Question

I’m trying to run a quick rake task on all my Rails models but haven’t been able to call them because this piece of code tells me that I can’t call the method columns on a string.

I tried classify instead of camelize and it hasn’t worked either, tried inserting a class_eval in there as well, but that dosen’t seem to work here / don’t know too much about it.

task :collect_models_and_field_names => :environment do

models = Dir.glob("#{models_path}/*").map do |m|
  m.capitalize.camelize.columns.each { |n| puts n.name }
end

I do know that this worked so I would have manual access to the model if I needed, but I don’t really want to do that…

  Model.columns.each { |c| puts c.name }

Answer 1

Try

Kernel.const_get(m.classify).columns
