How to save user preferences without logging user in flutter app
I am working on a flutter app that requires some user data to be saved on server side. But I don't want user to log in using username/password or any social account. Is there a way in flutter to identify the user/device without explicit login ? There seems to be a anonymous login using Firebase but I am looking for a generic solution without any specific backend. I am using Django as my backend. -
Django i18n using a translation from django.contrib module instead of LOCALE_PATHS file
My Django 3.2.9 project displays a translation of both _('Active') and {% translate 'Active' %} that comes from one of Django's modules instead of my application registration. However, other translations from registrations are properly used. By temporarily moving the locale directory outside of the application directory, I confirmed that not only LOCALE_PATHS is correctly set, but also used. Reordering my INSTALLED_APPS also does not change anything. Django seems to insist to use a translation from one of its modules instead from the one in LOCALE_PATHS. The translation in the file looks standard: #: .\registration\templates\users.html:109 #: .\registration\templates\list.html:34 .\registration\views.py:687 msgid "Active" msgstr "XXX" My settings look as follows: BASE_DIR = Path(__file__).resolve().parent.parent LOCALE_PATHS = [ BASE_DIR / 'registration' / 'locale', BASE_DIR / 'administration' / 'locale', ] I confirmed that the path is correct and contains django.po and django.mo in LC_MESSAGES under the language's code directory. As noted above, other translations work correctly. Why does Django use its own version, even though mine is in LOCALE_PATHS and, after changing settings, at the front of INSTALLED_APPS? How can I ensure that Django uses my version? -
Cant login in django when RLS is enabled in the user model?
I have a multi-tenant django application where I've enable Row Level Security using Postgres. Each table has a tenant_id column. I am able to do RLS on the tables using the following postgres policy CREATE POLICY {policy_name} ON "{table_name}" USING (tenant_id::TEXT = current_setting('rls.tenant_id'));" and a middleware from django.utils.deprecation import MiddlewareMixin from django.db import connection class RLSMiddleware(MiddlewareMixin): def process_view(self, request, **kwargs): with connection.cursor() as cur: cur.execute("""select set_config('rls.tenant_id', %(value)s, false)""", dict(value=request.user.pk)) Now when I enable this to the django user model, I'm can't login since the tenant in the current_setting isn't set. But I need to login to set the current_setting. Any work around for this? Can I maybe disable the RLS when in the login page? -

how to retrieve in a sql many to many relationships query all the instances a user is involved with
How can I retrieve all the instances a user is part of in a Many to Many relationship in SQL. (PostgreSQL) I have the following table using django: models.py ... from django.contrib.auth import get_user_model ... User = get_user_model() class Member(models.Model): ... member = models.ManyToManyField(User, related_name="membership") status = models.CharField(max_length=20, choices=STATUS) created = models.DateTimeField(auto_now_add=True) query user = User.objects.get(id=1) user.membership.all() # result => give me all instances where user 1 is associated in Member table What would be the equivalent in sql of the above django query? Any help would be much appreciated -
How to get rid of "%20Profile" in URL Pattern
First, I will search up the user, and then it takes me to a page of a list of users to click onto. After that, when I choose a user I want to click on to check out their profile, it should take me to users page I want to see, but that is where I have a problem. The URL pattern should be, for example /user/MatthewRond/, but instead, I get /user/MatthewRond%20Profile/, which prevents me from seeing Matthew's page because %20Profile was never intended to be in the URL. If I can figure out how to get rid of the %20Profile, my problem should be solved. I read up on what %20 was and what I got from it: it has to do with using and dealing with alphanumeric characters. Regardless none of it helped me figure out how to remove it. As for the code part of it, I am grabbing the default username from the database then grabbing the custom profile I made from that default user. After that, I set the username to the custom profile model I made. I don't believe it is an error with my views, maybe my templates or URLs. views.py def profile_view(request, … -

Why does my Django query from Postgres database return the query set in reverse order

Django annotate() is not adding up the number of entries but is instead repeating them
Background: The Amazon Kindle PaperWhite stores the words we lookup while reading into a sqlite3 database called vocab.db. I am working on a small kindle companion app that takes this db file and imports it into a django table for various processing. I have done this step already. What I would like to do: I would like to query my table KindleLookups for my most difficult words (ex: how many times have I looked up a specific word). I would ultimately like to present this data in a table ordered by highest count. Desired Result: Word Lookup Count Reverberated 3 Troubadour 1 Corrugated 1 My result (undesired): Here Reverberated is being repeated three times each with a lookup count of one, instead of one time with three lookup count. Word Lookup Count Reverberated 1 Reverberated 1 Reverberated 1 Troubadour 1 Corrugated 1 Model: class KindleLookups(TimeStampedModel): book = models.ForeignKey(KindleBookInfo, on_delete=models.CASCADE) word = models.ForeignKey(KindleWords, on_delete=models.CASCADE) ... class KindleWords(TimeStampedModel): word_key = models.CharField(max_length=255, unique=True) word = models.CharField(max_length=255) ... I am trying to accomplish this using annotate(), but this is repeating the rows instead of adding them up for some reason. context['lookup_counts'] = KindleLookups.objects.annotate(word_count=Count("word")) I then thought that I needed to annotate on the actual … -

how to calculate elo efficiently in django?
I'm managing ORM to update ELO rating, but this is hard for me. This is ELO model table. If I insert data between those instances, what will happen? id| league | match_date | player | rating --+--------+------------+---------+-------- 1| 1| 2022-01-01| AAA| 1015.0 (winner) 2| 1| 2022-01-01| BBB| 985.0 (loser) 3| 1| 2022-01-03| CCC| 1016.4 ... 4| 1| 2022-01-03| AAA| 999.4 ... 5| 2| 2022-01-05| AAA| 1015.0 6| 2| 2022-01-05| BBB| 985.0 7| 2| 2022-01-07| CCC| 1015.0 8| 2| 2022-01-07| BBB| 985.0 ... ... data to be inserted => ( league = 1, match_date = 2022-01-02, player = [AAA, CCC] (first is winner) ) Ordering of table is league ASC, match_date ASC. So data will be inserted to between second row and third row. However, rating values what after inserted data isn't currect. What I searching is how to update rating efficiently? Do I run for loop for update all ratings? In my opinion this will be create lots of Hits to DB. I've already created ORM using Subquery, but Subquery doesn't calculate based on calculated data, instead of data from table. It is deprecated because I inserted data. Is there any method using ORM to solve this problem, reply to … -

Not sure what I am doing wrong I will leave below my files. The register method works perfectly but when I am doing the login, everytime the output is user is none. Does anyone know what I did wrong?
