JSONField doesn't allow null in Django 3.1
I'm trying to use a JSONField in Django, sometimes I need it be null so I defined it with null=True, blank=True, but when I'm validating with the Serializer I'm getting my_data: [This field can't be null]. Here is my code: models.py class MyModel(models.Model): my_data = models.JSONField('data', null=True, blank=True, editable=False) serializer.py class MyModelSerializer(serializers.ModelSerializer): my_data = serializers.JSONField() class Meta: model = MyModel fields = '__all__' view.py def save_my_data(self, request) info['my_data'] = None serializer = serializers.MyModelSerializer(data=info) # validate the data print( serializer.is_valid() ) #returns False print( serializer.errors ) #returns my_data: [This field can't be null] Any suggestions about this? Thanks in advance. -

Strange API response in DRF - works on server run, empties on reload

make django forgot password forms in the same page
django has 4 views for forgetting the password i want to use those views in one template so that the user don't have to go to a different URL to reset his password or type his email to send the link of resetting the password i think i just need 2 views which are the form views, first is "PasswordResetView" and the other is "PasswordResetConfirmView" the other two are views that renders templates telling the user that the email is sent successfully or the password has been reset , i don't need them i'll be replacing them with toasts i thought of copy pasting the source code of those views in my views.py but is there a more proper way to do that? for now this is how i'm rendring them each one in a diffrent path and template path('password_reset/', auth_views.PasswordResetView.as_view(template_name="main/password_reset.html",form_class=UserPasswordResetForm),name="reset_password"), path('password_reset_sent/', auth_views.PasswordResetDoneView.as_view(template_name="main/password_reset_sent.html"),name="password_reset_done"), path('reset_password/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name="main/reset_password.html",form_class=UserSetPasswordForm),name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name="main/reset_password_complete.html"),name="password_reset_complete"), -
Docker-Compose container continuosly exits with error code 247
I'm currently trying to create a Django web server using Docker. When I run the Django webserver locally, by using python manage.py runserver 0.0.0.0:8000, everything works fine. This problem occurs when running the server using docker-compose up. The container starts and dis "Watching for file changes with StatReloader" message than hangs up there for a minute or two then exits. I've tried adjusting the amount of RAM and CPU cores available to docker and that hasn't fixed the problem. Any ideas on what could be causing this and how to fix it? -

How to generate UUID paths in views.py in Django?

Django modelformset how to redirect if the instances already exist
I am using a modelformset_factory to create multiple instances. Now when the user goes back to the page and the existing instances populate the forms, if the user clicks on submit, the error shows up that the instances already exist triggered by a unique_together constraint. formset_errors [{'__all__': ['course with this instructor, location, program already exists.']}, {'__all__': ['course with this instructor, location, program already exists.']}, {}] I'd like to redirect the user to a listview to display those instances and set a message that we did not create the instances as they already are in the database. How do I do that? Right now, I am using the following which is not the best: redirect_already_exists = True for form_error in formset_errors: # list of dictionaries if form_error.get('__all__'): error_message = form_error['__all__'][0] if 'already exists' not in error_message: redirect_already_exists = False if redirect_already_exists: redirect_page = reverse('course:list_courses', args = (program_id,)) return HttpResponseRedirect(redirect_page) -

Enforce that only certain attributes can be changed using a PUT request in Django
I want to make it so a user is able to update only certain attributes with a PUT request in my Django Rest API. As an example, if I had the following model and only wanted the user to be able to update their first and last name, how would I go about doing this? models.py: class User(models.Model): email = models.EmailField('email address', unique = True) first_name = models.TextField(max_length = 10) last_name = models.TextField(max_length = 20) (noting that they should not be able to change the 'id' field either which is automatically set) serializers.py: class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ['id', 'email', 'first_name', 'last_name'] views.py: class SingleUser(APIView): def put(self, request, user_id): user = User.objects.get(pk = user_id) serializer = UserEditSerializer(user, data = request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status = status.HTTP_200_OK) return Response(serializer.errors, status = status.HTTP_400_BAD_REQUEST) What is the best way to enforce that users can only change a subset of these attributes?

Tailwind broke Vue templates (cdn)
I'm building a web app with Django and wanted to utilize Tailwind (https://tailwindcss.com/docs/installation) I followed the instructions to set up tailwind and its working fine. However, all of a sudden, my Vue templates are not being rendered properly. In my template, all I see is [[data]]instead of the actual variables? My Vue tag looks like this: (I'm using Vue through a CDN, not the CLI) var app = new Vue({ delimiters: ['[[', ']]'], el: '#app', data: { text: "something" } }) In my django template, I tried: [[text]] {% verbatim %} {{text}} {% endverbatim %} without success. All I see in the template, no matter what is just [[text]] Interestingly enough - the functions themselves work fine. E.g mounted() { console.log("test") } actually prints the message to the console, so nothing wrong with the Vue setup I guess -
Complex Django ORM Annotations & Aggregations
I'm currently preparing some logged items into a JSON serialized format. I am attempting to do this via Django's built-in ORM, utilising annotations and aggregations. I'm trying to replicate the following structure per each of these "logged items": ... { "count": 20, "metric-type": "total-dataset-requests", "access-method": "regular", "country-counts": { "au": 6, "jp": 1, "us": 13 } } ... I've currently built this queryset from my own knowledge: metrics = LoggedItem.objects.filter( identifier=record['identifier'], hit_type='investigations', is_machine=False, is_robot=False ).values( 'identifier', 'country' ).annotate( count=models.Count('identifier'), metric_type=models.Value("total-dataset-requests", output_field=models.CharField()), access_method=models.Value("regular", output_field=models.CharField()) ) This gives me a <Queryset []> as follows: <QuerySet [{'identifier': '10.80519/954e-4db4', 'country': 'fr', 'count': 1, 'metric_type': 'total-dataset-requests', 'access_method': 'regular'}, {'identifier': '10.80519/954e-4db4', 'country': 'gb', 'count': 5, 'metric_type': 'total-dataset-requests', 'access_method': 'regular'}]> As you can see, I have all of the data I need for mimicking the above data stucture. But in a sightly obscure format ... I can go in a clean this up with Python, from a values_list() or iterator(), but I'd like to do most of the heavy lifting on the database layer via the ORM. So I guess my question is, how could I replicate the kid of aggregation as shown in the JSON structure as an ORM query...? FYI: It would likely be useful to … -
