Question

I have some columns that contain a large amount of data (text, etc), and sometimes I am just displaying a summary list of the rows and I don’t want to fetch all that data.

Is there an option to exclude certain columns?

Answer 1

I don’t believe you can exclude certain columns, but you can have ActiveRecord return only specific columns using the :select parameter, e.g.

@articles = Article.find( :all, :select => ‘created_at, title, summary’ )
