is there a gem that builds a visual diagram of your table associations/relationships?

Question

Something that generates an image or something to show that ModelA has_many ModelB etc?

Answer 1

Just found out about Rails ERD.

Looks pretty awesome!

Answer 2

Rubymine can generate that for you. It is an awesome tool.

Answer 3

Try rails_assviz and RailRoad.

One more ancient plugin for zombie lovers is Rails Application Visualizer.

Answer 4

If using rails_assviz then you need to modify the line that loads active support to get it to work by adding /all to: require 'active_support'

Original:

#Checks for active_support
begin
  require 'active_support'
rescue LoadError
  raise "Install the Ruby on Rails gem: gem install rails"
  return false
end

Modified:

#Checks for active_support
begin
  require 'active_support/all'
rescue LoadError
  raise "Install the Ruby on Rails gem: gem install rails"
  return false
end
