filterable | Bootstrap themed per-column filter | Grid library

I wanna do a simple recommendation system based on users' Animals that they added. I want to show only products of a category, that's been mapped in "zwierzeta" dictionary. So basically if user has chosen that he has a horse (which is id 1, i want to show only products that have category 4) Also if user has more than 1 animals, i want to show them randomly from list of categories id. The logic seems to be fine, im just new at django and i have no idea how to actually iterate through the querysets and how to get a value(animal) from a particular queryset. The get method doesnt work. Do you have any idea how to get a particular value from a queryset?

My api in c# send all the employees informations from the database to my web app (angular).

I want to don't print in (angular) the employees whose id begins with '#'.

Employee = Collaborateur

Here is my angular service which calls my api to retrieve the information :

I'd like to store a reference to a class in state but an error occurs.

Specifically, the following:

I am working an a Blazor page where I want to make use of Radzens DataGrid. I used the example of the DataGrid Inline Editing for editing and adding contacts of my database. And the structure overall.
This works totally fine.

I populate my list of contacts from the database within:

I have a Kendo grid with hyperlink to cell values as below,

on clicking the hyperlink it routes to different page, based on different scenarios

I've a database structure built with JPA. To give a little bit context - the user is shown a datatable and some (many...) filters with which he can filter the shown entries of the datatable. For example, every entry of the datatable corresponds to a certain factory (of e.g. 40 factories in total) and the user can filter for one or more factories.

To prevent overhead, the user can only filter by factories which occur in the dataset the datatable is built of, i.e. factories which would give an empty result after filtering (since there aren't any entries with this factory) aren't shown at all in the factory filter.

Furthermore, the datatable is paginated, i.e. just the first (second, third, etc.) 50 entries are given to the frontend but -- and that's the crucial point -- the filters should of course correspond to all entries (i.p. also the entries on the pages which are not shown). That means if factory B only occurs on page 2 and page 1 is loaded (i.e. there is no factory B under the shown entries resp. the entries the frontend receives), the factory filter should still list factory B.

My approach is the following: When constructing the result, using the same sql query, I get all values which one can filter by. So my constructed table looks so to say like this

The code below produces the following table:

The Goal is to be able to select a category in the Manufacturer column (ex/ Buick) and have the 4 Models (2 from Midsize and 2 from Large) get selected. Right now the Select All feature only works by Models grouped by Type.

What I tried: ActionButton and observeEvent with updateReactable("table", selected = ...) The issue is that I want to give the users the ability to select all Models from multiple Manufacturer categories (ex/ The user selects all rows under Acura AND all rows under Buick). The action button I had tried only worked for one category and the table re-set if another button was clicked. Happy to include this failed code if it helps.

I'm staring to integrate my project with vuetify i'm trying to crate a table following the tutorial https://vuetifyjs.com/en/getting-started/installation/#usage-with-cdn and https://vuetifyjs.com/en/components/data-tables/#usage but I can't make it work here the code of index.cshtml

I found the code of a beautiful gallery (HTML, CSS, javascript).

Responsive Filterable Image Gallery is used on my website to display by category.

However, only one image selected only one category.

How can I change this code, and one image can be displayed in 2-3 categories?
