Hi Tamosus pontik,
Thanks for your reply.
The model file is created dynamically based on this code.
model_file = File.join("app", "models", fname.singularize+".rb")
model_name = fname.singularize.capitalize
File.open(model_file, "w+") do |f|
f << "class #{model_name} < ActiveRecord::Base\nend"
end
But i need to store the values to specific tables.
Note: I am not running migration for the dynamic tables(model)
