How to convert string to uniqueidentifier in Django?
I'm trying to insert a pre-generated GUID to MS SQL database from another MS SQL database via Django ORM, but keep getting Conversion failed when converting from a character string to uniqueidentifier. I've already changed my field in model to UUID field and started creating UUID object from my UUID character string, but still I get this mistake. What can I do to effectively insert this data to DB?

How can I encrypt/decrypt a text field on the fly with django
To simplify, I have a model called Entry with the following fields entry_date description I have a form created with both the fields mapped to it. I want to encrypt the description field while storing in a sqlite database, and decrypt it when retrieving it and displaying for the user interface. I read that I need to create a custom class and implement the encryption and decryption methods in that class. I created a custom class called EncryptedDescription, and added the get_prep_value and from_db_value that saves/retrieves the new field from the database. But should this new custom class (e.g. encrypted_description) be an additional field in my Entry model? Or should I replace the description field with the encrypted_description field? Additionally, how do I map this custom class to a django model form? When I try to add the encrypted_description it gives me an error "encrypted_description cannot be specified for model form as it is a non-editable field" I've browsed through so many examples but I'm still confused about the above two questions. Appreciate your guidance. -
nginx how to host both react and django
i have a react frontend imported inside a django backend. communication between the two is done through django-rest-framework. on the react's side, fetching is done through relative paths therefore in my package.json i have added the line: "proxy": "http://127.0.0.1:8000", django is hosting react-app locally without problems when i run: python3 manage.py runserver. on the remote i am trying to use nginx with gunicorn to deploy this app on aws ubuntu instance and run into the problem: first, i'm running python3 manage.py collectstatic later, i'm pointing nginx to that static_files for the index.html success! nginx serves react static files use gunicorn myapp.wsgi -b 127.0.0.1:8000 to run django problem! nginx served react files do not fetch anything. fetch does not call for this local path but instead calls public ip of aws instance. also, i cannot simulate get/post requests to the django backend because i think nginx "covers" django's gunicorn generated paths. please tell how can i connect nginx-served react frontedn to gunicorn run django my nginx sites-enabled/example server { listen 80 default_server; listen [::]:80 default_server; root /home/ubuntu/fandigger/frontend/build/; server_name public_ip_without_port; location / { try_files $uri $uri/ =404; } } -
ECONNREFUSED when fetching from localhost:3000 to localhost:8000 (Nextjs - DjangoApp)
When trying to make a 'POST' request using the 'fetch' node function, between the frontend and the backend (React Next.js and Django), I got an 'ECONNREFUSED' error. Backend requests using Postman worked as expected. Django is on port: 8000 and Next.js is on port: 3000. It was working until I installed the XCode, Ionic and Capacitor packages (I don't really know if they are the reason I'm getting this error).

Prevent Django to save an specific form from a formset
I'm working with a Django formset and I'm trying to prevent certain forms that could be partially filled to be saved. Form: class WeeksForm(forms.ModelForm): monday = forms.DecimalField(required=False) tuesday = forms.DecimalField(required=False) wednesday = forms.DecimalField(required=False) thursday = forms.DecimalField(required=False) friday = forms.DecimalField(required=False) saturday = forms.DecimalField(required=False) sunday = forms.DecimalField(required=False) class Meta: model = Weeks fields = ('activity', 'monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday', 'sunday') Formset: WeeksFormset = modelformset_factory(Weeks, form=WeeksForm, extra=10, can_delete=True) I'm dynamically generating the forms using JS and it automatically fills the field 'activity' but the problem is that sometimes the user might decide to not complete the other fields (those named with weekdays, "monday", "tuesday", etc...). If that is the case I end up with an "empty" form (not really empty because the field "activity" was filled) that I'm not interested in saving. I'm trying to somehow prevent in my view that these forms are saved: views.py if request.method == 'POST': formset = WeeksFormset(request.POST) if formset.is_valid(): for form in formset.forms: # From here is pseudocode, I want that if a form has all the weekdays empty that form is not saved if form.instance.monday and form.instance.tuesday and ... form.instance.sunday == None: form.delete() # End of pseudocode, this approach didn't work form.instance.user = request.user … -
django application code in @staticmethod or class?
I have long functions in my Django application like process staff pay, I dont want these functions directly in the view, so I moved them out to their own python files but the only way I could call the functions from the view was to make them @staticmethod, this seems wrong. How do I create a module and then call the functions without making the functions static? -
Django - constraint that uses related field value
As of now, it isn't possible to create constraints that use joins so I'm trying to figure out how I can do this. I want to make sure (on a DB level) that ResponseDetail.object is NOT null if response__action=='added' and IS null if response__action=='removed'. I can't modify Response model. class Response(..): action = CharField # added/removed class ResponseDetail(..): response = OneToOneField.. object = OneToOneField... class Meta: constraints = [ # CheckConstraint( # check=Q( # Q(response__action="added", object__isnull=False) # | Q(response__action="removed", object__isnull=True) # ), # name="object_only_if_action_added", # ) ] The CheckConstraint would work if Postgres and Django supported joins in constraints. Another solution is to add ResponseDetail.response_action field but I'm curious if there is a solution that doesn't expect me to add such field. -
Django rest framework - using SerializerMethodField with ModelSerializer
I have the following models. models.py class Language(models.Model): name = models.CharField(max_length=255, unique=True) class Subject(models.Model): name = models.CharField(max_length=255, unique=True) class Term(models.Model): subject = models.ForeignKey(Subject, on_delete=models.CASCADE) language = models.ForeignKey(Language, on_delete=models.CASCADE) name = models.CharField(max_length=255) definition = models.TextField() image = models.ImageField(default='', blank=True) I want to write a Serializer that will return a list of subjects. Each subject has a term field, which contains None or a single object, depending on the condition. serializers.py class TermSerializer(serializers.ModelSerializer): language = serializers.CharField(source='language.name') def to_representation(self, data): data = data.get(language=self.context['language']) return super(TermSerializer, self).to_representation(data) class Meta: model = Term fields = ('id', 'language', 'name', 'definition', 'image') class FilteredSubjectSerializer(serializers.ListSerializer): def to_representation(self, data): if self.context['condition']: terms = Term.objects.filter(language=self.context['language']) data = data.filter(term__in=terms) return super(FilteredSubjectSerializer, self).to_representation(data) class SubjectSerializer(serializers.ModelSerializer): term = serializers.SerializerMethodField() def get_term(self, term): if self.context['condition']: return TermSerializer(many=False, source='term_set').data return None class Meta: model = Term list_serializer_class = FilteredSubjectSerializer fields = ('id', 'name', 'definition', 'image', 'term') The problem is that when condition == True, the ViewSet returns incorrect data. All fields inside term have a default value. It works fine if I write SubjectSerializer like this: class SubjectSerializer(serializers.ModelSerializer): term = serializers.TermSerializer(many=False, source='term_set') class Meta: model = Term list_serializer_class = FilteredSubjectSerializer fields = ('id', 'name', 'definition', 'image', 'term') But the case when condition == False doesn't … -

Django inlineformset_factory. Request.FILES not returning filename to form when formset.is_valid() = False
I'm trying to allow the user to upload images tied to a project. I'm doing this via an inlineformset_factory. Im serving the form to the user trough a function based view. When the user fails to fill in one (or more) of the formsets correctly formset.is_valid() returns false and the bound formsets get returned to the user along with error messages. What i'm having trouble with is that the imagefield is not returned to the bound form. So if the user has filled in 2 out of 3 forms correctly then neither of the formsets have a bound imagefield after the failed validation. I can't manage to figure out if this is working as intended or if i'm doing something wrong. If i print out request.FILES i get the following: <MultiValueDict: {'image_set-0-filename': [<InMemoryUploadedFile: IMG_0017.jpg (image/jpeg)>], 'image_set-1-filename': [<InMemoryUploadedFile: sprite.svg (image/svg+xml)>]}> I would like the imagefield to be bound and show the user what value the field has. before incorrect form submission after incorrect form submission Hopefully you can see where my mistake is or tell me if i'm thinking about this the wrong way.

Django - Optimize grouping

Updating data without redirecting to an update template
I'm learning django and trying to make a to-do app. I want to be able to change the status of a task from 'active' to 'finish' without redirecting the user to a different page just to update the status of a task. i've been reading the docs for the UpdateView class to see if there was a method that allow me to update the value of the status directly but couldn't find anything. -
Custom User Manager is not working in django
I have problem with custom user manager. It's not working properly, i mean it was working well but it stopped for some reason that i don't know (maybe i broke something). I can create user through my register page, but if i delete whole UserManager class nothing changes. It doesnt raise errors even if it should, normalize class for email is not working etc. What's more when i create superuser via "python manage.py createsuperuser" command everything is working fine. Models.py class CustomUserManager(BaseUserManager): def _create_user(self, email, user_name, password, first_name, last_name, **extra_fields): if not email: raise ValueError("Email must be provided") if not password: raise ValueError("Password is not provided") user = self.model( email=self.normalize_email(email), user_name = user_name, first_name = first_name, last_name = last_name, **extra_fields ) user.set_password(password) user.save(using=self._db) return user def create_user(self, email, user_name, password, first_name, last_name, **extra_fields): extra_fields.setdefault('is_staff', True) extra_fields.setdefault('is_active', True) extra_fields.setdefault('is_superuser', False) return self._create_user(email, user_name, password, first_name, last_name, **extra_fields) def create_superuser(self, email, user_name, password, first_name, last_name, **extra_fields): extra_fields.setdefault('is_staff', True) extra_fields.setdefault('is_active', True) extra_fields.setdefault('is_superuser', True) return self._create_user(email, user_name, password, first_name, last_name, **extra_fields) class MyUser(AbstractBaseUser, PermissionsMixin): email = models.EmailField(db_index=True, unique=True, max_length=254) user_name = models.CharField(max_length=50, unique=True) first_name = models.CharField(max_length=240) last_name = models.CharField(max_length=240) friends = models.ManyToManyField('self', blank=True) date_joined = models.DateTimeField(auto_now_add=True) is_staff = models.BooleanField(default=True) is_active = models.BooleanField(default=True) is_superuser = … -
I have a problem with MySQL and Django on Docker: "sql_mode=only_full_group_by"
"Expression #3 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'database_name.i.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by" Hi, sorry for me English. I have a problem with MySQL and Django when I dockerize my project. I'm new with this technologies.

Expecting to get "non_field_errors: Unable to log in with provided credentials", but not getting it
Expectation: when wrong login credentials are provided, "non_field_errors: Unable to log in with provided credentials" is returned, such as below (screenshot from a tutorial which I'm following verbatim) Reality: instead I'm getting the error below. This gets printed to the console: POST http://127.0.0.1:8000/api/v1/token/login 400 (Bad Request) Interestingly I get this same error when I try to create users with passwords that are too short. I'm not having any issues with axios or the server when I provide the right credentials for log in, or use passwords of sufficient length when creating new users. When trying to catch errors such as these that I'm failing to get the expected result. My code for catching the error is the same as in the tutorial: methods: { submitForm() { axios.defaults.headers.common['Authorization'] = '' localStorage.removeItem('token') const formData = { username: this.username, password: this.password } axios .post('/api/v1/token/login', formData) .then(response => { const token = response.data.auth_token this.$store.commit('setToken', token) axios.defaults.headers.common['Authorization'] = 'Token ' + token localStorage.setItem('token', token) this.$router.push('/dashboard/my-account') }) .catch(error => { if (error.response) { for (const property in error.response) { this.errors.push(`${property}: ${error.response.data[property]}`) } } else if (error.message) { this.errors.push('Something went wrong. Please try again!') } }) } } Is there something in the server settings that I … -
Is there a way to use django url template in json_script?
trying to find a way to save a url into a json script but its not rendering and reading it literally unlike other values: Tried this way {{ "{% url 'tutorhomepage:tutorSelectedDay' tutor_id selected_date%}" | json_script:"url_test"}} And this way: {{ url_test | json_script:"{% url 'tutorhomepage:tutorSelectedDay' tutor_id selected_date%}"}} But still comes out like this: <script id="url_test" type="application/json">"{% url 'tutorhomepage:tutorSelectedDay' tutor_id selected_date%}"</script>
