    When two associations referring to the same model are joined, ActiveRecord
    uses a table alias for one of these joins. To make it work with WiceGrid, find
    the alias in the logs and specify it in a column definition with the help of

    %code :table_alias
    \.

= show_code

= render   'grid'

<%= grid(@projects_grid, show_filters: :always) do |g|

  g.column name:  'ID', attribute: 'id', filter: false

  g.column name:  'Project Name', attribute: 'name'

  g.column name:  'Customer company', attribute: 'name', assoc: :customer

  g.column name:  'Supplier company', attribute: 'name', assoc: :supplier, table_alias: 'suppliers_projects'
