Ruby on Rails: testing if ActiveRecord results include a value

Question

After noon,

Suppose I put together a random selection of users:

User.find (: all ,: limit => 10 ,: order => "rand ()")

Now from these results, I want to see if the user with ID 3 was included in the results, what would be the best way to find out?

I thought about Array.include? but it seems to me a dead end.

thanks

Answer 1

users = User.find(:all, :limit => 10, :order => "rand()") users.any? {|u| u.id == 3} 

Answer 2

 assert random_users.include?(User.find 3), "Not found!" 

Active recording objects are considered equal if they have the same identifiers. Array #include? evaluates objects defined by equality using the == method.

Answer 3

User.find (: all ,: limit => 10 ,: order => "rand ()"). any? {| u | u.id == 3}

This will save you from completing another find.
