Dynamic ModelChoiceField on template
I would like to have a ModelChoiceField that is dynamically changed by the user directly on the form. Basically I'm building a CMS and User has several templates at its disposal, however I'd like to display in my dropdown only the relevant templates to the kind of content it's producing. For example, we would have a first dropdown to select the content_type. We assume we pick article. Selecting this would update in a second dropdown list both including side_image_article.html and default_article.html. Here is a MRE : models.py class MyTemplate(models.Model): template_name = models.Charfield(max_length=80) content_choices = [("article", "article"), ("project", "project"), ("press_release", "press_release"), ("newsletter", "newsletter"), ("newsletter_web", "newsletter_web"), ("petition", "petition"), ("mailing_list_signup", "mailing_list_signup"), ] content_type = models.CharField(max_length=100, choices=content_choices, default="article") Each template is assigned a content type that is appropriate to the sort of content it's designed for. still models.py class MyBlogitem(models.Model) template = models.ForeignKey(MyTemplate, on_delete=models.PROTECT) body_text = models.TextField() content_choices = [("article", "article"), ("project", "project"), ("press_release", "press_release"), ("newsletter", "newsletter"), ("newsletter_web", "newsletter_web"), ("petition", "petition"), ("mailing_list_signup", "mailing_list_signup"), ] item_type = models.CharField(max_length=100, choices=content_choices, default="article") And the forms.py class MyBlogItemForm(ModelForm): template = ModelChoiceField( queryset=TopicBlogTemplate.objects.filter( content_type=???), empty_label=None) So here the goal would be to filter the template field using the content_type field, both being in dropdown lists. There are being loaded … -
Django FileNotFound image url
The idea is I want my form to upload an image with ImageField and then save a base64 of that image with post_save.

Sentry SDK Django set tag for event and raise
This is the current implementation I have: from sentry_sdk import push_scope def run(): with push_scope() as scope: message = "Failed" scope.set_tag("custom", "tag") raise Exception(message) But according to the docs the with-scope context manager will swallow the exception raised inside. The problem is I need this method run to actually raise an Exception so is doesn't send a response to the user. If I handle the flow and capture the sentry event in the with-scope context manager and raise later outside of the context manager, I will end up with duplicate events in Sentry ? from sentry_sdk import push_scope, capture_exception def run(): with push_scope() as scope: message = "Failed" scope.set_tag("custom", "tag") capture_exception(message) raise Exception(message) Is this really sending two events to Sentry and/or is there a better way to deal with this issue, maybe forcing sentry to ignore the raise at this point ? -

Publish and "Save Drafts" feature in Django
I am working on a Django Rest Framework B2B application with a React Frontend. The data is fed from a csv and then Analytics dashboards are rendered in React. Each Account ("User") is a company - and within a company, the app is used by the entire marketing team (say). Each company account has data unique to that co. and dashboard preferences unique to that company. An administrator is a human user who is some Manager / employee of a company (let's say, for example, Boeing, Nike etc) who has edit / administrator rights on behalf of the company. That "admin" makes some changes to the dashboard preferences and wants to "Publish" the changes so that rest of the employees (the rest of the Marketing team) of the company Account can view the updated dashboard. But maybe not yet, hence a "Save Drafts" feature. I'm not sure how to get these two features in the most industry-standard way in Django (DRF) - When I hit "Publish", the entire marketing team should be able to see the changes. (It's a B2B app). But when I save drafts, I should be able to view the changes (as admin) but not the rest … -

Is it possible to return a GET request after saving the post request to the database?

Making Django Function Work On HTML On Button Click
I'm trying to call a view so that it displays within a div on the page I already have existing rather than linking to a new page to post a comment. So far I've been able to bring up the div which shows after a button click and hides when pressed again. Ideally, when it shows the form for a comment should show yet at the moment it is only the submit button. I'm wondering how I could get this form to show up in this div as it does on the other HTML page. If there is any more required info let me know, just didn't want to give too much to look at.

Django custom decorator for redirections
I'm deploying a multi-domain platform in Django, with some model logic for performing redirections between websites. As the redirection mapping is going to get slightly bulky I'd rather decorate each view as opposed to replicate the code for redirections in every view (I'm sticking to function-based views for this project). As the logic could possibly be changed too, I need to have it all in one place and I'd really like to use a custom decorator for that. I've been trying different syntaxes in order to define a decorator and I'm getting all sorts of problems. https://pythonbasics.org/decorators/ I'm using the syntax I see here but I couldn't apply it to Django views at first. I'm using Django 3.2. This is the thread that most resambles my situation and which helped me get closer to the result I want Django custom decorator redirect problem however my decorator view still returns None instead of an HttpResponse object and I don't understand.

How to use regex in django query to get the shortest match?
I have some bunch of entries in a column of a Postgres database that looks like below Abcd/* Abcd/dir1/* Abcd/dir1/dir2/* Abcd/dir1/dir2/dir3/* I am using django ORM to access this information like below given_path = "/some/path" access_obj = Access.objects.get(dir_id=given_path) #dir_id is the column name Now given a path, I need to find the earliest match (any path after * is allowed, hence don't search further) and give the result back. What I mean is say a path is given Abcd/dir1/dir2, since my first entry itself is Abcd/* so I don't need to look any further and return the first row object itself. Currently I try to fetch using __icontains check like below access_obj = Access.objects.get(dir_id__icontains=given_path) But it would return all the matches and then I am unable to figure out how to target the first match (in this case) and query the object. I am aware django supports regex on queries but I am not sure what to apply here. Any help will be appreciated. -

Can I (safely) override Django settings in a server side wsgi.py?
I want to deploy two Django web-apps (individual domains) that share the same source code/repository and, hence, the same settings file. (Hosted on pythonanywhere by the way). The only difference between the two is that they should access different data bases (which I would usually define in settings.py or .env). As I see it, the only file that is unique to each web-app is their individual ...wsgi.py file (the one on the server not the one in the Django project folder). Thus, my idea is to use that file to specify each app's data base settings. Is it possible to (safely) override settings in a wsgi file? How would I do it? The current wsgi.py file looks like this: # +++++++++++ DJANGO +++++++++++ # To use your own django app use code like this: import os import sys # ## assuming your django settings file is at '/home/.../mysite/mysite/settings.py' ## and your manage.py is is at '/home/.../mysite/manage.py' path = '/home/.../...' if path not in sys.path: sys.path.append(path) # os.environ['DJANGO_SETTINGS_MODULE'] = 'core.settings' # ## then: from django.core.wsgi import get_wsgi_application application = get_wsgi_application() Many thanks for your help! -

Generate shareable link feature in Django?
I have a Django Rest Framework application that is fed in data from a csv. I then use React to create dashboards and Widgets from that data. I want to be able to generate a link to share a read-only version of any dashboard, much like in Google docs etc. I'm not sure how to go about doing that. Any help / pointers would be appreciated. Thank you!
