Rails 4.1.4 ActionController param is missing or the value is empty: name - strong-parameters

Question

I am relatively new to learning how to code and I am really having problems understanding how to write the code for dealing with parameters in a private method in the controller of a Rails 4.1.4 app so that my app works correctly by allowing me to enter a new picture album name, save it to the db, and have it be persisted so that the name of the new album added shows correctly (currently, it does not work right at all). Can someone please help me? Any help at all would be greatly appreciated.
Here is my code for my albums controller:
class AlbumsController < ApplicationController
def index
#albums = Album.all
end
def new
#album = Album.new
end
def create
#album = Album.new(album_params)
#album.save
redirect_to albums_path
end
def show
#album = Album.find(params[:id])
end
def edit
end
def update
end
private
def album_params
params.require(:name).permit(:id, :category)
end
end
Also, here is my album model:
class Album < ActiveRecord::Base
belongs_to :user
has_many :photos
end
And here is my migration for the albums:
class CreateAlbums < ActiveRecord::Migration
def change
create_table :albums do |t|
t.string :name # Column for album name of type string
t.string :category # Column for photography category of type string
t.timestamps
end
end
end
Here is my code for my app/views/albums/index.html.erb file:
<div><%= link_to "Admin Access to Add New Album", new_album_path %></div>
<div><%= link_to "Home", root_path %></div>
<h1>Albums Gallery</h1>
<% #albums.each do |album| %>
<div><%= link_to album.name, "/albums/#{album.id}" %></div>
<% end %>
Here is my code from my app/views/albums/new.html.erb file where I use the form_for thing:
<h2>New Albums</h2>
<%= link_to "Back", albums_path %>
<%= form_for (#album) do |f| %>
<div>
<%= f.label :name %>
<%= f.text_field :name %>
</div>
<%= f.submit "Add Album" %>
<% end %>
Everything up to the form_for part where I try to enter a new picture album name works. It's at this point where everything just unravels and won't work for me. Instead of accepting and then showing the new album by name, it displays "/albums/3" when it should display "Nature Scenes". I went into my rails console to see what was going on on the db level and the new albums are not being created and saved correctly. My output from the Rails console looks like this:
2.1.2 :007 > Album.all Album Load (0.2ms) SELECT "albums".* FROM "albums" => #, #, #,
, #
nil, category: nil, created_at: "2014-09-21 02:50:54", updated_at:
"2014-09-21 02:50:54">]>
2.1.2 :008 >
(Sorry about the copy/paste, but being too new at trying to learn how to code, I don't have enough reputation points on Stackoverflow to be allowed to simply post a screenshot yet.)

Answer 1

OK, never mind, I got it. I had the wrong value in the private method. I changed it to
def album_params
params.require(:album).permit(:id,:name, :category)
end
And now the app works fine (at least, so far - I have a long way to go to complete it).
