filter_form | Build filter forms easily dart | Validation library

I have created the below class in attempt to keep Form class "clean" as in not much working out there and mainly just references to other classes which do the work. It worked when the code was within the Form class as I believe the binding in XAML simlpy bound to the MainList, TypeList etc. ObservableCollection and I thought if I create an instance of the CheckedBoxLists class it will still find those objects and display data from them but I guess that is not how it works.

My Wagtail project is at heart just a very conventional listings page where users can browse items in the database and then click on any item of interest to go its detail page. But how do I allow users to filter and/or sort the listings on the main page by the contents of fields on the child pages? This most generic, ordinary task eludes me.

Let's say the database is a collection of Things. And let's say that what people find important about each Thing are (a) the year it was discovered, and (b) the country where it can be found. A user may want to browse through all the Things, but she should be able to narrow down the list to just those Things found in 2019 in Lithuania. And she should be able to sort by year or by country. Just your super-standard functionality but I can't find any guidance or figure it out myself.

Cribbing from examples of other people's work here are my models so far:

I applied django-filter library in my project if it's not filtering the items. if i visit the url http://127.0.0.1:8000/products/?q=&category=electronics it should gives the only electronics products but its giving the all available products. What i am doing wrong? it should filter categories wise or product title wiase and price wise.

I wrote a basic toggle function that I have used before but for some reason it is not entirely working. The reason I say that is because when I console log the display it says the display is none but the element never disappears. I know for a fact that the function is firing and that it detects the elements display as "", however it sets it to none (and logging that to the console proves it) but the actual element does not disappear from the screen.

How can we get to work the moodle filters when UNION is come up in an SQL query. The below code shows the filter form where filters aren't working. The code works when UNION is not used.

I've a small Django project basic-pagination. There is one model, one form and two views (list view, form view). User submits data in the form view, then the data is displayed in the list view. Pagination is enabled to only display 5 posts at a time.

What I've implemented is a form with a GET response to get the data I want to display (e.g. name, date). See code below

Hi i'm trying to make a validation on my form and change the values that send through form if a collapse element(of that value) = False to a null value (i'm still kinda new to javascript and Jquery).

I have 3 buttons that should change the behavior of the videos on the page depending on the chosen dropdowns. But the user chooses a choice from the dropdown, the videos don't cooperate.

This is the front end. When I choose something on for example language, the videos should change, but it doesn't.

The page ends up on http://localhost:8000/?language=EN&level=LEV&category=CAT then the page breaks

I tried adding a reverse_url on the views but it still didn't fix the error.

I'm trying to make a filter using a MySQL database and PHP for a school project, but whenever I press my filter button, it doesn't execute the action so the querystring is not updated.

The reason it's referring to my homepage is because of this block code:
