ruby on rails - Rails4 Entering data from one controller to multiple models -

i have of unique problem. have 3 tables in database need populate data. tables in relation each other. first table's info static , populated hash. second table table targeted data.

i having tough time trying add data second table using strong parameters. error param missing or value empty: entries

modles:

client.rb

class client < activerecord::base   has_many :entries  end 

entry.rb

class entry < activerecord::base   belongs_to :client_name   has_many :extra_data   end 

extra_data.rb

class extradata < activerecord::base   belongs_to :entries end   class clientscontroller < applicationcontroller    before_action :set_client, only: [:show, :update, :destroy, :edit]    # submit intended purposes.   #   def new     @entries = entry.new()   end    def create     @client = client.new(cleint_attr)      if @client.save       @entries = entry.new(submit_params)        redirect_to action: :index      else        flash.alert "you failed @ life today."         redirect_to action: :index     end   end    .   .   .    private    def submit_params     params.require(:entries).permit( :full_name,:email,:opt_in )   end    def set_client     @client = client.find(params[:id])   end  end 

form

<%= simple_form_for(:client, url: {:controller => 'clients', :action => 'create'}) |f| %>   <%= f.input :full_name %>   <%= f.input :email %>   <%= f.input :opt_in %>    <%= f.button :submit, class: "btn-primary" %> <% end %> 

routes:

rails.application.routes.draw    resources :clients     resources :entries       resources :extra_data     end   end    root 'clients#index' end 

in database client data goes in out problem. having problem getting data form itself.

this answer culmination of few different parts.

i figured out not saving data model. needed make if statement.

def create   @client = client.new(cleint_attr)   if @client.save     @entries = entry.new(submit_params)     if @entries.save       flash[:alert] = "failure! working."       redirect_to action: :index     else       flash[:alert] =  "success! @ failing."     end    else      flash[:alert] =  "you failed @ life today."       redirect_to action: :thanks   end end 

also changing form :entries helped. had typo in permit statment. had :opt_in when needed use :optin @tmc
