Django, django-stores: File not found when using Google cloud storage
Ive created a file field on my model: class File(models.Model): """ Files added to the message. """ file = models.FileField(verbose_name=(_("File")), upload_to="mail/%Y/%m/%d") message = ParentalKey( "message.EventDetailMessage", on_delete=models.CASCADE, related_name="files" ) Im now trying to access the uploaded file and attach this to an email, but I cant get it to work reliably in production and locally. Right now its always working locally, but I cant seem to access the file in production (which uses django-stores with GOOGLE settings, since I use Google cloud buckets). When running the code below in production I get the message: "File was not found" for message_file in message.files.all(): logger.info(f"Attaching file {message_file}") file = message_file.file email.attach(basename(file.name), file.read(), guess_type(file.name)[0]) file.close() Can anyone point me in the right direction? -

What "command" does Celery's app.control.broadcast expect?
I thought that app.control.broadcast would take an @task, but when running the following: app.send_task("workerTasks_supervisor.task_supervisor_test", args=[], queue='supervisor') app.control.broadcast("workerTasks_supervisor.task_supervisor_test", args=[], queue="supervisor") The first succeeds and the second fails with: [2019-08-01 12:10:52,260: ERROR/MainProcess] pidbox command error: KeyError('task_supervisor_test',) Traceback (most recent call last): File "/usr/local/lib/python3.5/dist-packages/kombu/pidbox.py", line 104, in dispatch reply = handle(method, arguments) File "/usr/local/lib/python3.5/dist-packages/kombu/pidbox.py", line 126, in handle_cast return self.handle(method, arguments) File "/usr/local/lib/python3.5/dist-packages/kombu/pidbox.py", line 120, in handle return self.handlers[method](self.state, **arguments) KeyError: 'task_supervisor_test' The worker is started with celery worker -A workerTasks_supervisor -n Supervisor --concurrency=1 --loglevel=info -Q supervisor -f /logs/celery_supervisor.log --pidfile=/logs/supervisor_pid.pid And the task itself is simple: @app.task() def task_supervisor_test(): print("working") What am I doing wrong?

Conditional checks not working while processing form in Django
I have a ModelForm (EditGoalForm) which I use to edit an instance of a model (Goal). Some conditions must be met before saving form data. I used if statements to check these conditions and it still saves, instead of giving an error - like the if statement does nothing. I have the following: models.py class Goal(models.Model): goal_name = models.CharField(max_length=250) goal_status = models.ForeignKey(GoalStatus, on_delete=models.CASCADE, related_name='goal_status') user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='scrumy_goal_user') class GoalStatus(models.Model): status_name = models.CharField(max_length=250) forms.py class EditGoalForm(forms.ModelForm): goal_status = forms.ModelChoiceField(queryset=GoalStatus.objects.all(), empty_label="Select Goal Status") class Meta: model = Goal fields = ('goal_status',) views.py def move_goal(request, goal_id): goal_instance = Goal.objects.get(goal_id=goal_id) ERROR_MESSAGE = '''BlahBlahBlah''' has_perm_cannot_move_to_done = request.user.has_perm('application.cannot_move_to_done') has_perm_can_move_goal_anywhere = request.user.has_perm('application.can_move_goal_anywhere') has_perm_can_move_someones_goal_from_verify_to_done = request.user.has_perm('application.can_move_someones_goal_from_verify_to_done') has_perm_can_move_anybodys_goal_to_any_column = request.user.has_perm('application.can_move_anybodys_goal_to_any_column') if request.method == 'POST': form = EditGoalForm(request.POST, instance=goal_instance) if form.is_valid(): if (has_perm_cannot_move_to_done and form.cleaned_data['goal_status'] != 'Done Goal'): form.save() messages.success(request, 'Goal Update Successful') return redirect('home') else: messages.error(request, ERROR_MESSAGE) else: form = EditGoalForm(instance=goal_instance) return render(request, 'move_goal.html', {'form': form}) After if form.is_valid, I checked if the authenticated user has the permission and if the goal_status field was not set to Done Goal.

How can I get the keycloak ID using mozilla-django-oidc using django?
I'm using mozilla-django-oidc for my keycloak authentication with django. I can only retrieve the user email from this but can't get the other credentials like username, id etc. From keycloack config it should have in this key value pair: "claims_supported":["aud","sub","iss","auth_time","name","given_name","family_name","preferred_username","email"] but as I'm using this package I'm really confused how can I get the id means sub from it. This is my view file where i want to show the user id of the logged in user: views.py <html> <body> {% if user.is_authenticated %} <p>Current user: {{ user.email}}</p> {# shows the user email #} <p> username {{ user.sub) }}</p> {# but doesn't show the user id #} <p>Secured</p> {% else %} <a href="{% url 'oidc_authentication_init' %}">Login</a> {% endif %} </body> </html> -
Using django custom manager method as part of Q object chain
I have a custom manager with a method: # managers.py class MyModelQuerySet(models.QuerySet): ### def close_matched(self, radius=5): return self.filter( matched=True, separation__lte=radius, ) Is there anyway to use the filtering in close_matched with a set of Q object filters, for use in a view? As a simple example, something like: q = Q(another_constraint=True) | MyModel.objects.close_matched(4) but with a corrected object on the right side of the | (currently gives a TypeError since it is a queryset). If not, I'm not sure what would be best practice here to avoid duplicating the code whereywhere, is it best to rewrite the filtering logic of close_matched as a Q object that I can call in close_matched and elsewhere in views.py etc.? -
Http failure response for Django local server: 0 Unknown Error
I can see that there are several questions with this same error, I have read many of them and most are related to CORS problem. In fact, my browser is also generating CORS related warnings. I had this same problem a while ago and managed to solve by reconfiguring the header of my application. Now I'm using the same configuration, but for a different server, and I can't get over this error. I have an Ionic v4 app running in port 8100 and my Django v2.2.4 server is running in port 8000.

Django: Retrieving the private key of selected dropdown option in Ajax call

I thought I would be able to it this way: var scenario_id = document.getElementById("scenario-dropwdown").value But looking in the console, I get Uncaught TypeError: Cannot read property 'value' of null, so clearly it's not working - likely with respect to the <form>.

Django: Save objects with circular references
I'm using Django with the PostgreSQL backend. Now, I've two models with circular references: Thread exists of a startpost of type Post Post exists of a thread of type Thread My problem is that I cannot create any of the two objects because they are dependent on each other. One solution to that problem is the DEFERRABLE INITIALLY DEFERRED constraint that is also supported by PostgreSQL. After some research I found the following post: https://www.reddit.com/r/django/comments/72qwr6/why_does_the_postgresql_backend_make_foreignkeys/ So it looks like that Django also supports this and, as long as you create your objects in a transaction, it should work. However, when I test it I get an IntegrityError, it looks like my Django did not create the DEFERRABLE INITIALLY DEFERRED constraint. I'm confused. Can someone clarify the situation? Did I miss something? -

Unable to Pass SQL Object From Python to Javascript in Django
I am trying to send a single SQL object to my Javascript in Django using json.dumps however I get the error: Object of type List is not JSON serializable when I run the following code: user_data = List.objects.get(user=request.user.username) context['list'] = json.dumps(user_data) return render(request, "template.html", context) The SQL Object has three fields, the first is a username and the other two are lists. Please can you tell me how to convert this to JSON correctly. -
