django 2.2.5 URL regex in url path
I would like to support the above views in a single view in url ...in my search I came across [this post][1] which is no longer supported and all the tutorials i've found have been outdated, which demonstrate how to accomplish the task in django 1.8.3. In 'products/views.py' I have created a views for products and details. ProductListView will display all products, while ProductDetailView will display a single product detail (title, description, price etc). products/views.py class ProductListView(ListView): queryset = Product.objects.all() template_name = "products/list.html" class ProductDetailView(DetailView): queryset = Product.objects.all() template_name = "products/detail.html" products/urls.py include path to the views for ProductListView and ProductDetailView. ProductListView appears to be correct. ProductDetailView is incorrect! I'm getting the following warnings: WARNINGS: ?: (2_0.W001) Your URL pattern '^products/(?P\d+)/$' [name='details'] has a route that contains '(?P<', begins with a '^', or ends with a '$'. This was likely an oversight when migrating to django.urls.path(). ecommerce.py/urls.py is where i've included products and details urls ecommerce/urls.py: from django.conf import settings from django.conf.urls.static import static from django.contrib import admin from django.urls import path, include from .views import home, about, contact urlpatterns = [ path('admin/', admin.site.urls), path('', home, name='home'), path('about/', about, name='about'), path('products/', include('products.urls'), name='products'), path('products/', include('products.urls'), name='details'), path('contact/', contact, name='contact'), path('account/', … -

Wagtail: How to override default ImageEmbedHandler?
I've been having some trouble implementing Wagtail CMS on my own Django backend. I'm attempting to use the 'headless' version and render content on my own SPA. As a result, I need to create my own EmbedHandlers so that I can generate URL's to documents and images to a private S3 bucket. Unfortunately, though I've registered my own PrivateS3ImageEmbedHandler, Wagtail is still using the default ImageEmbedHandler to convert the html-like bodies to html. Is there a way for me to set it so that Wagtail uses my custom EmbedHandler over the built in default? Here's my code: from wagtail.core import blocks, hooks from messaging.utils import create_presigned_url class PrivateS3ImageEmbedHandler(EmbedHandler): identifier = "image" @staticmethod def get_model(): return get_user_model() @classmethod def get_instance(cls, attrs): model = cls.get_instance(attrs) print(model) return model.objects.get(id=attrs['id']) @classmethod def expand_db_attributes(cls, attrs): image = cls.get_instance(attrs) print(image) presigned_url = create_presigned_url('empirehealth-mso', image.file) print(presigned_url) return f'<img src="{presigned_url}" alt="it works!"/>' @hooks.register('register_rich_text_features') def register_private_images(features): features.register_embed_type(PrivateS3ImageEmbedHandler) -

Python warnings to exceptions in Django tests with ignore
I'm attempting to run Django unit tests using: python -We -W ignore:DeprecationWarning -W ignore:UserWarning manage.py test However, this doesn't successfully ignore these warning classes, and instead only respects the -We flag, raising all warnings to exceptions.

Multiple File Upload inside a inlineformset
Hi I would like to know if it's possible to have a multiple file upload field within a formset. The structure is as following: I have a parent model who get a one to one relationship with one of his possible child. The child have several inline formset with other specific models. And one of those formset need to contain a multiple file upload. They are all edited in the same view. The parent and the related child get created before going to that edit view. This is a capture of my database structure (there is a missing table on the right): Just to give you a vague idea I have: a Task model which have a 1to1 to a GeneralApplicationTask which have a many to one relationship with GeneralApplicationProperty(this is what is used in the inlineformset) So for each GeneralApplicationTask Form I have some fields and then several formset containing property information and each need to contain a multiplefile upload. The problem I am facing is, if I create a modelForm to manage the files and create a Mt1 from the GeneralApplicationProperty model, then I cant properly save the files because I need to know which form (and the … -

How to send data in POST fetch request from one domain and process request on server listening on different domain?

There is a issue of CORS which I have patched using django cors headers app. I am able to use GET APIs like this and that is working fine till now. fetch("http://localhost:8000/api/comments", { method: "get" }).then((response)=> { console.log("got response"); return response.json(); }).then((comments) => { console.log("got json", comments); this.setState({ comments: comments }) }).catch((error)=> { console.log("error", error); }); Second I have POST API where add commenter's name, I have tried different variations to call this API, but not with much success. All the variations have one issue and that is, the request body is empty, browser network tab and logs in views.py method agree on that. var headers = new Headers(); // Add a few headers headers.append('Content-Type', 'application/json'); headers.append('X-Requested-With', 'XMLHttpRequest') let payload = { "first_name": first_name.value, "last_name": last_name.value }; var data = new FormData(); data.append( "json", JSON.stringify( payload ) ); const request = new Request("http://localhost:8000/api/user", { method: 'POST', mode: … -

clamav timing out when scanning stream for large file
Have a React/Django app that a small group of clients use to submit files to us. Using react-dropzone for the file upload, without any maxSize specified, so it should be react-dropzone causing the issue. The file I'm working with is an Excel file of about 160MB. When the files are uploaded, clamav (called from Django) scans the files in stream before writing to disk. I have run into issues in the past with clamav and default maximum file sizes being removed, so I have those either removed or set very high. Initially it was timing out after 30 seconds. I looked at the scan.conf for anything related to time and 30, which brought me to IdleTimeout which defaults to 30. I changed it to 360 and now it times out after about 90 seconds. Nothing in the scan.conf has a 90 associated with it, so I'm puzzled as to what else I could change to get this to work. These are settings I've changed and the value I have them at: LogFile /home/log/clamd.log LogTime yes LogSyslog yes LogVerbose yes LocalSocket /var/run/clamd.scan/clamd.sock StreamMaxLength 2048M ReadTimeout 360 IdleTimeout 360 MaxScanSize 0 MaxFileSize 0 OnAccessMaxFileSize 0 # 0 disables any limit Any suggestions … -
