How to fix this django+bootstrap carousel bug

Django : Structure of the API withe redirect functions or decorators
I am a Newbee on Django and I am not sure of the structure of my API. There is a sidebar with a list of apps. I have one that is to upload files. I want that when the user click on the upload files app it appears a page with a dropdown list to choose a client. Then when it selects a client, it redirects to the upload page with the value of the client selected because this value has to be stored in the database when a file is upload and show in the templates too. When the user wants to change of client, he has to return to the previous page and change the selected client How should I do that ? What is the most efficient and logic in terms of views and decorators ? Here is what I did. I think that it is not efficient.The user clicks on the upload url, it brings to the upload view where the id_client selected is initialize to None. So it redirects to the selectclient view where the user selects the client and brings back to the upload view def upload(request, idclient = None): if idclient == None … -
Filling a complex object from database in Django
I am trying to figure out how I can create a complex object in Django, using data retrieved from different, joined tables in a database, without having to do a series of explicit queries and then manually putting it all together. Lets say I have three tables that look like this **parent** - id - name **attribute** - id - parent_id *(ForeignKey)* - name - value **modifier** - attribute_id *(ForeignKey)* - value - duration So, every parent has an arbitrary number of attributes, and each attribute can have an arbitrary number of modifiers, each identified with ForeignKeys in their respective models. From entries in these tables, I would like to build a Python object that has the following structure **object** - id - name - attributes {} - name : (value, modifiers[(value, duration), (value, duration), …]) - name : (value, modifiers[(value, duration), (value, duration), …]) - … What is the best and most efficient approach to achieving something like this in Django? Is there even a way or will I have to run multiple queries and fill the object in discrete steps? -
Django Autocomplet Light select2 widget not working on ios
I have a project that uses DAL and I thought was all well and good till a friend told me the Select2 widget was broken. Turns out it does not work on any iOS(iphone, ipad) device in safari or chrome. It works on my Google pixel and macOS. Below is a picture of what it looks like on iOS. But basically eh problem is you cannot type into it. It just shows a blank list. Has anyone else run into this. Any idea of where to start would be great. I looked at the css for the select2 in DAL but could not see anything that would be device specific. I am using bootstrap as well and in my search ran into something where select2 did not play well with bootstrap and will try and do some testing of that tonight. Any direction would be appreciated. -
How to make existing columns empty in Django

How to filter QuerySet depending on fields of a reverse foreign key related model?
I have two following models: class Tour(models.Model): name = models.CharField(max_length=100) description = models.CharField(max_length=3000, blank=True # some other fields here and class TourDatesInfo(models.Model): departure_date = models.DateTimeField() return_date = models.DateTimeField() tour = models.ForeignKey(Tour, on_delete=models.CASCADE, related_name='dates') Tour model has a one-to-many relationship with a TourDatesInfo, so that one tour may have multiple different sets of departure/return dates. What I try to achieve is to be able to filter the tours QuerySet depending on their set of TourDatesInfo, preciesely on whether each tour contains departure/return pair that satisfies specific conditions, e.g., get all tours that have at least one TourDatesInfo with departure_date > 2022-04-12 and return_date < 2022-05-01. I can write an SQL query to perform this, something like SELECT * FROM tours_tour tours WHERE tours.id IN (SELECT DISTINCT tour_id FROM tours_tourdatesinfo WHERE departure_date > '2022-04-12' AND return_date < '2022-05-01');, but how it can be done using django ORM without raw queries? -
Django with Javascript form not returning to View
I am trying to learn Javascript by developing an interactive form in Django. The form presents a Select list that allows multiple selections. As one or more tests in the list are selected the Javascript updates a list on the page with the current selections. When I press Submit, I expect to return to the View but instead I get a 405 Error and am not directed to the success URL. I added a Print statement to the form_valid method in the View and it never executes. Not sure how to get where I want to go. views.py class OrderTestsViewForJS(ListView): model = Universal_Test_File context_object_name = "testlist" success_url = '/list-patient/' template_name = "lab/order_tests_js.html" def get_context_data(self, *args, **kwargs): patient = get_object_or_404(Patient, pk=self.kwargs['pk']) context = super(OrderTestsViewForJS, self).get_context_data(**kwargs) context['patient'] = patient return context def form_valid(self, form): print("in form valid") return super().form_valid(form) stripped down template.html {% extends 'base.html' %} {% block title %}Order Tests{% endblock title %} {%load static%} {% block content %} <div class="card mt-5 "> <div class="card-header text-center"> NovaDev Order Tests Module </div> <div class="card-body"> <div class="row"> <div class="col-3 m-5"> <form action="" method="post"> {% csrf_token %} <select id="select_tests" name="select_tests" multiple > {% for test in testlist %} <option value = "{{test.service_id}}" > {{test.test_name}}</option> … -

How does discord manages roles and permissions in database?
Users can have multiple roles, roles have multiple permissions, and roles are protected by servers. I was wondering do they use relational db for that? Is django capable of doing such thing? Because to fetch each user for server with role will be very expensive. Does discord uses django for this or any other framework? Any thoughts please? I am trying to build a similar schema but I think it will be very expensive for the db transactions and queries. I have workspace, workspace have users, users have multiple roles, roles have multiple permissions(groups in djangos). And I think this will be very expensive to call a single user to check whether he belongs to this group or not. -

What is equivalent to TestCase.client in normal script
