Django - No such column: rowid when migrating Spatialite database
I am trying to create a database using GeoDjango, but when I try to migrate the database I get "error in trigger ISO_metadata_reference_row_id_value_insert: no such column: rowid".

Migrate Custom Field Renderer from Django 1.8 to Django 3.2
I am trying to migrate a custom field renderer in a Django 1.8 form to Django 3.2. The form looks like this: class SomeEditForm(forms.ModelForm): job_uuid=forms.CharField(widget=forms.HiddenInput()) class Meta: model=Job fields=('status',) widgets={'status': forms.RadioSelect(renderer=BSRadioFieldRenderer)} So as it seems there is no Rendermixin anymore which accepts a renderer in its def init(). I have read the new source code and see that RadioSelect is now a subclass of ChoiceWidget. I cant get my head around to inject my old renderer into the new structure. Can someone please point me into the right direction? Thanks for your help! :) -

Django Rest Framework api: bulk_create assigning a str to the primary key and a number to my str field
I'm creating a basic Pokemon API for practise purposes, where my models include: Card, Expansion and Type (fire, water, bug, ice, etc.) I'm trying to run a script to populate the "Type" database table but I get weird results, where the type name field actually seems to contain the primary key value and the ID field contains the actual name, when it should be the other way around.

HTML - How to auto refresh the messages of a Chat-App
I'm working on a Chat-App with Django in Python. I tried some changes to auto refresh the messages of a chat but I had some problems: First time I tried: I used a javascript reloader for the div of the chat (but doing this, the send-message text input clears every time the auto refresher plays.) Second problem: the chat reset the height of the scroll every time the auto refresher plays. So I'm looking for a solution to refresh only the chat and keeping the scroll, without affecting other elements such as the text input. Here's the "chats.html" file: <div class="container-fluid h-100" style="posistion:absolute; margin-left:60;"> <div class="row justify-content-center h-100"> <div class="col-md-4 col-xl-3 chat"> <div class="card mb-sm-3 mb-md-0 contacts_card" style="max-height:700;min-height:700"> <div class="card-header"> <div class="input-group"> <input type="text" placeholder="Search..." name="" class="form-control search"> <div class="input-group-prepend"> <span class="input-group-text search_btn"><i class="fas fa-search"></i></span> </div> </div> </div> <div class="card-body contacts_body"> <ui class="contacts"> {% for group in groups %} <a href="/chats/{{ group.event_name }}/" style="text-decoration: none;"> {% if group.event_name == current_group.event_name %} <li class="active"> <div class="d-flex bd-highlight" > <div class="img_cont"> <img src="{{ group.event_img.url }}" class="rounded-circle user_img"> <span class="online_icon"></span> </div> <div class="user_info"> <span>{{ group.event_name }}</span> <p>Kalid is online</p> </div> </div> </li> {% else %} <li class=""> <div class="d-flex bd-highlight"> <div class="img_cont"> <img … -
Execute Celery task after Django model timestamp has passed
I am trying to build a Django app that reacts to certain events, and then after X amount of time, executes a celery task. Users with permissions are given the option of either vetoing the action, or expediting the action. I am using Django 4.1 and Python 3.10. Veto does not need to take effect immediately, as the celery task will just check for it once it runs. Expedite does need to take effect immediately, but must require more than a single user to vote on it. Votes may have their "expiry time" changed by an admin, and the celery task should change the eta accordingly (or the task revoked and a new one put in the queue, with the updated eta). The work must be done in near-real-time, so no having a daily task that checks for expired votes. An example might make it a lot more clear: Bob has quit his job, and therefore his user accounts and access need to be revoked. A celery task that does just that, is put into the celery queue, with an eta of 2 days into the future (the timestamp is also logged in a Django model). HR is notified that … -

Can I override Django rendering checkbox inputs inside a label?
I'm trying to render a form which allows for multiple selections via checkboxes. I've tried with django-multiselectfield (which I was already using) and the native CheckboxSelectMultiple widget. If I have a simple form like so: FAVORITE_COLORS_CHOICES = [ ('blue', 'Blue'), ('green', 'Green'), ('black', 'Black'), ] class SimpleForm(forms.Form): favorite_colors = forms.MultipleChoiceField( required=False, widget=forms.CheckboxSelectMultiple, choices=FAVORITE_COLORS_CHOICES, ) And if I render with widget tweaks like so: {% render_field form.favorite_colors %} <div id="id_favorite_colors"> <div> <label for="id_favorite_colors_0"> <input class="form-control" id="id_favorite_colors_0" name="favorite_colors" placeholder="Your Name" type="checkbox" value="blue" /> Blue</label> </div> <div> <label for="id_favorite_colors_1"> <input class="form-control" id="id_favorite_colors_1" name="favorite_colors" placeholder="Your Name" type="checkbox" value="green" /> Green</label> </div> <div> <label for="id_favorite_colors_2"> <input class="form-control" id="id_favorite_colors_2" name="favorite_colors" placeholder="Your Name" type="checkbox" value="black" /> Black</label> </div> </div> This is causing problems for the way I want to render my form. Is there any way I can force Django to output the input and then the label, so the html would be like so: <div id="id_favorite_colors"> <div> <input class="form-control" id="id_favorite_colors_0" name="favorite_colors" placeholder="Your Name" type="checkbox" value="blue" /> <label for="id_favorite_colors_0">Blue</label> </div> <div> <input class="form-control" id="id_favorite_colors_1" name="favorite_colors" placeholder="Your Name" type="checkbox" value="green" /> <label for="id_favorite_colors_1">Green</label> </div> <div> <input class="form-control" id="id_favorite_colors_2" name="favorite_colors" placeholder="Your Name" type="checkbox" value="black" /> <label for="id_favorite_colors_2">Black</label> </div> </div> I haven't found an easy answer to this and most … -

Django installed but not able to locate module
I'm using a django web project template and its my first time creating one. I had to pip install django but the code that is existing still isnt referencing it and instead its giving a green squiggle under neath anything referencing Django. I created another blank file and ran a line with import django and it removed the green squiggles and worked. But then I dont know what changed and now its back to how it was before and even running import django before my code wont fix it like last time. It still gives the error below. I havent typed any new code to this template so there should not be any errors with the code provided. I tried first to add a new empty python file and import django. It worked the first time but went away and didnt work the second time. I tried to type import django before each file that uses django functions. It didn't remove the squiggles. From what I can tell when I run the whole file it pulls up a website with django on it and does not error out. -
Django Microservices using kubernetes, rabbitmq, docker, postgres
I'm curious about how to establish communication between Django microservices while also implementing authorization and permission protocols through a JWT authentication microservice. While I understand the general concept of how this is done, I'm unsure about the technical specifics. that's why i'm looking for guidance on developing microservices in Django using RabbitMQ and Kubernetes. Can you recommend a tutorial or someone who has experience with this. I've built a JWT microservice using Djoser, and I have another microservice that requires authentication and the user ID of a logged-in user to send requests. What's the best approach to achieve this? My initial idea is to pass the JWT token as an Authorization header in the requests from the second microservice to the first microservice. The first microservice should then verify the token and extract the user ID from it, which it can send back to the second microservice to perform user-specific operations. However, I'm unsure about the technical implementation of this approach. Should I use Django's built-in authentication middleware to check the Authorization header in the incoming requests to the second microservice? Is there a better way to achieve this? Any insights or examples on how to securely communicate between Django … -
Pycharm does not recognize Django no matter how many times I install it
I'm new to programming, so please bear with me, I have a hard time understanding what my problem even is many times, let alone explain it. I am attempting to edit a Django app in Pycharm. I have managed to set up a virtual environment, then installed Django in that environment using pip in the terminal, but Pycharm still seems to treat references to Django like they're errors. Here's what it looks like in Pycharm This ends up giving me issues where my virtual environment won't run. I feel like I'm very close to finally getting this to work, but something is wrong and I don't know why. Any help would be appreciated, thanks. I tried looking up Django plugins to install through Pycharm's Marketplace section, and none existed. I then installed Django into my virtual environment using the terminal and pip, and it still doesn't recognize Django. I get error messages whenever I try to run my Django App in the virtual environment, I get error messages. -
How to add additional choices to forms which is taken from a model in django
As in the topic is it possible to add choices to the forms that take from the model. forms.py class BookGenreForm(forms.ModelForm): class Meta: model = Book fields = ('genre',) models.py class Book(Product): GENRE_CHOICES = ( ('Fantasy', 'Fantasy'), ('Sci-Fi', 'Sci-Fi'), ('Romance', 'Romance'), ('Historical Novel', 'Historical Novel'), ('Horror', 'Horror'), ('Criminal', 'Criminal'), ('Biography', 'Biography'), ) author = models.CharField(max_length=100) isbn = models.CharField(max_length=100) genre = models.CharField(max_length=100, choices=GENRE_CHOICES) I care about adding add-ons for selection, such as alphabetically, by popularity. I can handle the creation of a view. At the same time, I would not like to just add these options in the choices model unless it is possible that later in the panel the user does not have the option to add as a genre of popularity, etc. Thank you all very much. I have an idea to make individual forms.Forms for everyone and re-create elections in them but I don't think it would be a pretty way to do it
