ruby on rails - Creating form for STI Model -

referring post: rails: deal several similar model classes?

using combination of sti , store feature organize similar models.

"declare base model student text column called settings.

class student < activerecord::base   store :settings   # name, email, phone, address etc.. end  class highschoolstudent < student   # declare highschoolstudent specific attributes    store_accessor :settings, :gpa end 

how can create form highschoolstudent, while remaining under student controller?

i dont want add separate controller or route resource highschoolstudent, there way have 1 form student , highschoolstudent, checkbox indicate whether student or highschoolstudent? can require attributes created subclass required form submitted if specific class checked?

<%= simple_form_for(@student, html: {class: "form-horizontal"}) |f| %> 

<%= f.input :name, as: :text, input_html: {rows: "1"} %> <%= f.input :email, as: :text, input_html: {rows: "2"} %>  <%= f.input :gpa, as: :text, input_html: {rows: "1"} %>   <%= f.button :submit, class: "btn btn-primary" %> 

sure, can make arbitrary checkbox, , check value in create action:

# in view <%= check_box_tag :high_school %>  # in controller def create   base_class = params[:high_school] ? highschoolstudent : student   base_class.create(params[:student])   ... end 

any validations specific highschoolstudent ensured if checkbox checked.
