ValidationError: is not a valid UUID in Django
I'm using Django 2.0 I have a Note table and StarredNotes table. Initially, there was no id field as it was added by default by Django as integer data type. Now I have changed the data type of id to UUID in model model.py class Starred(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) user = models.ForeignKey(User, on_delete=models.CASCADE) note = models.ForeignKey(Note, on_delete=models.CASCADE) objects = StarredManager() and views.py class StarredNotes(ListView): template_name = 'notes/starred.html' model = Starred context_object_name = 'starred_notes' def get_queryset(self): starred_notes = Starred.objects.filter(user=self.request.user).order_by('-updated') return starred_notes @method_decorator(login_required) def dispatch(self, request, *args, **kwargs): return super(self.__class__, self).dispatch(request, *args, **kwargs) and urls.py app_name = 'notes' urlpatterns = [ path('starred-notes/$', StarredNotes.as_view(), name='starred'), ] but when I access the view using http://127.0.0.1:1234/notes/shared-notes/ It gives error as ValidationError at /notes/shared-notes/ ["'shared-notes' is not a valid UUID."] -
How to handle video files uploads with django
I'm working on a django project that requires video files of any kind to be uploaded and then transcoded. Everything work fine its just that I sporadically get a "Timeout when reading response headers from daemon process" when uploading a video (well under 2GB in size). This occurs before any processing of the file. I've looked online for a solution and have tried several things to fix, including WSGIApplicationGroup %{GLOBAL} in the httpd.conf and increasing the TimeOut values, but the problem persists. Is there anything I can do in python/django to fix this issue? -

'AttributeError' when overriding 'RelatedField' in Serializing
I'm working with a Django project that implement the Rest framework. I have this model class Portfolio(models.Model): ticker = models.CharField(max_length=10, default='???') name = models.CharField(max_length=25) amount = models.FloatField() owner = models.ForeignKey('auth.User', related_name='portfolio', on_delete=models.CASCADE) def __str__(self): return self.name Note on the 'owner' ForeignKey. And in my serializers.py I have this class MyRelatedField(serializers.RelatedField): def to_representation(self, obj): return 'Test' class UserSerializer(serializers.ModelSerializer): portfolio = serializers.MyRelatedField(many=True) class Meta: model = User fields = ('url', 'id', 'username', 'portfolio') AS I read on the docs, I should override the RelatedField (which I did) if I want a custom representation. However when I try to run I get this error AttributeError: module 'rest_framework.serializers' has no attribute 'MyRelatedField' No matter what I return in MyRelatedField, the same error occurs. My question is how to debug and ideally, fix this error. Thank you. -

Can't use django variable in include tag
I'm trying to include a .html using {% include "paintings/experiments/points/{{substance.name}}.html" %} This however leads to the error TemplateDoesNotExist. If I hardcode the name of the .html file, it does work. {% include "paintings/experiments/points/fabric.html" %} And, in fact, I can use {{substance.name}} inside the included html, were it does indeed get substituted for fabric. Why can I not use a django variable when using an include tag? -
Django: Hide language prefix conditionally
I'm trying to hide the language prefix in my URL depending on a configuration saved in the database. I already know that setting prefix_default_language=False will hide the default language. My problem: I need the default language to be hidden or showed dynamically depending on a saved object in the database. My idea: create a middleware that reads the object in database and show or hide the prefix. Additional info: I am using the middleware 'django.middleware.locale.LocaleMiddleware'. -
Cutom widget in Django template using inline_formset
I have 2 models Company and CompanyLogo, where CompanyLogo has an FK to Company. For the CompanyLogo I want to have a custom widget. Even if I created a custom widget Django is still using the default Widget, and I don't know why ? The relation between CompanyLogo and Company is 1 to many. It is the same logo, but on different size. If I want to show only a specific size of the logo in widget, how can I replace the for loop and pass that specific size in template ? Models: class Company(Meta): name = models.CharField(max_length=255) class CompanyLogo(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) logo = models.ImageField(upload_to='static/temp') Forms: class CompanyLogoModelForm(forms.ModelForm): class Meta: model = CompanyLogo fields = ['logo'] widgets = { 'logo': forms.CompanyLogoWidget } CompanyLogoFormSet = forms.inlineformset_factory(parent_model=Company, model=CompanyLogo, form=CompanyLogoModelForm, extra=1, can_delete=True) Template: {% for logo_form in form.logos %} {{ logo_form }} {% endfor %} -
Is it possible to pass values from a query to models.py in django?
I'm trying to make an app that some person inserts an id and a birthday date from someone and outputs something. My doubt here is: having a query (from oracle) with the severall id and birthday dates using: connection = cx_Oracle.connect(...) cursor = connection.cursor() cursor.execute("query") My question is: Is it possible to pass some values from the query to my models.py file? For example, in my "models.py" file I have a field called "id" and I would like to pass all the records from the query in the field "doente" to the "models.py" file as "id". My form is something like this: Form where the values from the fields: "GTS do autorizante" and "Data de nascimento do autorizante" are in my models.py and the values from the fields: "GTS do autorizado" and "Data de nascimento do autorizado" come from the query. I would like to copy all the values from the query to my models.py file but I don't know if that is possible. -

struggling with Django Chosen Form
I'm a new developer and I've come across a javascript library called Chosen.js which would work wonderful for my schools senior project. My problem is I'm having issues getting started and getting the chosen form to show up using django-chosen. I believe it's related to the invalid line break showing up in the linting tool and i'm missing something else. After the pip install django-chosen I've added chosen to my installed files in settings.py as shown below: INSTALLED_APPS = [ 'django_python3_ldap', 'chosen', 'django_extensions', 'django_filters', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'accounts', ] Then I created my chosen form: from django import forms from .models import User, FacilityDimension from django.forms import ModelForm from widgets import ChosenSelectMultiple from chosen import forms as chosenforms class ChosenModelForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(ChosenModelForm, self).__init__(*args, **kwargs) for field in self.fields: if self.fields[field].__class__.__name__ in ['ChoiceField', 'TypedChoiceField', 'MultipleChoiceField']: choices = self.fields[field].choices self.fields[field] = chosenforms.ChosenChoiceField(choices=choices) elif self.fields[field].__class__.__name__ in ['ModelChoiceField', 'ModelMultipleChoiceField']: queryset = self.fields[field].queryset self.fields[field] = chosenforms.ChosenModelChoiceField(queryset=queryset) class FormFacilityDimension(ChosenModelForm): class Meta: model = FacilityDimension After my form is created I use the following in my template, I receive no errors, but i'm not able to get it to show up: {% block extra_js %} {{ block.super }} {{ form.media }} … -

django translation logged in user doesn't work
I am struggling with this for days now. My translations work when the user is logged out (django finds all the translations files, also when I use a switch) But once the user is authenticated, django changes the selected language with the default one. django could not find the translation files, only the default language works. Even if I use a switch, the selected language is replace by the default. I work with django allauth. I can't explain this issue. Who could help? Thank you so much for the great help -

Django reverse url not matching despite finding the right url [duplicate]
This question is an exact duplicate of: NoReverseMatch with keyword argument uidb64 with Django 2.0 1 answer I have the following in the main url.py file url(r'^authentication/', include(authentication.urls.urlpatterns)), and the following line in the auth url.py url(r'confirm/(?P<uidb64>[0-9A-Za-z]+)-(?P<token>.+)/$', confirm_email_with_token, name="confirm_email"), and when I try to render the reverse url like so {% url 'confirm_email' uidb64=uid token=token %} I get the following django.urls.exceptions.NoReverseMatch: Reverse for 'confirm' with keyword arguments '{'uidb64': b'MTU', 'token': '4sk-9bb9de4589dcfd386fdc'}' not found. 1 pattern(s) tried: ['authentication/confirm/(?P<uidb64>[0-9A-Za-z]+)-(?P<token>.+)/$'] Reverse lookup for the passwordresetview also defined in the authentication urls is working fine.

Add OneToMany relation model instances from parent model instance Django Form
I have a Person model: class Person(models.Model): name = models.CharField(max_length=100) And then a Car model: class Car(models.Model): plate = models.CharField(max_lenght=100) owner = models.ForeignKey(Person) And then a certain CarAttribute model: class CarAttribute(models.Model): whatever = models.CharField(max_lenght=100) car = models.ForeignKey(Car) Person has a relation 1 to many to Car. Car has a relation 1 to many to Car attributre. Is there a way in Django for adding the Car (and eventually its relative CarAttributes) in the Form to be used when adding a new Person? One person may have more than one car, and one car can multiple attributes. Any hints on how to approach this solution with Django? Or complementary tool? -

Why do we need Signatures in Celery?
I've started using Celery 4.1 in my Django Python project and have come across Signatures. In the documentation it says the following: You just learned how to call a task using the tasks delay method in the calling guide, and this is often all you need, but sometimes you may want to pass the signature of a task invocation to another process or as an argument to another function. A signature() wraps the arguments, keyword arguments, and execution options of a single task invocation in a way such that it can be passed to functions or even serialized and sent across the wire. Although I see them used in some of the examples I don't really know when and why to use them, as well as which problems they solve. Can someone explain this to a layman? -
