Disable logging of `exc_info` when raising `BadRequest`?
When a Http404 is raised, the log provides the relevant information but not the details of the exception But when a BadRequest is raised, the log includes exc_info so it makes it look like something went wrong rather than standard error handling of bad requests. So is there a way to disable or modify this behavior? -

How to get csrfToken for front-end to submit logins in Django
I've read all the issues about this, but it's still not clear to me. I am not using Django templates to handle login functions (login, logout, changepassword, create user, etc). I tried POSTing to the accounts/login page with "username": <user>, "password": <password> But it also wants a CsrfViewMiddleware token. It's not clear to me where I get that. Does the front-end have to requrest it first from another endpoint? Is there some other way to do the CSR checking? -
CORS Policy Error with Specific Data in React and Django Application
CORS Policy Error with Specific Data in React and Django Application I'm experiencing an issue with CORS policy in my React frontend and Django backend application. The error message I'm receiving is: Access to fetch at backend URL' from origin 'frontend URL' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

custom storage-backend class not working as expected with s3, boto3 and django-storages
I am following this tutorial here from Michael Herman, trying to setup s3 storage for my django project and I am facing some issues right from the start of the tutorial. First, when I tried running the collectstatic command, I got this error: botocore.exceptions.ClientError: An error occurred (AccessDenied) when calling the PutObject operation: Access Denied I looked up a bit, and apparently you have to set AWS_DEFAULT_ACL = None and doing that fixed it. So now my static files were being uploaded to the s3 bucket when I ran collectstatic. But when I visited the webpages, the static images and stylesheets were not getting fetched as expected. I tried many different things at this point, but none of them worked. I typed the s3 object url in the browser and this was the error I was getting: <Error> <Code>AccessDenied</Code> <Message>Access Denied</Message> <RequestId>419CX01JK1CAKYCS<RequestId> <HostId>rB7y8qLl5a5G0I1LVx2lexUbJpcvnrdKIMZ3AVq69C81B3j4BRWZwLq5THNLINwSv6q5HFSAednN1yq2tRCQ6THuxEn+S/Kj</HostId> </Error> Now the next thing I did was to make all the bucket objects as public. The tutorial doesn't do this and I'm not sure if its a bad thing or not? Anyone please point out if it is. Using this answer, I set the Block all public access setting to off and also added a Bucket … -

Coloured output from native Django test runner
I'm trying to get a colored output (red or green) when running my Django tests with the native Django test runner. I'm running a poetry virtualenv (python 3.11.6) with Django (5.0.3) and colorama (0.4.6) in a zsh on MacOS but the output remains colourless. Following the Django documentation, I've set export DJANGO_COLORS="error=yellow/blue,blink;notice=magenta" in my zsh before calling python manage.py test apps.myapp. Yet, the output remains colourless. Same result when adding the --force-color option. However, spinning up the same virtualenv and executing from colorama import Fore, Style print(Fore.RED + 'This is red text' + Style.RESET_ALL) returns a red text (as expected). What do I have to do to get a colored output from the native Django test runner without switching to a different one? -

Case Insensitivity Issue with Tag Suggestions in Wagtail
I'm studying Wagtail and encountered the following issue when setting up tags. I added the following models: @register_snippet class BlogTag(TagBase): free_tagging = False name = models.CharField(max_length=25, unique=True) slug = models.SlugField(max_length=255, unique=True, blank=True) class Meta: verbose_name = "blog tag" verbose_name_plural = "blog tags" class TaggedBlog(ItemBase): tag = models.ForeignKey( BlogTag, related_name="tagged_blogs", on_delete=models.CASCADE ) content_object = ParentalKey( 'home.BlogPage', on_delete=models.CASCADE, related_name='tagged_items' ) I enabled the setting TAGGIT_CASE_INSENSITIVE = True. However, when a user fills in the tags while creating a page, the case is still taken into account - if the user enters a word in lowercase, options from the dropdown list do not appear. Here is the model, if it matters: class BlogPage(Page): tags = ClusterTaggableManager(through=TaggedBlog, blank=True) date = models.DateField("Мы это написали:") author = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True, related_name='blog_pages') body = StreamField([ ('heading', blocks.CharBlock(form_classname="title", label="Заголовок")), ('paragraph', blocks.RichTextBlock(label="Текст")), ('image', ImageChooserBlock(label="Изображение")), ('quote', blocks.BlockQuoteBlock(min_length='20', label="Цитата")), ('media', EmbedBlock(label="Ссылка на видео")), ], verbose_name='Содержимое') content_panels = Page.content_panels + [ FieldPanel('date'), FieldPanel('body'), FieldPanel('slug', permission='superuser'), FieldPanel('tags'), ] edit_handler = TabbedInterface([ ObjectList(content_panels, heading='Центр управления постами'), ObjectList(Page.promote_panels, heading='Promote', permission='superuser'), ]) def _get_unique_slug(self): slug = slugify(self.title) unique_slug = slug num = 1 while Page.objects.filter(slug=unique_slug).exists(): unique_slug = '{}-{}'.format(slug, num) num += 1 return unique_slug def save(self, *args, **kwargs): self.slug = self._get_unique_slug() super().save(*args, **kwargs) Please tell … -
Django is randomly ignoring certain days when I try to bulk_create. How do I solve this? How does this even happen?
How does Django randomly skip days when trying to bulk_create? The dataset is a CSV exported via a third party tool from a MSSQL Server. Exhibit 1 - Data from my database: Note the whole 2024-06-13 is missing. Exhibit 2 - Data dump from my dataframe: When I look at my pandas dataframe, there was data for 2024-06-13. So reading the CSV and parsing the date works. At first, I thought the issue was using too much memory to bulk_create so I tried chunking. The problem still remained. But if it was a memory problem, then it wouldn't so cleanly eliminate that day without affecting the other days around it. The session start/stop times correspond with when the shop opens and closes on the 12th and 14th. It's not the only day that randomly disappeared. There are other days before this as well that have vanished. Also, the last possible import date was 2024-06-24. After that, it won't import any more sessions that exists in my dataframe. I tried both SQLite and Postgres to no avail in case it was a database issue. This is how it's imported from my dataframe via DjangoORM: sessions = [Session(**row) for row in df.to_dict(orient='records')] … -
What is the correct way for implementing Hyphenopoly?
I'm having trouble implementing Hyphenopoly (https://github.com/mnater/Hyphenopoly) on a Django project. Sometimes it seems to work fine, sometimes not. Besides, on mobile browser the result are unpleasant, since hyphens appears in a pretty inconsistent fashion (or doesn't at all) on elements with italian language. Further, I cannot understand the documentation provided. My fault. Herein I report part of the directory structure of the project As you can see, and for what I understood, I loaded only few files from the original library, in order to hyphenate italian and english pieces of text (separated or mixed). The main language is still en, since I defined it in the lang attribute of the html element; for each element featuring italian content, I specified the language attribute accordingly (for mixed content, I used spans). In the head element of my base.html: <script src="{% static './hyphens/Hyphenopoly_Loader.js' %}"></script> <script src="{% static 'HyphenConfig.js' %}"></script> The HyphenConfig.js file, instead: $(document).ready(function() { var Hyphenopoly = { require: { 'en-us': 'ALL', 'en': 'ALL', 'it': 'ALL' }, paths: { patterndir: "./hyphens/patterns/", maindir: "./hyphens/" }, setup: { selectors: { '.hyphenate': { compound: "all", leftmin: 0, rightmin: 0, minWordLength: 4 } } } }; }); I also defined the hyphenate class in the … -

Connection Timeout on External API Call on Server but Works Locally
I have a Django 4.2.2 application running on Python 3.11.

How to order migration files across different apps in django?
I am working on a django project. After some time, I wanted to refactor the code. I wanted to create a new app and move some of my models to that app. Here's an example: Suppose I have an app named CategoryApp and two models in it named Product and Category. class Category(models.Model): ... class Product(models.Model): ... After some time of coding, I realized that I need a separate app for Product. So, I created a new app named ProductApp. And copied the Product model from CategoryApp to ProductApp. I managed all the foreign keys and relationships appropriately. Now, I need to create the migration files. First of all, I created a migration file for the app ProductApp (python3 manage.py makemigrations ProductApp) that just creates a new table productapp_product in the database. The migration file is named 0001.py. I applied this migration and a new table is created. Second, I created an empty migration file in the ProductApp (python3 manage.py makemigrations ProductApp --empty). The migration file is named 0002.py I modified the contents of the empty migration file to run SQL query to copy all the data from categoryapp_product table to productapp_product. I also added reverse_sql in case I need … -

Unique Constraint Failed In Upsert When Calling bulk_create with update_conficts
Im facing a unique constraint failed error with django. The objective of the api is, eithering creating or updating marks of the student, based on subject variation, exam_results and in bulk. For that, I've used bulk create with update conflicts flag. Here is the current model class Marks(Common): exam_results = models.ForeignKey( "ExamResults", on_delete=models.CASCADE, related_name="marks" ) subject_variation = models.ForeignKey( "SubjectVariation", on_delete=models.CASCADE, related_name="marks" ) student = models.ForeignKey( "Student", on_delete=models.CASCADE, related_name="marks" ) marks_obtained = models.FloatField() objects = BaseModelManager()class Marks(Common): now, when I do bulk create, it asks for unique fields, and since I only want to update marks if there is same exam results, subject variation and student in another instance. So, i add that to unique fields of bulk create. class MarksUpsertSerializer(serializers.ModelSerializer): class Meta: model = Marks fields = ("exam_results", "subject_variation", "marks_obtained") class BulkMarksUpsertSerializer(serializers.Serializer): marks = MarksUpsertSerializer(many=True) def create(self, validated_data): marks = [Marks(**item) for item in validated_data["marks"]] marks = Marks.objects.bulk_create( marks, update_conflicts=True, update_fields=["marks_obtained"], unique_fields=["exam_results", "subject_variation"], ) return marks but when I do this, it says there is no unique or exclusion constraint matching the ON CONFLICT specification. I assumed its because there's no constraint thats been provided to say that those fields must be unique together, so I added a constraint on … -

How do I correctly define the url in Django (error Page not found (404))
(I tried solutions provided in similar questions, but they didn't work). I am learning Django, and building the following project: My project is es. I have 3 apps called event, items_dashboard and item. Each event has one items_dashboard, and zero or more items. When the user is in /event/<event_id>/items_dashboard/index.html, there is a link to add a new item to event <event_id>. This opens a form /item/new/<event_id>. When I fill and submit this form, I get the following error: Page not found (404) Request Method: POST Request URL: http://127.0.0.1:8000/item/new/ Using the URLconf defined in event_site.urls, Django tried these URL patterns, in this order: [name='index'] event/ item/ new/<int:event_id> [name='new'] item/ <int:pk>/ [name='detail'] item/ <int:pk>/delete [name='delete_item'] The current path, item/new/, didn’t match any of these. Question: How do I correctly define the url for this scenario? ================================================================= Support material: My relevant urls.py files are as follows: es/urls.py: urlpatterns = [ path('', include('core.urls')), path('admin/', admin.site.urls), path('event/', include('event.urls', namespace="event")), path('item/', include('item.urls', namespace="item")), # path('', index, name='index') ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) item/urls.py: app_name = 'item' urlpatterns = [ # path('new/', views.new, name='new'), path('new/<int:event_id>', views.new, name='new'), path('<int:pk>/', views.detail, name='detail'), ] event/urls.py: app_name = 'event' urlpatterns = [ path('new/', views.new, name='new'), path('<int:pk>/', views.detail, name='detail'), path('<int:event_id>/items_dashboard/', include('items_dashboard.urls', namespace='items_dashboard')), path('<int:event_id>/item/', … -
Django: url transition doesn't work, how to fix it?
Good afternoon! I encountered this bug: when clicking on a link, the url changes, but the transition to another page doesn't work. To be more precise: There is a page that displays information about an article (test is the slug of the article): http://127.0.0.1:8001/articles/article/test/ url to go to the update page: http://127.0.0.1:8001/articles/article/test/update/ Composition of the urls.py file: urlpatterns = [ path('', views.index, name='articles_catalog'), path('article/<slug:slug>/<str:author>/', views.details, name='comment_creation'), path('article/<slug:slug>/update/', views.update_article, name='update_article'), path('article/<slug:slug>/', views.details, name='details'), path('new_article/', views.new_article, name='new_article') ] Link to go to: <a href="{% url 'articles:update_article' slug=article.slug %}" id="update_article" target="_self" rel="noreferrer noopener" class="thq-button-filled thq-button-animated" > UPDATE </a> The view itself: @login_required() def update_article(request, slug): print('OK1') article = Article.objects.get(slug=slug) tags = Tag.objects.all() if request.method == 'POST': print('POST') else: form = ArticleForm(instance=article) return render(request, 'articles/create-update.html', {'form': form, 'tags': tags}) As a result, when I click on the link, the url in the address bar changes, but the page itself - remains the same. Please advise me what I might have missed.
