Excluding column names from a listing

Usually, it is better to make your own view instead of using the 
scaffold, but sometimes it's easier just to use the scaffolding.

What I did was override the content_columns method. Just take the 
source:

 

  ruby 代码
 
 
def content_columns
    @content_columns ||= columns.reject { |c| c.primary || c.name =~
/(_id|_count)$/ || c.name == inheritance_column }
end
And add the column names you want to exclude in the regex with _id and
_count.
