Passing Data to Next Step in a Wicked Wizard

I just watched the Railscast on the Wicked gem used to create multi step wizards.

I was wondering if this gem could be used to create a wizard where data is passed forward somehow in the render_wizard call? Based on my initial tinkering, I do not believe that this is possible. The problem I hope to solve is to create a wizard where the first step takes a country and the second step allows the selection of people from that country.

Is there any easier way to solve this problem? Thanks for the help!

ya you can pass data to the next step through the render method

render_wizard(@user, {}, { hello: 'world', your_param_key: "param value" })

here the params are

params[:hello] == "world"

params[:your_param_key] == "param value"

hope that helps anyone else in the future :)

You could employ a table-less ruby object. Serialize it to the session before each show step and load it up from the session (merging in any new params) before each update step.

before_filter :initialize_wizard, on: [:show, :update]

...

def initialize_wizard
  @wizard = YourWizardTempModel.new
  @wizard.update_attributes(session['wizard']) if session['wizard'].present?
  @wizard.update_attributes(params['wizard']) if params['wizard'].present?
  session['wizard'] = @wizard.as_json
end

Then you could have a conditional before_filter that assembled the people selection based on the country_id like such:

before_filter :populate_people, if: "step == 'select_people'"

...

def populate_people
  People.find_by_country_id(@wizard.country_id)
end
