This doesn't really make sense to me. There is only one record for a given value of the id column (or rather rails assumes that id is your primary key) so what were you expecting?

I want all records base on query which i have written in people=People.find(:all, :conditions=>["id=?",params[:id]]) i am getting only one record not all records ...

There is only ever one such record because the primary key is unique (by definition).

I think this is not the real query you are having. you just chose a wrong example

Assuming what u really want is to semulate people=People.find(:all, :conditions=>[“country_id=?”,params[:country_id]])

where country_id is a foreign key to something else

People.find_by_country_id(params[:country_id]) will retrieve only the first record matching the condition.

you should use People.find_all_by_country_id(params[:country_id]) to get all matching results.

hope it helps
