Get Django to return related objects
I'm trying to filter one table and obtain the related rows from another table as a nested object. Models are as follow: class KpiArea(models.Model): harvest = models.CharField(max_length=45) area_id = models.IntegerField() percentage = models.FloatField(max_length=10) class Meta: managed = False db_table = 'kpi_area' unique_together = ['harvest', 'area_id'] class KpiAreaProducts(models.Model): product = models.CharField(max_length=45) percentage = models.FloatField(max_length=10) area_id = models.IntegerField() harvest = models.ForeignKey(KpiArea, on_delete=models.PROTECT, db_column = "harvest") class Meta: managed = False db_table = "kpi_area_products" unique_together = ['harvest', 'area_id'] My goal would be to be able to get the related objects whenever I'm filtering on KpiArea, ideally as a property containing a related object's array. Something like this: [ { area_id : 1, harvest: '2020/2021', percentage: 25, products: [ { product: 'soy', percentage: 15, area_id : 1 }, { product: 'wheat', percentage: 35, area_id : 1 }, ] } ] I've tried linking with 2 foreing keys on KpiAreaProducts model, and unique_together (as per other SO questions) to achieve this. Could somebody point me in the right direction? -
Django TestCase fails to load fixture data with MySQL
I am trying to create tests to check a newly implemented login process, however I got stuck at the very beginning. When I try to make a query in my tests, Django throws a MySQLdb._exceptions.OperationalError and fails to continue. I noticed, that this issue happens only when I use django.test.TestCase, but not when I use django.test.TransactionTestCase. Now I read that there is a difference between how these two handle transactions, but I still cannot understand why one fails when the other one works. Can someone please point me in the right direction? This code fails: class AuthenticateUserTest(TestCase): fixtures = ["test_users.json"] serialized_rollback = True def test_login_success(self): print(User.objects.all()) but this code doesn't: class AuthenticateUserTest(TransactionTestCase): fixtures = ["test_users.json"] serialized_rollback = True def test_login_success(self): print(User.objects.all()) with this fixture: [ { "model": "app.user", "pk": 1, "fields": { "created_at": "2022-04-07T13:34:53+01:00", "email": "test@test.com", "password": "topsecret", "is_active": true, "roles": "[\"SUPER_ADMIN\"]", "first_name": "Test", "last_name": "User" } } ] and with the following error: ERROR: test_login_success (tests.auth.test_auth_api.AuthenticateUserTest) ---------------------------------------------------------------------- Traceback (most recent call last): File "/app/tests/auth/test_auth_api.py", line 36, in test_login_success print(User.objects.all()) File "/usr/local/lib/python3.8/site-packages/django/db/models/query.py", line 252, in __repr__ data = list(self[:REPR_OUTPUT_SIZE + 1]) File "/usr/local/lib/python3.8/site-packages/django/db/models/query.py", line 258, in __len__ self._fetch_all() File "/usr/local/lib/python3.8/site-packages/django/db/models/query.py", line 1261, in _fetch_all self._result_cache = list(self._iterable_class(self)) File "/usr/local/lib/python3.8/site-packages/django/db/models/query.py", line … -
Django add a field to a model based on another model
I have a model for a product: class Product(models.Model): name = models.CharField(verbose_name=_("Name"), max_length=120) slug = AutoSlugField(populate_from="name", verbose_name=_("Slug"), always_update=False, unique=True) I want to have a separate model ProductFields: class ProductFields(models.Model): field_name = models.CharField() field_type = models.CharField() field_verbose_name = models.CharField() field_max_length = models.IntegerField() filed_null = models.CharField() field_blank = models.BooleanField() field_default = models.CharField() ... So the idea is whenever I add new ProductField I want Product model to migrate that added field to its database. For Example: ProductFields.objects.create(field_name='description', field_type='CharField', field_verbose_name='Description', field_max_length=255, filed_null=True, filed_blank=True) This should transform Product modal to: class Product(models.Model): name = models.CharField(verbose_name=_("Name"), max_length=120) slug = AutoSlugField(populate_from="name", verbose_name=_("Slug"), always_update=False, unique=True) description = models.CharField(verbose_name="Description", max_length= 255, null=True, blank=True) Please let me know if you have any idea how this can be done? -

How to call double nested reverse foreign key relation in django?
I'm working on forum project. Currently, I need to fetch somehow the latest posts for each category. My models structure is following (pseudo code): class Category(models.Model): ... class Topic(models.Model): category = models.ForeignKey(Category, on_delete=models.CASCADE) ... class Post(models.Model): topic = models.ForeignKey(Topic, on_delete=models.CASCADE) ... I need to fetch latest Post objects within Category model's functions, so I can call it latter on in my template. With single reverse foreign key call I would do something like: category: Category = self.topic_set.all() but I need to get one level deeper for Post. Is there any smarter way to do it instead of list comprehension like [topic.post_set.first() for topic in self.topic_set.all()] ?? -

Connect two Django models
Hi! I'm trying to make a auctions website for a project and I can't get to connect 2 models I have in my models.py page, a model for the auction listings (Alisting) and a model for the bids that are made(Bid). -The Alisting model has 4 fields: "title" CharField for the title of the auction, "sta_bid" for a starting bid, "las_bid" ForeignKey to Bid model, and user ForeignKey to User. -The Bid model has 3 fields: "user" ForeignKey to User for the user that makes the bid, "listing" a ForeignKey to Alisting, and "new_bid" IntegerField for the latest bid. class User(AbstractUser): pass class Alisting(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=32) sta_bid = models.IntegerField() las_bid = models.ForeignKey(Bid, on_delete=models.CASCADE) class Bid(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) listing = models.ForeignKey(Alisting, on_delete=models.CASCADE) new_bid = models.IntegerField() How could I connect these 2 models so that when I create a listing I can create new bids to this listing from the other model. Because later in the project I'll have to allow users to modify bids from other user's listings. Thank you in advance! -
Saving data to Django database with Views
I need help with one thing in my django project. I have class games_renderer in my views.py which is connected to the path in URLs. I need this class to take three values and then store them in the SQL database in Django in the created UserGameScore model. I tried to do this using model.object.score but the application reports an error. I think the problem is that the application does not know which line to assign the value to, but I do not know where I can determine this value, using the value player_id. The Game_id value is used to specify in which column the value is to be written.Can anybody help me, it is urgent! views.py def games_renderer(request, game_id, player_id, score): if game_id == 1: UserGameScore.objects.create(game1_score = score) elif game_id ==2: UserGameScore.objects.create(game2_score = score) elif game_id ==3: UserGameScore.objects.create(game3_score = score) else: return render(request, 'result.html',{'game_id' : game_id, 'player_id' : player_id, "score" : score} ) models.py class UserGameScore(models.Model): user_rec = models.ForeignKey(User, on_delete=models.CASCADE) game1_score = models.IntegerField(null=True, blank=True) game2_score = models.IntegerField(null=True, blank=True) game3_score = models.IntegerField(null=True, blank=True) -

Django ORM prefetch field from manual join table on many-to-many relationship

I find I'm needing to do DashboardItem.objects.filter(item=item,dashboard=dashboard).first().combo_hash How do I prefetch values on the manual through table when I load the dashboard or item? -

Tastypie: How can I create an "abstract" ModelResource class with a Meta class
Using django-tastypie I'd like to create a child class of ModelResource to define some common things, which all my other API resource classes would inherit from. e.g.: class MyModelResource(ModelResource): class Meta: authentication = SessionAuthentication() authorization = APIAuthorization() always_return_data = True # Some other common methods here class UserResource(MyModelResource): class Meta(MyModelResource.Meta): queryset = User.objects.all() However, if I do this, I get the following error: django.core.exceptions.ImproperlyConfigured: ModelResource (MyModelResource) requires Meta.object_class or Meta.queryset So I must set object_class or queryset in MyModelResource.Meta, even though it's a kind of 'Abstract' class.

Rendering local web pages as an iFrame in Django

Using templatetag "get_comment_list" from view, in Django comments?
I have a template expression {% get_comment_list for data.post as comment_list %}, it uses get_comment_list from Django-comments. It gets a list of comment objects for a specified object (in this case the Post object through data.post) However, I'm currently working on client side Ajax API to retrieve the comments and its related user data. So I cannot use the template html way to get/render the data, but in a view, Python script. I found that the tag get_comment_list is defined as follows: # django_comments/templatetags/comments.py @register.tag def get_comment_list(parser, token): return CommentListNode.handle_token(parser, token) I know how to import custom template tag to a view so Python can use it, like: @register.simple_tag def addFoo(value=""): return value + "Foo." The above type of tag is simply passing a string value, but the get_comment_list(parser, token) tag requires two parser thing and object thing object, it's not a plain string type. Now, I have no idea how I can construct that parser and token or pass a model to get_comment_list to get the comment objects. Is it possible to use this type of template tag in a view? Thanks. -

As example I have { "id": 1, "status_timestamp": "2022-04-07T10:51:42Z", "status_activity": "Sync DDT", "status_status": "running", "launcher": 1 } and I need to obtain this (in the DB) via API { "id": 1, "status_timestamp": "2022-04-07T11:51:42Z", "status_activity": "Sync DDT", "status_status": "completed", "launcher": 1 } Can someone help me out? PS I need to mantain the Token authentication method MODELS class JobStatus(models.Model): status_timestamp = models.DateTimeField() status_activity = models.CharField(max_length=200) status_status = models.CharField(max_length=200) launcher = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.RESTRICT) class Meta: verbose_name = "Status" verbose_name_plural = "Status list" def __str__(self): return str(self.status_timestamp) + " " + self.status_activity URLS from django.urls import path, include from apps.api_c import views from rest_framework.routers import DefaultRouter from rest_framework.urlpatterns import format_suffix_patterns router = DefaultRouter() router.register('alert', views.AlertViewSet) router.register('jstatus', views.UpdateStatus) urlpatterns = [ ... path("", include(router.urls)), ] VIEWS class UpdateStatus(viewsets.GenericViewSet, mixins.ListModelMixin, mixins.RetrieveModelMixin, mixins.UpdateModelMixin): """update status""" authentication_classes = (TokenAuthentication,) permission_classes = (IsAuthenticated,) serializer_class = StatusSerializer #queryset = JobStatus.objects.all() #TEST1 def put(self, request, *args, **kwargs): return self.update(request, *args, **kwargs) #TEST2 def perform_update(self, serializer): serializer_class.update() -
Class-Based View of 'User' model auto-authenticates user
I've made a class-based view (DetailView) of app user's profile and for some reason anyone who visits the view is automatically considered authenticated even without entering any credentials. This happens without adding any extra logic in neither view nor template, just basic DetailView. The code is below: views.py from django.views.generic import DetailView from django.contrib.auth.models import User class ProfileDetail(DetailView): model = User template_name = 'index.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) return context urls.py from django.urls import path from .views import ProfileDetail urlpatterns = [ path('<int:pk>/', ProfileDetail.as_view()) ] template (index.html) {{ user.is_authenticated }} {# returns True #} {{ user }} {# returns the user with the corresponding id #} The question is why does Django do it and is there any way to circumvent it except of using function-based view? I've looked through the docs, but couldn't find an answer.
