lucky to get the correct param value when work with htmx + checkbox and return two same name attribute's value.

[zw963]

When worked with builtin checkbox method + a model column, lucky will generate a hidden input element which use same name attribute value, like following:

<form>
  <input type="hidden" name="university:chong_2023" value="false">
  <input type="checkbox" id="chong_2023" name="university:chong_2023" value="true" hx-put="/universities/843"
</form>

it work as expected.

When when work with htmx which not a form, like this:

label do
            input(type: "hidden", name: "university:is_marked", value: "false", id: "marked_unmark")
            input(
              type: "checkbox",
              name: "university:is_marked",
              value: "true",
              id: "marked",
              "hx-put": "",
              "hx-target": "",
              "hx-swap": "outerHTML",
              "hx-indicator": "#spinner",
              "hx-include": "[name='_csrf'],[name='university:is_marked']"
            )
            span "手动"
          end

I get following params.body when checkbox checked

web          | params.body # => "university%3Ais_marked=true&university%3Ais_marked=false"

And get following when unchecked

web          | params.body # => "university%3Ais_marked=false"

The issue is, on both cases, params.to_h always return false, like following

web          | params.to_h # => {"university" => {"is_marked" => "false"},
web          |  "_csrf" => "UzxOfKACL6XbS0PZn10tih4Tg0eEVjD6oPdMJBBVRo0"} 

my question is, how to get the true value of is_marked when request.body is "university%3Ais_marked=true&university%3Ais_marked=false"?

Thanks.

It's seem like only params.get_raw(:"university:is_marked") get the expected result.

Checking following log:

# check the checkbox

web          | params.nested(:university) # => {"is_marked" => "false"}
web          | params.to_h # => {"university" => {"is_marked" => "false"},
web          |  "_csrf" => "UzxOfKACL6XbS0PZn10tih4Tg0eEVjD6oPdMJBBVRo0"}
web          | params.body # => "university%3Ais_marked=true&university%3Ais_marked=false&_csrf=UzxOfKACL6XbS0PZn10tih4Tg0eEVjD6oPdMJBBVRo0"
web          | params.get_raw(:"university:is_marked") # => "true"
web          |  ▸ Sent 200 OK (8.1ms)

uncheck the checkbox

web          | PUT /htmx/v1/universities/843/marked
web          |  ▸ Handled by Universities::Htmx::Marked
web          | params.nested(:university) # => {"is_marked" => "false"}
web          | params.to_h # => {"_csrf" => "UzxOfKACL6XbS0PZn10tih4Tg0eEVjD6oPdMJBBVRo0",
web          |  "university" => {"is_marked" => "false"}}
web          |
web          | params.body # => "_csrf=UzxOfKACL6XbS0PZn10tih4Tg0eEVjD6oPdMJBBVRo0&university%3Ais_marked=false"
web          | params.get_raw(:"university:is_marked") # => "false"
web          |  ▸ Sent 200 OK (6.71ms)

Because params.nested(:university) always return false in both cases, so, following code not work correct:

SaveChongWenBao.update!(chong_wen_bao, params)

I have to use like following:

SaveChongWenBao.update!(chong_wen_bao, is_marked: params.get_raw(:"university:is_marked") == "true" ? true : false)

So, i consider this as a bug, what do you think?

It looks like it could be a bug.
