Django: How To Pass Some Fields Into A Choice List
I have a model that holds the categories of items which are all BooleanFields. I want to display these categories in each post but there are too many to show so I want to make a form that allows the user to select 5 of their selected categories to display in the posts and then it will say (+ 5 more) or something like that. So is there a way that i can pass only the categories of which the value is true as choices in a ChoiceField? -

How to choose (not upload) file from server in admin (Django)
I need to display icon(representing the type of the document inside the post) along with each post. There are hundreds of posts each year. There are about a dozen types of documents hence I need that much icons. The problem is that if I use models.ImageField it will upload a new image each time a post is created, and I will end up with bunch of same icons pretty soon. So I am wondering how to implement the following logic: preview_icon -> choose from server upload_icon -> If the wanted icon does not exists on the server then upload and choose it from server via preview_icon field. My initial idea is to make a new model: class PostIcon(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name="icons") post_icon = models.ImageField(upload_to=f"path") So you can connect icon to post. But I am wondering if there is a way to implement the first logic I mentioned, because it would be much neater. Thank you. -

Modal Form Connected to SQLite3
I have the following code that is purposed to display a table of data and allow the user to add a new row by clicking a +New button, which opens a modal with the correct form, and then the user hits submit and the new row saves in the table.

django_neomodel fails to connect to a running database while neomodel works
I made these setting on settings.py, as directed on Getting Started: NEOMODEL_NEO4J_BOLT_URL = os.environ.get('NEO4J_BOLT_URL', 'bolt://neo4j:password@localhost:7687') INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django_neomodel', 'utils' ] But I only get this error with python manage.py install_labels: neo4j.exceptions.ServiceUnavailable: [SSLCertVerificationError] Connection Failed.

Adding a View to Django
I am trying to convert the django tutorial app into my own, and with that I need to add a few different views.

Vue error "Templates should only be responsible for mapping the state to the UI."
I'm using Django webpack-loader to load VueJS components inside of my Django templates, basically i have the following django template: {% load render_bundle from webpack_loader %} <!DOCTYPE html> <html lang="en"> {% load static %} {% block content %} <head> ... </head> <body> <div id="app"> <div id="someDjangoStuff"> </div> <someVueComponent></someVueComponent> <anotherVueComponent></anotherVueComponent> </div> <body> {% endblock %} </html> So basically what i'm doing here is using Django to render the template and all the html in the template, then inside the template i'm injecting Vue components for stuff that requires more interactivity. The problem is that, in my console, i'll get the following error: [Vue warn]: Error compiling template: Templates should only be responsible for mapping the state to the UI. I'm sure it's because i'm loading the Vue app and inside the app i'm also loading other html. Now this error doesn't have any repercussion, everything seems to work without any problem, but i wanted to clarify a bit: Is there any way to suppress the error or do this in another way without getting the errors? Can it create problems because it's not how i should use Vue? -

Python version mismatch for Azure Web App
I have created a web app on Microsoft Azure and choosen Python 3.8 as configuration. Then I set up a deployment pipeline on Azure DevOps which deploys a django app into the web app. The deployment itself also runs fine, artifacts are copied and unzipped. But the installation of the requirements is giving me a hard time. On the Configuration section for the Web App on Azure portal I defined "Python 3.8" in the general settings. And in the Azure DevOps pipeline the deployment task is configured to use "PYTHON|3.8" as runtime stack. But still the post deployment actions do fail - and this as it looks like is caused by the Kundu component which executes the task and itself is running python 3.5 (python3) and python 2.7 (python). The pip installation for django 3.1.4 then fails with error and I am getting warnings about end of life python 3.5. Here's deployment step and full output of it #Your build pipeline references an undefined variable named ‘Parameters.ConnectedServiceName’.

How can you connect Django code with Python?
