Question

With Rails, adding columns is easy as this link:

Ruby on Rails: adding columns to existing database

With Redmine Plugin, adding columns for plugin's table seems OK as this link: http://www.redmine.org/boards/2/topics/39008

But in my Redmine Plugin, I want to add columns to Redmine's built-in table (for example, I want to add a column named 'my_own_syntax' to "queries" table). Can I do this?

Answer 1

To add migrations to your plugin create them under

your_newplugin_folder
|- db
   |- migrate
      |-01_fancy_migration.rb

Use numeration for migration files(in filenames but not in class names)

execute em with: rake redmine:plugins:migrate
