render_wizard
end
def update
#user = current_user
if #user.save

I think there is some mistakes in your conception.
The wizard operates AFTER the sign_up of your user.
So basically, you need to create your user first without the wizard.
Creation of your User
If you're using Devise with your model User, you already have a User Controller somewhere. Actually, your class UsersController is useless if you are using Devise.
So if you want to redirect to your wizard step after the sign up, then you need to override the Devise registration controller (doc: Redirect to specific page).
To do so, create a new controller like this:
class RegistrationsController < Devise::RegistrationsController
protected
def after_sign_up_path_for(resource)
user_steps_path(:finishing_step) #add proper route
end
end
I don't have the content of your config/route.rb file but you need to have something like this :
resources :user_steps
Adding steps
Wicked wizard works like this:
- One controller with 2 actions (show and update)
- N views for N steps (1 step = 1 view, 42 steps = 42 views)
You can access the name of your current step in the actions show and update using step.
render_wizard render the view of the current step
render_wizard #user render the next step view (or the current step view if there is any error)
Using strong parameters
In your controller, you never use user_params.
So in your update action, you never the your #user with the parameters from your form. current_user doesn't call user_params for you.
Also, there is a big difference between save and update_attributes and I think you want to use the second in your update action.
It's better to place user_params in the private section also.
Final form of your controller
Your controller should look like that I guess:
class UserStepsController < ApplicationController
include Wicked::Wizard
steps :finishing_step
def show
#user = current_user
render_wizard
end
def update
#user = current_user
if #user.update_attributes(user_params)
# because you only have one step, you don't need render_wizard #user
redirect_to_finish_wizard
else
render_wizard
end
end
private
def user_params
params.require(:user).permit(:first_name, :middle_name, :last_name, :address_first_line, :address_second_line, :city, :nationality)
end
def redirect_to_finish_wizard
redirect_to root_path, notice: "Thanks for signing up."
end
end
Read the doc
I think you miss some tips in the wicked doc.
Maybe you should re-read it.
