KnowMore

This gem aims to provide a general questionnaire scaffold, with which you can quickly make you own questionnaire page.

This is a Rails-based gem. It can only work with you Rails application. Add this line to your application's Gemfile:

gem 'know_more'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install know_more

How to use KnowMore to generate questionnaire scaffold to you?

rails g know_more:init

This will generate a initializer file, where you can config the questionnaire steps and the url to go when questionnaire is finished

Configure the the initializer file config/initializers/know\_more.rb

Then run the install generator, which will give you templates, controller concerns, model and migration file.

rails g know_more:install MODEL

This will generate template with erb engine, you can use --haml to generate haml template

The argument MODEL indicates the questionnaire model name

It will also create a migration, you can add other attribute to this migration

1. app/controllers/concerns/know_more/questionnaire_controller_concerns.rb

   This file is included by the QuestionnaireController(in the gem), you can add the behaviour that you want to do in each step

   Here is an example:

   module KnowMore
     # this module is used to define the functions
     # that will actually run in the KnowMore/QuestionnaireController
     module QuestionnaireControllerConcerns
       def self.included(base)
         # define the behaviour when included
         base.before_action :set_questionnaire
       end
   
       # _stepN function will be called by questionnaire#stepN
   
       def _step1
       end
   
       def _step1_update
         @questionnaire.update(questionnaire_params)
       end
   
       def _step2
       end
   
       def _step2_update
         @questionnaire.update(questionnaire_params)
       end
   
       private
       def set_questionnaire
         @questionnaire = current_questionnaire
       end
   
       def questionnaire_params
         params.require(:questionnaire).permit(:attribute1, :attribute2, :attribute3)
       end
     end
   end

2. app/models/MODEL.rb This is the questionnaire model, it has an attribute progress which records which step the client was on. Cooperating with require_questionnaire!, you can force your client to continue with the previous questionnaire.

Then include the module KnowMore::ControllerHelpers into your ApplicationController or BaseController and implement your own current_questionnaire

class ApplicationController < ActionController::Base
  include KnowMore::ControllerHelpers

  def current_questionnaire
    # your implementation
  end
end

1. The questionnaire returned by current_questionnaire should be created at first. Because the process of doing questionnaire is only editing

2. In the KnowMore::ControllerHelpers, it provide a helper function require_questionnaire!, it could force user to finish questionnaire before going to a controller by redirecting the user to the last step of the questionnaire

before_action :require_questionnaire!

1. add welcome page configuration
2. allow copy the controller to user app so that user can modify the questionnaire controller
3. support rename step
