Question

Using Rails and Mongoid.

It would be easier to put down the code for explaination:

foo = User.all.to_a

Trying to format into acceptable data in my Javascript. But in my iteration:

var dump = []
<%= foo.each do |boop| %>
   dump.push( /*some formatted data using boop/*)
<% end %>

The result dump contains the acceptable format except the document objects are also added at the end of the array.

For instance, using the rails console:

foo.each do |boop|
   print "#{boop.email}\n"
end

Prints out the emails. Then at the end, prints out every single document object in one line.

My output from directly above:

[e-mail]
...
// Prints out emails until end

[#<User _id: 50edd7fe021823ea20000001, _type: nil, email: "[e-mail]", password_digest: "$2a$10$xXixV8MlqGco0Qq7j5jQaOkXBWQ9cLgQ7yEOtQruxq.HiYg8GOJ4y", phone: nil, firstName: nil, lastName: nil, employNum: nil, dateMade: nil, role_id: "50edd7da021823db20000001">, ... #prints out rest of users in line.

The array size and count in db are the same. I also checked the array using last. I’m thinking of using a count iterator by just taking the length of the array, but I’m very curious as to why this is happening.

Answer 1

the print out you’re seeing is the return value of the operation. eg.

> Object.save 
=> true

You can surpress this by passing “;0” after the end of the block which would still print the output but would change the return to zero.

foo.each {|boop| puts "#{boop.email}\n" };0
