Facing a Client Error when trying to Upload an image to Amazon S3 bucket from Django website
I have recently uploaded my Django website on Heroku and the media and static files are served by Amazon S3. The static files and media files are serving well and I can see them in the website. But the problem comes when I try to Upload a profile Image in profile page. It shows a Client Error: An error occurred (InvalidAccessKeyId) when calling the PutObject operation: The AWS Access Key Id you provided does not exist in our records. My amazon s3 settings: AWS_STORAGE_BUCKET_NAME = 'oryxrating' AWS_S3_CUSTOM_DOMAIN = 's3.ap-south-1.amazonaws.com/%s' % AWS_STORAGE_BUCKET_NAME AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID') AWS_SECRET_KEY = os.environ.get('AWS_SECRET_KEY') AWS_S3_OBJECT_PARAMETERS = { 'CacheControl': 'max-age=86400', } AWS_LOCATION = 'static' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'), ] STATIC_URL = 'https://%s/%s/' % (AWS_S3_CUSTOM_DOMAIN, AWS_LOCATION) STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' DEFAULT_FILE_STORAGE = 'Oryx.storage_backends.MediaStorage' I have set amazon access id and secret key in heroku configuration variables as AWS_ACCESS_KEY_ID and AWS_SECRET_KEY and they are correctly set. Please help me as I cannot understand the problem and definitely not getting a solution. Please tell where to put the Access id so that the upload works. -
Use Key-Value Lookup for Second Model in Django Template For Loop?
I'd like to figure out a way to use a key-value lookup for a second model within a Django for loop. This question on dictionary key-value loops in templates is on the right track, but I am using two normalized data models. There is a 'Parent' data object (EventDetail) that contains the relevant link and 'Child' data object (DateEvent) that has date-specific information with data on user actions. I have a template tag, link_if_exists, that is being duplicated many times. Django-debug-toolbar tells me this is being duplicated 76 times right now. This 'duplicate' message is, itself, duplicated many times. This is what I have now: app_extras.py @register.filter() def link_if_exists(title): """Return a link if it exists""" event_link = None try: event_link = EventDetail.objects.filter(title=title).values_list('link', flat=True)[0] except IndexError: pass if event_link != "": return event_link return False template.html {% load 'app_extras' %} {% for item in child_date_items %} {% if item.title|link_if_exists %} <a href="{{item.title|link_if_exists}}">{{item.title}}</a> {% endif %} {% endfor %} models.py class DateEvent(models.Model) title = models.CharField(max_length=250) event_date = models.DateField(default=date.today) event_datetime = models.DateTimeField(auto_now=False) class EventDetail(models.Model) title = models.CharField(max_length=250) link = models.URLField(max_length=200, default="", blank=True) views.py class ProblemView(TemplateView): template_name = "template.html" def get_context_data(self, **kwargs): context = super(ProblemView, self).get_context_data(**kwargs) date_today = utils.get_date_today() child_date_items = DateEvent.objects.filter(event_date=date_today) context['child_date_items'] = … -

int() argument must be a string, a bytes-like object or a number, not 'ModelBase'
I'm fairly new to Django, and coding in general so this could be a conceptual oversight, but I'm running out of ideas so any help is appreciated. I'm trying to add logic to my form's clean() method which has nested try blocks. I'm trying to get object instances from different ForeignKey related models in each try block. The first two levels seem to work fine, but the third level throws the error below. I've printed the value and type for wine_get.wine_id and I get back 6 and 'int' respectively, so I'm not sure why this isn't considered a number.

two factor authentication on django
I would like to add two factor authentication to my django project. I made some research and found two libraries (django-two-factor-auth and drf-pyotp), but both of them have very little documentation, and my problem is that i really don't know how to implement the library on my already existing project. Are there other widely used libraries for this? Is there a tutorial or a example that i can use in order to understand it better, in order to implement my own version? Thanks in advance. -
How do I automatically set to_user (receiver) in my message form?
Models class Message(models.Model): sender = models.ForeignKey(User, related_name="sender", on_delete=models.CASCADE) reciever = models.ForeignKey(User, related_name="reciever", on_delete=models.CASCADE) title = models.CharField(max_length=50) I am pretty sure I have the right idea, and that is to first create a button: <a href="{% url 'send-message-to' profile.user.id %}" class="btn btn-primary">Send a message</a> I then pass the profile id to my CreateView and then query the user with the received pk: class MessageCreateView(CreateView): model = Message fields = ['title', 'msg_content'] def form_valid(self, form): form.instance.sender = self.request.user form.instance.receiver = User.objects.get(id=self.kwargs.get('pk')) return super().form_valid(form) But it is not working as intended. I am receiving the error IntegrityError at /messages/create/1/ null value in column "reciever_id" violates not-null constraint For some reason the code I have written is not filling in the receiver id. form.instance.receiver = User.objects.get(id=self.kwargs.get('pk')) How can I get my form to automatically set the reciever (to_user) in my form? What is happening right now is that when I try to create a message I get a dropdown of all the users available which is not desired. -
How to deal with OneToOneField admin/forms
I'm struggling to design relations between models. I'm working on a base for a big project so I'm want things to be as universal as they can. There will be more models with addresses. For example auth.User, Client, Property so I decided to create an addresses app with Address model. The same thing with contacts.ContactInformation. It's much more intuitive and modular to do this: class Client(..): address = OneToOneField('addresses.Address',on_delete=PROTECT... contact_information = OneToOneField('contacts.ContactInformation'...) Than this: class Address(..): client = OneToOneField('clients.Client',on_delete=CASCADE) Problems with 1. I can't use many built-in behaviors like admin inlines, on_delete=CASCADE etc. Address is mandatory. Problems with 2. As I mentioned, is much less intuitive for new developers and theoretically, I can't be sure that every address has either Client, User or Property. And you can't see immediately that Client has Address. So now I'm considering multiple approaches. 1. The first one is to use add_to_class so I can put all logic to one app (for example clients for Client: class Client... .... Address.add_to_class('client',OneToOneField('clients.Client',on_delete=CASCADE... I could use admin inlines, forms and everybody can clearly see that Client has Address. 2. I could create multiple Address models like ClientAddress, UserAddress which uses abstract model AbstractAddress. Do you have arguments which … -

Django: How to override verbose_name and help_text of model fields
I need some morre input/opinion on the following matter: I want to overwrite the verbose_name and help_text for all fields of certain django models. I already have a structure where these values are stored into the database. Fields are iterated through: Contract._meta.get_fields() The I use a formset with initial/default values for this fields. This is working nicely so far. My problem now is that I want to keep the default values within the value and want to override this everywhere the values are accessed (admin-forms, form, templates etc.). I think something like a Mixin although I thing then I would have to change too much of the django-code. Other possibility which already worked is to call a function instead of verbose_name and help_text e.g. title = models.CharField(max_length=120, blank=True, null=True, verbose_name=get_vname('title') help_text=get_help_text('title')) title_long = models.CharField(max_length=120, blank=True, null=True, verbose_name=get_vname('title_long') help_text=get_help_text('title_long')) But thats too much manual changes and I need to store the defaults as well. Is there a better way (DRY) to achieve this? Maybe there is an extension? -
DRF UpdateAPI View returns "detail": "Not found."
When making PUT or PATCH to my DRF endpoint I get a 404 "detail": "Not found." response. I'm not sure what is causing the error, my view or serializer. The documentation on DRF is a little lacking and there is no working example of a UpdateAPIView for me to reference. Code: urls.py path('api/update/job/<int:pk>/', views.UpdateJobView.as_view() ), serializers.py class JobsUpdateSerializer(serializers.ModelSerializer): designer_one = serializers.PrimaryKeyRelatedField(many=False, queryset=UserProfile.objects.all()) designer_two = serializers.PrimaryKeyRelatedField(many=False, queryset=UserProfile.objects.all()) class Meta: model = Job fields = '__all__' views.py class UpdateJobView(generics.UpdateAPIView): serializer_class = JobsUpdateSerializer lookup_field = "pk" def get_queryset(self): queryset = Job.objects.all() jobID = self.request.query_params.get('pk', None) if jobID is not None: queryset = queryset.filter(id=jobID) else: return False Do I need to modify my view to contain the get_object function?

Django: Media image isn't loading and a 'static/' is getting included in the path from nowhere
I have a Account model: class Account(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) profile_pic = models.ImageField (upload_to ='media/images/profile-photos', verbose_name="Upload a profile picture") ...

Django: aggregate returns a wrong result after using annotate

Local time for report generation
I am working on a device that will be measuring certain data and creating pdf's based on this data. The device is running a Windows IOT core front end and django on the back end on a separate device. The two communicate using an api from the django server. The problem that I am currently generating the reports on the backend and sending them to the front end, and when i am taking the date when the data is collected to create the report it is always in UTC, which is expected. We need to be able to generate these reports in the users current timezone. The user can set the timezone of Windows IOT through a built in endpoint on the administration portal. The problem for the back end is that it is only accessible from the IOT interface so we need some way to set the timezone using the set timezone on the front end or at least pass the timezone to the function that is creating the report so we can convert the UTC datetime stamp to whatever the user has set. The big problem is that what is available for the Windows IOT is there are … -

How can I use signed urls in my template with DRF?
I'm using vue as a frontend framework. Users are able to CRUD images. The images are restricted to a group of users. Therefore security of the images is required.
