Mongoid geben Fehler beim Speichern Feld mit bestimmten Namen

Question

Ich benutze Mongoid in Schienen App. Schienen 3.0.10 Rubin 1.9.2p0

Wenn ich Feld wie "test" Ich versuche, "link", "ab" usw.

Content.new(:test => 'ggg') 

Content.new(:link => 'ggg') 

Content.new(:desc => 'ggg') 

Content-Modell sagen ist, die verwendet "Mongoid :: Document"

gibt es folgenden Fehler. (Dieser Fehler ist für das Feld „test“)

Ich denke mongoid einige Bibliothek verwendet, welche Inhalte über Feldnamen als Funktionen, die

Problem schaffen könnten. Gibt es eine Möglichkeit, dieses Problem zu umgehen?

das neueste alles verwenden, Rubin (1.9.3), Schienen (3.2.3), mongoid (2.4.7) habe ich versucht, die folgenden Dinge:

Modell ohne Set-Felder, die alle dynamischen :

class Content 
    include Mongoid::Document 
end 

Rails-Konsole:

1.9.3p125 :011 > c = Content.new(:test => "test", :link=> "link", :desc => "desc") 
=> #<Content _id: 4f7f49f5add3617fae000003, _type: nil, test: "test", link: "link", desc: "desc"> 
1.9.3p125 :012 > c.save 
=> true 
1.9.3p125 :013 > Content.first 
=> #<Content _id: 4f7f49f5add3617fae000003, _type: nil, test: "test", link: "link", desc: "desc"> 
1.9.3p125 :014 > 

Modell mit allen statisch Satzfelder:

class Content 
    include Mongoid::Document 
    field :test, :type => String 
    field :link, :type => String 
    field :desc, :type => String 
end 

Rails-Konsole wieder:

Loading development environment (Rails 3.2.3) 
1.9.3p125 :001 > c = Content.new 
=> #<Content _id: 4f7f4652add3617ec4000001, _type: nil, test: nil, link: nil, desc: nil> 
1.9.3p125 :002 > c.test = 'tyler' 
=> "tyler" 
1.9.3p125 :003 > c.save 
=> true 
1.9.3p125 :004 > Content.first 
=> #<Content _id: 4f7f4652add3617ec4000001, _type: nil, test: "tyler", link: nil, desc: nil>
