ReQL command: each

Command syntax

cursor.each { ... }
array.each { ... }
feed.each { ... }

Description

Lazily iterate over a result set one element at a time.

RethinkDB sequences can be iterated through via the Ruby Enumerable interface; use standard Ruby commands like each blocks to access each item in the sequence.

Example: Let’s process all the elements!

cursor = r.table('users').run(conn)
cursor.each { |doc|
    process_row(doc)
}

Example: Stop the iteration prematurely and close the connection manually.

cursor = r.table('users').run(conn)
cursor.each do |doc|
    ok = process_row(doc)
    if not ok
        cursor.close()
        break
    end
end
