YARD ActiveRecord Plugin
A YARD extension that handles and interprets methods used when developing applications with ActiveRecord. The extension handles attributes, associations, delegates and scopes. A must for any Rails app using YARD as documentation plugin.
Installation
Run the following command in order to load YARD plugins:
$ yard config load_plugins true
Attributes
In order for this plugin to document any database attributes you need to add
schema.rb to your list of files. This is preferably done with in .yardopts
within your app project folder:
# .yardopts
'app/**/*.rb'
'db/schema.rb'
It's important that the schema.rb-file is added at the end as it needs all
classes loaded before it can add the attributes.
The plugin will then document all attributes in your documentation.
All attributes will be marked as writable. I will update the plugin to include
handling of attr_accessible at a later point.
Please note that any reference-fields that ends with _id will not be handled
as an attribute. Please see Associations.
Associations
The plugin handles has_one, belongs_to, has_many and
has_and_belongs_to_many associations. The annotation for each association
includes a link to the referred model. For associations with a list of objects
the documentation will simply be marked as ActiveRecord::Relation<ModelName>.
Delegates
The plugin handles delegate-methods and marks these delegated instance
methods simply as aliases for the associated object.
Scopes
The plugin will add class methods for any scopes you have defined in your models.
Validations
The plugin will add information about validations onto each field. It only handles the new style validations in the form of:
validates :foo, :presence=>true, :length=>{ is: 6 }
Validations in the older form of:
validates_presence_of :foo
are not supported.
