Elasticsearch not ordering properly
I have this Model class Profile(User): rg = models.CharField(max_length=20, null=True,blank=True) cpf = models.CharField(max_length=15, unique=True, null=True) about = models.TextField(_('about'),max_length = 10000, null=True, blank=True) knowledge = models.ManyToManyField(SubCategory, related_name="profile_knowledge") class Meta: verbose_name = _('profile') verbose_name_plural = _('profiles') db_table = 'pd_profile' permissions = ( ("view_all_users", "Can view user details"), ("edit_all_users", "Can edit user details"), ("search_profile", "Can search talents"), ("user_config", "Can access user config page "), ("add_users_permissions", "Can add global permissions to user"), ("export_user_data", _("Can export users data")), ) def __str__(self): return self.full_name And I Want to do a query through this Profiles like that: query = SearchQuerySet().all().models(Profile) t = query.filter(content=data.get('value')) if not t: suggestion = query.spelling_suggestion(data.get('value')) t = query.filter(content=suggestion) query = t query = query.order_by("full_name") My problem is, the order_by simples doesn't work... My query should return in alphabetical order but it doesn't. Am I doing something wrong? Thanks django-haystack==2.5.0 djangorestframework==3.3.2 elasticsearch==1.5.2 -
Django: manage.py makemigrations --> django.db.utils.OperationalError: no such table
What i did: - deleted the complete db. - deleted the content of the migrations folder then i did: python manage.py makemigrations. I get the above error message.

Pass request to django inherited classes
I am overriding some methods of a popular package, django-activity-stream (I think the package is mostly irrelevant to this question). from app/urls.py I call TeamJSONActivityFeed urlpatterns = [ ... url(_(r'^feeds/organization/(?P<organization_id>.+)$'), TeamJSONActivityFeed.as_view(name='organization_stream')), ... ] TeamJSONactivityFeed then calls 'pass', which I am not too familiar with, and inherits from two other classes, OrganizationStreamMixin and JSONActivityFeed. class TeamJSONActivityFeed(OrganizationStreamMixin, JSONActivityFeed): """ JSON feed of Activity for a custom stream. self.name should be the name of the custom stream as defined in the Manager and arguments may be passed either in the url or when calling as_view(...)

What's next: after successful token created for django all-auth; how to sync google calendars?
Ok, I hope I don't get too beat up here for this question as it is kind of complex. At least in my view, with what I know so far. So the details first: I built a nice app with django that brings in event data for users, utilizes that data for many things (not relevant to this question) but one of the things is that it syncs these events to the users Google calendar. I made the google app within the developer console, and it uses the provided credentials.json file to allow users to authenticate the app, thus creating individual user token.json files per user, then I have another script (not within django, just a custom python file) that runs from a cron job to automatically sync/ update the calendar info from the database to the google calendars. Now, the new problem is having this work without my help. IE: a new user logs in and creates a profile, then if they should choose to sync to their Google calendars I have to be there, running the authentication process from my personal server. So I did that, by moving the whole app to a hosted platform and brought it … -

How to extract a geometry from PostGIS using a view and then add it to a leaflet map in a template using Django
I want to extract polygon geometry data from a PostGIS database using python within a view and add it to my leaflet map within a template. The easiest way seemed to be to extract the data and convert it to GeoJSON using the postgis function ST_AsGeoJSON in my Django view and then render it to the template as context within the L.geoJSON(GEOJSON).addTo(map) function. This does not work. On requesting the map page, the map is now blank and as it seems the GeoJSON is not recognised. I have been able to pass a hard-coded polygon from a view and add it to a map but the geometry data in my postgis database simply isn't valid. Here is a view with a hardcoded polygon that is successfully printed on the map: from django.shortcuts import render def map_view(request, *args, **kwargs): geo_json={ "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {}, "geometry": { "type": "Polygon", "coordinates": [ [ [ -0.10746002197265625, 51.505537109466715 ], [ -0.11466979980468751, 51.498377681772325 ], [ -0.0968170166015625, 51.493568479510415 ], [ -0.09080886840820312, 51.502438390761164 ], [ -0.10746002197265625, 51.505537109466715 ] ] ] } } ] } return render(request ,'map.html', {'geo_json': geo_json}) The map template looks as follows: <!DOCTYPE html> <html> <head> <title>Map Page</title> <link rel="stylesheet" … -

django prefetch_related across mutliple one-to-many relations with filtering conditions
I would like to to a prefetch_related query to get my models and all related models by following one-to-many relations, but with a filtering condition. My goal is to use prefetch_related to obtain all my models and related models in one django query (thus not hitting the database when iterating through related models). I need to go in the one-to-many direction. Say I have the following simple models of Library having many Books having many Pages. from django.db import models class Library(models.Model): name = models.CharField(max_length=50) class Book(models.Model): title = models.CharField(max_length=50) genre = models.CharField(max_length=50) library = models.ForeignKey(Library) class Page(models.Model): content = models.TextField() book = models.ForeignKey(Book) I know I can do models.Library.objects.prefetch_related('book_set__page_set') to get everything one-shot, but what if I want to restrict to book with genre='fantasy'? How can I add this filter condition in my relation-spanning prefetch query? -

Trying to work on a project and get my head around unit Testing. I'm confused why client.get is getting a diffrent redirect than both Firefox and Chrome. Details below, but can someone give me an idea this is occuring. Django Version 3 Python verson 3.8 Running on Ubuntu in WSL in windows. My View Function. class UserDashboardView(View): def get(self, request, *args, **kwargs): return HttpResponseRedirect('/accounts/login') My Test Case import unittest from django.test import TestCase class DashboardPageTest(TestCase): def test_unauthenticated_user_redirected_to_login(self): response = self.client.get('/dashboard') print(response) What occurs. 1 - If I go to /dashboard in Chrome and Firefox the debug shows a 302 with a location key of /accounts/login, and so the browser follows to /accounts/login 2 - If I run the unit test (python manage.py test) the print of the response returns <HttpResponsePermanentRedirect status_code=301, "text/html; charset=utf-8", url="/dashboard/"> I have a feeling their is something I just don't get about the way the browsers vs the TestCase does redirects. Can someone please explain it? -

Best method to do a reminder system
i am not sure if this is considered a vague post but i would love to get some input from our experienced coders here regarding this project that im working on. I wish to build a reminder system for my django app. The app im building is a sales tracker , which tracks where the sales project current is at in the sales pipeline. I broke up this sales pipelines into a series of task that should be completed in a sequence , this activities comes in the form of updating my django model with data . Due to the nature of the business, certain tasks will be left uncompleted until new information is made to the sales person to enter into our system , therefore i wish to create a prompt that generates after a certain threshhold (time) has been crossed . The idea im having in mind is to add in indicator fields which will allow me to query out parts of the projects (models) if they breach the threshhold i set , and return that value as a prompt in my html . However , this seems to over complicate my code base with super complex queries. …
