Problem with getting a name string from a query

Question

Hello all,

I'm pretty new to rails and mongoid and I have a problem with extracting a string out of a query.

I have a class Filteroption

class Fieldoption
include Mongoid::Document

field :name, :type => String  
field :option_id, :type => Integer

end

and with this entries

 
+--------------------------+------------------------------------+-----------+  
| _id                      | name                               | option_id |  
+--------------------------+------------------------------------+-----------+  
| 4c6de6a11d41c86698000002 | Request URI                        | 1         |
| 4c6de6a11d41c86698000003 | Hostname                           | 4         |

When I query for the name with the option_id 4

foobar = Fieldoption.only(:name).where(:option_id => '4')

foobar.name should be "Hostname". Instead I get

foobar.name
=> "Fieldoption"

What am I doing wrong ?

Thanks for your help.

The name method is already defined in Ruby to get the class name. You should rename your field to be able to get its content, or try foobar.attributes["name"].
