Django ForeignKey Works for Filter but not List Display
I am trying to list a ForeignKey value in Admin list_display. I am trying the solution below which seems to be the solution everyone uses, but I just get an error 'NoneType' object has no attribute 'first_name' Have I listed this correctly? Thank you. Plaque Model class Plaque(models.Model): created_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='plaques', default=1) group = models.ForeignKey(Group, blank=True, null=True, verbose_name='Group Name') veteran = models.ForeignKey(Veteran, blank=True, null=True) ...

Cannot start apache after editing the config httpd file for wsgi
I'm trying to deploy my homepage. I used pip install mod_wsgi to get the wsgi. And what I understood is that I only have to change the httpd file with the following: WSGIScriptAlias / /home/rasmus/MainSite/src/MainSite/wsgi.py WSGIPythonPath /home/rasmus/MainSite/src/MainSite <Directory /home/rasmus/MainSite/src/MainSite> <Files wsgi.py> Order deny,allow Allow from all </Files> </Directory> I copied the directory below and pasted it into Users/rasmus/ - And I read somewhere that the home directory was found by %USERPROFILE%which opens Users directory When I try to start my apache server from services.msc I get the following error message: It runs if I remove it. So the apache server should be working, and I guess it's my configuration for deployment in httpd config that that is wrong. I use apache 2.4.25, Python 3.5.1 64-bit -
How do i update list in ListModelMixin?
I am using django rest framework to build out the backend.

Try to join a OneToOne relationship in Django
I need some help doing a join using Django, which seems like it should be easy. I have looked at the documentation but it seems like it won't join for some reason. I am trying to get in my view, the model.Photo and model.PhotoExtended with both joined and then displayed in the view. Currently I am just trying to get the model.Photo displayed but with a join which finds the request.user and filters it based on that. They are in different apps. models.py for model.Photo class Photo(ImageModel): title = models.CharField(_('title'), max_length=60, unique=True) slug = models.SlugField(_('slug'), unique=True, help_text=_('A "slug" is a unique URL-friendly title for an object.')) models.py for model.PhotoExtended class PhotoExtended(models.Model): Photo = models.OneToOneField(Photo, related_name='extended', help_text='Photo required', null=True) user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, help_text='User that uploaded the photo') views.py class PhotoExtendedUserView(ListView): template_name = 'photo_user_list.html' def get_queryset(self): user = get_object_or_404(User, username=self.request.user) return Photo.objects.filter(photoextended__user=user) -
How to exchange data between apps in Django using the database?
I'm using Django to work on a web. I have created 2 apps: One for the clients to register, and add their data to the database, and a second app for users to access and see the interactive interface. The idea is to use the second app to get data from the clients in the database, and use it to show some information to the user. My problem is that i don't understand how to make the second app to get the information from the database. Do i need to create the same models from the first app on model.py on the second one? Or how do i make the second app to use a Queryset to retrieve data from the database? -

convert query obj data to datetime obj
writing a management command that deletes records more than two weeks old. each model instance has a ‘confirmed_placed’ which I’m using as the comparison date. (‘confirm_placed’ is a CharField because it’s generated dynamically in a predetermined format). If my Item model looks like: class HotItem(models.Model): item_no = models.CharField(max_length=30, unique=True, blank=False, null=False) ad_date = models.CharField(max_length=20, unique=False, blank=True, null=True, default=None) create_date = models.DateField(default=date.today) item_name = models.CharField(max_length=210, blank=True, null=True) comments = models.TextField(max_length=2000, blank=True, null=True) reply = models.TextField(max_length=2000, blank=True, null=True) confirmed_placed = models.CharField(max_length=200, blank=True, null=True, default=None) def __str__(self): return u'%s %s %s %s %s' % (self.create_date, self.item_no, self.item_name, self.confirmed_placed, self.comments) What I need is the proper way to convert my objects confirmed_placed value to a date time obj and compare against twoweeksago (as defined below.) Something like: from .models import HotItem as Item twoweeksago = datetime.datetime.now() - datetime.timedelta(weeks=2) class Command(BaseCommand): help = 'Delete hotlist items placed more than two weeks ago' def handle(self, *args, **options): **hotrecords = Item.objects.filter(datetime.datetime.strptime(confirmed_placed.replace('.','').replace(',',''),' %b %d %Y')__gt=twoweeksago)** for record in hotrecords: record.delete() self.stdout.write(self.style.SUCCESS('Successfully deleted record old records')) any ideas on the proper way to format the query? -
How to configure nginx to serve static from django running in a docker container
Nginx is currently serving my site but missing all static content. I need to figure out what I'm doing wrong with this setup. docker-compose.py parentserver: build: ./parentserver expose: - "8000" links: - postgres:postgres - authserver:authserver volumes: - /usr/src/app - /usr/src/app/static env_file: .env environment: DEBUG: 'true' command: ./startup.sh nginx: build: ./nginx/ ports: - "80:80" volumes: - /www/static volumes_from: - parentserver links: - parentserver:parentserver Django settings.py STATIC_ROOT = os.path.join(PACKAGE_ROOT, "static1") STATIC_URL = "/static/" STATICFILES_DIRS = [ os.path.join(PACKAGE_ROOT, "static"), ] STATICFILES_FINDERS = [ "django.contrib.staticfiles.finders.FileSystemFinder", "django.contrib.staticfiles.finders.AppDirectoriesFinder", ] Not sure if relevant but if I docker exec into the parentcontainer running the Django app, my static directory is located at /root/proj/proj/static.

Delete FullCalendar Event Permanently
I have been stuck on this for a couple days now. I want to delete the events from the database. My model for storing the events: class Events(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL) name = models.CharField(max_length=32) start = models.CharField(max_length=32) end = models.CharField(max_length=32) description = models.TextField(blank=True) attendees = models.TextField(null=True) Of course, django automatically provides a primary key as well. So the user can add events by filling out a modal form which will trigger some ajax. $.ajax({ type:'POST', url:'createEvent/', data:{ name: name, myCheckboxes: myCheckboxes, // Simply contains the attendees start: start, end: end, description: description, csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val() }, sucess: function(data){ callback(data) } }); Then in my views.py: def createEvent(request): if request.method == "POST": members = request.POST.getlist('myCheckboxes[]') name = request.POST['name'] start = request.POST['start'] end = request.POST['end'] description = request.POST['description'] Events.objects.create( user_id=request.user.id, name=name, start=start, end=end, description=description, attendees=json.dumps(members) ) return HttpResponse('<p>Done</p>') I store the information into the database and here is how I render the event: var event={ allday:true, title: name, start: start, end:end, description: description}; event = $('#calendar').fullCalendar( 'renderEvent', event, false); And I get all these values from the modal form. Alright now heres the issue, when I try to delete the event, I need some way of extracting the correct event from the database. So … -

Django in an API like + reactjs. How to generate a csrf token
I did something a bit silly while developing my project: I'm using django only for the admin and the views are use as urls for my front (reactjs) for get actions. I've nothing to protect about the data itself. But the problem is that at some point I've got assets to download and this is the only time when I've to do a POST request to my django. And here is the problem. Django is waiting for a csrf token and I didn't succeed on ignoring that (I'm using base-class views). The really silly thing is that it was working until now as I was working with the django admin (which means django template -> csrf token generation). So for a standard user he won't have it... Do you have an idea how I could proceed? Should I pass by a fake django view to be sure that the user got it? (seems to be an ugly solution). Many thanks! -

Filtering users by scope using django-oauth-toolkit.
I'm brand new to using DRF and DOT, and have used the DRF quickstart to make a simple API, and have followed through using the DOT quickstart to use tokens to authenticate users. I am trying to extend this API so that there are two different types of users, each of which are given a scope that gives them access to certain data from the database. So my model looks like this: class Car(models.Model): title = models.CharField(max_length=50) stock = models.IntegerField() price_tier_1 = models.FloatField() price_tier_2 = models.FloatField() def __unicode__(self): return self.title If a user has scope "type_1", I want to be able to give him data which includes the "price_tier_1" field, but not the "price_tier_2" data, and visa versa, so have two serializers to do this, class TierOneCarSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Car fields = ('title', 'price_tier_1', 'stock',) class TierTwoCarSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Car fields = ('title', 'price_tier_2', 'stock',) In my view, I want to get what the user's token's authentication scope is, so that I can use the correct serializer to send them their data. I'm not sure if I'm doing this the way one is supposed to, and any help is greatly appreciated! -

django values function strange behaviors?
I have +5 hours training to explain how : Item.objects.values('type', 'state') returns a dictionary that contains only two keys. However Item.objects.values('type', 'state').annotate(nb=Count('id')) works !! How does the interpreter knows that id attribute exists if it's not returned by values function ?
