Stencil setup: resolve, rollup version
I have two problems, both related to setting up my project. The ultimate goal is to build some web components that communicate vis OSC using node-osc. My first attempt to set up the project and create a component that uses node-osc resulted in the following message: Bundling Warning UNRESOLVED_IMPORT 'node-osc' is imported by ./src/components/r-channel/r-channel.tsx, but could not be resolved – treating it as an external dependency This gave me a successful build, but my components don't render, so I assume it's not actually all that successful. After some reading, my guess is that I should at least try plugin-node-resolve. I've installed and added to my stencil.config.ts, and am now seeing: Rollup: Plugin Error Insufficient rollup version: "@rollup/plugin-node-resolve" requires at least rollup@2.78.0 but found rollup@2.42.3. (plugin: node-resolve, buildStart) ...although my package-lock.json seems to indicate that I've got rollup@2.79.1 installed. -
Django monolith: How to render front-end while still loading one function from backend
I have a django monolith project; however, one of the objects (a graph) that I pass to the template context to display in the html is slow to load. I'd like to have the rest of the page render first, while this function is still running/loading. That way, users can see the rest of the page while the graph is still loading. Thoughts on the best approach to this? I tried creating a custom tag to load the graph, but the browser still waited for the everything to load before showing anything on the page. I'm wondering if some type of javascript call would accomplish this. -
How to create SO like tags in django?
Given a form, I need it to have tags (preferably) or any form which enables multiple selection with simple search/autocomplete. Something similar to SO tags will do: -
Bootstrap 5.2 Modals not appearing when using docs example

querying database to give specific need in Class Base View doesn't work

Django Regroup with tables and boostrap collapsible menu
I am trying to mix regroup (within a table) with bootstrapp's collpasible menus. I have a long list of product with categories. I was hoping to list the categories and leave the option for the user to look at the product within them by simply clicking on the category title. Example: How the data looks Category 1 Prod1 Prod2 Prod3 Category 2 Prod1 Prod2 Prod3 How I want it to look on the front end Category 1 Prod1 Prod2 Prod3 Category 2 My logic I thought if I was to input data-target="#category" in the grouper(category - first row) and then wrap the list of products within the category in <div id="category" class="collapse">, this should do the trick. For some reason the table seem to impact the way how regroup works. Any advice on how to user django regroup in a table, using boostrap collapsible menus? (I did find an alternative using JQuery (Django roll-up (collapsible) menu), but ideally would like to find out why this is not working) template {% regroup categories by category_menu as category_menu_list %} {% for category_menu in category_menu_list %} <table class="table"> <tr> <th></th> <th> <a class="button-account btn-block mybtn tx-tfm" data-toggle="collapse" data-target="#category">{{category_menu.grouper}}</a> </th> </tr> <div id="category" class="collapse"> … -
Wagtail permission for different user pass
in my wagtail app, I have a model that I want to only allow certain types of users to view that model. In django I would just inherit UserPassesTestMixin. In wagtail, I will allow it based on a session data. If request.session.dados_usuarios.bu == 'Corporate KO', he will be able to view the page. I'm new to wagtail, is it possible to do this? In django I would do it like this class SomeView(UserPassesTestMixin, TemplateView): ... def test_func(self): return request.session.dados_usuario.bu == 'Corporate KO' My model in wagtail app class IframePage(Page): iframe_url = models.URLField() fabricantes_com_acesso = ParentalManyToManyField( Fabricante, blank=True, verbose_name="Fabricas com Acesso" ) content_panels = Page.content_panels + [ MultiFieldPanel([ FieldPanel('iframe_url'), FieldPanel('fabricantes_com_acesso'), ], heading="Informações Principais"), ] -
Why does the number of bytes in this buffer change from the original size when dealing with images?
So i'm looking at some image resizing code in our code base, and i've noticed that after passing an image through PIL the number of bytes of the image increases by just under 2x. I've gutted most of the code out for the purpose of this demonstration just so I could isolate the case: import io from PIL import Image from django.core.files.base import ContentFile def size_test(content_file: ContentFile): with content_file.open("rb") as file: file_bytes = file.read() print("original size of bytes: %s" % len(file_bytes)) image = Image.open(io.BytesIO(file_bytes), formats=["JPEG"]) with io.BytesIO() as buffer: image.save(buffer, format="JPEG") buffer_bytes = buffer.getvalue() print("new size of bytes: %s" % len(buffer_bytes)) Calling the above with the following code, loading in a JPEG file of known size: with open('10mb.jpg', 'rb') as file: cf = ContentFile(file.read()) utils.size_test(cf) Here is the output: original size of bytes: 10174706 new size of bytes: 19538695 Maybe i'm missing something glaringly obvious, but i'm not sure what makes this image's bytes increase by 9MB in memory, unless it's to do with JPEG compression? Maybe by loading the JPEG into memory we are uncompressing it? Just tried this with a 1.7MB PNG file (changing the relevant formats in the original function): def size_test(content_file: ContentFile): with content_file.open("rb") as file: … -

Use password hash created in GO on Django admin auth doesn't work

Django-Channels sending messages from external processes with auth
I'm using Django-channels 4 to build a simple chat website where users can join any random channel and start chatting. I have AuthMiddleWare in asgi.py application = ProtocolTypeRouter( { "http": django_asgi_app, "websocket": AllowedHostsOriginValidator( AuthMiddlewareStack(URLRouter(client.routing.websocket_urlpatterns)) ), } ) Now, only logged in users can establish WS connection since its using cookie. BUT now what if I want to send a message to any channel from outside of my django app?. Say that could be from a python script running in same machine using websockets lib. In this case i should have; A session within WS header of the external script which won't expire so the script can use it all day long and hence auth is handled smoothly Identify and allow this external script to send message to any channel. I have seen Channels Custom Authentication where we can add token via the WS header. But i really want to use the existing session auth comes out of the box BUT allowing my special client to connect to the WS with say some sort of special cookie which won't expire (if that method exists). Tried copying cookie from a logged in user's WS header and adding in my script does allow … -
Hot to add buttons (links) to Geonode Menu bar using geonode-project 4.1.x?
I just install Geonode-project 4.1.x and try to follow the official documentation (https://docs.geonode.org/en/4.x/devel/workshops/index.html#customize-the-look-and-feel) to customize the look and add some Links (buttons) to the navigarion bar.

Geonode is still showing the same buttons (Dataset, Maps, etc). My intention is to add (I am saying add, not override) buttons to the Navigation Bar, so i can access the new views I have created for geonode project. I am using geonode-project 4.1.x. Documentations appears to be outdated. -
