Got AttributeError when attempting to get a value for field `username` on serializer `UserSerializer`
I'm trying to extend the django.contrib.auth.models.User model. Currently, the model that is referenced in the exception looks like this: from django.db import models from django.contrib.auth.models import User class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) dob = models.DateField() def __str__(self): return self.user.username And my serializer class looks like this: from rest_framework import serializers from django.contrib.auth.models import User class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('username', 'email') I don't see where the serializer is getting UserProfile or why this exception is happening: AttributeError: Got AttributeError when attempting to get a value for field `username` on serializer `UserSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `UserProfile` instance. Original exception text was: 'UserProfile' object has no attribute 'username'. -
How to capture output from Python smtp debug server
I'm trying to write unittests for some custom Django email backends, and to test it against a "real" smtp server, I'm trying to use Python's built-in smtpd debugging server by running: python -m smtpd -n -c DebuggingServer localhost:1025 My unittest basically looks like: class Tests(TestCase): @override_settings(EMAIL_BACKEND='mycustombackend') @override_settings(EMAIL_HOST='localhost') @override_settings(EMAIL_PORT='1025') def test_backend(self): from django.core import mail mail.send_mail( subject='Subject here', message='Here is the message.', from_email='from@example.com', recipient_list=['to@example.com'], fail_silently=False, ) and when I run this, the smtpd process outputs the email content correctly. However, when I try and capture that so I can confirm it in my unittest, I get nothing. I've tried using the subprocess package, to launch the process and read the output via pipes, but it never receives any output. I thought I was using subprocess incorrectly, so as a last resort, I tried launching the process with: python -m smtpd -n -c DebuggingServer localhost:1025 > /tmp/smtpd.log and reading the log file. However, even with that, no output is ever written to the file. What's going on here? -
Updating an ManyToMany field with Django rest
I'm trying to set up this API so I can use a "PUT" to update one/many "TAG"s on an item in the model "MOVIE". Tags is an M2M on MOVIE. I am posting on the PK of the item in movie.

how do I set up a image upload to a folder that the folder name is a value of another field in the model in DJango
I have a model with some fields: class RankStructure(models.Model): RankID = models.CharField(max_length=4) SName = models.CharField(max_length=5) Name = models.CharField(max_length=125) LongName = models.CharField(max_length=512) GENRE_CHOICES = ( ('TOS', 'TOS'), ('TMP', 'TMP'), ('TNG', 'TNG'), ('DS9', 'DS9'), ('VOY', 'VOY'), ('KTM', 'KTM') ) Genre = models.CharField(max_length=3, choices=GENRE_CHOICES) image = models.FileField(upload_to='RANKS/'+<<GENRE>>+'/', blank=True) In the last line is an image FileField.

How to implement multiple inlines in a FormView like in django admin
I´m newbie with django, I'm trying to replicate the inlines in the Django admin for adding related models to my Foto Model, it has three foreign keys to different models, I found this code http://kevindias.com/writing/django-class-based-views-multiple-inline-formsets/ but it is something different of what i want, because the foreign keys, in my case, are relations from Foto to other three models. I want to create a Form with all the fields from associated models. My models.py is: class Foto(models.Model): fotoID = models.AutoField(primary_key=True) imgfile = models.ImageField(upload_to='fotos/',null=True, blank=True) camara = models.ForeignKey(Camara, null=True) punto_muestreo = models.ForeignKey(PuntosMuestreo, null=True) colector = models.ForeignKey(Colectores, null=True) fecha = models.DateField(blank=True, null=True) def __str__(self): return str(self.filename) class Colectores(models.Model): colectorID = models.AutoField(primary_key=True) name = models.CharField(max_length=510, null=True) institution = models.CharField(max_length=510, null=True) e-mail= models.CharField(max_length=255, null=True) def __unicode__(self): return unicode(self.nombre) class PuntosMuestreo(models.Model): puntoID = models.AutoField(primary_key=True) nombre = models.CharField(max_length=255) latitud = models.FloatField(blank=True, null=True) longitud = models.FloatField(blank=True, null=True) datum = models.CharField(max_length=50, blank=True, null=True) elevacionMinima = models.IntegerField(null=True, blank=True) elevacionMaxima = models.IntegerField(null=True, blank=True) class Camara(models.Model): camaraID = models.AutoField(primary_key=True) modelo = models.CharField(max_length=510, null=True) cantidad_fotos = models.IntegerField(null=True, blank=True) archivo_inicial = models.CharField(max_length=255, null=True, blank=True) archivo_final = models.CharField(max_length=255, null=True, blank=True) In my views.py I only got an inline for PuntosMuestreo form but with inlineformset_factory can´t include Camara and Colectores inline forms, only get camara … -

Django ImportError No module named x.settings
I have the following structure: mysite -> manage.py -> mysite (again) -> __init__.py -> wsgi.py -> settings.py etc -> myapp -> __init__.py -> myscript.py -> models.py etc When I run a script from myapp (that does myapp-related things, putting stuff in a the database for example) i need to do import django django.setup() in order to be able to from models import MyModel.

What should I do to be able to place my scripts in myapp and still be able to use django.setup() from that dir? -
Deploying a Django app with Nginx + Uwsgi
So I am kinda new to uwsgi + nginx and I am trying build a docker container for a django app using nginx + uwsgi. The problem that I am experiencing is that I cannot get the nginx + uwsgi part to work. What I have in my uwsgi.ini file is: [uwsgi] wsgi-file = /path to/wsgi.py chdir = /new folder pythonpath = /var/www socket = :8000 And my conf file for nginx looks like this: server { listen 8000; server_name 192.168.99.100; #because of docker container charset utf-8; client_max_body_size 75M; location / { uwsgi_pass django; include /pathto/uwsgi_params; } } I saw I have to create a socket to link both of them, but every time I create a socket and replace :8000 in the uwsgi.ini file the container of the app simply exits. How am I actually supposed to tell uwsgi and nginx to work together? Furthermore, uwsgi seems to not load any apps, eventhough I read almost every single topic on the internet that I could find and did everything that was written... -
Removing null=True from Django model CharField are values updated to empty string
I have a error being thrown: coercing to Unicode: need string or buffer, NoneType found which I believe to be related to the null=True in many of my CharField's throughout my various models. I ran into this error when attempting to add Django Rest Framework Parsers to a ListAPIView like so: class TestList(generics.ListAPIView): """ """ def post(self, request, *args, **kwargs): return None queryset = Tests.objects.all() serializer_class = TestSerializer filter_class = TestFilter parser_classes = (FormParser, MultiPartParser) class Courses(models.Model): created = models.DateTimeField(default=timezone.now) name = models.CharField(max_length=200, unique=True) test = models.ForeignKey('Tests', blank=True, null=True, on_delete=models.CASCADE) class Tests(models.Model): name = models.CharField(max_length=200) it's either getting upset because of the null=True on the CharField's or perhaps because of the test foreign key I'm not totally sure? Would removing null=True and migrating solve this issue? Additionally, I should probably remove the null=True on CharField's anyway, would that be updated retroactively in the database? -
Django rest framework serialize ForeignKey field to list

The question is how to get a list of names related to a study from the Author table. Output should be: {"authors": ["author1", "author2", "author3"]} not {"authors": [1, 2, 3]} Here's what I tried: I added this line authors = serializers.SlugRelatedField(many=True, read_only=True, slug_field='author') to the StudySerializer class, but then I got a TypeError saying <Author: Author object> is not JSON serializable -

Django missing change history

How to dynamically change Django model without triggering migration?
I'm using a Django PyPI package, but I'm dynamically changing some of its model's help_text attributes by doing: from schedule.models import Event models.Event._meta.get_field('end_recurring_period').help_text = 'some better help text' to make the admin more user-friendly. However, after upgrading to Django 1.9, Django now bizarrely interprets this change as a schema change and refuses to migrate any other apps until I generate and run a migration to somehow "apply" this change to my database. Even worse, if I do generate the migration, it writes the migration into my virtualenv's dist-package directory, so it won't be captured by source control. How do I customize model help text without Django erroneously thinking I'm making schema changes? -

Non-model object in templates, why __call__() change the behavior?
Today I faced a strange issue on one of my development. I reproduced it with a very minimal example. Have a look at these 2 dummy classes (non Django model subclasses): class DummyClassA(object): def __init__(self, name): self.name = name def __repr__(self): return 'Dummy1 object called ' + self.name class DummyClassB(object): """Same as ClassA, with the __call__ method added""" def __init__(self, name): self.name = name def __repr__(self): return 'Dummy2 object called ' + self.name def __call__(self, *args, **kwargs): return "bar" They are identical, but the second have a special __call__() method. I want to display instances of these 2 objects in a view using the builtin Django template engine: class MyView(TemplateView): template_name = 'myapp/home.html' def get_context_data(self, **kwargs): ctx = super(MyView, self).get_context_data(**kwargs) list1 = [ DummyClassA(name="John"), DummyClassA(name="Jack"), ] list2 = [ DummyClassB(name="Albert"), DummyClassB(name="Elmer"), ] ctx.update({ 'list1': list1, 'list2': list2, }) return ctx and the corresponding template: <h1>Objects repr</h1> <ul> {% for element in list1 %} <li>{{ element }}</li> {% endfor %} </ul> <ul> {% for element in list2 %} <li>{{ element }}</li> {% endfor %} </ul> <h1>Access members</h1> <ul> {% for element in list1 %} <li>{{ element.name }}</li> {% endfor %} </ul> <ul> {% for element in list2 %} <li>{{ element.name }}</li> … -
