MySQL + Django / ERROR 1045 and CommandError
I configured MySQL as follows: CREATE DATABASE IF NOT EXISTS foodb; CREATE USER IF NOT EXISTS 'foo'@'localhost'; ALTER USER 'foo'@'localhost' IDENTIFIED BY 'qux'; GRANT ALL ON foodb.* to 'foo'@'localhost'; SHOW GRANTS FOR 'foo'@'localhost'; FLUSH PRIVILEGES; SELECT user, host, authentication_string FROM mysql.user ORDER BY user, host; When I run python manage.py dbshell I get the following error: ERROR 1045 (28000): Access denied for user 'foo'@'localhost' (using password: YES) CommandError: "mysql --user=foo --host=localhost foodb" returned non-zero exit status 1. Also, this query SHOW GRANTS for 'foo'@'localhost'; returns +--------------------------------------------------------------+ | Grants for foo@localhost | +--------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'foo'@'localhost' | | GRANT ALL PRIVILEGES ON `foodb`.* TO 'foo'@'localhost' | +--------------------------------------------------------------+ 2 rows in set (0.00 sec) Finally, switching user to root and the root account password works just fine. So I think the issue must be with the user permissions on MySQL itself. What additional permissions does 'foo'@'localhost' need for this to work? -
Is it possible to use `__date` for a `timestamp` field in `filterset_fields` list of `DjangoFilterBackend`
I am using ListAPIView to list the records from my database table which is represented as ExpiredOrders(models.Model) in models.py. The Django model has several columns along with created_at and modified_at as timestamp. I want to filter the records on the created_at against the query parameters created_at. I am trying to use the DjangoFilterBackend to achieve the same. filter_backends = [DjangoFilterBackend] filterset_fields = ['craeted_at__date'] However, it return me an error - 'Meta.fields' must not contain non-model field names: created_at__date As created_date is a timestamp and in query parameter I will only get the date as YYYY-MM-DD, I am using __date to make the record of database table comparable with the query parameter. The other way to achieve this is - def get_queryset(self): try: queryset = ExpiredOrders.objects.filter(created_at__date=self.query_params['created_at']) except: queryset = ExpiredOrders.objects.all() return queryset I want to know if it is possible to get it done by just defining the filed name in the list filterset_fields. Also, please explain me what does this __ means here. Best to my knowledge it is a convention to represent class variable or methods which must not be used with the objects of other class or subclasses. Perhaps, this concept is known as name mangling in Python. … -
`HyperlinkedIdentityField` requires the request in the serializer context. Add `context={'request': request}` when instantiating the serializer
This is what my serializers.py file is looking like: from rest_framework import serializers from .models import * class EinsatzSerializer(serializers.ModelSerializer): class Meta: model = Einsatz fields = ('pk', 'url', ...) # ... = all my other fields But when I create an "Einsatz", I get this error: Exception Value: `HyperlinkedIdentityField` requires the request in the serializer context. Add `context={'request': request}` when instantiating the serializer. Exception Location: .../venv/lib/python3.9/site-packages/rest_framework/relations.py, line 378, in to_representation I don't understand why I am getting this Error, when I am not even using HyperlinkedIdentityField. And where would I even put context={'request': request}? I also have a views.py and urls.py to show if needed. Thank you in advance! -
How to remove nesting from Django REST Framework serializer?
I have two models defined in my models.py file: class Album(models.Model): album = models.CharField(max_length=100) band = models.CharField(max_length=100) class Song(models.Model): album = models.ForeignKey(Album, on_delete=models.CASCADE) song = models.CharField(max_length=100) For these, I have defined the serializers in my serializers.py file as: class AlbumSerializer(serializers.ModelSerializer): class Meta: model = Album fields = "__all__" class SongSerializer(serializers.ModelSerializer): album = AlbumSerializer() class Meta: model = Song fields = "__all__" When I make a request, the data I get is in this format: [ { "id": 1, "album": { "id": 1, "album": "Hybrid Theory", "band": "Linkin Park" }, "song": "Numb" }, { "id": 2, "album": { "id": 1, "album": "Hybrid Theory", "band": "Linkin Park" }, "song": "In the End" } ] How do I remove the nesting from the album name, from the songs Serializer? I would want data something like this: [ { "id": 1, "album_id": 1, "album": "Hybrid Theory", "band": "Linkin Park" "song": "Numb" }, { "id": 2, "album_id": 1, "album": "Hybrid Theory", "band": "Linkin Park" "song": "In the End" } ] -

Django QuerySet annotation with Case appears to be falsely positive
I am trying to annotate a QuerySet on a case-by-case basis but I get all results positive (1) when they should be all but one negative (0). The filter looks like so related_params[distro.id] = table.objects.filter( ProductId__in=[map["ProductId"] for map in related_maps_by_distro.values("ProductId")]).annotate( has_agr_param=Count( models.Case( models.When(DistributionParameterId__Code__in=[agr_parameter.Code for agr_parameter in agr_parameters], then=1), default=0, output_field=models.IntegerField(), ) ) ).order_by("DistributionParameterId__Name") where everything works just fine except for the annotate part. Values of [agr_parameter.Code for agr_parameter in agr_parameters] are ['ZARIZENI', '443', '10071', 'PC4.12', 'PC4.121', 'PC4.6', 'PC3.101', 'AIO 2.1'] while all possible DistributionParameterId__Codes are ['10176', '10175', '10171', '10177', '563', '10172', '10179', '829', '10174', '10173', '10170', '10178'] so there is only one match - 10071 - and therefore all but one should be annotated with 0. What am I missing? Any help would be appreciated. -
