SimpleForm without for (non model form)

Question

Is it possible to use Simple Form (by: Plataformatec) without a model?

All of the methods above still leave you with form data nested inside of "user" or whatever symbol that you pass as the first argument. That's annoying.

To mimic simple_form's style/benefits, but remove the object/symbol dependency and the forced data nesting, you can create a partial.

HAML examples:

form view:

= form_tag("path/to/action", method: "POST") do
    = render "path/to/partial/field", type: "string", required: true, item: "first_name"

field partial:

- required_string = required ? "required" : ""
%div{class: "input #{type} #{required_string} #{item}"}
  %label{class: "#{type} #{required_string}", for: "#{item}"}
    - if required
      %abbr{title: "required"}
        *
    = t("application.#{item}")
  %input{name: "#{item}",                                                     |
    placeholder: t("application.#{item}"),                                    |
    type: "#{type}",                                                          |
    required: required,                                                       |
    "aria-required" => "#{required}" }
