I want to retrieve the first two records from collection such that, collection is like:
@collect_firstnames = @name.firstnames
From this collection I want to fetch first two records...
I used开发者_开发百科 limit it is not working, :limit => 2
I take it that @name.firstnames
is a has_many
relationship. You need to pass the options to all
:
@name.firstnames.all(:limit => 2)
You can use the :limit option like this:
@first_two = Name.find(:all, :limit => 2)
Edit
It's the same idea, assuming firstnames is a relationship (just like Swanand said below)
@first_two = @name.firstnames.all(:limit => 2)
