalue()),save=True) It saves the screenshot to the /media/news_source_screenshots/ directory but doesn't save it to the model. The model field is defined as: screenshot = models.ImageField(upload_to='news_source_screenshots',blank=True,null=True) What am I missing? -

Django Meta ordering in related query
How do you set a default order for Django queries that works on related managers? You can set a default order with Meta.ordering: class Subject(Model): title = TextField() class Course(Model): subject = ForeignKey(Subject) class Meta: ordering = ['id'] This will set the order when you run Course.objects.all(). But when you run subject.course_set.all(), the courses can be out of order. -

Which Python module to use for interpreting HTML form values without editing form page?
I have an HTML form that consists of a ton of different values and form fields, and I want to submit those values to a Python file, and have the Python file return (to the user) whether the value was "correct" or "incorrect". I'm a fairly new programmer, and my only Python web development experience is with Django. I know for Django you have to add a lot to the form to make it usable with Django. Is there a similar framework (not sure if that includes thing like the CGI module) that doesn't require the form to be modified to properly interpret/return script values? Potentially important info: All data is from radio buttons There are an average of 20 sets of 5 radio buttons per form, and 40 total forms. One radio button (per set) has a "correct" value, the other four have an "incorrect" value A user can select one of the five radio buttons per set I do not need to record the values, just give the user a response based on their submission once they have submitted it. Thanks for any help. -

Django web frame real time data
i am writing a Django project that display data from mysql database, database is constantly getting update, how can i constantly send data in view.py. i tried looking at many modules i came across celery,Tornado, Django channels but they are mostly written for chat applications, also i tried considering using Node.js with Django. but what is the real solution for a simple data update in Django ? Right now I simply use this code in my html file that refresh the page and gets the last data but the problem is that it makes the website run very slow : <script> var myVar = setInterval(ReLoad , 2000); //refresh every 2 seconds function ReLoad() { $("#live").load(document.URL + " #live"); } </script> -

Django - How to use my custom filters inside any included template?
I can't make use of my filters on my included child view, the filter works when is written directly, but I need the child view as inclusion... Here is the filter: from django import template from django.template.defaultfilters import stringfilter register = template.Library() @register.filter def lower(value): return value.lower() Here is how I call my template: {% load app_filters %} {% include 'view.template.html' %} view.template.html <h1>{{ 'Hello World!' | lower }}</h1> But the thing is that it doesn't work been included, unless I had to add the {% load app_filters %} inside view.template.html but I need this template for my angular app too, so I can't write this line in the template. How could I inject my custom filters to the included view without modifying the view? It is possible to pass as {% include 'view.template.html' with app_filters=app_filters %}? It is only the idea. -
Django command throws TypeError: handle() got an unexpected keyword argument

Signing in through AJAX post request on Django All-auth
According to the documentation of django all-auth , it supports logging in through AJAX requests.When I make a normal post request to "accounts/login/" ,content type of the response header is "text/html".

Passing URL Django Pattern in Datatables Column
I'm trying to pass a url into the "Guest Name", where the user clicks on the user and a modal will pop up that displays a form that you can input/view information related to that particular guest. I've tried fooling around with the render function, but haven't had much success. If I were to be doing this purely in Django, I would want the equivalent of {% 'namespace:guest_data_form' guest.pk %}, which would call a view to render the form within a modal. How would I accomplish the same within datatables? <script type="text/javascript" language="javascript" class="init"> $(document).ready(function() { $('#example').DataTable( { autoWidth: true, ajax: { url: "{% url 'guest_data_api' guest.id %}" }, columns: [ { "data" : "Room Number" }, { "data" : "Occupancy" }, { "data" : "Guest Name" }, { "data" : "Check In" }, { "data" : "Check Out" } ], "columnDefs": [ { "width": "15%", "targets": 2 } ] } ); } ); </script> -

Risks of using Docker in production
Consider I successfully created a Docker machine on DigitalOcean running some containers. Suppose that the local computer with which I configured the machine is gone (exploded, burnt, vaporized). How can I recover all the configuration files to reconnect to the machine? Docker is great, but it seems to lack of some really basic stuff: https://github.com/docker/machine/issues/1328 I am quite concerned of using it for production if all the management tools are bound to one local physical device. Maybe I am missing something, that is too strange to be true, but all the documentation I have found does not cover anything about this argument. -
