Efficiently updating a large number of records based on a field in that record using Django
I have about a million Comment records that I want to update based on that comment's body field. I'm trying to figure out how to do this efficiently. Right now, my approach looks like this: update_list = [] qs = Comments.objects.filter(word_count=0) for comment in qs: model_obj = Comments.objects.get(id=comment.id) model_obj.word_count = len(model_obj.body.split()) update_list.append(model_obj) Comment.objects.bulk_update(update_list, ['word_count']) However, this hangs and seems to time out in my migration process. Does anybody have suggestions on how I can accomplish this? -
Django Related Through Models Not Using Soft Delete Model Manager
i am trying to retrieve only rows in a through model that are not deleted but keep getting all rows including the deleted ones. learnt it's a bug with using use_for_related_fields in the model manager according to this link: https://code.djangoproject.com/ticket/17746 i am trying to implement a follow/unfollow system like on social media platforms below is my code sample class BasicModelQuerySet(models.QuerySet): def delete(self): return self.update(is_deleted = True, deleted_at = timezone.now()) def erase(self): return super(BasicModelQuerySet, self).delete() class BasicModelManager(models.Manager): use_for_related_fields = True def get_queryset(self): return BasicModelQuerySet(self.model, self._db).filter(is_deleted = False).filter(deleted_at__isnull = True) class BasicModel(models.Model): deleted_at = models.DateTimeField(blank = True, null = True) is_deleted = models.BooleanField(default = False) objects = BasicModelManager() everything = models.Manager() class Meta: abstract = True class Listing(BasicModel): watchers = models.ManyToManyField(User, through = 'Watching', related_name = 'watchers') class Watching(BasicModel): user = models.ForeignKey(User, on_delete = models.RESTRICT, related_name = 'watching') listing = models.ForeignKey(Listing, on_delete = models.RESTRICT, related_name = 'spectators') sample tables id | user | ------------- 1 | User A | 2 | User B | id | listing | ---------------- 1 | Listing A | 2 | Listing B | # watchings table id | user | listing | deleted_at | is_deleted | ------------------------------------------------------------ 1 | User A | Listing A | | … -

Django Model method that uses data from the model
I want to generate unique codes (e.g. "DXGH") and save it as a field in one of my models. The problem I have is that I do not know how to check against previously generated codes whenever a new object is created. Currently my models.py looks something like this: def code_gen(): random_string = '' for _ in range(4): random_string += chr(random.randint(97,122)) return random_string class Room(models.Model): room_code = models.CharField(default=code_gen) #other fields def __str__(self): return self.room_code #other methods def code_gen_unique(self): #I know the code below is incorrect code_list = [] for object in Room.Objects.all(): code_list.append(object.room_code) while True: temp_code = code_gen() if temp_code in code_list: continue break return temp_code Ideally I would set the default value of room_code to code_gen_unique, but I can't declare code_gen_unique() before my Room class, nor after it. I expect there is a much easier solution than I have considered, and would appreciate any help very much! Cheers -
Is there a way to access a private .zip S3 object with a django app's .ebextension config file deployed on elastic beanstalk
We have a django app deployed on elastic beanstalk, and added a feature that accesses an oracle DB. cx-Oracle requires the Oracle client library (instant client), and we would like to have the .zip for the library available as a private object in our S3 bucket, public object is not an option. We want to avoid depending on an Oracle link with wget. I am struggling to develop a .config file in the .ebextensions directory that will install the .zip S3 any time it is deployed. How can was set-up the config to install on deployment? os: Amazon Linux AMI 1 -
Import & Export Django Package Foreign Key CSV File Import Issue
I'm trying to import scores for student data and I keep getting the error message that the query doesn't match on the import. I tried designating the import to look at the state_province field as the foreign key, but I don't think I have it written correctly. Secondly for some reason on my date field keeps failing the null constraint which I'm not understanding why since the excel file data is in the correct format. I set in the model null=true for now to bypass.Here is my code. I appreciate the help.

How to correctly use Fetch in JavaScript and Django?

Django makemessage not updating .po files for installed apps
I'm working with a current project that has existing .po files in "locale" directories in multiple installed app directories. Currently each locale directory is explicitly mentioned in the LOCALE_PATHS even though the docs state it will search for locale directories in each installed app. I wanted to remove the values in LOCALE_PATHS and just let normal discovery work, but it's not working. If I clear out LOCALE_PATHS and run manage.py makemessages it appears like it's doing something (time is spent processing), but no file changes occur. If I do makemessages --keep-pot then I can see all the .pot files are actually being created, but it's not actually creating the .po files for each language. Only if I explicitly pass a -l de do I then get an updated .po file for the language stated and a message stating "processing locale de". It SHOULD be able to look at the LANGUAGES setting or what files already exist and properly update them, but that appears to only happen if every locale directory is explicitly added into LOCALE_PATHS. If I have all the locale paths in LOCALE_PATHS then I can just run manage.py makemessages and all .po files are properly updated. This is … -

Proper way to create django rest endpoint without model

It will find necessary data in already created database to perform calculation and then it should return calculation result as response.

It works but you know :) urls.py schema_view = get_schema_view( openapi.Info( title="API Test", default_version='0.0.1', description="Test", ), public=True, ) urlpatterns = [ path('docs/', schema_view.with_ui('redoc', cache_timeout=0), name='schema-redoc'), path('equation/1/example', EquationView.as_view()), #... more paths to other equations... ] view.py def get_emission_val(req_emiss_fac): try: return Emission.objects.get(emission_factor=req_emiss_fac) except Emission.DoesNotExist: raise Http404("Emission value does not exist in database") equation_response = openapi.Response('response description', EquationResponseSerializer) @swagger_auto_schema( query_serializer=EquationRequestSerializer, responses={ '404':'Emission factor does not exist in database', '200': equation_response }, ) class EquationView(APIView): def get(self, request): emission_val = get_emission_val(request.data['emission_factor']) combusted_val = request.data['combusted_value'] emissions = combusted_val * emission_val.co2_emission return Response({'emissions':emissions}) serializers.py class EquationRequestSerializer(serializers.Serializer): emission_factor = serializers.CharField() combusted_value = serializers.FloatField() class EquationResponseSerializer(serializers.Serializer): emission = serializers.FloatField() What do you think about this approach? I'm not sure if I have to do it in this way.
