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

Question

So I have a User model generated with devise, and I am using Wicked gem to give me multiform option on taking more data from the user and storing it in the user model.
Everything is working fine but know I'm trying to add another model where user has many degree. I am using cocoon gem to allow me to add extra degrees. I am able to go to the multiform page and enter degree information and even add many more degrees to the user, but when i submit the form i get an error;
param is missing or the value is empty: user
Everything else actually gets saved am i can view the user and the rest of the fields entered but non of the 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 is the 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]
# GET /resource/sign_up
def new
super
end
# POST /resource
def create
super
end
# PUT /resource
def update
super
end
protected
# The path used after sign up.
def after_sign_up_path_for(resource)
user_steps_path
end
# The path used after sign up for 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 an error in the user_steps_controller:
ActionController::ParameterMissing in UserStepsController#update
param is missing or the value is empty: user
and that the error is within this 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 would i go and view the entered fields, for example if i wanted to view user name it is:
<%= #user.name %>
but how would i show each degree? is it just a loop?
<% #users.degree.each do |degree| %>

This is too long to comment, I fully expect to update it.
The problem you have is that your form submission does not include any user params:
Parameters: {"utf8"=>"✓", "authenticity_token"=>"EXN7ts6xPVK8vkC7q6UcNleJJWLUtKmOw41T0qsDqXCrPJ0vIHrB/6xIfpp/o+cXKR47F+6LxUY5LjXlCobKZQ==", "commit"=>"Update User", "id"=>"education"}
This might be Wicked, but judging form your spurious use of RegistrationsController, I'd imagine it could be to do with formatting etc:
--
If you're updating your current_user, you should not be invoking your registrations controller. That is for registrations -- you should be using your 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 is just the controller; you need to look at how the form is being rendered & passed.
If you're sending data with the above code, you'll want to pull your form HTML and show how Wicked is working with it.
You need to be looking in app/views/users/show.html.erb for the form to display, not /app/views/registrations
