HTMX hx-target moves content down instead of replacing it in designated id
I am having the problem where my hx-target doesn't seem to be replacing the content where the target I point to. I'm using a a base html file that has a div with an id of requestcontent in it. All of my links, form actions and hx actions that I'm using point to this div for replacement. My initial access from an item on the menu sidebar works fine and gives results as shown here: Even when I click on the "Add bill" button the page renders correctly: However if I press close or save on this page when I return to the original page the top of the add page is still present: This is true from both my add and delete pages. The initial page that starts out the entire process is in billlist.html <div class="container shadow min-vh-100 py-2"> {% include 'acctsite/partials/messages.html' %} <h2>Accounts Payable / Bills Listing</h2> <div class="row" align="right"> <div class="col-10"></div> <div class="col-2 pb-1"> <button class="btn btn-primary btn-sm" hx-trigger="click" hx-get="{% url 'expadd' %}" hx-target="#requestcontent"> Add bill </button> </div> </div> <div class="row"> <div class="col h5">Date</div> <div class="col h5">Vendor</div> <div class="col h5">Description</div> <div class="col h5">Amount</div> <div class="col h5">Paid Info</div> <div class="col-1"></div> <div class="col-1"></div> <div class="col-1"></div> </div> <div class="row"> … -
How to Change django-autocomplete-light input box styling?
I have gotten the autocomplete to work with my Database and my front end, but the input widget looks slightly off. Is there a way to change the styling for the input? Also, is there a way to remove the initial dropdown, so after you click once, you can start typing and suggestions will appear? I am using the ListSelect2 Widget. The Select2Multiple looks like more of what I need but I want input to be only one. Current Widget Pre-Input Current Widget During Input Current Widget After Selection Desired Look (Select2Multiple Widget) I would appreciate any suggestions! -
Is there a way in Django where the superadmin can create normal users and the users gets an email with the credentials that was created for them?
I am having troubles about how to implement a scenario I am working on. I'm new to web dev so please pardon my naivety. I am using the default Django admin panel, where I have logged in with a super admin I created. The app doesn't have a sign up view so only the admin will be able to create new users. The normal users will them receive an email with their credential.

Django - I can no longer save form with dynamic formset
I would like your help with a problem that I can't solve or find a solution on the internet. I have a user registration form that was working correctly before. But feel the need to insert a dynamic formset. However, now with the formset when filling out and sending the form, no data is saved in the database and instead of being redirected to a list of users, I am redirected to the form again already filled with the data that failed to be sent and without showing any kind of error. -=-=-=-=-=-=--=-=-==-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Olá desenvolvedores, Gostaria da ajuda de vocês para um problema que não consigo resolver ou não encontro solução na internet.

NameError: name 'Message' is not defined (Django - Python3)
So, I'm creating an app in Django, and I can't seem to reference a class in the same file.

Creating credentials file on server via Dockerfile & Google cloud secret manager
I'm using Google cloud build for CI/CD for my django app, and one requirement I have is to set my GOOGLE_APPLICATION_CREDENTIALS so I can perform authenticated actions in my Docker build. For example, I need to run RUN python manage.py collectstatic --noinput which requires access to my Google cloud storage buckets. I've generated the credentials and it works well when simply including it in my (currently private) repo as a .json file, so it gets pulled into my Docker container with the COPY . . command and setting the env variable with ENV GOOGLE_APPLICATION_CREDENTIALS=credentials.json. Ultimately, I want to grab the credential value from secret manager and create the credentials file during the build stage, so I can completely remove the credentials from the repo. I tried doing this with editing cloudbuild.yaml (referencing this doc) with various implementations of the availableSecrets config, $$SECRET syntax, and build-args in the docker build command and trying to access in Dockerfile with ARG GOOGLE_BUILD_CREDS RUN echo "$GOOGLE_BUILD_CREDS" >> credentials.json ENV GOOGLE_APPLICATION_CREDENTIALS=credentials.json with no success. If someone could advise me how to implement this in my cloudbuild.yaml and Dockerfile if its possible, or if there's another better solution altogether, would be much appreciated. This is the … -
Filter using @property field django
I would like to filter based on @property field to generate a queryset. My model as below. `class PrHW(models.Model): po_duration = models.IntegerField(null=True) provision_start_date = models.DateField(null=True, blank=True) description = models.TextField(blank=True, null=True) @property def provision_end_date(self): provision_end_date = self.provision_start_date + relativedelta(months=self.po_duration) return provision_end_date` Since "provision_end_date" is a calculated field, it is not part of PrHW.objects.all() and hence I am unable create queryset using it as a filter option (eg, generate list of PrHW objects where provision_end_date is less than today - This generates error that "provision_end_date" is not a valid field; which was expected). I tried creating custom model manager but still I am unable to access either the @property field or other fields such as "provision_start_date" in the custom manager. May be this would be straingt forward but even after several searches, unable to get the hang of it. Any help is appreciated. -
Querying multiple schemas with django tenants
I'm writing this question because I have doubts about how to implement a scenario that we had not foreseen for my django developed application. Basically what I need is a way to allow some types of users, depending on their role, could access data that is in multiple schemas. So the approach that I had thought of was to create relationships between the "tenants", which define the database schemes, and detecting which of them a certain user belongs to, to be able to query all the schemes that are related to it. In the same way, this has some drawbacks, since this solution would require a lot of additional programming and concatenating querysets or working by adding the responses of the serialized data of each queryset of the aforementioned schemas could be inefficient. Thanks in advance. -
Django Rest how to show list of comment which belongs only from related Blog and Author?

Django – Efficiently fetch recursive categoryi structure
I have a model which looks like this: class Category(models.Model): name = models.CharField(max_length=50) parent = models.ForeignKey( 'categories.Category', null=True, blank=True, on_delete=models.CASCADE, related_name='categories' ) basically, in the parent field, it references itself. If a parent is set to None, it's the root category. I use it to build a hierarchy of categories. What would be the most efficient way to: fetch all the objects through the hierarchy display them in a template? For some reason, select_related does not seem to lead to performance improvements here. I also found this: How to recursively query in django efficiently? But had a really hard time applying it to my example. Would appreciate any help. Thanks! -

Get Old Objects, Update, and then return old objects
I have an APIView that looks like this: class GetNotifications(ListAPIView): serializer_class = NotificationSerializer def get_queryset(self): notifications = Notification.objects.select_related().filter(user=self.request.user).order_by("-created_at") Notification.objects.select_for_update().filter(is_read=False, user=self.request.user).update(is_read=True) return notifications What I'm trying to do is get all notifications that the user has. These include notifications that have been read and that have been not read yet (hence the is_read field). I'd like to return both the is_read and the not is_read notifications.Once those objects are received then an update will happen to change the not read notifications to is read. What this means is that any user who accesses this API through the site will mean that they've read their notifications so we can set is_read=True...however, my current code returns the objects after updating them. I want to return the old objects prior to updating hence me assigning notifications to the old objects before updating. I believe this is due to lazy loading on Django's part. Is there a way/better way to solve this? -
Issue With Nested Comments Using MPTT in Django and Django Rest Framework API - Result In Detail Not Found
I'm trying to create a nested comment system using MPTT but using Django Rest Framework to serialize MPTT tree. I got the nested comments to work - and these comments are added, edited, and deleted by calling Django Rest Framework API endpoints only - not using Django ORM DB calls at all. Unfortunately, there is a bug I couldn't figure out! Although the comments are added, edited, and deleted fine - but when a seventh or eighth comment is nested - suddenly the first-in comment or first-in nested comments would become [detail: Not found.] - meaning it will return an empty result or throw an unknown validation error somewhere which I couldn't figure out why. This results in when clicking on edit or delete the buggy comments becoming impossible - but the GET part is fine since these buggy comments do show up in the comment section (or should I say the list part returns fine). The image I'll attach will show that when I entered comment ggggg, the comment aaaa and bbbb will throw errors when trying to edit or delete them. If I delete comment gggg, comment hhhh will also be deleted (as CASCADE was enabled) - and … -
'Django OperationalError: no such table: users_portal' in Django

However, when I try to access this page, the following error is outputted onto the terminal: django.db.utils.OperationalError: no such table: users_portal This error has stopped my from accessing the 'Portal' page and therefore, has hindered me from progressing with my webapp. Any suggestions on how to get rid of this error? Would be highly grateful and open to all suggestions! I have already tried to make the migrations, and have them migrated. I have also attempted the --fake migrations and unfortunately none of them have yielded to the result I expected. -
