Abstract superclass for model

Rails
1

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
