Element added to DOM has HTML / SVG attributes, but not the corresponding JS properties
I am using HTMX with Django to render a page which is basically an SVG with a lot of sticky notes () that you can move around on the page, like you might use for brainstorming. When you edit the text, htmx POSTs that back to a Django view which returns the updated content. This is the Django template for a single form: <g id="g1-{{form.instance.pk}}" hx-post="{% url 'architech:updatetech' form.instance.map.pk form.instance.pk %}" hx-swap="outerHTML" hx-trigger="focusout" hx-include="#fo-{{form.instance.pk}}"> <g id="g2-{{form.instance.pk}}" transform="{{form.instance.presentation|safe|default:"matrix(1,0,0,1,50,50)"}}" class="ui drags" draggable="true"> <foreignObject id="fo-{{form.instance.pk}}" height="203" width="319"> <form class="card" id="form-{{form.instance.pk}}" draggable="true"> <div id="header-{{form.instance.pk}}" class="card-header" draggable="true"> {{ form.name.errors}} {{ form.name }} {{ form.presentation }} <input type="button" value="x" hx-post="{% url 'architech:deletetech' form.instance.map.pk form.instance.pk %}" hx-swap="outerHTML" hx-target="#g-{{form.instance.pk}}" hx-trigger="click"> </div> <div id="body-{{form.instance.pk}}" class="card-body" draggable="true"> {{ form.notes.errors}} {{ form.notes }} </div> </form> </foreignObject> </g> </g> I've been using hx-swap="outerHTML" (and more recently "morphdom") to re-render and replace this block of code. When its reloaded, the same SVG/HTML doesn't get rendered correctly or respond to javascript. The key element is the second group, with id beginning g2. When loaded with the whole page, height and width are honored, and attributes like 'transform' are accessible with element.transform: # console interaction on initial state using 'save to a global variable' >temp1 … -
Static File Hosting, WhiteNoise not Updating - Django
I have a Django website in production and a while back I successfully hosted my static files using Whitenoise so I could use them in production. Now a few months later I want to add a new .png along with a bunch of other code and push it to production. I added the .png I wanted into my static files then deleted my 'staticfiles' folder in my code and reran python manage.py collectstatic. The files all collected like normal but when I ran my local server the page is no longer hosting that new .png using whitenoise. All the other static files that were hosting successfully before are STILL hosting fine now and being hosted by whitenoise. Its just the new one that is not being hosted through whitenoise. I checked the 'static files' folder and the new .png is in there fine with a copy of itself and additional characters added to its name like whitenoise usually does and like how all the other files are that are being successfully hosted. How do I update/refresh Whitenoise to acknowledge a new static file added? Thanks! -
How do I clean multiple files at once on a FileField with multiple attachments?
I am looking to throw a validation error if the user tries to upload more than 1 video file (they are allowed to upload more than 1 image). Here is the code for the field: media = forms.FileField( widget=forms.ClearableFileInput(attrs={"multiple": True}), label="Add image/video", required=False, validators=[validate_file_size, validate_file_extension], ) I am able to go through each file one by one using a validator on the field (checking the file extension of each file), or by using the clean function. -

How to find static files using regex in django in view?
I have django project that has a staticfile with the structure staticfiles/bundles/static/js/main.[hash of 8 random characters].js I want to get the name of main.[hash].js in my view.

user & request.user displaying different objects - Django
Not even sure where to begin here. Currently running into an issue where users are intermittently loading pages to find themselves "logged in" as other users (Templates rendering with wrong context). The error seems to come down to request.user showing the incorrect user while user has the correct user context. I currently use {{request.user}} in my templates and recognize that I could just switch to {{user}} but don't want to look over anything deeper that is going wrong. Any idea what would cause this? I've confirmed this issue is only contained to the site proper templates. The Admin site as well as some AJAX requests I have going to the server all seem to be processing the correct user context. EX. This is from a template render captured while the issue presented itself. UID is the user id from request.user.pk while User-UID is from user.pk I thought it could be the context processors, but I don't think my ordering is any cause for concern: "django.contrib.auth.context_processors.auth", "django.template.context_processors.debug", "django.template.context_processors.request", "django.contrib.messages.context_processors.messages", I've done my fair share of googling and head-banging so any help would be appreciated -

download to csv the result of a search in Django
I am trying to download a CSV from the result of a search. I have the following views: First is the search view def binder_search(request): if request.method == "POST": searched = request.POST['searched'] binders_searched = Binders.objects.filter(Q(description__contains=searched) | Q(step__name__contains=searched) | Q(status__name__contains=searched)) return render(request, "binder_search.html", {'searched': searched, 'binders_searched': binders_searched}) else: return render(request, "binder_search.html", {}) Then is the csv. This view creates the list of all items in the database. What I am trying to do is get the search result from the above view, and then create the csv file. I would end up with a CSV file that has only the search result in it. def binders_csv(request): response = HttpResponse(content_type='text/csv') response['Content-Disposition'] = 'attachment; filename=binders_result.csv' # create a csv writer writer = csv.writer(response) # designate the model binders = Binders.objects.all() # add column at the heading of csv file writer.writerow(['Item Code', 'Description', 'Item Type', 'Current Step', 'Current Status', 'Last change by']) # loop thru and output for binder in binders: writer.writerow([binder.itemcode, binder.description, binder.itemtype, binder.step, binder.status, binder.user]) return response I look around at different solutions, but none actually debugged me.

How to set up developing Django, JavaScript with Docker and static files? To get real time web page changes
Currently I have Docker container. The process with main.js: npm renders main.js and store it in static folder (out of the docker container) Docker compose and docker file collects static files in static-volume, including main.js Nginx serves main.js from static-volume But when I make changes to the source code, I can see the results only after restarting container and "docker volume prune" command.

Improving efficiency around Django's ORM and serialization while importing external data
I have a celery worker that periodically fetches data from an API that I need to be in sync with. I create or update a particular model instance depending on whether I have the external id stored already. However, as the API I'm syncing with has grown, this task has become increasingly expensive. Here's the relevant code: for d in api.fetch_items(): attempted_count += 1 try: existing_item = MyModel.objects.get(item_id=d["item"]) serializer = MySerializer( existing_item, data=d, partial=True, context={"company": company}, ) except MyModel.DoesNotExist: serializer = MySerializer(data=d, context={"company": company}) if serializer.is_valid(): serializer.save() imported_count += 1 else: logger.error(f"Invalid data when deserializing item: {serializer.errors}\nBased on: {d}") I think because the response is so long (often 50,000+ items), those queries make the task eat up lots of time. I'm hoping to get some suggestions on making this flow more efficient. Some things I've considered: Comparing the instances of MyModel via iterator() to the response the task receives to determine which internal items need to be updated or created (I don't even know if this would be faster) Bulk updating, though I'm not sure how to do bulk updates when the values that need to be updated for each item are different. Maybe an atomic transaction? I'm not even … -
