Is there possible to not use param_key when create a form use a Save Operation object?

[zw963]

following is a example for describe my issue:

class Pages::New < BrowserAction
  get "/pages/new" do
    html Pages::NewPage, operation: SavePage.new
  end
end

Then create a form in the pages

form_for Pages::Create do
    mount Shared::Field, attribute: op.title, label_text: "标题", &.text_input(autofocus: "true")
end

I don't want the param always be nested in this case, like: "page:title", what I expected is, "title", how to do that?

use param_key: "" like following not work as expected.

class SavePage < Page::SaveOperation
  param_key ""

  permit_columns title, sub_title, markdown_path, content, parent_markdown_path
end

the form data name prefix with a :, like this: :title

Thanks

Not at the moment. The param_key is currently required.

I consider make this required is not necessary, because of this limit, I actually rarely use form_for.

for my use case, because my form is used for create a markdown, so, I need to save markdown for one of the column, and preview markdown on different form use same markdown preview action, there is no common prefix when save on different tables.

current, I can workaround like this:

1. use non-prefix column name for markdown in the page.

mount Shared::Field, attribute: op.content, label_text: "内容", &.textarea(rows: 8, cols: 60, name: "content")

2. merge the value of content column when create.

SavePage.create(params, content: params.get(:content)) do |operation, page|
   # ...
end

If we can set the param_key to blank to permit the non-prefix form, actually we can simple this solution, and no any lose.
