我有一個設計和康康的小項目設置。有用戶,項目,負責任和任務模型。項目嵌套了任務。每個項目分配給一個或多個用戶。任務模型具有名稱user_id和project_id。身份驗證和授權正在按預期工作。如何將user_id傳遞給nested_resource模型?
當添加一個新的任務(只有名稱輸入)時,project_id會自動傳遞給model/table(我認爲這是因爲路由),但不是user_id。
我是否必須在hidden_field中傳遞user_id或者是否可以在過濾器中設置此項?
有人可以給一個關於如何在taskcontroller中設置user_id的提示嗎?
感謝
# Routes

has_many :tasks, :dependent => :destroy

class Task < ActiveRecord::Base
belongs_to :project
belongs_to :user

# methods removed like explained in cancan manual
class TasksController < ApplicationController

...
def create
respond_to do |format|
if @task.save
format.html { redirect_to [@project, @task], notice: 'created.' }
else
format.html { render action: "new" }
end
end
# Task Form View
<%= semantic_form_for [@project, @task] do |f| %>
<%= f.inputs do %>
<%= f.input :name %>
<% end %>
<%= f.actions %>
<% end %>
更新
看來濾波器之前有工作。這是正確的方式嗎?
class TasksController < ApplicationController
before_filter :set_user, :only => [:create]
load_and_authorize_resource :client
load_and_authorize_resource :task, :through => :client, :shallow => true
...
def set_user()
params[:task][:user_id] = current_user.id.to_s
end
...
