ruby on rails - Wicked Gem with cocoon gem and devise user model -

so have user model generated devise, , using wicked gem give me multiform option on taking more data user , storing in user model.

everything working fine know i'm trying add model user has many degree. using cocoon gem allow me add degrees. able go multiform page , enter degree information , add many more degrees user, when submit form error;

param missing or value empty: user 

everything else gets saved can view user , rest of fields entered non of degrees.

user model:

has_many :degrees accepts_nested_attributes_for :degrees, reject_if: :all_blank, allow_destroy: true 

degree model:

belongs_to :user 

user_steps_controller (this wicked gem controller):

class userstepscontroller < applicationcontroller    include wicked::wizard   steps :personal, :avatar_and_about_yourself, :social, :education    def show     @user = current_user     render_wizard   end    def update     @user = current_user     @user.update_attributes(user_params)     render_wizard @user   end    private    def user_params     params.require(:user).permit(:name, :middlename, :lastname, :avatar, :aboutme, :twitterlink, :githublink, :stackoverflowlink, :mediumlink, :dribblerlink, degrees_attributes: [:id, :degreename, :university, :level, :done, :_destroy])   end  end 

registration controller (for devise):

class users::registrationscontroller < devise::registrationscontroller # before_filter :configure_sign_up_params, only: [:create] # before_filter :configure_account_update_params, only: [:update]    # /resource/sign_up    def new      super    end    # post /resource    def create      super    end    # put /resource    def update      super    end     protected    # path used after sign up.    def after_sign_up_path_for(resource)      user_steps_path    end    # path used after sign inactive accounts.    def after_inactive_sign_up_path_for(resource)      user_steps_path    end     def sign_up_params      params.require(:user).permit(:email, :password, :password_confirmation, :name, :middlename, :lastname, :avatar, :aboutme, :twitterlink, :githublink, :stackoverflowlink, :mediumlink, :dribblerlink, degrees_attributes: [:id, :degreename, :university, :level, :done, :_destroy])    end end 

im getting error in user_steps_controller:

actioncontroller::parametermissing in userstepscontroller#update param missing or value empty: user 

and error within line:

 def user_params     params.require(:user).permit(:name, :middlename, :lastname, :avatar, :aboutme, :twitterlink, :githublink, :stackoverflowlink, :mediumlink, :dribblerlink, degrees_attributes: [:id, :degreename, :university, :level, :done, :_destroy])   end 

also how go , view entered fields, example if wanted view user name is:

<%= @user.name %> 

but how show each degree? loop?

<% @users.degree.each |degree| %>

this long comment, expect update it.

the problem have form submission not include user params:

parameters: {"utf8"=>"✓", "authenticity_token"=>"exn7ts6xpvk8vkc7q6ucnlejjwlutkmow41t0qsdqxcrpj0vihrb/6xifpp/o+cxkr47f+6lxuy5ljxlcobkzq==", "commit"=>"update user", "id"=>"education"} 

this might wicked, judging form spurious use of registrationscontroller, i'd imagine formatting etc:

--

if you're updating current_user, should not invoking registrations controller. registrations -- should using users controller:

#config/routes.rb resource :user_steps, path: "user", only: [:show, :update] #-> url.com/user (singular resource)  #app/controllers/user_steps_controller.rb class userstepscontroller < applicationcontroller   def show   end    def update     @user = current_user.update user_params     render_wizard @user   end    private    def user_params     params.require(:user).permit(:name, :middlename, :lastname, :avatar, :aboutme, :twitterlink, :githublink, :stackoverflowlink, :mediumlink, :dribblerlink, degrees_attributes: [:id, :degreename, :university, :level, :done, :_destroy])   end end 

this controller; need @ how form being rendered & passed.

if you're sending data above code, you'll want pull form html , show how wicked working it.

you need looking in app/views/users/show.html.erb form display, not /app/views/registrations
