Setting Foreign key params Relationship in rails - ruby-on-rails

Question

I've searched a lot , found similar questions , but any seem to fit , or i did not understood right.
i have 3 models , i choose a bad name for one model, that is for Tv Shows , and you may confuse the Show model with show method and view .
Show.rb
class Show < ActiveRecord::Base
has_many :seasons
belongs_to :user
has_many :episodes , through: :seasons
accepts_nested_attributes_for :seasons
attr_accessible :name,:status,:duration
end
Season.rb
class Season < ActiveRecord::Base
belongs_to :show
has_many :episodes
accepts_nested_attributes_for :episodes
attr_accessible :order,:status
end
Episode.rb
class Episode < ActiveRecord::Base
belongs_to :season
attr_accessible :number
end
My forms for each model are separeted, what i wanna do is set the foreigns keys for each one automatically. So , in the view of my Show i wanna create a season that will be stored in that Show.
Shows/show.html.erb
p id="notice"><%= notice %></p>
<% #seasons = Season.all %>
<% #episodes= Episode.all%>
<p>
<strong>Name:</strong>
<%= #show.name %>
</p>
<p>
<strong>Status:</strong>
<%= #show.status %>
</p>
<p>
<strong>Episode Duration:</strong>
<%= #show.Episode_Duration %>
</p>
<% #seasons.where(:show_id => #show.id).each do |season| %>
<tr>
<td><%= season.order %></td>
<td><%= season.status %></td>
<h3>episodios</h3>
<hr>
<% #episodes.where(:season_id => season.id).each do |episode| %>
<td> <%= episode.number%></td>
<%end%>
<hr>
<td><%= link_to 'episode', episode_new_path(season.id)%></td>
</tr>
<br>
<% end %>
<h1><%=#show.id%></h1>
<h1><%=#show.episodes.count%></h1>
<h1></h1>
**<%= link_to 'create seasons', season_new_path(#show.id) %>**
<%= link_to 'Edit', edit_show_path(#show) %> |
<%= link_to 'Back', shows_path %>
In that lasts line, i'm passing #show.id for create a season, i want use that #show.id as my foreign key :show_id for that season. how i use that id in my params?
I saw some posts and i tried this , but didn't worked , heres the controller(only the part that i think is useful.)
seasons_controller.rb
def create
#season = Season.new(season_params)
#season.show_id = params[:id]
#season.save
end
respond_to do |format|
if #season.save
format.html { redirect_to #season, notice: 'Season was successfully created.' }
format.json { render :show, status: :created, location: #season }
else
format.html { render :new }
format.json { render json: #season.errors, status: :unprocessable_entity }
end
end
def season_params
params.require(:season).permit(:order, :status)
end
EDIT
My routes are:
Routes.rb
devise_for :users
resources :episodes
resources :seasons
resources :shows
root 'shows#index'
get 'seasons/create/:id' => 'seasons#new', as: :season_new
get 'episodes/create/:id' => 'episodes#new', as: :episode_new
put 'subscribe_show/:id' => 'shows#subscribe', as: :user_subscribe_show
put 'unsubscribe_show/:id' => 'shows#unsubscribe', as: :user_unsubscribe_show
get 'user/dashboard/' => 'users#index', as: :user_dashboard
And my forms are:
seasons/form.html.erb
<%= form_for(#season) do |f| %>
<% if #season.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#season.errors.count, "error") %> prohibited this season from being saved:</h2>
<ul>
<% #season.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :order %><br>
<%= f.number_field :order %>
</div>
<div class="field">
<%= f.label :status %><br>
<%= f.text_field :status %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Show/form.html.erb
<%= form_for(#show) do |f| %>
<% if #show.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#show.errors.count, "error") %> prohibited this show from being saved:</h2>
<ul>
<% #show.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %><br>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :status %><br>
<%= f.text_field :status %>
</div>
<div class="field">
<%= f.label :Episode_Duration %><br>
<%= f.text_field :Episode_Duration %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
EDIT 2:
schema.rb
create_table "episodes", force: :cascade do |t|
t.integer "number"
t.integer "season_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
create_table "seasons", force: :cascade do |t|
t.integer "order"
t.string "status"
t.integer "show_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.boolean "watched"
end
create_table "shows", force: :cascade do |t|
t.string "name"
t.string "status"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "Episode_Duration"
t.integer "user_id"
end
Migrations
class AddUserIdtoShow < ActiveRecord::Migration
