How to show linked objects in Django Admin View?
I have two models that are linked by a foreign key relationship: class A(models.Model): q1 = models.CharField(max_length=60) q2 = models.CharField(max_length=60) ... class B(models.Model): b = models.CharField(max_length=60) a = models.ForeignKey("A", on_delete=models.CASCADE) In my admin site I have the A model showing, and ideally would like to keep it that way. Is there a way for me to within the individual A instances show the B instances? I have only been able to find solutions for the reverse (showing a dropdown of A instances in the individual B instances). -

How to pass variable from JavaScript to Django as part of url?

Passing values from Jquery with Ajax to Django views
I'm building an django app where user can organize notes in three columns "To Do", "Progress" and "Done" with drag and drop made with Jquery sortable. On screen load, notes are imported from database and put inside column matching their status values. After user changes, "save" button can be clicked.

Django MSSQL: Override Foreign Key Constraint Name Generation
I am attempting to create a database model in Django 3.0 using django-mssql-backend as by db backend for SQL Server 2019. The database uses multiple schemas for the tables included in it with some of the tables being non-managed (already exist), and others being created from scratch through migrations. To get multiple schemas working, I used a hack I found on another answer on here that suggested formatting the tablename as follows: class MyModel(models.Model): ... class Meta: db_table = 'schema].[table' This is so that the SQL compiles to have the wrapped square brackets that automatically form on the outside complete the schema/table definition. The problem with this is that ForeignKey objects have their constraint names generate using this table name which causes invalid constraint names arise, causing the migration to fail once the tables are done being created and it comes time for the constraints to be created.\ They generate like this: [schema1].[table1_colname_id_bc165567_fk2_schema2].[table_colname] Is there a way to override this behaviour? If this can be overridden by forking the backend and adding manual compilation code how would I even go about doing that? Otherwise, how can I have foreign keys in my models while using multiple schemas and fully utilizing … -
Cookies are blocked during development DRF and Vue app
I have Django Rest Framework API and Vue SPA frontend app. I deploy both of them in the DigitalOcean App platform. I use Session Authentication. My problem is that Session and CSRF Token cookies do not work during development when Django and Vue are served by their default servers. I guess it is because of the Same Origin Policy and other security stuff. In the production, everything is working fine when they are on the same domain. I do not have this issue earlier because I was using Token Authentication which I found out is not suitable for web Apps. I need some way of using session and csrftoken cookies during development on my computer. Is this possible with Dockerazing both apps (they are in separete repositories currently) and starting them with some reverse-proxy like Nginx so they will have the same domain? Or mayby some other way so i could develop and deploy such app easier? I cant find any information about this problem in the internet, so maybe I am missing something, or should do something differently? -
Django: how to redirect to page with list of newly created objects after form post bulk_create
I have a simple form that allows user to paste csv data with the goal to create multiple model objects at one go. The form method is 'post'. Action url is a method that calls the django `bulk_create` to create the model objects returning the pks. Goal: After submission, I want to redirect to page showing a list of the objects corresponding to the pks. Is that possible? I have tried: return render(request, "list_template.html", context={'object_list': objects_with_pks}), passing the model objects as context data to another template (but there would be danger of duplicate submission upon refresh) Redirect user to a model DetailView which contains the pk in the url (but I have more than one pks created) return HttpResponseRedirect to a new page with a success message (but I won't be able to pass the pks to the new page) Other ways that I've thought but could not find an answer Can I pass multiple pks in a url? Is there a way to transform a POST request to a GET? Can querysets in a model ListView instance be passed as parameters? I am fairly new to web development and posting questions on stackoverflow. Please comment if its unclear and … -

How to prevent deletion of instance from Inline in Django Admin correctly?
I have two models look like: class Client(models.Model): # some client fields class User(models.Model): # some user fields owned_by = models.ForeignKey(Client, on_delete=models.CASCADE) is_main_user = models.BooleanField() Also I made admin part. StackedInline for User and ModelAdmin for Client which includes UserStackedInline. My goal is prevent deleting User which has is_main_user==True. I've made signal handler for pre_delete from User and raise ValidationError("You cannot delete main user") when condition is true. But when I try to delete user in admin, I was getting 500 error. I've expected to get readable message in admin. How I can correctly handle ValidationError on instance deletion in StackedInline? Or am I incorrectly preventing a specific instance from being deleted? -
