How can I make one user can give only one rating to an item?
How can I make one user can give only one rating to an item? I read about UniqueConstraint but I can't understand how to use it here. models.py #...

Django app with Heroku with a virtual display
I have an app that uses Python Turtle to draw images. I use tkinter to create a window and PIL to do an ImageGrab to save a PNG. How do I run this on Heroku where I cannot directly access the server and specify a virtual display? I can make this work with Xvfb on my own server, but I don't know how to use Xvfb with Heroku. Everything I can find online about this is from 2015, so I highly doubt the solutions presented there are still relevant. -

Django Trying to render the data that i added to a DetailView via get_context_data()
I'm making a simple real estate app where users can create Estates. The Estate model has one main image, but the user can upload multyple images using another model and form for that. On the estate details page which is a DetailView I want to display the images and info about the user who is the owner of the current Estate. I'm passing the above info using get_context_data(). While debugging everything seems fine to me the context contains the info about the user and the images but this information is not rendered. Can you please help me with this issue? my user model is linked to the current estate with the following: class Estate(models.Model): user = models.ForeignKey( UserModel, on_delete=models.CASCADE, ) This is the EstateImagesModel class EstateImages(models.Model): IMAGE_UPLOAD_TO_DIR = 'estates/' estate = models.ForeignKey( Estate, related_name='images', on_delete=models.CASCADE, ) image = models.FileField( upload_to=IMAGE_UPLOAD_TO_DIR, ) and the detail view is class EstateDetailsView(views.DetailView): model = Estate template_name = 'main/estates/estate_details.html' context_object_name = 'estate' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['is_owner'] = self.object.user == self.request.user estate_images = list(EstateImages.objects.filter(estate_id=self.object.id)) seller = Profile.objects.filter(user_id=self.object.user_id) context.update({ 'estate_images': estate_images, 'seller': seller, }) return context -
How to make a value unique for 2 fields in Django model?

Django CKEditor Code Snippet not rendered correctly
I am building a Django blog that supports code snippets for both post and comments. The following is my CKEditor config in settings.py CKEDITOR_CONFIGS = { 'default': { 'toolbar': 'full', 'extraPlugins': ','.join( [ 'codesnippet', 'widget', 'dialog', ]), }, 'comment': { 'toolbar_Full': [ ['Styles', 'Format', 'Bold', 'Italic', 'Underline', 'Strike', 'SpellChecker', 'Undo', 'Redo'], ['Link', 'Unlink', 'Anchor'], ['Image', 'Flash', 'Table', 'HorizontalRule'], ['TextColor', 'BGColor'], ['Smiley', 'SpecialChar'], ['Source'], ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'], ['NumberedList','BulletedList'], ['Indent','Outdent'], ['Maximize'], ['CodeSnippet'] ], 'extraPlugins': ','.join( [ 'codesnippet', 'widget', 'dialog', ]), } } All instances of RichTextField in the models and forms are replaced with RichTextUploadingField. Then I ran the migrations. My text field has the code snippet button. Clicking the button allows the end users to post code snippets. But when the form is submitted the snippet is not marked down correctly. There are no markdown nor syntax highlighting. Am I missing something within the configs? Or does Django's form have limited support for code snippets? -

Django testing - group object not working when using factory_boy
I'm trying to streamline my testing by using factory_boy. I would like to test views that depend on some group permissions. If I write my test by creating a user and group in setUpTestData, I can get the test to work. However, if I create the user and group using factory_boy, it doesn't look like the permissions are set in the test. view @method_decorator([login_required, teacher_required], name='dispatch') class GradeBookSetupCreateView(PermissionRequiredMixin, UpdateView): raise_exceptions = True permission_required = 'gradebook.change_gradebooksetup' permission_denied_message = "You don't have access to this." form_class = GradeBookSetupForm model = GradeBookSetup success_url = "/gradebook/" def get_object(self, queryset=None): try: obj = GradeBookSetup.objects.get(user=self.request.user) return obj except: pass The permission problem is from the PermissionRequiredMixin and permission_required. There is also a permission in the decorator but that is working fine.

Rebase git branch upon 2 pull requests
I have a Django project with 4 other members, and I'm creating a model, let's call it "model M". Model M is having 2 foreign keys, the first is model A and the other is model B. At this moment, model A and model B are both not approved and merged to the main branch on our GitHub repo, and both on different pull requests, and I need to rebase my current branch of creating model M upon those 2 pull requests of A and B. I know I can rebase my branch on 1 pull request, but is it possible to rebase it upon 2 different pull requests? If so, how can I do it without having them rebase on each other (because they don't really rely on each other)? Thanks! I've rebased my branch on the first pull request, model A. But when I've tried to rebase the current branch on model B as well, I got conflicted (because they don't have the same commit history). -
After an upload, why is the image field put as null and also get a multipart form error? Is there a way to wrap formData in post_create in auth.js?

Django - Performance checking permission in template
I have a template that is a header snippet that is used on every page of the platform. What I would like to know is what performance implications/issues checking permission with {% if perms.foo.add_bar %} can have on the platform. And if there is a better way to do this. I checked the load/request time of the page on Django Toolbar and didn't seem to change at all. Although I tested just at my local environment, not the production (don't have access). -

Can I create django-like auth app using FastAPI?
As I understand FastAPI is good for building APIs. However I was wondering, will I be able to create a Django-like web-app, say e-commerce app with accounts and cart, using FastAPI. I glanced at docs and couldn't find any kind of auth features, login/logout/signup, Forms validating that input etc. Is that available from the box or there are some libraries? Does it even make sense or it is better to use Django/flask? -

How to make a model not available on sertain dates and hours in Django?
So, I'm creating a room renting project. The renting is not for a whole day, it's only for 2 hours. I'm gonna have several renting companies each having several rooms for rent with diffrent capacity. So, my question is, if a room is rented on lets say 25/03/2022 20:00(so its gonna be unvailable until 22:00, and also unavailable 2 hours prior), I want the room to be still visible on the site, because someone maybe will want to rent it on diffrent day or the same day in diffrent hour. How to make this exact room unavailable only on this date and this hours? If I make is_available row in the model its gonna switch to False whenever someone rent it, but I want it to be available for all the other days and hours. Here are the models: class Owner(models.Model): name = models.CharField(max_length=100) address = models.TextField() phone = models.PositiveIntegerField() class Room(models.Model): number = models.CharField(max_length=100) owner = models.ForeignKey(Owner, on_delete=models.CASCADE) capacity = models.PositiveIntegerField() is_available = models.BooleanField(default=True) class reservation(models.Model): room_number = models.ForeignKey(Room) guest_name = models.CharField(max_length=200) guests = models.PositiveIntegerField() date_reserved = models.DateTimeField() -
