WiceGrid 3.6.0.pre4 examples

Joined tables

Use :include in :initialize_grid to include associated tables. :include can be a single association name, an array of association names. If you need to join tables to joined tabes, use hashes, for example: include: [:priority, :status, {project: :customer}]

To define a column from a joined table, use :assoc to specify a the corresponding association. If you need to join a table to a joined table, list associations in an array on the correct order (look at the customer column).

You can drop a block if you don't need any special markup.

  • # encoding: utf-8
    class JoiningTablesController < ApplicationController
      def index
        @tasks_grid = initialize_grid(Task,
          # You can omit includes if they are all mentioned in :assoc in the view
          # includes: [:priority, :status, {project: :customer}],
          conditions: { archived: false },
          order: 'id'
        )
      end
    end
