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.


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.

The schema.rb-file should be 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.

There is an issue with namespaced classes. Currently this plugin will try and fetch a class with a namespace if it does not find one at the first try.


Table name        Class name
sales_people      SalesPeople # does not exist
sales_people      Sales::People # does exist

A problem then emerges if you have namespaces with two names.


Table name          Class name
sales_force_people  SalesForcePeople # does not exist
sales_force_people  Sales::ForcePeople # does not exist

The documentation will then be skipped for this table/class.


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 Array<ModelName>.


The plugin handles delegate-methods and marks these delegated instance methods simply as aliases for the associated object.


The plugin will add class methods for any scopes you have defined in your models.
