Standard behavior for the list action is to use content_columns to get all the fields of a model and then do something with them. I''d like to ignore some of them and iteratre over the rest. For instance I may have A B C D ... X Y Z and I''d like to do something special with A and B and then Y and Z, but in the middle I''d definitely like a loop to say "Whatever else is in the middle, here." What''s my option there? content_columns (or column_names) just seems to iterate over everything. I''m currently looking at maybe using "slice" on the result but I haven''t gotten that to work syntactically, yet. Is there a different way? d -- Posted via http://www.ruby-forum.com/.
