    <p>this code could help you...</p> <p>First, create in the lib folder a file named:</p> <pre><code>integer_to_enum.rb </code></pre> <p>In the file put this code:</p> <pre><code>module IntegerToEnum class &lt;&lt; self def included(klass) klass.extend(ModelClassMethods) end end module ModelClassMethods def fields_to_enum(options={}) class_eval &lt;&lt;-end_eval def set_enum_options @enum_options = #{options.inspect} end end_eval options.each_pair do |k,v| class_eval &lt;&lt;-end_eval def #{k.to_s} self.set_enum_options @enum_options[:#{k.to_s}][read_attribute(:#{k.to_s}).to_i] end def #{k.to_s}=(v) self.set_enum_options unless @enum_options[:#{k.to_s}].include?(v) return false end write_attribute(:#{k.to_s}, @enum_options[:#{k.to_s}].index(v)) @#{k.to_s} end end_eval end end end end </code></pre> <p>On the enviroment.rb, put this at the bottom, after 'end'</p> <pre><code>ActiveRecord::Base.send :include, IntegerToEnum </code></pre> <p>And last, in the model you want to 'translate' the Integer field put:</p> <pre><code>class YourModel &lt; ActiveRecord::Base fields_to_enum :appointment_type =&gt; [:unknown, :medical, :trial], :other_field_type =&gt; [:type_a, :type_b, :type_c] end </code></pre> <p>With this, you could do something like: </p> <pre><code>m = YourModel.find(1) m.appointment_type #=&gt; :unknown m.appointment_type = :trial #=&gt; :trial m.save #=&gt; and this will save with the index value of the array definition, since ':trial' is in the 3er position, the sql resulting will save with this number </code></pre> <p>and that all.. hope to help you</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.
