DRF POST giving NOT NULL constraint failed

Django + Mongodb : Subsetting data in the backend/frontend(template)
My django app pulls raw facebook data from a mongodb database (via djongo/pymongo) and run its through a series of internal data pipelines. At my dashboard.html page, I'm displaying some metrics(posts count, likes count etc..) for the past 7days. Everything works fine up to this point. Now I would like to let the user select from a dropdown menu list whether "past 7 days" or "past 14 days" should be displayed. Obs: It seems that I can't simply use QuerySet because the data being displayed needs to be processed in different pipelienes in the backend before rendering. Obs2: As of now I have some duplicated code in my view in order to get "7 days data" and "14 days data". I would like to simplify that. Obs3: Perhaps Ajax could be a way to go (avoid caching delay/page refresh) but I can't figure out a way to implement that. Thank you in advance!! my views.py: @login_required def dashboard(request): # Mongodb connection this_db = DatabaseFb( 'xxxxMyMongodbConnectionxxx', 'mydbname') collection_posts = this_db.collections('fb_posts') collection_comments = this_db.collections('fb_comments') # ####### Past 7 days FB data ################# this_puller_7d = DataPullerFB(collection_posts, collection_comments, past7days) posts_7d = this_puller_7d.posts_data_puller() comments_7d = this_puller_7d.comments_data_puller() this_dataprep_posts = DataPrepPosts(posts_7d) df_posts_7d = this_dataprep_posts.to_timeseries() this_dataprep_comments = DataPrepComments(comments_7d) … -
Azure App Services: Stopping site MYSITE because it failed during startup
I had my Django web app running on the Azure App Services using a single docker container instances. However, I plan to add one more container to run the celery service. Before going to try the compose with celery and Django web app, I first tried using their docker-compose option to run the Django web app before including the compose with celery service. Following is my docker-compose configuration for Azure App Service version: '3.3' services: web: image: azureecr.azurecr.io/image_name:15102020155932 command: gunicorn DjangoProj.wsgi:application --workers=4 --bind 0.0.0.0:8000 --log-level=DEBUG ports: - 8000:8000 However, the only thing that I see in my App Service logs is: 2020-10-16T07:02:31.653Z INFO - Stopping site MYSITE because it failed during startup. 2020-10-16T13:26:20.047Z INFO - Stopping site MYSITE because it failed during startup. 2020-10-16T14:51:07.482Z INFO - Stopping site MYSITE because it failed during startup. 2020-10-16T16:40:49.109Z INFO - Stopping site MYSITE because it failed during startup. 2020-10-16T16:43:05.980Z INFO - Stopping site MYSITE because it failed during startup.

I have a postgres database that recives data each 10 mins, and its been working fine for a while, and now I´m working on a Django proyect that needs to be connected to that database, and I thing the conection its ok since I can query the data, but there is a problem with the data base, at the moment I run python manage.py runserver 0.0.0.0:8100 (it needs to be in that port), the database stops reciving the data and when I stop the server the db can recive the data again, but the data that was supposed to be in while the server was running was lost.

Scipy, Scispacy, Django, Docker Issue
Having issues with scipy and numpy. This code, part of a Django app, runs perfectly when run on my windows 10 system: try: # sparse_load is a scipy.sparse.csr_matrix sparse_load = scipy.sparse.load_npz(cache) logger.info('Got sparse_load') concept_alias_tfidfs = sparse_load.astype(numpy.float32) except: logger.exception('Something went wrong!' ) # code continues here ... It also runs perfectly when running inside a docker container deployed on a Linux server. The issue is that the type conversion (sparse_load.astype(numpy.float32)) crashes my app when running in a docker container deployed on Docker Desktop running on Windows 10. The strange thing is that logger.exception is never executed! I've tried other type conversions with the same result and also tried removing the astype altogether which resulted in another crash further down in the code (again w/o hitting the exception handler placed around that piece of code. Thoughts? -

django migrate raises IntegrityError
We've been working on a django project and just run into a nasty problem with the django ./manage.py migrate command raising django.db.utils.IntegrityError during post-migration. What's interesting is that ./manage.py test works just fine. The test command creates a testing database and runs ./manage.py makemigrations && ./manage.py migrate. This would suggest we've botched something pretty good in our database, but we're having difficulty figuring out what. Here's the full stack trace. Has anyone else bumped into this sort of error? Note: The IntegrityError is caused by the migrate command attempting to insert a new record into the django_content_type table. It is providing the app_label and model column values, but not providing value for the name column which violates the non-null constraint. One other piece of potentially relevant information is that this project has a custom field. Running migrations: No migrations to apply. Running post-migrate handlers for application utils Traceback (most recent call last): File "/home/jim/src/dc/.pyenv/lib/python3.8/site-packages/django/db/backends/utils.py", line 84, in _execute return self.cursor.execute(sql, params) psycopg2.errors.NotNullViolation: null value in column "name" violates not-null constraint DETAIL: Failing row contains (46, null, utils, testutilsguidfield).

Django Template If does not work as expected
i'm trying to create a HTML drop-down with Django that shows the numbers 1 - 250 in the template and always selects the last selection after reloading the page. For this i use a variable "clea" to get the value with "request.GET.get('clea')" from the url in my "views.py" to pass it as context. To select the value in the drop-dwon I have the following syntax: <label style="color: white;">Amount</label> <select class="browser-default" id="clea"> {% for _ in ''|center:250 %} <script>console.log("{{ forloop.counter }}" == "{{ data.VIEW.clea }}")</script> {% if "{{ forloop.counter }}" == "{{ data.VIEW.clea }}" %} <script>console.log("Worked")</script> <option value={{ forloop.counter }} selected> {{ forloop.counter }} </option> {% else %} <option value={{ forloop.counter }}> {{ forloop.counter }} </option> {% endif %} {% endfor %} <script>console.log("Finished")</script> </select> Everything works except the If Statement from Django Template! In the log you can see that it always logs false, except if forloop.counter and data.VIEW.clea are equal, then its true, as expected.

I am trying to save my Server generated file in s3bucket: this is example code: from PyPDF2 import PdfFileWriter output = PdfFileWriter() newReport = open( os.path.join( settings.MEDIA_ROOT, "VISION/{}.pdf".format( bill_obj.company, bill_obj.installation_number ), ), "wb", ) output.write(newReport) newReport.close() Currently, my s3bucket is working very well but my server-generated file is not saving s3bucket. DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' AWS_ACCESS_KEY_ID=os.getenv("AWS_ACCESS_KEY_ID") AWS_SECRET_ACCESS_KEY=os.getenv("AWS_SECRET_ACCESS_KEY") AWS_STORAGE_BUCKET_NAME=os.getenv("AWS_STORAGE_BUCKET_NAME") AWS_S3_REGION_NAME =os.getenv("AWS_S3_REGION_NAME") As i showed how i saving the PDF in local machine but i want to save this in s3bucket. How can i do it? -
Django annotate field value from another model
I want to annotate MyModel queryset with a value from another History model. My models relations are the following: class Stage(models.Model): name = models.CharField() class History(models.Model): mymodel = models.ForeignKey( MyModel, on_delete=models.CASCADE, ) stage = models.ForeignKey( Stage, on_delete=models.DO_NOTHING ) created_at = models.DateTimeField( auto_now_add=True ) class MyModel(models.Model): id = models.AutoField( primary_key=True, ) ... Approximate operation I'd like to perform in the ViewSet (order_by I need to get the latest stage): class MyModelViewSet(viewsets.ModelViewSet): ... def get_queryset(self): qs = super(MyModelViewSet, self).get_queryset() qs = qs.annotate(last_stage_name=Value( History.objects.filter(mymodel__id=F('id')).order_by('-created_at')[0].stage.name, output_field=CharField())) But I get the same stage for all objects from the first object instead of the latest stage of every object, so the logics of operation is wrong. I suppose I should get rid of History.objects.filter but can't find appropriate solution. -
