There has been a 500 error on the Your Platform Name Here servers - Django/Openedx
Kindly help me out. Mistakenly I deleted 'example.com' which was default site using Django administration web interface and there is no other site available.. Now while restarting the server, it ended up with "There has been a 500 error on the Your Platform Name Here servers" . On google i got the solution "updating the SITE_ID property in the /opt/bitnami/apps/edx/edx-platform/lms/envs/common.py file" but it can only work if i have any site configure in Mysql database. So I want to know in which table I have to add data for configuring my site? -

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. But it will never log "Worked", although it logs "true" in the line above. Does anyone know what this could be? -
Django save severe generated file in s3bucket

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. -

How to delete the first name and last name columns in django user model?
I created a custom user model just like the docs said, when I ran the makemigrations I went to the folder of migrations and deleted the first name and last name columns inside the 0001_initial.py and then I ran the migrate command, but when I ran the createsuperuser command it throwed an error in the terminal that django.db.utils.OperationalError: no such column: myapp_usermodel.first_name How can I fix this?

Django - cooperation of two users
I'm developing a Django web app and have run into the following problem. The idea I have is to allow two users to perform an action together on the certain page - when first one enters the page the "session" is created and the server is waiting for the second user to enter. After 2nd user enters the page, they can perform a certain action together. (Basically they will take turns choosing items from available item pool, so that in the end everyone has his "basket") Could you share any resources on how to achieve this functionality with Django? Any documentation/tutorials/materials/tips what to look for will be useful. I wasn't able to find anything, but I probably don't name the problem properly. -
Access first value in tuple in Django Template HTML
I am creating a website in Django and need to display a value that the user had chosen from a choice field - their user_status which is stored in a tuple. The first and second values are identical, but they can be 'Member' or 'Expert'. At first I tried this in my HTML: {{ user.user_status }} This was the result: ('Member', 'Member') What I wanted was this: Member Next, I tried {{ user.user_status.Member }} The result was nothing: Finally I tried {{ user.user_status.Member.0 }} The result was the first character in ('Member', 'Member') ( How can I access either the first or second value of this tuple and display it in my HTML? -
Set cookies for ajax request, when "JsonResponse" is returned

The view xxx didn't return an HttpResponse object. It returned None instead
I have an error I do not understand because the logic I use in my view has not changed and works for my other project. And when I read the Django doc, my logic's view is conform: https://docs.djangoproject.com/fr/2.2/topics/forms/#the-view We call the form’s is_valid() method; if it’s not True, we go back to the template with the form. This time the form is no longer empty (unbound) so the HTML form will be populated with the data previously submitted, where it can be edited and corrected as required. In my form, I have validation control. My clean method below have 3 validations controls and the control #2 raised errors <ul class="errorlist"><li>__all__<ul class="errorlist nonfield"><li>Ce patient ne peut être randomisé dans ce site. Veuillez vérifier votre saisie.</li></ul></li></ul> So in my understanding of the doc, it should be redirected to the completed form with errors message display (as it do usually in my project) even if there is no else condition for no valid form in my view(is_valid() == False). What is wrong? views.py def randomization_edit(request): if request.method == "POST": print("request", request.POST.dict()) form = RandomizationEditForm(request, data=request.POST or None) if form.is_valid(): # do stuff return redirect('randomization:confirmation', pk=randomisation.pk) else: if request.session.get('user_can_randomize'): form = RandomizationEditForm(request) return render(request, … -
How to listen to remote SQS queue in Django app?
I have a remote SQS queue I would like to listen to in my Django app. When a new message is published on the SQS queue, I would like my Django app to pick it up and do something with it (like parse it and insert a record into the database). I'm having a bit of confusion about the best tools for accomplishing something like this. I've mainly been spinning my wheels trying to get this to work using Celery. The part I'm not able to figure out with Celery is how can I trigger a task when a new message is published. I've followed these guides from Celery: https://docs.celeryproject.org/en/stable/django/first-steps-with-django.html https://docs.celeryproject.org/en/stable/getting-started/brokers/sqs.html However, the part that is not apparent to me is how a task is called when an SQS message is published. When I fire up celery via celery -A test worker -l INFO and publish a message in AWS to my SQS queue, I can see it printed in my console. I can also see that it picked up the task I defined in Django. Now, whenever it detects a new message, I want it to call my debug_task below. import os from celery import Celery os.environ.setdefault("DJANGO_SETTINGS_MODULE", "camp.settings") app … -
