【问题描述】:
在我的应用中,用户拥有一个位置,位置属于用户。
user.rb
has_one :location
accepts_nested_attributes_for :location
attr_accessible ... :location_attributes
location.rb
belongs_to :user
attr_accessible :country, :state, :city, :address, :zipcode, :user_id
users_controller(用户是自动创建的,因此没有“新”视图)
def edit
@user = current_user
@user.build_location
end
users/edit.html.haml
= form_for @user do |f|
...
= f.fields_for :location do |location|
%p
= location.label :country
= location.text_field :country
%p
= location.label :state
= location.text_field :state
%p
= location.label :city
= location.text_field :city
%p
= location.label :address
= location.text_field :address
%p
= location.label :zipcode
= location.text_field :zipcode
= f.submit
我收到的错误是“无法批量分配受保护的属性:国家、州、城市、地址、邮政编码。”
我之前遇到过“无法批量分配受保护的属性:location_attribute”类型的错误,但这不是问题所在。
这是我的(删节的)参数:
{"utf8"=>"✓", "_method"=>"put", "authenticity_token"=>"RTpnMsKuByhnGgs9xrX3d0nzKzcaqIcpS75tsujPX2s=", "user"=>{"name"=>"myname", ... "location_attributes"=>{"country"=>"USA", "state"=>"whatever", "city"=>"", "address"=>"", "zipcode"=>""}}, "commit"=>"Update account", "action"=>"update", "controller"=>"users", "id"=>"219"}
知道这里发生了什么吗?我已经搜索了一个 WHILE,但似乎找不到有这个问题的人(everyoneelsehasthe latter mass-assign one)。
【问题讨论】:
-
我认为您不需要将 location_attributes 定义为 attr_accessible
-
愚蠢的想法,但服务器重启? ;)
-
还有 - 那是哪个 Rails 版本?
-
3.2,是的。我试过重启一堆。
