Formbuilder.rb

Formbuilder.rb is a Rails Engine that's designed as a compliment to Formbuilder.js, a library that lets your users create their own webforms inside of your application.

Since Formbuilder.rb is a fairly non-trial piece of software, it's important to understand its components and how it works:

1. We add ResponseField, EntryAttachment, and Form models to your application. (Each type of response field (text, checkboxes, dropdown, etc.) uses STI, inheriting from the ResponseField model.)
2. You include Formbuilder::Entry in an existing model.
3. We add a few classes to help you render forms and entries.

Note: All Formbuilder models and classes are namespaced within the Formbuilder module.

If you have a few moments, consider reading the source, especially the Rails app in spec/dummy, as it should give you a good idea of how Formbuilder integrates.

Postgres is currently required. See Issue #1.

Carrierwave and Rmagick for file uploads. Geocoder to geocode address fields.

gem 'formbuilder-rb', require: 'formbuilder'

1. rake formbuilder:install:migrations
2. rake db:migrate

#  responses       :hstore
#  responses_text  :text

class Entry < ActiveRecord::Base
  include Formbuilder::Entry
end

class MovieTheater < ActiveRecord::Base
  has_one :form, as: :formable, class_name: 'Formbuilder::Form'
end

<%= Formbuilder::FormRenderer.new(@form, @entry).to_html %>

@entry = Entry.new(form: @form)
@entry.save_responses(params[:response_fields], @form.response_fields) # validates automatically

@entry.valid?
# => false

@entry.error_for(form.response_fields.first)
# => "can't be blank"

# config/routes.rb
resources :forms, only: [:update]

# app/controllers/forms_controller.rb
class FormsController < ApplicationController
  include Formbuilder::Concerns::FormsController
end
