保存！蒙古语中引用属性的方法
|
我将Rails 3.0.6与mongoID 2.0.2一起使用。最近，我遇到了保存问题！覆盖setter的方法（我正在尝试创建自己的嵌套属性）。
所以这是模型：
class FeedItem
include Mongoid::Document
has_many :audio_refs
def audio_refs=(attributes_array, binding)
attributes_array.each do |attributes|
if attributes[:audio_track][:id]
self.audio_refs.build(:audio_track => AudioTrack.find(attributes[:audio_track][:id]))
elsif attributes[:audio_track][:file]
self.audio_refs.build(:audio_track => AudioTrack.new(:user_id => attributes[:audio_track][:user_id], :file => attributes[:audio_track][:file]))
end
end
if !binding
self.save!
end
end
class AudioRef
include Mongoid::Document
belongs_to :feed_item
belongs_to :audio_track
end
class AudioTrack
include Mongoid::Document
has_many :audio_refs
mount_uploader :file, AudioUploader
end
it \"Should create audio_track and add audio_ref\" do
@audio_track = Fabricate(:audio_track, :user_id => @author.id, :file => File.open(\"#{Rails.root}/spec/stuff/test.mp3\"))
@feed_item= FeedItem.new(
:user => @author,
:message => {:body => Faker::Lorem.sentence(4)},
:audio_refs => [
{:audio_track => {:id => @audio_track.id}},
{:audio_track => {:user_id => @author.id, :file => File.open(\"#{Rails.root}/spec/stuff/test.mp3\")}}
]
)
@feed_item.save!
@feed_item.reload
@feed_item.audio_refs.length.should be(2)
end
没有找到相关结果

呼叫未使用设置器。 这是方法的源代码，取自APIdock：# File activerecord/lib/active_record/base.rb, line 1396 def initialize(attributes = nil) @attributes = attributes_from_column_definition @attributes_cache = {} @new_record = true @readonly = false @destroyed = false @marked_for_destruction = false @previously_changed = {} @changed_attributes = {} ensure_proper_type populate_with_current_scope_attributes self.attributes = attributes unless attributes.nil? result = yield self if block_given? _run_initialize_callbacks result end
