Wicked, after delete action redirect_to - ruby-on-rails

Question

I have used wicked gem for my form. The thing is when user uploads photo they can see at the same page as ..../steps/picture. At Picture page user can destroy the picture. When user clicks I would like them to redirect_to steps/picture page but whatever I tried I get error on that. Boat and Picture associated but not nested routes.
here is my picture controller #destroy action;
def destroy
#picture = #boat.pictures.find(params[:id])
if #picture.destroy
######SOMETHING GOES HERE#########
flash[:notice] = "Successfully destroyed picture."
else
render json: { message: #picture.errors.full_messages.join(',') }
end
end
#boat_steps controller;
class BoatStepsController < ApplicationController
include Wicked::Wizard
before_action :logged_in_user
steps :model, :pricing, :description, :features, :picture
def show
#boat = current_user.boats.last
case step
when :picture
#picture = #boat.pictures.new
#pictures = #boat.pictures.all
end
render_wizard
end
def update
#boat = current_user.boats.last
#boat.update(boat_params)
case step
when :picture
#picture.update(picture_params)
end
render_wizard #boat
end
private
def finish_wizard_path
new_boat_picture_path(#boat, #picture)
end
def boat_params
params.require(:boat).permit(......)
end
def picture_params
params.require(:picture).permit(......)
end
end

On wicked wizards there are path helpers available on views that don't show on rake routes.
Try redirect_to wizard_path(:picture)
You can find more information about wicked helpers available to views here: https://github.com/schneems/wicked#quick-reference
These helpers will be available on views rendered using render_wizard. Outside of the wizard, the step is passed as the :id of the RESTful route.
To redirect to boat_steps/show on the picture step try redirect_to boat_step_path(id: :picture). The url generated should be /boat_steps/picture.
