![]() Refer to Ruby Toolbox’s list of Ruby documentation tools for more options. The rendered PDF saves to your application root by default-I check this into my source control for other developers (not to mention for my own reference). Take a look at the gallery of ERD examples from popular open source Rails projects to get a feel for how it works. It’s easy to install, customizable, and very well documented. Rails ERDįinally, how about some visual documentation of how your models relate to one another? Check out Rails ERD a new gem that creates nice PDF entity-relationship diagrams for your apps. method 1: set paths to models using generated rake task ( rails g annotate:install ), look for modeldir there and set paths using comma separator, e.g. Open doc/app/index.html in your browser to access your app’s documentation. Now that you’ve got your models annotated (and have added some descriptive comments to your controllers, right?) you can turn it into browser-friendly HTML using the following built-in Rake task: $ rake doc:appīe sure to also edit the file doc/READ_ME_FOR_APP that’s what the Rake task uses for your documentation’s starter file.

My own Rails project folders are full of uncommented methods and mysterious model attributes. A common knock on the Rails community is that we don’t document our code. If you’ve been using Reek to help in refactoring your Rails applications, you might run across warnings of Irresponsible Modules- that is, code with no comments to help explain what it does. When I run the commands for the Annotate Model Gem to annotate my models I get the following errors and I used these two ways to install the gem: annotate -exclude tests, fixtures c:/Ruby192/li.
