Response returns code=415, message=Unsupported Media Type in Android-Rest API
I am trying to implement a user login in Android using Kotlin. In the backend runs Django. The API is created in RestFramework. The API works fine when tested in a browser.

Trying to create a detail view with a list in the view with a sublist for each item. And I can create a item for every item on the same view
I am trying to finish this feature of my Django project. I have already created a list view and I am able to click on a topic on the list view and go into its detailed view. Once I am on that topic's detailed view there are a list of items that are associated with this topic. At the top of the page I have a form that when submitted will create an item and put it at the end of the item's list on the same detail view. For each item there are a list of subitems. For each subitem I am trying to create a submit button for it. So when I do click the submit button that subitem will be appended to the end of the list it was created under. Everything looks good but when I try to create a subitem it doesn't create the subitem for the right item. I hope this made since, can anyone point me in the right direction please??

Django Querysets - Objects including entire set in ManyToMany
I have a model, Respondent, related to another model Questionnaire via a ManyToMany field named finished. I have a set of four Questionnaire objects and would like to retrieve all Respondent objects that have a finished relationship with all four. I would also like to retrieve the inverse: Any Respondent object which doesn't have a finished relationship with all four selected Questionnaire objects. I've been looking through the docs, and haven't found something that works for me. I am able to get all of the Respondent objects that match at least one of the Questionnaire objects with Respondent.objects.filter(finished__in=questionnaire_queryset) but that's as far as I've gotten. -

Why my django project servers static files from two URLS?

How to add a SQLServer Full Text Search in Django QuerySet?
In Django, one can use full text search natively when using Postgres. However, when using it with SQL Server (and django-pyodbc-azure) there is no simple way to do it (as far I know). To do a full text search in SQL Server you use the CONTAINS(column, word) function as described in the docs, but Django ORM contains do: LIKE '% text %'. I did find two alternative methods to bypass this problem. One is using RAW SQL the other is using django extra. Snippet using django raw SQL: sql = "SELECT id FROM table WHERE CONTAINS(text_field, 'term')" table = Table.objects.raw(sql) Using django extra: where = "CONTAINS(text_field, 'term')" table = Table.objects.extra(where=[where]) There is two problems with it: Raw queries are harder to mantain. Django docs. recommend against using the extra method. So I want to know if there a better way to do this, using "pure" django ORM if possible. -

Authenticate VueJS app to Django DRF back end using sessions
Good afternoon, I am writing an app structured with two docker containers. Docker1 is the front end VueJS app, Docker2 is the backend Django DRF API. I would like to manage access using Sessions (NOT JWT's). I am having trouble finding resources to help me get started on this approach. Does anyone have any good resources on how to interact with authenticating and managing Django sessions over DRF? Most of the examples use a DJango template form to do initial authentication which is not an option in this case. Thanks for your help. BCBB -

Django model with dynamic fields based on foreign key
I am trying to implement a model where only a subset of the fields should be presented in forms, based on a foreign key in the model. The total number of fields is relatively low (~20), but may change frequently with different values of the foreign key. I would like to use something like single table inheritance, but with a single model (no inheritance). I looked at existing packages eav, dynamic models... but they did not seem to fit my needs. I part of the requirement is that I would like to query the models by sql without too many joins. Here is a use case representing applications to grants based on a request for application (rfa). The rfa is entered in the admin by staff and the applications are made by end users. application class rfa (request for application): foreign key field_1 ... field_20 rfa class: app_fields (coma separated list of field names) In the forms, only the fields in app_fields should be visible for a particular rfa. I have the rfa part covered with django-separatedvaluesfield and I was wondering how to implement the application pages so that they work with generic views in the frontend and admin, and … -
