How can I correctly send the status of a checkbox to Django using hx-vals? I attempted the following method:

hx-vals='{
"solved":  "document.querySelector("input[name="solved"]").checked",
"comment":  "document.querySelector("input[name="comment"]").checked",
"no_solution":  "document.querySelector("input[name="no_solution"]").checked",
}'

In the Django views, I expected to retrieve the values like this:

filter_solved = request.GET.get("solved") == 'true'

However, I couldn’t make this work. How can I fix this?
Ty!!!
