    copied!<p>I've got a really weird problem with my project. I've got 2 models, the one is Link and the other Category. I've got a index view where all the links should be listed, together with the corresponding category names. When running the server and trying to use</p> <pre><code>&lt;%= link.category.name %&gt; </code></pre> <p>I get an error page with the following:</p> <pre><code>undefined method `name' for nil:NilClass </code></pre> <p>But when I open the console and write:</p> <pre><code>link = Link.find(1) #there is currently only one link link.category.name </code></pre> <p>It returns the correct category name.</p> <p>Here are my Models and schema.rb:</p> <pre><code>class Link &lt; ActiveRecord::Base attr_accessible :category_id, :description, :title, :url, :visible belongs_to :category scope :visible, lambda { where(visible: true) } end </code></pre> <p>.</p> <pre><code>class Category &lt; ActiveRecord::Base attr_accessible :name has_many :links end </code></pre> <p>.</p> <pre><code>ActiveRecord::Schema.define(:version =&gt; 20130420070717) do create_table "categories", :force =&gt; true do |t| t.string "name" t.datetime "created_at", :null =&gt; false t.datetime "updated_at", :null =&gt; false end add_index "categories", ["id"], :name =&gt; "index_categories_on_id" create_table "links", :force =&gt; true do |t| t.string "title" t.text "description" t.string "url" t.integer "category_id" t.boolean "visible" t.datetime "created_at", :null =&gt; false t.datetime "updated_at", :null =&gt; false end add_index "links", ["category_id"], :name =&gt; "index_links_on_category_id" add_index "links", ["id"], :name =&gt; "index_links_on_id" end </code></pre> <p>How can this happen? Thank you very much for your help!</p>
