导轨中不允许的参数4 [英] Unpermitted parameters in rails 4

问题描述

我阅读了 collection_check_boxes ，但我不明白如何设置选中的值。
我有以下模型：

  class Objective< ActiveRecord :: Base 
 
 has_many：indicators 
 has_many：objective_children，class_name：Objective，foreign_key：parent_id
 
 def objective_ids 
 objective_children。 collect {| o | o.id} 
 end 
 
 def objective_ids = objectives_ids 
 objectives_ids.each do | id | 
 objective_children<< Objective.find（id）
 end 
 end 
 end 
  

编辑视图：

 <％= form_for（@objective）do | f | ％> 
<％= f.collection_check_boxes：objective_ids，Objective.all，：id，：name％> 
<％= f.submit％> 
<％end％> 
  

html复选框都可以，但我不知道如何将值设置为 objective 。我被尝试定义 objective_ids = objectives_ids 但没有发生任何事。

在控制器：

  class ObjectivesController< ApplicationController 
 def objective_params 
 params.require（：objective）.permit（：name，：code，：description，：objective_ids）
 end 
 end 
   
 
 
  EDIT  
日志文件说未授权的参数：perspective_id，objective_ids 
解决方案
我解决了更改行
  params.require（：objective）.permit（：name，：code，：description，：objective_ids）
  
到
  params.require（：objective）.permit ：code，：description，：objective_ids => []）
  
 
I read about collection_check_boxes but I don't understand how can I set the checked values.
I have the following model:
class Objective < ActiveRecord::Base

  has_many :indicators
  has_many :objective_children, class_name: "Objective", foreign_key: "parent_id"

  def objective_ids
    objective_children.collect{|o| o.id}
  end

  def objective_ids= objectives_ids
    objectives_ids.each do |id|
      objective_children << Objective.find(id)
    end
  end
end
edit view:
<%= form_for(@objective) do |f| %>
  <%= f.collection_check_boxes :objective_ids, Objective.all, :id, :name %>
  <%= f.submit %>
<% end %>
the html checkbox are ok but I don't know how to set the values to objective. I was tried define objective_ids= objectives_ids but nothing happens.


In Controller:
class ObjectivesController < ApplicationController
    def objective_params
      params.require(:objective).permit(:name, :code, :description, :objective_ids)
    end
end
EDIT
The log file says Unpermitted parameters: perspective_id, objective_ids
解决方案
I solved changing the line
params.require(:objective).permit(:name, :code, :description, :objective_ids)
to
params.require(:objective).permit(:name, :code, :description, :objective_ids => [])
