Best practices for sharing database across multiple sites (specifically code versioning with schema changes)
We would like to run multiple django sites with the same codebase, but different versions due to different deploy dates, and would like to share a common content database. We are unsure how to deal with schema changes if all django server instances cannot be guaranteed to be updated at the same time. This is the beginning of the project, we current have one site and are looking to extend this to two sites, thereby introducing the problem. We foresee an issue if we make a schema change by updating the django code and running migrations on one site, but cannot deploy to the site for some time (due to deployment restrictions) that the other site would suffer because there would be a schema mismatch between the django expectation of the database structure and the actual database structure. Since we want to share a content database across multiple sites, we are looking for ways to solve this issue. We have considered having a local copy of the master content database for each site, which the master would replicate to in near real time. If there was a version mismatch then the older site would have the replication disabled. However then … -
Wagtail: Prefered way to disable the admin dirty forms check
Ive written my own custom panels that link to adminmodels to be able to add some extended functionality to my pageobjects. But I am having trouble with the dirtycheck added by wagtails admin (onbeforeunload hook that opens an alert), that keeps on nagging the users about not leaving the page, even though I havent changed anything in the input forms. Is there a reliable way to disable the dirtycheck for certain pagetypes? -

Django prefetch_related and performance optimisation with multiple QuerySets within loops
Effectively I have multiple Queries within loops that I am just not happy with. I was wondering if someone had the expertise with prefetch_related and other Django Query construction optimisation to be able to help me on this issue. I start with: users = User.objects.filter(organisation=organisation).filter(is_active=True) Then, I start my loop over all days starting from a certain date "start_date": for date in (start_date + datetime.timedelta(n) for n in range((datetime.datetime.now().replace(tzinfo=pytz.UTC) - start_date).days + 1)): I then within this loop over a filtered subset of the above users for date in (start_date + datetime.timedelta(n) for n in range((datetime.datetime.now().replace(tzinfo=pytz.UTC) - start_date).days + 1)): for user in users.filter(created_date__lte=date).iterator(): Ok, so firstly, is there any way to optimise this? What may make some of the hardcore Django-ers loose their tether, I do all of the above inside another loop!! for survey in Survey.objects.all().iterator(): for date in (start_date + datetime.timedelta(n) for n in range((datetime.datetime.now().replace(tzinfo=pytz.UTC) - start_date).days + 1)): for user in users.filter(created_date__lte=date).iterator(): Inside the last loop, I perform one final Query filter: survey_result = SurveyResult.objects.filter(survey=survey, user=user, created_date__lte=date).order_by('-updated_date')[0] I do this because I feel I need to have the user, survey and date variables ready to filter... I have started thinking about prefetch_related and the Prefetch object. … -

Success redirect to profile form gives TypeError at /profile/ join() - argument must be str or bytes, not 'NoneType'
I have an extended User model called UserProfile, and the update view uses the SuccessMessageMixin to redirect on successful update. The problem is that something in the django code is trying to join an unset var (paths) to the path, and I'm not sure why. user_profile/views.py class UserProfileView(LoginRequiredMixin, SuccessMessageMixin, UpdateView): model = UserProfile form_class = UserProfileChangeForm success_url = reverse_lazy("user_profile:profile") # success_url = "/success/" success_message = "Profile updated" def get_object(self, *args, **kwargs): return self.request.user def post(self, request, *args, **kwargs): form = self.form_class(request.POST, instance=request.user) if form.is_valid(): profile = form.save(commit=False) profile.save() return render(request, self.template_name, {"form": form}) Stack trace on submit of form with changed data (the data does actually get updated, so this is purely a redisplay issue).

How to encode an uploaded image using base64 and create a brand new PNG image by decoding it?
Currently, I created a Django html page that'll allow a user to upload an image. Images are restricted to only JPG, JPEG, PNG and SVG. If uploaded correctly, the image is stored as in a png extension. After this, I want to grab the path and encode it using base64. Using this string, I want to then create a brand new image which should hold a PNG extension and then store it in the database. How should I do this? Or better yet, is there a better way to do it? I feel that converting an existing png image to a new png image again might be tedious. Please do help. Code below: validators.py def validate_file_extension(value): import os from django.core.exceptions import ValidationError ext = os.path.splitext(value.name)[1] # [0] returns path+filename valid_extensions = ['.jpg', '.png', '.jpeg', '.svg'] if not ext.lower() in valid_extensions: raise ValidationError(u'Unsupported file extension.') models.py from django.db import models import os from PIL import Image from datetime import date import datetime from .validators import validate_file_extension import base64 def get_directory_path(instance, filename): today = date.today() t = datetime.datetime.now() day, month, year = today.day, today.month, today.year hour, minutes, seconds = t.hour, t.minute, t.second filename = str(day) + str(month) + str(year) + str(hour) + … -
Django middleware skipping data attribute in static url
i have a simple middleware builded in django app. It works for push notification image tracking. Logic: if push shows up, middleware should see it by data attribute and update status of my Push object. My middleware code: class PushStatistic: def process_request(self, request): if request.GET.get('pushid'): print('entered push id for readed') pushid = request.GET.get('pushid') print(f'Push id - {pushid}. Updating...') if pushid: pushid = int(pushid) if Push.objects.filter(id=pushid).exists(): Push.objects.filter(id=pushid).update(status=4) print('status updated') so when i send notification, icon url for push looks like this: https://test.com/static/img/pic.png?pushid=9403687 When push showing up, i see the picture, but middleware not working. I use the same middleware logic for push-clicks tracking, and it works well. I cant understand what im doing wrong now, cause as i see it, its just the same GET request. Maybe its because its static url? Also i build django-view with same logic for push tracking AND IN VIEW IT WORKS: def fileresp(request, filename): if request.GET.get('pushid'): pushid = request.GET.get('pushid') Push.objects.filter(id=pushid).update(status=4) image_data = open(f"{project_settings.BASE_DIR}/media/{filename}", "rb").read() return HttpResponse(image_data, content_type="image/png") But i want to build it in django-middleware for more universality. Is it possible? -

Django doesnt' read second templatetags folder
Say I have a project and two registered apps. Inside my apps I created templatetags package with custom tags that I want to use in corresponding html templates: Project --App1 | |----templatetags | |----custom_tags.py |----__init__.py --App2 | |----templatetags | |----custom_tags.py |----__init__.py And it looks like django sees only one templatetags folder. I use {% load custom_tags %} in html templates in both apps. When there is only one templatetags folder then corresponding custom tags work (so there is no error in custom_tags.py). I tried to rename one file to eg 'custom_tags_app1' and then {% load custom_tags_app1 %} in html templates in app1, but then it throws error saying: 'custom_tags_app1' is not a registered tag library. Must be one of: . . custom_tags ... When I renamed it I tried to import 'custom_tags_app1' in the shell and it worked What am I missing here? What should I do to make it work, when they both work independently, but don't work together? -
Cannot open ContentFile containing BytesIO content again once it is closed
Once a ContentFile object containing binary data is closed, it isn't possible to open it again: >>> content = ContentFile(b'\x00\x01\x00\x02\x00\x00\x00\x03') >>> content.closed False >>> content.file <_io.BytesIO object at 0x7fa0cd33c8e0> >>> content.file.closed False >>> content.file.close() >>> content.file.closed True >>> content.closed True >>> content.open() *** ValueError: I/O operation on closed file. >>> content.read() *** ValueError: I/O operation on closed file. >>> content.file.read() *** ValueError: I/O operation on closed file. This process naturally occurs when a serializer writes a content file to a field, making it impossible to open the file from memory later on during another process without downloading it first.

Python testing: mocking a function that's imported AND used inside another funciton
Due to circular-import issues which are common with Celery tasks in Django, I'm often importing Celery tasks inside of my methods, like so: # some code omitted for brevity # accounts/models.py def refresh_library(self, queue_type="regular"): from core.tasks import refresh_user_library refresh_user_library.apply_async( kwargs={"user_id": self.user.id}, queue=queue_type ) return 0 In my pytest test for refresh_library, I'd only like to test that refresh_user_library (the Celery task) is called with the correct args and kwargs. But this isn't working: # tests/test_accounts_models.py @mock.patch("accounts.models.UserProfile.refresh_library.refresh_user_library") def test_refresh_library(): Error is about refresh_library not having an attribute refresh_user_library. I suspect this is due to the fact that the task(refresh_user_library) is imported inside the function itself, but I'm not too experienced with mocking so this might be completely wrong. -

Converting attributes of class to a django models subclass
I have a bunch of classes that I'm now trying to incorporate into django. For example, I have a Base class that all my other classes derive from: class Base: def __init__(self, label: str = 'Base'): self.label = label An example of a sublcass would be a Person class: from typing import Any, Dict class Person(Base): def __init__(self, name: str, attributes_to_options: Dict[str, Any], **kwargs): super().__init__(**kwargs) self.name = name self.attributes_to_options = attributes_to_options I would use this as: alex = Person(name='Alex', attributes_to_options={'age': 10, 'is_happy': True}, label='Person:Alex') My question is, how do I incorporate such a class into django? Is it as simple as inheritting from models.Model? e.g. from django.db import models class Person(Base, models.Model): def __init__(self, name: str, attributes_to_options: Dict[str, Any], **kwargs): super().__init__(**kwargs) self.name = name self.attributes_to_options = attributes_to_options But then how do I specify the models.CharField for the two attributes name and attributes_to_options?

Django sessions: How to include session ID in every log record?
I would like to include session ID (at least portion of it) in every log entry in Django. This would help me group together logs for each user session in case several users are interacting with my Django API at the same time. I know I can retrieve session ID from Request object (when it exists) but I would have to do so for every logger.info() across the whole framework. Instead it would be much better to have Request somehow available in settings.py so that I can prepend the ID to my formatter's format string inside LOGGING config. This would ensure that the session ID is included in every log entry and I would not need to think about it in every view or serializer, etc. But I haven't found a way how to make Request or Session available in settings.py. -
Django - update dictionary with missing date values, set to 0
So to display a small bargraph using Django and Chart.js I constructed the following query on my model. views.py class BookingsView(TemplateView): template_name = 'orders/bookings.html' def get_context_data(self, **kwargs): today = datetime.date.today() seven_days = today + datetime.timedelta(days=7) bookings = dict(Booking.objects.filter(start_date__range = [today, seven_days]) \ .order_by('start_date') \ .values_list('start_date') \ .annotate(Count('id'))) # Trying to add 0 for the missing start_date within the range for start_date in (seven_days): if start_date not in bookings: bookings.update({start_date : 0}) context['booking_list'] = bookings This led me to the following result; { datetime.date(2019, 8, 6): 12, datetime.date(2019, 8, 7): 12, datetime.date(2019, 8, 9): 4, datetime.date(2019, 8, 10): 7, datetime.date(2019, 8, 12): 7 } To use the data in a chart I would like to add the missing start_dates into the dictionary but I'm not entirely sure how to do this. So I want to update the dictionary with a value "0" for the 8th and 11th of August. I tried to add the for statement but I got the error; "'datetime.date' object is not iterable"
