How do I build a JSON object?

Question

Currently I build a JSON object by doing:

@users = User.all

@users.each do |user|
  @userlist << {
    :id => user.id,
    :fname => user.fname,
            


        

Answer 1

json = User.all( :include => :contacts).to_json( :include => :contacts )

Update

Sorry, let me give a more complete answer for what you're doing...

@users = User.all( :include => :contacts )
@userlist = @users.map do |u|
  { :id => u.id, :fname => u.fname, :lname => u.lname, :photo => u.profile_pic.url(:small), :contacts => u.contacts }
end

json = @userlist.to_json

Another Update

Ok, so just forget me - I was having a bad day and totally missed the point of your question. You want some JSON that includes two unrelated sets of data. All the users, and the contacts just for the current user.

You want to create a new hash for that then, something like this...

@users = User.all
@userlist = @users.map do |u|
  { :id => u.id, :fname => u.fname, :lname => u.lname, :photo => u.profile_pic.url(:small) }
end

json = { :users => @userlist, :contacts => current_user.contacts }.to_json

Answer 2

  @userlist = @users.map do |u|
    u.attributes.merge!(:contacts=>current_user.contacts)
  end
  json = @userlist.to_json
