我有两个模型:
路线和活动
我通过如下迁移在它们之间建立了多对多关系:
class ActivitiesRoutes < ActiveRecord::Migration
def up
create_table :activities_routes, :id => false do |t|
t.integer :route_id
t.integer :activity_id
end
end
end
在休息服务中,我获取路线的数据并获得多项活动,我的模型如下所示:
class Route < ActiveRecord::Base
attr_accessible :activities_attributes
has_and_belongs_to_many :activities
accepts_nested_attributes_for :activities
end
和:
class Activity < ActiveRecord::Base
attr_accessible :activitytext, :iconid
has_and_belongs_to_many :routes
end
在我的应用控制器上,我想做类似的东西:
ruta=Route.create({
#other data for the model
})
ruta.activities_attributes = @activitiesarray #Array made with the Activities received
但我收到一个错误:
undefined method `activities_attributes' for #<Route:0x2bccf08>
如果我像这样离开它:
ruta.activities_attributes << @activitiesarray
我得到:
undefined method `with_indifferent_access' for #<Activity:0x6af7400>
有谁知道我能让这成为可能吗?谢谢 :)
