Hi,

I am using 'set_table_name' in all my models, I want one abstract class which extends from ActiveRecord::Base and all my model should extends from this abstract class. i will write setter method in abstrct class which will set table name also i am able to override that method in my model. my question is this is possible in rails? how to implement this in rails?

e.g:-

class Abstract < ActiveRecord::Base   def set_table_name(table_name)      return "prefix" + table_name   end end

class Photo < Abstract     ? From here hoe to make a call for set_table_name end

If all you want to do is add a prefix, I'd just set Abstract.table_name_prefix

try something like this. U need not call set_table_name from child class as long as model name matches with database table using prefix string.

class Abstract < ActiveRecord::Base set_table_name “some_prefix_#{self.to_s.tableize}”

end

If you want to override then

class Photo < Abstract

set_table_name “some_different_table_from regular pattern”

end
