    <p>I am fairly new to Ruby and I fail to see the connection between all those classes and methods. Could you please explain a little what exactly each method does:</p> <pre><code>module Naming # Returns an ActiveModel::Name object for module. It can be # used to retrieve all kinds of naming-related information. def model_name @_model_name ||= begin namespace = self.parents.detect do |n| n.respond_to?(:use_relative_model_naming?) &amp;&amp; n.use_relativve_model_naming? end ActiveModel::Name.new(self, namespace) end end # Returns the plural class name of a record or class. Examples: # # ActiveModel::Naming.plural(post) # =&gt; "posts" # ActiveModel::Naming.plural(Highrise::Person) # =&gt; "highrise_people" def self.plural(record_or_class) model_name_from_record_or_class(record_or_class).plural end # Returns the singular class name of a record or class. Examples: # # ActiveModel::Naming.singular(post) # =&gt; "post" # ActiveModel::Naming.singular(Highrise::Person) # =&gt; "highrise_person" def self.singular(record_or_class) model_name_from_record_or_class(record_or_class).singular end # Identifies whether the class name of a record or class is uncountable. Examples: # # ActiveModel::Naming.uncountable?(Sheep) # =&gt; true # ActiveModel::Naming.uncountable?(Post) =&gt; false def self.uncountable?(record_or_class) plural(record_or_class) == singular(record_or_class) end # Returns string to use while generating route names. It differs for # namespaced models regarding whether it's inside isolated engine. # # For isolated engine: # ActiveModel::Naming.route_key(Blog::Post) #=&gt; post # # For shared engine: # ActiveModel::Naming.route_key(Blog::Post) #=&gt; blog_post def self.singular_route_key(record_or_class) model_name_from_record_or_class(record_or_class).singular_route_key end # Returns string to use while generating route names. It differs for # namespaced models regarding whether it's inside isolated engine. # # For isolated engine: # ActiveModel::Naming.route_key(Blog::Post) #=&gt; posts # # For shared engine: # ActiveModel::Naming.route_key(Blog::Post) #=&gt; blog_posts # # The route key also considers if the noun is uncountable and, in # such cases, automatically appends _index. def self.route_key(record_or_class) model_name_from_record_or_class(record_or_class).route_key end # Returns string to use for params names. It differs for # namespaced models regarding whether it's inside isolated engine. # # For isolated engine: # ActiveModel::Naming.param_key(Blog::Post) #=&gt; post # # For shared engine: # ActiveModel::Naming.param_key(Blog::Post) #=&gt; blog_post def self.param_key(record_or_class) model_name_from_record_or_class(record_or_class).param_key end private def self.model_name_from_record_or_class(record_or_class) (record_or_class.is_a?(Class) ? record_or_class : convert_to_model(record_or_class).class).model_name end def self.convert_to_model(object) object.respond_to?(:to_model) ? object.to_model : object end end end </code></pre> <p>I know there are comments for each method but I still fail to understand basic meta.</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
