How can i compare two DateTimeFields with current time
Event has two DateTimeField's and i need to compare them to the actual date time in a same method. from django.utils import timezone event_starts = models.DateTimeField(_("Event starts")) registration_closes_at = models.DateTimeField( _("Registration ends:"), null=True, blank=True ) This is what i have tried, but it doesn't work. So what i need is: If event has been started or registration was closed user can not attend this event. def is_registration_open(self): now = timezone.now() passed_registration = now > self.registration_closes_at passed_start = now > self.event_starts if not passed_registration or not passed_start: return And tried this: def is_registration_open(self): if ( not timezone.now() > self.registration_closes_at or not timezone.now() > self.event_starts ): return Here is a fail: '>' not supported between instances of 'datetime.datetime' and 'NoneType' When i compare only event_starts everything is working fine.

Django two or more droplets sharing same sqlite database?
For one of my use-case I had to use a local sqlite database for one of my model. But as I am using load-balancing for my project, I cannot use two databases as all droplets would have different database. So, I was trying to find a way in which I can use a single local database in one of my droplet and then let other droplets read/write from this database. Is there any way to achieve this? -
Changing the size of bootstrap cards in a Django project?
I'm working on a simple Django project with bootstrap. I have a set of cards being displayed on a page, and the cards are showing just fine (Don't mind the place holder images). I've been reading the bootstrap docs about cards, but since I have less knowledge of CSS than I'd like, I can't figure out how to simply change the size of the cards so they are larger and stacked in rows instead of one column. This is my HTML template for this page. It just uses a for-loop to go through my projects and make a card for each. You can see I have the title and text worked out, and the URL to 'See Details'. {% extends "base.html" %} {% load static %} {% block page_content %} <h1>Projects</h1> <div class="row"> {% for project in projects %} <div class="col-md-4"> <div class="card mb-2"> <img class="card-img-top" src="{% static project.image %}"> <div class="card-body"> <h5 class="card-title">{{ project.title }}</h5> <p class="card-text">{{ project.description }}</p> <a href="{% url 'project_detail' project.pk %}" class="btn btn-primary"> See Details </a> </div> </div> </div> {% endfor %} </div> {% endblock %} The Base.html is just linking to the bootstrap and all the html for the top of the page.

Model UserProfile object has no attribute 'save'
So, I am trying to create an API user registration endpoint on my Django + DRF project. Whenever a user is registered it should create also a user profile. But, I am getting this error while printing sys.exc_info(): AttributeError("'UserProfile' object has no attribute 'save'") I am reading how to create objects in Django documentation says: from blog.models import Blog b = Blog(name='Beatles Blog', tagline='All the latest Beatles news.') b.save() So, I have tried that, I guess; this is where everything stops working: try: profile = UserProfile(user=user) if 'picture' in request.data: profile.picture = request.data['picture'] profile.save() except: print('USER PROFILE CREATION', sys.exc_info()) try: user.delete() except: print('USER DELETE ON PROFILE CREATION ERROR', sys.exc_info()) return Response(result, status=500) And this is my model definition: class UserProfile(models.Model): id = models.AutoField(primary_key=True) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) picture = models.ImageField( "Profile picture", upload_to='profiles/', blank=True ) created_at = models.DateTimeField("Created at", auto_now=False, auto_now_add=True) updated_at = models.DateTimeField("Updated at", auto_now=True) def __str__(self): return f'{self.user} user profile' class Meta: verbose_name = 'User Profile' verbose_name_plural = 'User Profiles' What am I doing wrong? -

Python how to download multiple files, zip them and return zip file
I need to download multiple images, write them into a zip archive and then have the client download said zip file. Currently this is the code that I have, the problem is that the zip files that are downloaded are always 67 bytes in length and are corrupted. def get(self, request): import requests from zipfile import ZipFile from io import BytesIO imgs = [ 'https://i.ytimg.com/vi/MPV2METPeJU/maxresdefault.jpg', 'https://www.cdc.gov/healthypets/images/pets/cute-dog-headshot.jpg', ] response = HttpResponse(content_type='application/zip') response['Content-Disposition'] = f'attachment; filename=Photos.zip;' mem_file = BytesIO() with ZipFile(mem_file, "w") as zip_file: for img in imgs: resp = requests.get(img) filename = img.split('/')[-1] zip_file.writestr(filename, resp.content) mem_file.seek(0) response.write(zip_file) return response I suppose I'm either using either the ZipFile or BytesIO incorrectly, any help is greatly appreciated. -
How to update every record in a model in django
I am trying to update every record in the model Lead whenever I update or create the model Holiday. Here is the signal in my models.py: # update all leads when holiday is newly created or edited def post_holiday_created_signal(sender, instance, created, **kwargs): Lead.objects.update() post_save.connect(post_holiday_created_signal, sender=Holiday) I need each of the records in the Lead model to update after Holiday has been edited or created. However, I am not sure if the above code works properly or not. I want the equivalent of going into each of the lead's update view and clicking the update button. I also want to mention that the lead-update view also has a def form_valid method, and I need that to work as well. Could you look at the code, and tell me if it works. If not, could you suggest some methods to do this? Thanks a lot. -

object after calling DestroyAPIView still exist
I have a web scraper with a no. of urls. I can manually subscribe or unsubscribe to the urls. Although, when I try to unsubscribe a list of urls, the log info says that they are deleted but I can still see them in the list of subscribed urls. Below is my code class SubscribeView(ListCreateAPIView): queryset = WebS.objects.all() serializer_class = WebSSerializer def post(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data, many=True) serializer.is_valid(raise_exception=True) instance = serializer.save() for i in instance: # do something return Response(serializer.data, status=status.HTTP_201_CREATED) class UnsubscribeView(DestroyAPIView): queryset = WebS.objects.all() serializer_class = WebSSerializer lookup_field = 'url' def post(self, request, *args, **kwargs): urls = request.data WebS.objects.filter(url__in=urls).delete() return Response(status=status.HTTP_204_NO_CONTENT) Note: I have used post in DestroyAPIView because by overriding delete or destroy I could not manually provide data in my API. The textbox was disabled, strangely. -

in ubuntu using the command "adduser (newusername)" cant login as that newly created user
I'm using Linode to deploy my django application. I'm using windows 10 using bash. After creating a new server I was able to log in as the root user just fine. when I try to create a new user using the command "adduser" NOT "useradd"(I saw a lot of issues involving useradd) Im using "adduser (newusername)" and it creates the user. then when I try to log in as that newly created user the bash tells me "permissions denied, please try again". I made sure I'm entering the correct password, even tried creating a couple different new users and changing the password the users I created but I get the same error. Does anyone know what I'm doing wrong??? -
TreeNodeChoiceField not iterable in a form - Django
I was wondering if someone was familiar with TreeNodeChoiceField from mptt in Django. I am trying to use this feature in a form to post an article on a blog.

Logging requests and responses sent from django heroku app
I'm wanting to capture all http requests made from my django app hosted on heroku. I'm wanting all of the information regarding the request that was made and the response of that request (including the body for both GETs and POSTs). I currently have sentry attached to my app and it looks like it captures all requests made when there is an error in the app (although it doesn't include the body). I'm wondering if there is an easy way to use sentry or some other heroku add on the capture all outgoing http traffic from my app. Or do I have to tap into the python logging module to achieve this? -
