    <p>I am examining the complex_form_example project on github. I modified the migration file so that :content changed from t.text to t.string (as shown below): <strong>Please notice that t.string is the only place I changed in the github example project and before the change it all worked.</strong> </p> <pre><code>class CreateQuestions &lt; ActiveRecord::Migration def self.up create_table :questions do |t| t.integer :survey_id t.string :content ##t.text :content t.timestamps end end def self.down drop_table :questions end end </code></pre> <p>Here is the nested_form_for code:</p> <pre><code>&lt;%= nested_form_for @survey do |f| %&gt; &lt;%= f.error_messages %&gt; &lt;p&gt; &lt;%= f.label :name %&gt;&lt;br /&gt; &lt;%= f.text_field :name %&gt; &lt;/p&gt; &lt;%= f.fields_for :questions, :questions do |g|%&gt; &lt;p&gt; &lt;%= g.label :content, "Question" %&gt;&lt;br /&gt; &lt;%= g.input :content, :rows =&gt; 3 %&gt;&lt;br /&gt; &lt;%= g.link_to_remove "remove" %&gt; &lt;/p&gt; &lt;%= g.fields_for :answers %&gt; &lt;p&gt;&lt;%= g.link_to_add "Add an answer", :answers %&gt;&lt;/p&gt; &lt;% end %&gt; &lt;p&gt;&lt;%= f.link_to_add "Add a question", :questions %&gt;&lt;/p&gt; &lt;p&gt;&lt;%= f.submit "Submit" %&gt;&lt;/p&gt; &lt;% end %&gt; </code></pre> <p>And now I get the following error message:</p> <pre><code>undefined method `content' for :questions:Symbol Extracted source (around line #10): 7: &lt;%= f.fields_for :questions, :questions do |g|%&gt; 8: &lt;p&gt; 9: &lt;%= g.label :content, "Question" %&gt;&lt;br /&gt; 10: &lt;%= g.text_field :content, :rows =&gt; 3 %&gt;&lt;br /&gt; 11: &lt;%= g.link_to_remove "remove" %&gt; 12: &lt;/p&gt; 13: &lt;%= g.fields_for :answers %&gt; </code></pre> <p>My question is, is there a fields_for field name that supports string type directly?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
