Hstore Attributes

If you want PostgreSQL's Hstore attributes to be validated by Reform's form object, you can follow these example settings.

Model:

# app/models/profile.rb
class Profile < ActiveRecord::Base
  # name is a normal column
  # info is a hstore column
  store_accessor :info, :occupation, :academic_subject, :educational_institutions, :address
  # rest of the codes ....
end

Form Object:

## app/forms/profile_form.rb
class ProfileForm < Reform::Form
  properties [:name, :occupation, :academic_subject, :educational_institutions, :address]

  validates :name,                     presence: true, length: { within: 3..50 }
  validates :occupation,               length: { maximum: 50 }
  validates :academic_subject,         length: { maximum: 50 }
  validates :educational_institutions, length: { maximum: 50 }
  validates :address,                  length: { maximum: 50 }
end

Controllers:

# app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  def process_form(form, params)
    if form.validate(params)
      form.save do |data, map|
        yield data, map
      end
    else
      render json: form.errors, status: :unprocessable_entity
    end
  end
end

# app/controllers/profiles_controller.rb
class ProfilesController < ApplicationController
  respond_to :html, :js

  def new
    @form = ProfileForm.new(Profile.new)
  end

  def create
    @form = ProfileForm.new(Profile.new)
    process_form(@form, params[:profile]) do |data, map|
      profile = current_user.create_profile(map)
      profile.save
      respond_with profile
    end
  end
end

Form View:

# app/views/profiles/new.html.haml
= form_for @form, data: { remote: true } do |f|
  = f.text_field :name
  = f.text_field :occupation
  = f.text_field :academic_subject
  = f.text_field :educational_institutions
  = f.text_field :address

  = f.submit
