在对/:username / about发帖时,我收到了“警告:无法批量分配受保护的属性:约”。
class About < ActiveRecord::Base
belongs_to :user

class User < ActiveRecord::Base

end
class AboutsController < ApplicationController
def update
@user = User.first(:conditions => ["lower(username) = ?", params[:username].downcase]) if true
@about = @user.about
if @about.update_attributes(params[:about])
flash[:notice] = "Successfully updated post."
respond_with(@about, :location => about_path(@about.user.username))
else
redirect_to :edit
end
end
end
我正在接受

您需要设置attr_accessible :about_attributes
。
答案 1 :(得分:5)
确保您在About模型中的attr_accessible中提到的about模型中尝试更新的所有字段。
答案 2 :(得分:3)
问题在于参数中的额外about
:"about"=>{"about"=>{"sexuality"...
。
您的表单中可能包含以下内容:
<%= form_for @about do |f| %>
<%= f.fields_for @about do |a| %>
<%= a.text_field :sexuality %>
...
<% end %>
<% end %>
fields_for
阻止导致参数中的额外about
。只需删除它,你应该好好去。

这发生在我身上,因为我在生成器创建模型后通过迁移添加了一列。因此,如果添加列,请编辑模型。
