Eine allgemeine Liste der gebuchten Benutzer anzeigen

Question

Ich habe eine Anwendung erstellt, wo Benutzer eine Stunde Training buchen können. Ich möchte Admin-Benutzern die Möglichkeit geben, eine allgemeine Liste der gebuchten Benutzer in jeder Trainingsstunde zu sehen.

Im Versuch, diesen Index zu schaffen, aber es gibt mir die folgende Fehlermeldung:

ActionController::UrlGenerationError in Trainings#index

No route matches {:action=>"index", :controller=>"bookings", :training_id=>nil} missing required keys: [:training_id]

Im Versuch, diese Schaltfläche am Index der Ausbildung zu schaffen, wie folgt aus:

Ausbildung index.html.erb Ausblick:

<h1>Hours</h1> 

<ul class="trainings"> 
    <% @trainings.each do |training| %> 
    <li> 
    <%= link_to training.hour, training_path(training) %> 
    </li> 
    <% end %> 
</ul> 

<%= render 'bookings/general_list' if logged_in? %> 

_general_list.html.erb Ansicht:

<ul class="bookings"> 
<% @trainings.each do |training| %> 
<%= link_to "General list", training_bookings_path(@training), class: "btn btn-primary" %>  
<% end %> 
</ul> 

Ich möchte jetzt, wie ich das schaffen kann, denke ich, dass meine Idee nicht funktioniert.

mein routes.rb:

Rails.application.routes.draw do 

    root 'static_pages#home' 
    get '/signup',    to: 'users#new' 
    get '/contact',    to: 'static_pages#contact' 
    get '/about',    to: 'static_pages#about' 
    get '/login',    to: 'sessions#new' 
    post '/login',    to: 'sessions#create' 
    delete '/logout',    to: 'sessions#destroy' 


    resources :account_activations, only: [:edit] 
    resources :password_resets,  only: [:new, :create, :edit, :update] 
    resources :users 
    resources :trainings do 
    resources :bookings 
    end 
end 

Rake Routen Befehl:

    Prefix Verb URI Pattern           Controller#Action 
        root GET /             static_pages#home

In _general_list.html.erb sollten Sie @training für training
